- 11. Background imagery/textures/datafiles
- -----------------------------------------
-
- a. Check in the FTP places that are mentioned in the FAQ.
-
- b. Get a good 24-bit scanner, like Epson's. Suggested is an SCSI port for
- speed. Eric Haines had a suggestion in RT News, Volume 4, #3 :
- scan textures for wallpapers and floor coverings, etc. from doll
- house supplies.
- So you have a rather cheap way to scan patterns that don't have
- scaling troubles associated with real materials and scanning area..
-
- c. Find some houses/books/magazines that carry photographic material.
- Educorp, 1-619-536-9999, sells CD-ROMS with various imagery - also
- a wide variety of stock art is available.
- Stock art from big-name stock art houses, such as Comstock,
- UNIPHOTO, and Metro Image Base, is available.
-
- In Italy, there's a company called Belvedere that makes such books
- for the purpose of clipping their pages for inclusion in your
- graphics work. Their address is:

- 12. Introduction to rendering algorithms
- ----------------------------------------
-
- a. Ray-Tracing:
-
- I assume you have a general understanding of Computer Graphics. No? Then read
- some of the books that the FAQ contains. For Ray-Tracing, I would
- suggest:
- An Introduction to Ray Tracing, Andrew Glassner (ed.), Academic Press
- 1989, ISBN 0-12-286160-4
- Note that I have not read the book, but I feel that you can't be wrong
- using his book. An errata list was posted in comp.graphics by Eric Haines
- (erich@eye.com)
-
- There's a more consise reference also:
-
- Roman Kuchkuda , UNC @ Chapel Hill: "An Introduction to Ray Tracing", in
- "Theoretical Foundations for Computer Graphics and CAD", ed. R.A.E.Earnshaw,
- NATO AS, Vol. F-40., pp. 1039-1060. Printed by Springer-Verlag, 1988.
-
- It contains code for a small, but fundamentally complete ray-tracer.
-
- b. Z-buffer (depth-buffer)
-
- A good reference is:
-
- _Procedural Elements for Computer Graphics_, David F. Rogers,
- McGraw-Hill, New York, 1985, pages 265-272 and 280-284.

- 13. Where can I find the geometric data for the:
- ------------------------------------------------
-
- a. Teapot ?
- -----------
-
- I suggest you read the "Displays on Display" column of IEEE CG&A, Jan. '87.
- It contains an account from Frank Crow of the whole story, plus the data
- and a Pascal program to display them. The data were without structure ie.
- polygons.
-
- Jim Blinn had another article in "Jim Blinn's Corner" in the same magazine,
- Sep. '87, in which he lists the teapot data as control points for Bezier
- patches.
-
- The OFF and SPD packages have these objects, so you're advised to get
- them to avoid typing the data yourself. The OFF data is triangles at
- a specific resolution (around 8x8[x4 triangles] meshing per patch).
- The SPD package provides the spline patch descriptions and performs a
- tessellation at any specified resolution.
-
- b. Space Shuttle ?
- ------------------
-
- Tolis Lerios <tolis@nova.stanford.edu> has built a list of Space Shuttle
- datafiles. Here's a summary (From his sci.space list):
-
- model1:
- A modified version of the newsgroup model (model2)
-
- 406 vertices (296 useful, i.e. referred to in the polygon descriptions.)
- 389 polygons (233 3-vertex, 146 4-vertex, 7 5-vertex, 3 6-vertex).
- Payload doors non-existent.
- Units: unknown.
-
- Simon Marshall (S.Marshall@sequent.cc.hull.ac.uk) has a copy. He
- said there is no proprietary information associated with it.
-
- model2:
- The newsgroup model, in OFF format. You can find it in
-
- gondwana.ecr.mu.oz.au , file pub/off/objects/shuttle.geo
- hanauma.stanford.edu , /pub/graphics/Comp.graphics/objects/shuttle.data
-
- model3:
- The triangles' model.
-
- This model is stored in several files, each defining portions of the model.
-
- Greg Henderson (henders@infonode.ingr.com) has a copy. He did
- not mention any restriction on the model's distribution.
-
- model4:
- The NASA model.
-
- The file starts off with a header line containing three real numbers,
- defining the offsets used by Lockheed in their simulations:
-
- <x offset> <y offset> <z offset>
-
- From then on, the file consists of a sequence of polygon descriptions
-
- 3473 vertices.
- 2748 polygons (407 3-vertex, 2268 4-vertex, 33 5-vertex, 14 6-vertex,
- 10 7-vertex, 8 8-vertex, 8 12-vertex, 2 13-vertex, 2 15-vertex,
- 17 16-vertex, 2 17-vertex, 2 18-vertex, 3 19-vertex, 8 24-vertex).
- Payload doors closed.
- Units: inches.
-
- Jon Berndt (jon@l14h11.jsc.nasa.gov) seems to be responsible for the model
- Proprietary info: unknown
-
- model5:
- The old shuttle model.
-
- The file consists of a sequence of polygon descriptions.
-
- 104 vertices.
- 452 polygons (11 3-vertex, 41 4-vertex).
- Payload doors open.
- Units: meters.
-
- We have been using this model at STAR Labs, Stanford University, for
- some years now. Contact me (tolis@nova.stanford.edu) or my supervisor
- Scott Williams (scott@star5.stanford.edu) if you want a copy.

- 14. Plotting packages
- ---------------------
-
- Gnuplot 3.2
- -----------
- It is one of the best 2- and 3-D plotting packages, with
- online help.It's a command-line driven interactive function plotting utility
- for UNIX, MSDOS, and VMS platforms. Freely distributed, it supports many
- terminals, plotters, and printers and is easily extensible to include
- new devices. It was posted to comp.sources.misc in version 3.0, plus
- 2 patches.
- You can practically find it everywhere.
-
- Xvgr and Xmgr (ACE/gr)
- -----------------------
- Xmgr is an XY-plotting tool for UNIX workstations using
- X or OpenWindows. There is an XView version called xvgr for
- Suns. Collectively, these 2 tools are known as ACE/gr.

- 15. Image analysis software - Image processing and display
- ----------------------------------------------------------
-
- [ MAJOR reorganization + additions! ]
- [ Here I include a half baked list from ritley@uimrl7.mrl.uiuc.edu (Kenneth
- Ritley) on such softare, plus additions from Stephen L. Pendergast's
- <penderga@HAC2ARPA.HAC.COM> list, which was derived in turn from Tim Allen's
- <tim.allen@dartmouth.edu> list -- phew!! and various other sources here and
- there. Also I tried to make a major reorganization under the various platform
- categories . Still don't know how to separate the Remote Sensing stuff
- Any ideas?? -- nfotis ]
-
- PC and Mac-based tools (multi-platform software)
- ======================
-
- IMDISP
- ------
- IMDISP Written at JPL and other NASA sites. Can do simple display,
- enhancing, smoothing and so on. Works with the FITS and VICAR/PDS
- data formats of NASA. Can read TIFF images, if you know their dimensions
- [PC and Macs]
-
- LabVIEW 2
- ---------
- LabVIEW is used as a framework for image processing tools. It provides a
- graphical programming environment using block diagram sketch is the
- "program" with graphical elements representing the programming elements.
- Hundreds of functions are already available and are connected using a
- wiring tool to create the block diagram (program). Functions that the
- block diagrams represent include digital signal processing and
- filtering, numerical analysis, statistics, etc. The tool allows any
- Virtual Instrument (VI, a software file that looks and acts like a real
- laboratory instrument) to be used as a part of any other virtual
- instrument.
-
- National Instruments markets plug-in digital signal processing (DSP)
- boards for Macintoshs and PC compatables that allow real-time
- acquisition and analysis at a personal computer. New software tools for
- DSP are allowing engineers to harness the power of this technology. The
- tools range from low-level debugging software to high-level block
- diagram development software. There are three levels of DSP programming
- associated with the NB-DSP2300 board and LabVIEW:
- Use of the NB-DSP2300 Analysis Library: FFTs, power spectra, filters
- routines callable from THINK C and Macintosh Programers Workshop (MPW) C
- that execute on the NB-DSP2300 board. There is an analysis Virtual
- Interface Library of ready-to-use VIs optimized for the NB-DSP2300.
-
- Use of the National Instruments Developers Toolkit that includes an
- optimizing C compiler, an assembler and a linker for low-level
- programming of the DSP hardware. This approach offers the highest level
- of performance but is the must difficult in terms of ease of use.
-
- Use of the National Instruments Interface Kit software package which has
- utility functions for memory management data communications and
- downloading code to the NB-DSP2300 board. (This is the easiest route for
- the development of custom code.)
-
- Ultimage Concept VI
- -------------------
- Concept VI by Graftek-France is a family of image processing Virtual
- Instruments (VIs) that give LabVIEW 2 (described above) users high-end
- tools for designing, integrating and monitoring imaging control systems.
- A VI is a software file that looks and acts like a real laboratory
- instrument. Typical applications for Concept VI include thermography,
- surveillance, machine vision, production testing, biomedical imaging,
- electronic microscopy and remote sensing.
-
- Ultimage Concept VI addresses applications which require further
- qualitative and quantitative analysis. It includes a complete set of
- functions for image enhancement, histogram equalization, spatial and
- frequency filtering, isolation of features, thresholding, mathematical
- morphology analysis, density measurement, object counting, sizing and
- characterization.
-
- The program loads images with a minimum resolution of 64 by 64, a pixel
- depth of 8, 16, or 32 bits, and one image plane. Standard input and
- output formats include PICT, TIFF, SATIE, and AIPD. Other formats can
- be imported.
-
- Image enhancement features include lookup table transformations, spatial
- linear and non-linear filters, frequency filtering, arithmetic and logic
- operations, and geometric transformations, among others. Morphological
- transformations include erosion, dilation, opening, closing, hole
- removal, object separation, and extraction of skeletons, among others.
- Quantitative analysis provides for objects' detection, measurement, and
- morphological distribution. Measures include area, perimeter, center of
- gravity, moment of inertia, orientation, length of relevant chords, and
- shape factors and equivalence. Measures are saved in ASCII format. The
- program also provides for macro scripting and integration of custom
- modules.
-
- A 3-D view command plots a perspective data graph where image intensity
- is depicted as mountains or valleys in the plot. The histogram tool can
- be plotted with either a linear or logarithmic scale. The twenty-eight
- arithmetic and logical operations provide for: masking and averaging
- sections of images, noise removal, making comparisons, etc. There are
- 13 spatial filters that alter pixel intensities based on local
- intensity. These include high-pass filters for contrast and outlines.
- The frequency data resulting from FFT analysis can be displayed as
- either the (real , imaginary ) components or the (phase, magnitude)
- data. The morphological transformations are useful for data sharpening
- and defining objects or for removing artifacts.
-
- The transformations include: thresholding, eroding, dilating and even
- hole filling.
-
- The program's quantitative analysis measurements include: area,
- perimeter, center of mass, object counts, and angle between points.
-
- GTFS, Inc. 2455 Bennett Valley Road #100C Santa Rosa, CA 95494
- 707-579-1733
-
- IPLab Spectrum
- --------------
- IPLAB Spectrum supports image processing and analysis but lacks the
- morphology and quantitative analysis features provided by
- Graftek-FranceUs Ultimage Concept VI. Using scripting tools, the user
- tells the system the operations to be performed. The problem is that far
- too many basic operations require manual intervention. The tool
- supports: FFTs, 16 arithmetic operations for pixel alteration, and a
- movie command for cycling through windows.
-
-
- Macintosh-based tools
- =====================
-
- NCSA Image, NCSA PalEdit and more
- ---------------------------------
- NCSA provides a whole suite of public-domain visualization tools for the
- Macintosh, primarily aimed at researchers wanting to visualize results
- from numerical modelling calculations. These applications,
- documentation, and source code are available for anonymous ftp from
- ftp.ncsa.uiuc.edu. Commercial versions of the NCSA programs have been
- developed by Spyglass.

- NIH IMAGE
- ---------
- Available at alw.nih.gov (128.231.128.7) or (preferably)
- zippy.nimh.nih.gov [128.231.98.32], directory:/pub/image.
- It has painting and image manipulation tools, a macro language,
- tools for measuring areas, distances and angles, and for counting
- things. Using a frame grabber card, it can record sequences of
- images to be played back as a movie. It can invoke user-defined
- convolution matrix filters, such as Gaussian. It can import raw
- data in tab-delimited ASCII, or as 1 or 2-byte quantities. It also
- does histograms and even 3-D plots. It is limited to 8-bits/pixel,
- though the 8 bits map into a color lookup table. It runs on any Mac
- that has a 256-color screen and a FPU (or get the NonFPU version
- from zippy.nimh.nih.gov)

- software) for scientific image processing and analysis. Video-rate
- capture, display, processing, and analysis of high-resolution
- monochromatic and color images. Includes C source code."
-
- TCL-Image:
- "Software package for scientific, quantitative image processing and
- analysis. It provides a complete language for the capture, enhancement,
- and extraction of quantitative information from gray-scale images.
- TCL_Image has over 200 functions for image processing, and contains the
- other elements needed in a full programming language for algorithm
- development -- variables and control structures. It is easily
- extensible through "script" (or indirect command) files. These script
- files are simply text files that contain TCL-Image commands. They are
- executed as normal commands and include the ability to pass parameters.
- The direct capture of video images is supported via popular frame
- grabber boards. TCL-Image comes with the I-View utility that provides
- conversion between common image file types, such as PICT2 and TIFF."

-
- Satellite Image Workshop
- ------------------------
- It comes with a number of satellite pictures (raw data) and does all
- sorts of image enhancing on it. You'll need at least a Mac II with co-
- processor; a 256 color display and a large harddisk. The program doesn't
- run under system 7.x.ATE1 V1

- analysis and scientific 2D and 3D plotting."
-
- Paragon Imagine 171 Lincoln St. Lowell, MA 01852 508-441-2112
-
- Adobe Photoshop
- ---------------
-
- The tool supports Rtrue colorS with 24-bit images or 256 levels of grey
- scale. Once an image has been imported it can be Rre-touchedS with
- various editing tools typical of those used in Macintosh-based RpaintS
- applications. These include an eraser, pencil, brush and air brush.
- Advanced RpasteS tools that control the interaction between a pasted
- selection and the receiving site have also been incorporated. For
- example, all red pixels in a selection can easily be preventing from
- being pasted. Photoshop has transparencies ranging from 0 to 100%,
- allowing you to create ghost overlays. RPhoto-editingS tools include
- control of the brightness and contrast, color balancing, hue/saturation
- modification and spectrum equalization. Images can be subjected to
- various signal processing algorithms to smooth or sharpen the image,
- blur edges, or locate edges. Image scaling is also supported.
-
- For storage savings, the images can be compressed using standard
- algorithms, including externally supplied compression such as JPEG,
- availlable from Storm Technologies. The latest version of Adobe
- Photoshop supports the import of numerous image formats including: EPSF,
- EPSF, TIFF, PICT resource, Amiga IFF/ILBM, CompuServe GIF, MacPaint,
- PIXAR, PixelPaint, Scitex CT, TGA and ThunderScan..

- ColorStudio and ImageStudio
- ---------------------------
- ColorStudio is an image-editing and paint package from Letraset that has
- more features than Adobe Photoshop but is decidedly more complex and
- therefore more difficult to use. Several steps are often required to
- accomplish that which can be done in a single step using Photoshop. The
- application requires a great deal of available disk space as one can
- easily end up with images in the 30 MB range. The program provides a
- variety of powerful selection tools including the "auto selection tool"
- which lets the user choose image areas on the basis of color, close
- hues, color range and mask.

- Digital Darkroom
- ----------------
- The latest release of Digital Darkroom has five new selection and
- editing tools for enhancing images. One such feature allows the user to
- select part of an image simply by "painting" it. A new polyline
- selection tool creates a selection tool for single pixel wide
- selections. A brush lets the operator "paint" with a selected portion
- of the image. Note that this is not a true color image enhancement tool.
- This tool should be used when the user intends to operate in grey-scale
- images only. It should be noted that Digital Darkroom is not as
- powerful as either Adobe Photoshop or ColorStudio.

- Dimple
- ------
- It is compatible with system 6.05 and system 7.0 , requires Mac LC or
- II series with 256 colours, with a recommended min of 6Mb of ram. It has
- the capability of reading Erdas files. Functions include; image
- enhancement, 3D and contour plots, image statistics, supervised and
- unsupervised classification, PCA and other image transformations. There
- is also a means (Image Operation Language or IOL) by which you can write
- your own transformations. There is no image rectification, however
- Dimple is compatable with MAPII. The latest version is 1.4 and it is in
- the beta stage of testing. Dimple was initially developed as a teaching
- tool and it is very good for this purpose."
-
- "Dimple runs on a colour Macintosh. It is a product still in its
- development phase.. i.e. it doesn't have all the inbuilt features of
- other packages, but is coming along nicely. It has its own inbuilt
- language for writing "programs" for processing an image, defining
- convolution filters etc. Dimple is a full mac application with pull down
- menus etc... It is unprotected software."

- Image Analyst
- -------------
- An image processing product for users who need to extract quantitative
- data from video images. Image Analyst lets users configure
- sophisticated image processing and measurement routines without the
- necessity of knowing a programming language. It is designed for such
- tasks at computing number and size of cells in images projected by video
- cameras attached to microscopes, or enhancing and measuring distances in
- radiographs.
-
- Image Analyst provides users with an array of field-proven video
- analysis techniques that enable them to easily assemble a sequence of
- instructions to enhance feature appearance; count objects; determine
- density, shape, size, position, or movement; perform object feature
- extraction; and conduct textural analysis automatically. Image Analyst
- works with either a framegrabber board and any standard video camera, or
- a disk-stored image.
-
- Within minutes, without the need for programming, the Image Analyst user
- can set up a process to identify and analyze any element of a image.
- Measurements and statistics can be automatically or semi-automatically
- generated from TIFF or PICT files or from captured video tape images.
- Image Analyst recognizes items in images based on their size, shape and
- position. The tool provides direct support for the Data Translation and
- Scion frame grabbers. A menu command allows for image capture from a VCR
- video camera or other NTSC or PAL devices.
