- Raw to POV-Ray Converter v1.8
- Copyright (c) 1993 Steve Anger
-
- RAW2POV is a utility that converts lists of triangle coordinates in raw
- ascii text format to various raytracer formats. Adjustable levels of smoothing
- can be applied to the triangle surfaces. If you're outputting to POV-Ray 1.0,
- raw2pov will automatically add an efficient set of nested bounding shapes to
- the scene to speed up the rendering.
-
- POV-Ray users! Since POV-Ray 2.0 has now been released to the public the
- default output format has been changed to POV-Ray 2.0. If you're still
- using POV-Ray 1.0 you can still generate 1.0 compatible files by using
- the -op1 switch.
-
-
- File Format:
-
- The triangle data can be organized in one of three formats:
-
- 1) Default - Nine numbers per triangle
-
- Ax Ay Az Bx By Bz Cx Cy Cz
-
- e.g. -3.5 -4.1 -5.0 -3.9 -6.2 -5.0 -3.4 -6.2 -7.0
-
-
- 2) Fractint colour (-fc) - Twelve numbers per triangle
-
- R G B Ax Ay Az Bx By Bz Cx Cy Cz
-
- e.g. 1.0 1.0 0.0 -3.5 -4.1 -5.0 -3.9 -6.2 -5.0 -3.4 -6.2 -7.0
-
-
- 3) Texture names (-ft) - Nine numbers and one texture name per triangle
-
- Ax Ay Az Bx By Bz Cx Cy Cz TEXTURE
-
- e.g. -3.5 -4.1 -5.0 -3.9 -6.2 -5.0 -3.4 -6.2 -7.0 RedPlastic
-
-
- Ax, Ay, etc are the x,y,z coordinates of the three triangle vertices A, B,
- and C. R, G, and B represent the Red, Green, and Blue components of the
- triangle colour and range from 0.0 to 1.0. TEXTURE is a string indicating
- the texture name. The numbers/names can be separated by spaces, tabs, or
- carriage returns.
-
- Non-numeric identifiers can be used to separate groups of triangles
- representing different objects. See CHESS.RAW for an example.
-
-
- Hardware Requirements:
-
- Two version of the executable are included in this archive, RAW2POV.EXE and
- RAW2POVX.EXE. The first version will run on all machines from XT's to 486's
- but is only capable of using 640k of memory. The second version requires a
- minimum of a 386 with a co-pro to run but can use all available memory plus
- up to 128M of virtual memory.
-
-
- Usage: raw2pov inputfile[.raw] [outputfile] [options]
-
- Options:
-
- -snnn - Generates smooth triangles. The boundary between triangles are only
- smoothed if the angle between the triangles is less that nnn deg.
- -s0 will not smooth any triangles while -s180 will smooth all
- triangles. Values from -s45 to -s90 usually work well. If
- unspecified smoothing defaults to -s70.
-
- +v, -v - Turn verbose status messages on or off. Messages are off by default.
-
- +i, -i - Turn internal bounding on or off for POV-Ray. By default internal
- bounding is on for POV-Ray 1.0 output and off for POV-Ray 2.0 output.
-
- -1 - Bound all of the input objects as a single object. By default all
- objects are bounded separately and then combined. This option may
- produce better results in some cases, especially if the input file
- contains a large number of very small objects.
-
- -x - Exchanges the Y and Z coordinates of all triangle vertices. Useful
- if the input file was generated from a program that uses the Z
- coordinate as vertical rather that the Y coord as is normally used in
- POV-Ray.
-
- -c - Adds a camera and a light source to the scene. The camera is
- automatically adjusted to frame the object.
-
- -fc - Specifies that the input file is in Fractint style colour format
- with 12 numbers per triangle.
-
- -ft - Specified that the input file contains texture names.
-
- -op - Output to POV-Ray 1.0 format (default).
- -op2 - Output to POV-Ray 2.0 format (2.0 is unreleased as yet).
- -ov - Output to Vivid 2.0 format.
- -ol - Output to Polyray format.
-
-
- Examples:
-
- // Convert CHESS.RAW to POV-Ray 2.0 format.
- raw2pov chess
-
- // Convert CHESS.RAW to POV-Ray 1.0 format. Add a camera and light.
- raw2pov chess -op1 -c
-
- // Convert CHESS.RAW to Vivid format with Y and Z axis' swapped
- raw2pov chess -ov -x
-
- // Convert CHESS.RAW to POV-Ray format with full smoothing and a new name
- raw2pov chess melted -s180
-
- Note: Smooth triangles will only work properly if the input file uses
- consistent clockwise or counter-clockwise vertex ordering. Most CAD packages
- that output triangular data will already have the data in the proper order.
-
-
- Environment Variable:
-
- If you find that you're often using the same command line options over and
- over again you can set up your default command line options in the RAW2POV
- environment variable. e.g. If you always want to have a camera and light
- added to your scene you may want to add the following line to your
- autoexec.bat:
-
- set RAW2POV=-c
-
- Commands specified in the environment variable will be overridden by those
- specified on the command line.
-
-
-
- Revision History:
-
- Changes in v1.8
- - Added POV-Ray 2.0, Vivid 2.0, and Polyray output.
- - Default smoothing changed from 60 degrees to 70 degrees.
- - A couple changes to the command line options.
- - Doesn't choke on decimal numbers with no leading zero (e.g. ".25")
- - RAW2POV environment variable added.
-
- Changes in v1.7
- - The -ft option in 1.6 just plain didn't work (oops).
- - The -c option will automatically add a camera an light source to the scene.
- - Fixed a bug that occasionally generated a bad smooth triangle normal.
-
- Changes in v1.6
- - Put the named texture feature back in with a command line option to turn
- it on (-ft). A few people missed it.
-
- Changed in v1.5
- - Outputs POV-Ray 1.0 format files only.
- - Uses the new box primitive available in POV-Ray 1.0 as a bounding shape.
- - Accepts unformatted input rather than the one triangle per line format
- used with previous versions.
-
- Changes in v1.4
- - Name changed from TXT2POV to RAW2POV.
- - Now outputs only lower case keywords. I'll assume nobody's using DKB any
- more.
- - Allows you to swap the Y and Z axis when converting for those files that
- use the Z coord as vertical.
- - Automatically removes illegal characters in object/texture names.
- - Better rejection of degenerate triangles.
- - Little bug fixes here and there.
-
- Changes in v1.3
- - Name changed from TXT2DKB to TXT2POV although the version number was not
- reset. The output files should be compatible with both DKB 2.12 and POV
- 0.50 beta.
- - Nothing new as far as faster rendering times. :(
- - The graphic preview was getting to be a pain to maintain in this version so
- I dropped it.
- - Protected mode compile (TXT2POVX) is now VCPI compliant and should work
- with most 386 memory managers. Desqview and Windows are still no-no's.
- - Now outputs both a data (.dat) file and a separate include (.inc) file
- instead of one big data file.
- - Generated files are about 30% smaller.
- - You can now specify object and texture names in the input file.
-
- Changes in v1.2:
- - Added nested bounding shapes for improved rendering times (especially for
- very large objects). Uses a mangled version of the octree method.
- - Bounding shapes optionally shown in preview.
-
- Changes in v1.1:
- - The optimization routines can now handle input files that contain very
- large numbers of different colours such as those generated by Fractint.
