- What's New in POV-Ray 2.2
- --------------------------
-
- This bug-fix release adds no new features but fixes the following
- bugs from version 2.1.
-
- - Fixed problem with declared material_maps or declared objects with
- material_maps (yet again)
- - Eliminated unnecessary turbulence calculations in normals
- - Fixed all known problems with height fields
- - Fixed IBM.C problems for Watcom compiler DPMI support
- - Added Symatec C compiller make files for IBM version
- - New video modes added to Amiga version
-
- What's New in POV-Ray 2.1
- --------------------------
-
- This bug-fix release adds no new features but fixes the following
- bugs from version 2.0.
-
- - Fixed problem in OBJECTS.C that caused problem on some Unix compilers
- - Fixed problem with declared material_maps or declared objects with
- material_maps
- - Fixed IBM.C problems for Zortech compiler
- - Created temporary fix for problems with normals, smooth triangles
- beziers and height fields which created unsightly black spots
- - Allows scale <-1,1,1> to work with boxes
- - Cleared up inconsistency with -sr, -sc, -er, -ec numbering. Upper
- left pixel is 1,1. Fixed -ec bug.
- - Fixed three bezier patch bugs which caused lock-ups, missing reflection,
- and triangle dropouts.
- - Eliminated some restrictions on multiple clipped_by and bounded_by
- - Fixed compiler problems on VMS/VAX
- - Fixed scaling bug on degenerate triangles
- - Fixed problem with water_level when using +MV1.0
- - Fixed problem with color maped TGA height fields
-
- What's New in POV-Ray 2.0
- -------------------------
- The following is not intended to be an all-inclusive list of every
- new feature, but should give experienced users a pretty good guide
- of what has been changed and what has been added. Please refer to
- POVRAY.DOC for details.
-
-
- General:
- -------
- - Automatic bounding slabs for greatly enhanced rendering speed of
- most scenes.
- - Adding, subtracting, multiplying & dividing of floats & vectors.
- - Clock global variable for external animation support.
- - X, Y, and Z global vector constants.
- - Improved antialiasing routine with new commandline options.
-
- Commandline options:
- -------------------
- - Version switch for backwards compatibility.
- - Starting/ending column/row switches for trace window.
- - Relative/absolute values for trace window switches.
- - Antialiasing jitter scale value and toggle.
- - Number of antialiasing rays to shoot.
- - Internal "clock" setting for animations.
-
-
- Objects:
- -------
- - Soft penumbral shadows from extended area lights.
- - Smoother Bezier patches.
- - New simplified torus syntax.
- - Heightfield water_level now uses range 0-1 instead of 0-255.
- - Heightfields can now be clipped and used in CSG operations.
- - Heightfields can be phong-shaded with the "smooth" option.
- - New, improved finite cylinders, cones, and discs, with
- optional "capping" of cones and cylinders.
- - More versatile CSG unions have replaced the need for composites.
- - CSG texturing has been made much more flexible.
- - New "merge" removes internal boundaries between transparent
- unioned objects.
-
- Textures:
- --------
- - Hexagon pigment texture.
- - Radial pigment texture.
- - Mandelbrot pigment texture.
- - Texture attributes grouped into 3 independently scalable groups:
- pigment, normal, and finish.
- - TIR (Total Internal Reflection) for more realistic refraction.
- - Fractional Brownian Motion (fbm) turbulence controls.
- - Turbulence can now be used independently with any pigment or normal
- texture.
- - Optional vector-style turbulence values.
- - Background coloring.
- - Color maps can now be declared.
- - Frequency, phase keywords now available for use with color_maps.
- - Filter keyword replaces "alpha", letting us reserve alpha for other
- uses in the future.
- - Less restrictive distribution policy. See POVLEGAL.DOC for
- details.
-
- IBM PC Video:
- ------------
- - VESA 1.2 spec implemented for preview graphics in the IBM DOS version.
- Gives VESA support in most 8/15/24 bit modes.
- Should support: 1024 x 768 x 256 color palette
- 800 x 600 x 15 bit high color
- 640 x 480 x 24 bit true color
- - Diamond 24X 15 and 24 bit mode support added.
- - Preview reduced to fit selected video screen size if necessary.
