MathMod is a mathematical modeling software
...: "Complex3D_xx" and "Complex4D_Saddle")
2) Added support for HSV (hue, saturation, lightness) coloring model (script: "Complex_Domain_Coloring")
3) Texture definitions (RGB and HSV) for parametric surfaces can now be expressed as functions of complex numbers
4) Added a software implementation for the OpenGL variable gl_FrontFacing (fixed an issue with GPU drivers on MacOSX Catalina).
The activation of this patch is available from mathmodconfig.js ("OpenGlConfig"-->"GL_FrontFacingSup
