Introduction
The current version is 1.62, for Windows 32 bit. LGPL license!
Linux version : I'm working on the assembly part.

This page contains a library called "glh" which stands for Graphics Library Helper. It is kind of like OpenGL's GLU but contains extra functions and optimized functions. The optimizations are done with assembly and are for the x86 architecture. Note that not all parts are done in assembly.

glhlib is still freeware and still contains the very fast image scaling function --> glhScaleImage_asm386
the function that started this project.

PS: For Windows, glhlib is compiled with VC++6 SP5, for Pentium Pro, Maximize Speed.
For Linux, gcc is used (gcc -fPIC -fomit-frame-pointer -g -c XXXX.cpp to compile .cpp to .oand
gcc -shared -W1, -glhlib,glhlib.so.156 -o glhlib.so.156 XXXXX.o to link .o into a shared library)

Version 1.62
GL 3.0 has been released. Quite a few functions in GL are considered old and not necessary therefore GLH functions that were calling those same functions such as glMatrixMode, glFrustum, glOrtho, glLoadMatrixf, glAccum ARE NOW REMOVED.
The accumulation buffer is useless now that we have floating point render targets and you can do DOF just as well.
Don't worry, there are still other functions that can do the same job such as glhLoadIdentityf2, glhFrustumf2 and many others.

Deleting :
glhPerspectived
glhPerspectivef
and several other functions (Block 13)

Deleting :
glhAccumFrustumf, glhAccumPerspectivef, glhRender_DOF_SceneAAf

Version 1.61
Bug fix in glhCreateSpheref2. In class TSphere, GenerateVertices() and GenerateVertices2() were
not computing the vertices correctly. The z values wasn't taking the radius into account, so when the sphere
radius is 1.0, then it looks ok, else the sphere looks deformed.
Bug fix in glhGetIntegerv. When you call glhGetIntegerv(GLH_OPENGL_VERSION, params), the minor number returned was incorrect.

Version 1.60
Deleting :
glhGetFloat
glhGetOpenGLMainVersion
glhGetGLSLMainVersion
glhGetShaderModel
glhIsRunningInHardwareMode
====Use glhGetIntegerv instead

Deleting :
glhGetOpenGLMainVersionAsString
glhGetGLSLMainVersionAsString
glhGetGLUMainVersionAsString
glhGetOpenGLSubVersionAsString
glhGetOpenGLDriverVersionAsString
glhGetShaderModelAsString
====Use glhGetString instead

Happy New Year!
I made a small change.
Added glhQuaternionQuatToRotationMatrixTf
Current version is 1.58 for Windows, 32 bit.
Doing some work on the Linux version as well.

Older logs have been deleted else this page would be too long.
