instead of HLSL. The current "hack" for shaders
is that the shader string you supply to
Effect::LoadFromFXString requires the lines
// #o3d SplitMarker \n"
Above which is the vertex shader and below which
is the fragment shader.
Since GLSL has no semantics the names are used
for semantics so to get an automatically supplied
worldViewProjection you must name the uniform
worldViewProjection as in
uniform mat4 worldViewProjection
Similarly for attributes (vertex streams) you must
name them to match O3D semantics as in
attribute vec4 texcoord1
attribute vec3 normal
etc.
Included in this is one working sample in
o3d/samples/hellocube-glsl.html
Other things: Added a glsl field to clientInfo
so that a program can check if it needs to supply
GLSL or HLSL. eg client.clientInfo.glsl == true
Updated the O3D libraries to store that info
in o3djs.base.glsl so that the libaries can be
modified to supply GLSL if we want.
Note: To run this on windows you must copy glew32.dll
and glut32.dll to <AppData>...\Mozilla\plugins
To get this to actually work in GLES2 will
require
(*) renaming a few functions
(*) telling O3D there is no NPOT support or if possible
no NPOT support unless the texture has only 1 level.
(*) removing LargeGeometry and FloatingPointTexture support.
(*) Making it link with the GLES2 code

This step does only copies the GL files to
a GLES2 folder. It's still actually the GL renderer
at this point but it's the smallest step for
getting something that builds and a place to
start working.
The next step will be to rename all the
classes from xxxGL to xxxGLES2
At some point CG will be removed as well
One other thing slipped in there. A standalone
build path to help generate a C++ only example
of using O3D. It's currently only a placeholder.
