[osg-users] OpenGL ES 2.0 on windows
Hi Robert,
working with OpenGL ES 2.0 with Angle ( I also checked ATI OpenGL ES SDK )
with osg 3.2
I have a warning Detected OpenGL error invalid enumerant on this line in
State.cpp
glGetIntegerv(GL_MAX_TEXTURE_COORDS,_glMaxTextureCoords);
( in following part of code in function void
State::initializeExtensionProcs() )
if ( osg::getGLVersionNumber() = 2.0 ||
osg::isGLExtensionSupported(_contextID,GL_ARB_vertex_shader) ||
OSG_GLES2_FEATURES)
{
glGetIntegerv(GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS,_glMaxTextureUnits);
glGetIntegerv(GL_MAX_TEXTURE_COORDS,_glMaxTextureCoords);
}
I asked Angle project list that maybe they are wrong here ( but still ATI
ES SDK also lacks GL_MAX_TEXTURE_COORDS ) and they responded they are not,
the GL_MAX_TEXTURE_COORDS is underfined for OpenGL ES 2.0
So, possibly here there should be a code like
if ( osg::getGLVersionNumber() = 2.0 ||
osg::isGLExtensionSupported(_contextID,GL_ARB_vertex_shader) ||
OSG_GLES2_FEATURES)
{
glGetIntegerv(GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS,_glMaxTextureUnits);
if(OSG_GLES2_FEATURES)
{
_glMaxTextureCoords = _glMaxTextureUnits;
}
else
glGetIntegerv(GL_MAX_TEXTURE_COORDS,_glMaxTextureCoords);
}
?
Best regards
Sergey

Re: [osg-users] OpenGL ES 2.0 on windows
Hi Sergey,
You suggested change looks reasonable. Curious that others including
myself haven't spotted this error so I can only presume that quite a
few GLES implementations do indeed included support for
GL_MAX_TEXTURE_COORDS. Once you have the code working cleanly could
you post the modified file to osg-submissions.
Thanks,
Robert.

Hi Robert, Once you have the code working cleanly could you post the modified file to osg-submissions. ok, checking now.
