Hello..
1)
I just plan to perform something like that:
Code:
osg::ref_ptr<osg::Shader> EarthLoQVert =
osgDB::readShaderFile(g_SceneGlobals.systemPath +
"media/programs/EarthLoQ.vert");
if(EarthLoQVert.isCompiledOK)
{
create1..........
}
else
{
osg::ref_ptr<osg::Shader> EarthLoQVertexLighting =
osgDB::readShaderFile(g_SceneGlobals.systemPath + "media/programs
/EarthLoQVL.vert");
if(EarthLoQVertexLighting.isCompiledOK)
{
create2
}
else
{
fatalError
}
}
i need to know if my shader is compiled ok after loading!
then i can create scene states, otherwise i load other shader and create other
scene states
thanks
2) Are shaders with same names loaded single time ?
Code:
osg::ref_ptr<osg::Shader> EarthLoQVert =
osgDB::readShaderFile(g_SceneGlobals.systemPath +
"media/programs/EarthLoQ.vert");
osg::ref_ptr<osg::Shader> EarthLoQVert1 =
osgDB::readShaderFile(g_SceneGlobals.systemPath +
"media/programs/EarthLoQ.vert");
osg::ref_ptr<osg::Shader> EarthLoQVert2 =
osgDB::readShaderFile(g_SceneGlobals.systemPath +
"media/programs/EarthLoQ.vert");
or should i check it self ?
3) Same question like "2" is for:
osg::ref_ptr<osg::Image> nrmlImage =
osgDB::readImageFile(g_SceneGlobals.systemPath +
"media/textures/earth/normalmap.bmp");
If there will be new questions - i will post that here...
thanks!
