Detailed Description

OpenGL primitive base class

Base class for all classes implemting OpenGL primtives. This class maintains 4 main arrays for controlling the appearance of the geometry generated: a coordinate set, a color set, a normal set and a texture coordinate set. OpenGL primitives are created indirectly from these by specifying indices with instances of CIvfIndex. A quad set is created using this principle in the following code:

        CIvfQuadSet* quadSet = new CIvfQuadSet();
        
        quadSet->addCoord(0.0,0.0,2.0);
        quadSet->addCoord(1.0,0.3,2.0);
        quadSet->addCoord(2.0,0.0,2.0);
        quadSet->addCoord(0.0,0.3,1.0);
        quadSet->addCoord(1.0,0.5,1.0);
        quadSet->addCoord(2.0,0.3,1.0);
        quadSet->addCoord(0.0,0.0,0.0);
        quadSet->addCoord(1.0,0.3,0.0);
        quadSet->addCoord(2.0,0.0,0.0);
 
        coordIdx = new CIvfIndex();
        coordIdx->add(0,1,4,3);
        coordIdx->add(1,2,5,4);
        coordIdx->add(3,4,7,6);
        coordIdx->add(4,5,8,7);

        quadSet->addCoordIndex(coordIdx);

        quadSet->setMaterial(greenMaterial);
        quadSet->setUseVertexNormals(false);
