1. BumpingSphereRender - render textured sphere with directional light and bump mapping.
2. LightTexturedSphereRender - render textured sphere with directional light.
3. TexturedCubeRender - render cube with texture.
4. TexturedQuadRender - render quad with texture, demonstrate how to apply 2D texture to the surface.
5. ColoredCubeRender - render multicolored cube, demonstrate how to use VAO with single VBO and IBO.
6. ColoredQuadRender - render multicolored quad, demonstrate how to use VAO with single VBO that contains multiple vertex attributes (positions and colors).
