Ogre3d really deserves some attention to deliver its full potential. A good example is the management of different version of shaders in a single program. In the image here above, the graphical cards are very different: the laptop has a low-end integrated intel chipset, the workstation is working with a GTX 980. The supported opengl …

Several hours of work later, the class PMaterial is fully integrated to PNode. This part has been tricky: materials and textures are shared objects, managed by managers below the objects. The approach is to create PMaterial on demand, when you call pnode.getMaterial, for instance. Once created, it stays in the pnode until you destroy it …
