I'm a comfortable java programmer and am learning basic OpenGL, looking at sites like this. I've completed a few basic tutorials. AFter surfing the web on OpenGL I'm trying to set out my limits. I can see how 3-d cubes would be modelled but how would I go about modelling something like a cat and have it look realistic. Would I start with polygons and add texture later? Would this look trashy? Please advise your input would be of much much value.
