Each frame is a complete draweable model in a specific position. 9 A frame is a collection of vertex and its compagnions (normals, texture coordinates). 11 #include <string> 10 12 11 A typical model has about 200 frames, the maximum frame count is fixed by MD2_MAX_FRAMES to currently12 512 frames. The maximal vetices count is set to 2048 verteces, not enough?13 You just have to change the MD2_MAX_* values if it doesn't fit your purposes...14 13 15 Surface Culling is fully implemented in md2 models: quake2 uses front face culling. 16 */ 14 class MD3BoneFrame; 15 class MD3Mesh; 17 16 18 #ifndef _MD2MODEL_H19 #define _MD2MODEL_H20 17 21 #include "base_object.h" 18 class MD3Model 19 { 22 20 23 #include "model.h" 24 #include "material.h" 21 public: 22 MD3Model(); 23 ~MD3Model(); 25 24 26 //!
