| 3 | * Definition of an MD2 Model, a model format invented by ID Software. |
---|
| 4 | |
---|
| 5 | We are deeply thankfull for all the wunderfull things id software made for us gamers! |
---|
| 6 | |
---|
| 7 | The md2 file format is structured in a very simple way: it contains animations which are made out of |
---|
| 8 | frames (so called keyframes). 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). |
---|
| 10 | |
---|
| 11 | A typical model has about 200 frames, the maximum frame count is fixed by MD2_MAX_FRAMES to currently |
---|
| 12 | 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 | |
---|
| 15 | Surface Culling is fully implemented in md2 models: quake2 uses front face culling. |
