Does anyone have any idea how may I calculate vectors normal for lighting for thoes models?

Take the Cross Product of 2 vectors on the triangle and then normalize the result it. The normal direction depends on what order the vectors are in relation to the triangle(clockwise or counter-clockwise).

Here''s a link for vector :

...
Shouldn''t exist a ''table of normals'' indicized by a field of the vertex structure of the md2 file?
I used to think so...

OK We misunderstood eachother. MD2 are optimalized for GL_TRIANGLE_STRIP or GL_TRIANGLE_FAN, and they don''t have a direct table of vertices and triangles. But I have already founded a solution for it in Cone3D Tut. 4
