		int	oldframenum,
		bool	prerender
	)

Converts the model data into the opengl arrays.

Parameters

mod	The model to convert
mesh	The particular mesh of the model to convert
backlerp	The linear back interpolation when loading the data
framenum	The frame number of the mesh to load (if animated)
oldframenum	The old frame number (used to interpolate)
prerender	If this is true, all data is filled to the arrays. If false, then e.g. the normals are only filled to the arrays if the lighting is activated.

Note

If GLSL programs are enabled, the actual interpolation will be done on the GPU, but this function is still needed to fill the GL arrays for the keyframes

Todo:

damn slow - optimize this

static void R_ModCalcNormalsAndTangents ( mAliasMesh_t *  mesh, int  framenum, const vec3_t  translate, bool  backlerp  )

static

Calculates a per-vertex tangentspace basis and stores it in GL arrays attached to the mesh.

Parameters

mesh	The mesh to calculate normals for
framenum	The animation frame to calculate normals for
translate	The frame translation for the given animation frame
backlerp	Whether to store the results in the GL arrays for the previous keyframe or the next keyframe

void R_ModCalcUniqueNormalsAndTangents	(	mAliasMesh_t *	mesh,
		int	nFrames,
		float	smoothness
	)

Calculates normals and tangents for all frames and does vertex merging based on smoothness.

Parameters

mesh	The mesh to calculate normals for
nFrames	How many frames the mesh has
smoothness	How aggressively should normals be smoothed; value is compared with dotproduct of vectors to decide if they should be merged
