Function Documentation

R_FillArrayData()

void R_FillArrayData	(	mAliasModel_t *	mod,
		mAliasMesh_t *	mesh,
		float	backlerp,
		int	framenum,
		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

R_ModCalcUniqueNormalsAndTangents()

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
