Functions

void derr (char *when, char *where=0)

glift::SingleTex * loadNrrdTexture (char *nrrdTexName, int texType)

Load a single nrrd texture Check for zero on return value for failure to load.

glift::SingleTexSP loadNrroTexture (const NrroSP n, int texType)

int getSimtType (const NrroSP n, int texType)

glift::SingleTexSP loadTexture3D (float *data, int sx, int sy, int sz, int comp, int texType)

Load Texture, explicit, standard texture object state: Linear, clamp to boarder (if applicable) or clamp BEST FITS: Comps Type General Type nv123x Type ATI 9700+ 1 Lumanance HILO16 Fixed16 Lum 2 Lumanance Alpha HILO16 Fixed16 Lum Alpha 3 RGB8 RGB8 RGB16 (FIXED) 4 RGBA8 RGBA8 RGBA16 (FIXED).

glift::SingleTexSP loadTexture3D (char *data, int sx, int sy, int sz, int comp, int texType)

glift::SingleTex * loadTexture1D (float *data, int sx, int comp, int texType)

glift::SingleTex * loadTexture2D (float *data, int sx, int sy, int comp, int texType)

GLenum getInternalFormat (int nComps, int simtType)

find the best fit texture type, returns the higest precision (best == interpolating) type for the current platform and the number of components requested this function is mostly for internal use, SIMT_BEST is "best"

GLenum getExternalFormat (int nComps, GLenum inFormat)

Get the gl texture format for the reqested number of components you can pass in the internal format if that effects the type of the external format, as it does on NVidia cards, (HILO).

try to identify the platform type this is a fucking hack, fix it, there must be a better way
