ns2cvra
Render volume of objects.
Prototype
int ns2cvra(float ***grid,
int adim, int bdim, int cdim,
int a1, int a2, int b1, int b2, int c1, int c2,
float *tr, char trans,
float datamin, float datamax,
float(*ialphafn)(float*));
Description
Volume rendering object, but with a function for alpha rather than a linear ramp. The ialphafn is called with a float (ptr) argument being the data value (which can be outside the (datamin, datamax) range of course) and should return a value between 0 (transparent) and 1 (opaque).
