Function:ns2spheret
From S2PLOT
ns2spheret
Draw a textured sphere, with given centre, radius, colour and texture filename.
Prototype
void ns2spheret(float x, float y, float z, float r, float red, float green, float blue, char *texturefn);
Description
Draw a textured sphere, with a given centre (x,y,z), radius (r) and RGB colour (red, green, blue). The texture file is specified by texturefn, and must be a .TGA file that has length and width as powers of 2. The utility program texturise.csh can be used to convert your textures to the appropriate format. This is an OpenGL restriction.
