ns2vspheret
Draw a textured sphere, with given centre, radius, colour and texture filename - vector input.
Prototype
void ns2vspheret(XZY P, float r, COLOUR col, char *texturefn);
Description
Draw a textured sphere, with a given centre (P), radius (r) and colour (col), using vector data structures. 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.

int main(int argc, char *argv[])

s2opend("/?",argc, argv); /* Open the display */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
