Dear all, I'm trying to figure out how to tile arbitrary 3D textures. I would have thought a weighted average as shown below would work: double f=( (F(x,y,z)*(5-x)*(5-y)*(5-z))+ (F(x,y,z-5)*(5-x)*(5-y)*(z))+ (F(x-5,y,z)*(x)*(5-y)*(5-z))+ (F(x-5,y,z-5)*(x)*(5-y)*(z))+ (F(x-5,y-5,z)*(x)*(y)*(5-z))+ (F(x-5,y-5,z-5)*(x)*(y)*(z))+ (F(x,y-5,z)*(5-x)*(y)*(5-z))+ (F(x,y-5,z-5)*(5-x)*(y)*(z)) )/(5*5*5); But this doesnt seem to work. If anyone has any ideas on how to do this I'd apprciate it. Regards, Jesse
