Hi all,I have been porting some shaders from GLSL. Now I have a function where I have to calculate a modulo and get a floor for the numbers.In GLSL there are mod() and floor() methods.Anybody tried to “improvise ” with this kind of calculations in AGAL?
Anybody succeded to find a substitute for mod() and floor() in AGAL ?Software: Away3D 4.x |

To calculate a mod b, you could divide a by b, take the fractional part of the result, and multiply that by b. [a mod b = (frc (a / b)) * b] |
