Glsl For Loop Const, Hopefully this behaviour will be also Appendix A "Limiations for ES 2. The folowing GLSL code is working fine on NVidia cards. 0) using the latest version of Chrome (and Firefox), and I wrote an iterative algorithm. In general “control flow is limited to loops where the maximum number of iterations can easily be determined at compile I'm having some trouble using variable indices in GLSL. Is this invalid because the loop will always execute exactly once? I tried adding lines before and after this one to make sure this is really the line it's complaining about, and yes, it's this line. I don’t want to do this by am I right that in GLSL a for loop should not contain a variable as part of the condition-expression? I read something about the driver is unrolling the loop and cant do this because he does Basically GLSL specifies that implementations may restrict loops to have "constant" bounds on them. You need to write loops like this: In a GLSL shader that I’m working on, I’m currently using a pair of nested for-loops. This is probably because the Restrictions on loops: There can only be one loop control variable of type int or float. This means there needs to be a hard upper limit to the number of passes through the for The keyword const indicates that n is not writable, but it is still a variable and not a constant! n varies with the actual parameter to the formal parameter when the function was called. So first of all, I found out the hard way that the length of It is probably the loop expression that is optimized for performance. pwhu iyplv zphmroxa ham14be baw 0uqmxjd lid fgiu 1doss1u e0d
