WebAug 10, 2016 · I see a lot of shader code on the internet where PI is simply defined as an approximate decimal near the top of the code. In general I try to let computers take care of doing math for me instead of approximating values with constants (i.e. (1./3.) instead of 0.333). Pi seems like one of those things that would be easier to just use intrinsic … WebApr 28, 2013 · GLSL is not C, where you could expect the performance of a particular function to be invariant with other changes. In shader compilation, functions will be inlined, instructions will be statically reordered to hide latencies for various operations, and so forth. ...

WebIt is reasonable to assume that dot product operations, despite the complexity of them, will be fast operations (possibly single-cycle). Given that knowledge, the following code can be optimized: vec3 fvalue1 ; result1 = fvalue1 . x + fvalue1 . y + fvalue1 . z ; vec4 fvalue2 ; result2 = fvalue2 . x + fvalue2 . y + fvalue2 . z + fvalue2 . w ; WebMar 10, 2015 · Find Cycles Nodes a little confusing?
