Glsl smoothstep performance
WebNov 29, 2024 · Instead of that I also often use the smoothstep function since it’s a built-in function, but that one also does some smoothing we don’t need here, so it’s less effective overall. ... We can’t change the performance demands of the functions but I’d also argue that in 99.9% of all cases your performance bottleneck won’t be here, as ... WebShader Minifier. Shader Minifier is a tool that minifies and obfuscates shader code (GLSL and HLSL) without affecting its behaviour. It is also suitable for reducing the size of the shaders in other applications (e.g. …

WebJan 10, 2024 · The GLSL spec is very lazy in terms of compulsory behaviors, but I observed that the worst is often when relying to early evaluation of functions (i.e. all const parameters), e.g. in term of IEEE754 compliance, behavior for swapped parameters, etc. Note also that despite some out-of-spec situations often work correctly ( i.e. as expected … WebJust like GLSL ES 3.0, implicit casting between scalars and vectors of the same size but different type is not allowed. Casting of types of different size is also not allowed. Conversion must be done explicitly via constructors. Example: float a = 2; // valid float a = 2.0; // valid float a = float(2); // valid.
