Glsl fract function
WebIt occurs to me that you could use a simple integer hash function and insert the result into a float's mantissa. IIRC the GLSL spec guarantees 32-bit … WebApr 16, 2024 · The syntax of GLSL is very similar to C (and therefore to C++ and Java); however, there are built-in data types and functions for floating-point vectors and matrices, which are specific to GLSL. ... There are more built-in functions, which also work component-wise but are less useful for vectors, e.g., abs, sign, floor, ceil, fract, mod, …

WebThere are two forms of the index which can be selected by clicking at the top of the navigation bar on the left side: a traditional flat index combining the API commands and GLSL functions, and an accordion-style index with separate sections for commands and functions. The flat index also includes per-letter section links. WebNov 13, 2024 · AddySm. I am in the process of translating a few shader functions (for periodic simplex noise) written for WebGL to HLSL. The relevant portions of the code (original and translation) are below, for the output above I just used a dummy shader program with the equivalent of `fragmentw = psnoise (float2 (input.uv.x * 6, input.uv.y * …
WebAug 9, 2011 · This corresponds to the number of lattice rectangles per unit (scaled) texture coordinate. We then compute the fractional part of each component of the scaled texture coordinate using the built-in function fract. Each component is compared to 0.2 using the built-in function greaterThan, and the result is stored in the bool vector toDiscard. WebName. mod — compute value of one parameter modulo another.

WebWebGL - no matching overloaded function found. I have this WebGL fragment shader on my html file which is running fine, except when I call the first 5 vec2 functions. vec2 subCalc (vec2 z1, vec2 z2) { return vec2 ( (z1.x - z2.x), (z1.y - z2.x)); } It's weird because I use the vec4's, for example 'HSVtoRGB', the code runs fine.
