Yes that fixed it. I did also try an arbitrary modulus with WebGL and that worked fine. I'm not sure why so much documentation seems to indicate that % is not allowed in GLSL at all? If it's okay, can I just change this pull request to implement the suggested name change. |
Sounds great! |
Ok cool, I'll also make sure there's a deprecation option per the new standards. |

There was a problem hiding this comment.
I think could be good add what release it was deprecated
export const remainder = ( ...params ) => { // @deprecated, r168

remainder() to modInt().
Description
Between WGSL and GLSL, there are differences in how the commonly used modulus operation is handled. GLSL has a function mod() that computes x modulo y. It does not permit the use of the % operator to perform the same operation. Meanwhile, WGSL does allows the use of the % operator to compute the modulus of two numbers, and therefore has no equivalent function mod. Therefore, when the % operator is used in a TSL shader via the remainder() function, that shader will be valid for the renderer's WebGPUBackend, but invalid for its WebGLBackend. While a user could simply write their shader to use remainder or mod depending on what graphics API they are targeting, this solution negates the inherent portability of TSL shaders across shader languages.Modified to simply rename remainder and mod to make their usage more clear.
