WebApr 9, 2024 · Now both textures are distinguished via last attrib pointer, one float 0.0f for first texture, 1.0f for second one (and are converted to int to be used as index inside shader). But in the output, only the first one, namely the logo.png (as it is set first via Bind2DTexture (0, logo_id); will be drawn, whereas chessboard.png will not. WebUsing vec3 seems ideal because it would theoretically save a lot of memory. But perhaps that temporary vec4 (position,1.0f); costs some runtime performance at the savings of memory. I'd imagine creating a vec4 from a vec3 attribute would be a small cost, but was curious if anyone had thoughts. 10. 12.

WebAug 10, 2024 · Passing Float32Array and dynamic JS arrays is supported. I think the exact length of the array is what specifies the type of the array (e.g. if it’s a float[] or vec2/vec3/vec4[] @mvaligursky I would be glad if you can verify this). All arrays should be flattened, both Float32Array or regular dynamic arrays.
