WebEdit: So, I've worked this out a bit, and would appreciate if somebody could verify that this would be the proper way to triple buffer my lights SSBO. Assume we split it into three buffers: A, B, and C. Display A, while drawing into B. In my case, I guess "drawing" would actually mean writing my updated light positions into the buffer. Web22 de fev. de 2024 · For example, you could create a regular grid spanning the bounding box of your mesh, and in each grid cell store a list of indices into the main data array for the elements that intersect that grid cell. The creation of this grid could be done in a compute shader earlier in the frame, and should be quite fast.

Web20 de out. de 2024 · In GLSL, you present much of the OpenGL state as pre-defined global variables. For example, with GLSL, you use the gl_Position variable to specify vertex position and the gl_FragColor variable to specify fragment color. In HLSL, you pass Direct3D state explicitly from the app code to the shader.
