Lets refactor the code for the scene buffer to use dynamic uniform descriptor and not hardcode the offsets. The first thing to do is to reserve some size for dynamic uniform descriptors in the descriptor pool. In init_descriptors(), change the descriptor sizes for creating the descriptor pool to this Dynamic uniform buffers are a … See more To know what is the minimum alignment size for buffers, we need to query it from the GPU. The limit we are looking for is called minUniformBufferOffsetAlignment. You can look at said … See more We will be adding some default parameters to the scene data. We will stick fog, ambient color, and a sunlight here. We won’t be using all of the data, it’s there as example data that you can use however you want. … See more We are going to copy the shader that we were using until now, colored_triangle.frag, and we will call it default_lit.frag, as we will be adding lighting to it. … See more WebAug 13, 2024 · With all of that set up, you can then copy your frame data to the uniform buffer like so: void* udata = nullptr; vkMapMemory(device, buffer.deviceMemory, 0, dynamicAlignment * PRIM_COUNT, 0, …

WebAug 2, 2011 · Uniform blocks were designed to ease the sharing of uniform data between programs. In this article by David Wolff, author of OpenGL 4.0 Shading Language Cookbook, we will create a buffer … Web8. I'm sort of struggling to understand the conceptual difference between uniform buffers and push constants. From what I can gather by reading the spec, the main differences are: Uniform buffers can be much larger than push constants. UBOs use std140, PCs use std430. UBOs can be updated at any time with vkCmdUpdateBuffer (or host mapping) … high ram usage when idle
