WGPU part 4: Buffers and Bind Groups

Support the channel here: https://www.patreon.com/cw/TimidAutomaton Find the example code here: https://github.com/TimidAutomaton/WGPUExamples/tree/main This video is a quick explanation of buffers and bindgroups in WGPU. We explain vertex, uniform, and storage buffers and how they are passed to the GPU. This is the majority of the information you need to know to communicate data between your CPU programs and GPU programs. We’ll talk about textures next time, but this gives you the basic idea of how they will be implemented as well.
