the command zig run my_code.zig
will compile and immediately run your Zig
program. Each of these cells contains a zig program that you can try to run
(some of them contain compile-time errors that you can comment out to play
with)
In shader programming, you often run into a problem where you want to iterate an array in memory over all pixels in a compute shader | |
group (tile). Tiled deferred lighting is the most common case. 8x8 tile loops over a light list culled for that tile. | |
Simplified HLSL code looks like this: | |
Buffer<float4> lightDatas; | |
Texture2D<uint2> lightStartCounts; | |
RWTexture2D<float4> output; | |
[numthreads(8, 8, 1)] |
