Can a shader be used to detect collisions?

[neginfinity]

You can write data from shaders into RWStructuredBuffer and extract it. This has been introduced either in DirectX11 or DirectX10. But.

I’m quite certain you will not be able to do that in shadergraph. You’d need either a full code shader or you’d need to use function nodes.

In practice something like this has been used for voxelizing scene in NVida VXGI, for example.

Is shader graph support compute buffer ?

I want to use shader graph,but some data come from compute buffer. I often use instance render, custom compute buffer. Thanks in advance.

Compute shader Buffer/RWBuffer vs StructuredBuffer/RWStructuredBuffer

So does unity not support regular RWBuffer? I wrote a compute shader using Buffer type because i only need floats yet i get strange outputs. But it works fine for structured buffers but thats more for generics which i don’t need and is much slower than regular Buffer… Does unity simply not support regular Buffer type?

How to write to an unordered access compute buffer from a pixel shader?

Hello, I am trying to write a pixel shader that makes arbitrary writes into a RWStructuredBuffer<> ComputeBuffer. Writing to these buffers from the pixel shader should be supported according to MSDN, and is hinted at by the Unity docs. However, I cannot make it work. There are no errors, the buffer that I pass to GetData() simply fails to be filled with anything. I have tried both Material.SetBuffer() and Graphics.SetRandomWriteTarget(). My test is quite simple - I have a vertex shader that p…
