Question by sjhalayka · Aug 02, 2019 at 04:01 PM · camerashaders

Is there any way to do GPGPU with Unity?

Is there any way to do GPGPU in Unity? What I mean is: is there a way to do an orthographic camera that renders to texture? If so, how does one do it?

Thanks for your time and patience.

Ok, don't tell me that you did a single search before asking this question.

Just to list a few results:

  • GPU General Purpose Computing with Unity Compute Shaders

  • Physics simulation on GPU with compute shader in Unity3D

  • Compute Shaders

  • Getting Started with Compute Shaders in Unity

Apart from using compute shaders, of course you can also just render to a texture. Also a quick search should have brought you:

  • Render Textures

  • Graphics.Blit

  • NativePluginInterface

  • Low level native rendering plugins

Even Nvidia who brought us CUDA has a specific article and assets for the use in Unity. All those are the first search results when searching for the most obvious combinations of terms like GPGPU or CUDA with Unity.
