Therefore, you should always ensure your shader has well-defined behavior on platforms that offer less support, rather than only on DX11. Cross-platform best practicesĭirectX 11 (DX11) supports many actions that are not supported on other platforms (such as Metal or OpenGL ES). However, there are some factors that need to be considered when doing this. Therefore, for the easiest cross-platform builds, you should write compute shaders in HLSL. Cross-platform supportĪs with regular shaders, Unity is capable of translating compute shaders from HLSL to other shader languages. For example, SamplerState MyLinearClampSampler creates a sampler that has Linear filter mode and Clamp wrap mode.įor more information, see documentation on Sampler States.

For this, the name has to have Linear or Point (for filter mode) and Clamp or Repeat (for wrap mode). In this case, the sampler is initialized to that Texture’s filter/wrap/aniso settings. Use the same name as the Texture name, with sampler at the beginning (for example, Texture2D MyTex SamplerState samplerMyTex). Textures and samplers aren’t separate objects in Unity, so to use them in compute shaders you must follow one of the following Unity-specific rules: See RenderTexture.enableRandomWrite to learn more about this. More info See in Glossary can also be written into from compute shaders, if they have “random access” flag set (“unordered access view” in DX11). Then you can use the Render Texture in a Material just like a regular Texture. To use them, first create a new Render Texture and designate one of your Cameras to render into it. Render Textures A special type of Texture that is created and updated at runtime. See Unity documentation on ComputeShader class for more details.Ĭlosely related to compute shaders is a ComputeBuffer class, which defines arbitrary data buffer (“structured buffer” in DX11 lingo). This allows you to invoke them with ComputeShader.Dispatch function. In your script, define a variable of ComputeShader type and assign a reference to the Asset.

The #pragma kernel line can optionally be followed by a number of preprocessor macros to define while compiling that kernel, for example: #pragma kernel KernelOne SOME_DEFINE DEFINE_WITH_VALUE=1337 When using multiple #pragma kernel lines, note that comments of the style // text are not permitted on the same line as the #pragma kernel directives, and cause compilation errors if used. There can be more kernels in the file just add multiple #pragma kernel lines. One compute shader Asset file must contain at least one compute kernel that can be invoked, and that function is indicated by the #pragma directive. The language is standard DX11 HLSL, with an additional #pragma kernel FillWithRed directive. Void FillWithRed (uint3 dtid : SV_DispatchThreadID) Here’s a basic example of a compute shader file, which fills the output texture with red: // pute They are written in DirectX 11 style HLSL language, with a minimal number of #pragma compilation directives to indicate which functions to compile as compute shader kernels. Similar to regular shaders, compute shaders are Asset files in your project, with a.
