Set of data, the amount of invocations has to be explicitly specified.Ĭompute shader invocations are divided up in batches called work groups, which However, since compute shaders can operate on an arbitrary Normally, a regular shader is executed on a predetermined set of data (such asĪn amount of vertices or pixels), in which case the amount of shader invocations In particular, image accessĬoncurrency, shared or coherent variables, and memory barriers are not covered It is by no means a comprehensive manualĬovering everything about compute shaders. This page only aims to give a cursory overview of compute shaders where it is Results can be achieved with render-to-texture processes. Using them certainly requires aĬertain amount of expertise with graphics programming. Unexplainable results, including garbled texture data, or even video cardĬrashes and system freezes in some cases. This means that it is very easy to get strange and It is important to know that compute shaders are an advanced, low-level, and

( dispatched) in a standalone fashion and perform an operation on an arbitrary They are fundamentally different from other types of shaders in that they aren’tĪssigned to a node and modify how the node is rendered, but are executed That can be used to perform a wide variety of functions on the video card. Compute shaders, introduced in 1.9, are a type of general-purpose shader program
