Opencl types
Web17 de mai. de 2011 · These types aren't a part of standard C++. They might either be defined in some third-party library, or you're looking at some other dialect or language. GPU code (Shader languages such as GLSL, Cg or HLSL, or GPGPU stuff like CUDA or OpenCL) typically defines types like these though, as names for the corresponding … http://lukeo.cs.illinois.edu/files/2024_SpBiMoOlRe_tausch.pdf

Each fundamental opencl type has a vector version. You can use the vector type by appending the number of desired components after the type. Supported number of components are 2,3,4,8 and 16. OpenCL 1.0 does not offer three components. You can initialize any vector using two ways: Provide a single scalar; Satisfy all components
