Data Types Overview

In vkdispatch, there are a number of different datatypes that can be used to store data in buffers and images and to process data in shaders. These data types come in 3 formats (for now, all 32 bit):

In the near future 64 bit and 16 bit types will be added.

They also come in the following shapes:

  • Scalars

  • Complex Number (internally represented as vec2 in GLSL shaders)

  • Vectors (of size 2, 3, and 4)

  • Matricies (only vkdispatch.float32 at 2x2 and 4x4)
