Detailed Description

Describes the properties needed to copy texture data from CPU to GPU.

This uploads one mip at a time.

It is the responsibility of the caller to:

  • ensure the destination textures is large enough to receive the data.
  • ensure the source buffer and destination texture are valid at the time the command is executed.
  • cpuSourceBuffer: Pointer to CPU source (ie. texels) to copy the data from.
  • bufferByteSize: Byte size (length) of cpuSourceBuffer.
  • destinationTexelOffset: The texel offset (width, height, depth) of where to upload the data. If the texture is a 2d_array the third element is the layer/slice.
  • mipLevel: Mip level to upload into.
  • gpuDestinationTexture: The GPU texture to upload the data into.
