Member Enumeration Documentation

enum gpuip::Buffer::CopyOperation

Operation when copying memory between CPU and GPU

Enumerator:

COPY_TO_GPU	Copy data from CPU to GPU
COPY_FROM_GPU	Copy data from GPU to CPU

enum gpuip::Buffer::Type

Supported data types.

Enumerator:

UNSIGNED_BYTE	8 bits per channel. Used in png, jpeg, tga, tiff formats
HALF	16 bits per channel. Used in exr images.
FLOAT	32 bits per channel. Used in exr images, typically when half is not supported in the current environemnt.

---

Field Documentation

unsigned int gpuip::Buffer::channels

Channels of data per pixel.

A typical RGBA image has 4 channels. Gpuip buffers with 2 or 3 channels have not been tested as much as 1 or 4 channel buffers.

const std::string gpuip::Buffer::name

Unique identifying name.

Each buffer has a unique name. The buffer can still be called referenced as something else in a kernel.
