cuda.bindings._v2.driver.graphics_gl_register_buffer#

cuda.bindings._v2.driver.graphics_gl_register_buffer( GLuint buffer, unsigned int flags, ) → intptr_t#

Registers an OpenGL buffer object.

Registers the buffer object specified by buffer for access by CUDA. A handle to the registered object is returned as p_cuda_resource. The register flags flags specify the intended usage, as follows:.

CU_GRAPHICS_REGISTER_FLAGS_NONE: Specifies no hints about how this resource will be used. It is therefore assumed that this resource will be read from and written to by CUDA. This is the default value.
CU_GRAPHICS_REGISTER_FLAGS_READ_ONLY: Specifies that CUDA will not write to this resource.
CU_GRAPHICS_REGISTER_FLAGS_WRITE_DISCARD: Specifies that CUDA will not read from this resource and will write over the entire contents of the resource, so none of the data previously stored in the resource will be preserved.

Parameters:

buffer (GLuint) – name of buffer object to be registered.
flags (unsigned int) – Register flags.

Returns:

Pointer to the returned object handle.

Return type:

intptr_t
