Detailed Description

CUDA-memory based canvas.

Using a CUDA-memory based enables NVIDIA IndeX to run rendering and image compositing on the GPU only without ever transferring data from GPUs to main memory. NVIDIA IndeX support the creation of a built-in CUDA canvas that derives from the following interface class.

Member Function Documentation

get_cuda_canvas()

virtual mi::neuraylib::ICanvas_cuda * nv::index::IIndex_cuda_canvas::get_cuda_canvas ( ) const

pure virtual

Returns the CUDA memory based canvas for external use, e.g., by a video encoder as input.

Returns

The low-level CUDA memory canvas.

get_device_id()

virtual mi::Sint32 nv::index::IIndex_cuda_canvas::get_device_id ( ) const

pure virtual

The CUDA memory canvas is hosted on a CUDA device.

The CUDA device ID tells the user by which CUDA device the canvas is managed.

Returns

Returns the device ID.
