Vocabularygpu.buffersClass descriptionbuffer-usage-pattern values aid the graphics driver in optimizing access to
buffer objects by declaring the primary provider and consumer of data for the buffer.
| • | draw-usage declares that the buffer will be supplied with data from CPU memory and read from by the GPU for vertex or texture image data. |
| • | read-usage declares that the buffer will be supplied with data from other GPU resources and read from primarily by the CPU. |
| • | copy-usage declares that the buffer will both receive and supply data primarily for other GPU resources. |
A
buffer-usage-pattern is only a declaration and does not actually control access to the underlying buffer data.
