Abstract
A technique for optimizing the rendering of such complex render-graphs caches intermediate buffers of nodes that are expected to be re-used after they've been rendered. The render-graph is examined to determine the number of re-uses of each node's output buffer, and the buffer is cached in memory until all the re-uses of the buffer have occurred. Once all the re-uses of the buffer have occurred, the buffer is removed from the cache. This technique guarantees that for a given render-graph, no nodes will be re-rendered, resulting in improved render performance.
