In Microsoft Direct3D, anything that uses memory is considered a resource: textures, vertex buffers, index buffers, render targets, constant buffers, structured buffers, and so on. It��s natural to think that each individual object, such as a texture, is always one resource. In this post, I discuss DXR��s Bottom Level Acceleration Structures (BLASes) and best practices with regard to managing them.
