Operators are a category of textures that generate patterns as a result of a mathematical function. You can use these by themselves, or combine them with the Mapping and Color textures to create surface effects that are very memory-efficient compared to direct-loading bitmap images. These can also create Bump maps and other advanced materials with minimal impact to GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process. memory.
