storage image
An image that shaders can both read from and write to directly, like a 2D array in memory.
Ordinary textures are usually read-only and go through filtering hardware. A storage image instead exposes an image as raw addressable pixels a shader can freely load and store, at exact coordinates with no filtering. This is essential for compute-style GPU work that produces or edits images in place.
