CRW at a glance
CRW
Early Canon digital-camera workflows used raw formats like CRW before the later EOS raw families stabilized around CR2 and then CR3.
UV Map at a glance
UV Map
UV mapping became foundational once 3D graphics pipelines standardized on the idea of flattening mesh surfaces into 2D texture space for painting, baking, and material assignment.
