ptk::Colormap::Texture Class Reference

Detailed Description

The Texture class is used to store and track the actual data, as well as ensure it is loaded to the GPU, while the Colormap wrapper is used as a shared copy-on-write pointer to a Texture that allows us to have built-in Colormaps (such as HEAT) which the user can "modify" without disturbing other users of that colormap. But, if the user isn't modifying it, this allows us to only have one copy in memory instead of dozens.
