=== Constant Table Entry ===
=== Constant Table Entry ===
Each executable's constants are stored as in constant uniform table. This information is used by ctrulib's SHDR framework to automatically send those values to the GPU when changing to a given program. An entry is constituted by a header and the constant data, the latter of which uses a format specific to the constant type.

Keep in mind that the usage of the term "Uniform" here is used as [https://developer.download.nvidia.com/CgTutorial/cg_tutorial_chapter03.html defined by Nvidia] (variable who obtains its initial value from an external environment) and not as defined by RenderMan/GLSL (variables whose values are constant over a shaded surface).
The uniform table contains a list of all registers whose initial values are derived by an external source.
