Extension
ExtensionRepresents a server-side graphics memory region for sampling static images.
Description
VSampler is the fundamental image sampling VGen in Scintillator. It takes a ScinImageBuffer id and a position as inputs and produces a VVec4 color output in (red, green, blue, alpha) order. VSamplers can be configured to sample the image buffer in a variety of ways which are documented below.
Supported Rates: frame, shape, pixel
