Represents a server-side graphics memory region for sampling static images.
See also: ScinImageBuffer VTexPos VTextureSize
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
Class Methods
VSampler.fr(image, pos)
VSampler.sr(image, pos)
VSampler.pr(image, pos)
Make a VSampler VGen at the requested rate.
Arguments
image
The ScinImageBuffer object to sample or a server-issued image ID integer.
pos
A 2D vector to sample the input image at using the provided filter mode.
Returns:
The sampled color value of image at pos.
