Embedding a tracker in an image to analyze pixel space

Pixeltracker.tox (11.7 KB)

This is a technique for observing change in Top color in a 3D space visual representation.

This technique can be used to understand Tops, or the difference between similar tops. You can also use it while developing your own GlSL tops

Think of it like a vector scope, but it does not analyze your image, rather it reflects the changes that have been made to the image in your workflow

All images begin with the same starting shape, a color balanced sphere in the center of a color space cube; with R,G,B,C,Y,M, Black, and white as the corners of the cube,(0-1)

Watch the Color space shift in or around the cube as you modify your TOP procedure, and use it as a visual aid to understand what it is a particular TOP is doing to your pixel space

In this example:

-Check out the difference in saturation when using HSV vs OCIO by bypassing one at a time

-Check out how hsv and level clamp the values by bypassing everything else

-When applying this technique to your workflow, substitute these colored nodes with your own procedural chain

note:Ensure all parts of the tracker have uniform pixel formats.
