Nuke implementation for 2D Gradients.
Create an arbitrary number of color-samples in 2D, which will produce a smooth, natural interpolation over the entire image.
The Gizmo uses Natural Neigbor Interpolation to calculate the pixels inbetween samples, using Blinkscripts.
You can also output the underlying Voronoi Diagram.
Another important function is the ability to sample input colors, instead of defining them yourself. Setting the Type to 'Sample' used all created points to sample the input colors at given positions.
Changing the Colorspace will change the color falloff. This can be used to achieve the best artistic result.
There are several tricks used in this Gizmo to make it work, one being a method to feed an arbitrary number of input parameters into a Blinkscript. All types of Nuke scripting are going on here, like Python, TCL, Expressions and Blinkscripts. Please report any bugs you find, I am sure there still are some. The user knobs and the inside of the gizmo are well documented to help with understanding the concept.
Animation on the Position and Color knobs is not supported. I might redo the gizmo as C++ plugin in the future to solve this isse and to introduce a gap-filling method, that assumes every given pixel as sample and fills in holes that are defined by a black alpha.
Using the Sample Type to generate a cleanplate:
Update to 1.1
- Fixed the string separator declarations for some Expressions from ',' to ,
Update to 1.2
- Fixed another Expression I forgot in 1.1
