Is this possible with procedural textures code? Say the procedure is currently operating on pixel (1,2) but I want to know the red values of the pixels at (1,1) ánd (1,3) - how do I get that data? Is there any sort of array structure I can use to store and index a lot of different values? Can I directly access the pixel data of the image as an array? Also is there a way of shifting the entire image or perhaps the current row/column by n pixels procedurally (like "affine" but in code)? If not then please consider this a feature request.
I'd like to make some suggestions for making the creation and use of the procedural texture filter a lot easier. Allow the formula to be created in a text area, not just a single line. Making this area collapsible would be great so you could hide it if desired Instead of having to use the RGBA buttons to target a channel, just make those global variables. Then from any equation, if you set R = some value, it would affect the red channel. Documentation There really needs to be more documentation. Not just a list of functions but what those functions d
