@Azy Bodysoulspirit You have to think about what you're asking the computer to do ;)
A line strip object is a strip of lines, if the line width is small enough it will appear as a smooth circle. However, a line is also a rectangle. This means that if you increase the line width to a large size, gaps will appear as you essentially are drawing rectangles on the points on a circle.
To rectify this, you can draw triangles between the points of two circles instead:
To get a result like this:
(I sped through this, there may or may not be double the points needed in the final result)
I can only speak for my own nodes, but if you are on a M1 mac, they might not have been recompiled to support it. If you downloaded my nodes yesterday they should work in theory, but you might have to double-click the .vuonode to install them.
Oh, I'm answering before reading now it seems 😅. Then you want the "Mask Image by Brightness" node I think. Alternatively a custom shader that converts a luma range in the input image to alpha.
There aren't any examples in it yet, but it should get you going with the barebones needed to drop in an example file from the node examples by team Vuo, and add it to the CMakelists file for compilation.
I would actually rather recommend "The nature of code" by Daniel Schiffman found here: https://natureofcode.com/. This explains more the realm of graphics programming and concepts for creative coding. It is made for Processing, but as the Vuo API deals with most of the heavy C stuff for simpler nodes, it isn't too far off for making nodes if you can manage to translate for instance a vec3() to a VuoPoint3d().
