Drawing function in Flowgorithm limited?

94 Views Asked by AFvS At 15 September 2023 at 12:03

My colleagues and I try to create the example image. In Small Basic code it works perfectly. But when created with Flowgorithm the beginning of the image starts progressively disappering while drawing the rest of the image after approx. 25% is done. Is there a memory problem or a max. number of pixels to be drawn? Settings maybe ?

I can confirm the defect/behavior. You can have at most 8000 operations, counting both draws and turns. Unfortunately it's not obvious to pin down. It's not the number of drawing operations alone. It seems that consecutive draw or turn operations get concatenated to reduce the total.

To test it, I tried to have a drawing with easily countable steps:

The following program shows that you can have at most 8000 operations, counting both draws and turns:
