@xinjinmeng yeah. Hmmm. I doubt if current tools are designed to work beyond rectangles. And if you don’t go large enough with the resolution to make it explicit everything are, say, circles, you might wind up with fuzzy pixel art as originally dispalyed on CRTs. :/
I’m not in the space nearly enough but maybe there’s a more generic framework you can draw with? What engine/frameworks are you presently working with?
