Frequently Asked Questions
How does the circle algorithm work?
The tool uses the midpoint circle algorithm (Bresenham's) to calculate which blocks should be placed to best approximate a circle on a block grid.
What is the difference between filled and hollow?
A filled circle fills all blocks inside the circle. A hollow circle only shows the outline, with adjustable wall thickness.
What is the maximum radius?
You can generate circles with a radius from 1 to 128 blocks, covering most Minecraft building needs.
