Project Notes

drag the vertices to move them.

press space to draw the inscribed circle of a triangle.

completely done with math. extremely fast.

Inspired by ssaamm's idea for filling a triangle:
"I believe the most efficient way to do this is to make concentric lines from the outside, slowly getting thicker and thicker as it comes toward the center."

this has been used now for creating a large circle which can take up a lot of the area of the triangle.
