A variation of yesterday’s sketch, the class example for Object Orientation with “particles”, but now using Py5Vectors.
sketch_2022_11_11
Sketch made during the Object Orientation class at BA.

A preliminar attempt using window.read(timout=20) has to be tested. There is a version using a launch_repeating_thread() in the same sketch folder.

56 triangles, all 3 point combinations from 8 vertices of octagons.
sketch_2022_11_08
I’m not sure I like it but… this demonstrates a P2D renderer feature that allows to change the stroke (and also fill in case of closed shapes) for each vertex.
sketch_2022_11_07
378 pairs of line segments, all the combinations from 8 points arranged as an octagon.

Frank Morley’s theorem demo
«In 1899, Frank Morley proved Morley’s theorem: when the angle at each vertex of any triangle is trisected, the points of intersection of adjacent trisectors form the vertices of an equilateral triangle» @fermatslibrary’s tweet

- Added naïve poly simplification
- I’m happier with (newest) “gradual flip”
- I gained some insight on why everything is worse with different radius for each vertex (and it is hard to fix).
- I changed the radius reduction behavior!
sketch_2022_06_12
- arc_augmented_points() (to complement arc_augmented_poly)
