Notes

Some notes, considerations and improvements.

PolyPoint Head

Perhaps an import head to store all functions

Poly.Point
Poly.functions.saveRestoreDraw
Poly.math.PI_2

• offcanvas rendering

• threads and processes for off-canvas loops.

• auto concat the polypoint

• Consider if functional hash map chains is faster than functional calls
• Event central

Generally polypoints should move towards an actor <> runtime engine, where all Stage integrations perform actor operations on a stage runtime, rather than the current, point-centric methodology.

This will provide better resource management, and coupled values.

• variable numbers. Couple a percent with some number to compute dynamic variables:

// 40% from top-left.
point.x = var("40%", stage.point)

• Natural elements some elements can be applied to a point. The values may be lazy.

  • Velocity
  • Pens and drawing
  • siblings parent, child previous, next

  A point should be able to relatively move from its origin, such as wobbling on a point, using the original location as a reference. + forced at and from Allow the impart of forces, including torque and velocity.
