This SWF computes the rectangular bounding (aabb) of a circle arc segment. This is usefull to pretest object intersections in e.g. physics engines. Drag the anchors to modify the start- and endAngle of the circle segment.
This SWF computes the rectangular bounding (aabb) of a quadric beziercurve. This is usefull to pretest object intersections in e.g. physics engines.
This physics engine works with penetration detection of any object. If a penetration (intersection) is detected the simulation will run backwards and forwards in frame-time, untill a accurate collision time is found. After that, the last detected collision is resolved.
More features:
ConvexPolygons as Springmodels
Time-exact simulation resolve
Space-Subvision by grids
Revive is based on ‘Dynamic Intersection’, which provides very fast moving objects. The source includes some more scenes.
Some particles can move phreatic in space, where small distances between 2 particles create an attraction force. Interact with the mouse.
First attempt to build a pinball physics engine. This version works with dynamic intersection, but misses an accurate collision resolve with respect to time.
Just another view implementation of the physicss engine.
First attempt to resolve rigid bodies collisions.
A balls collides with a quadric bezier spline.
