Features

• Written in Haxe
• Exported as JavaScript (see bin/js/) Public classes and methods will be exposed through windwow.OIMO. e.g. new OIMO.Vec3(1, 2, 3) to create an instance of Vec3 class.
• Rigid body motion types Dynamic Static * Kinematic
• Fast collision detection with bounding volume hierarchy (BVH)
• Contacts with friction and restitution
• Collision geometries Sphere Box Cylinder Cone Capsule Convex hull
• Joints with springs, limits and motors Spherical (a.k.a. ball and socket, point to point) Revolute (a.k.a. hinge) Cylindrical Prismatic (a.k.a. slider) Universal Ragdoll (a.k.a. cone twist, character)
• Breakable joints
• Constraint solvers Direct block MLCP solver Projected Gauss-Seidel solver
• Sleepings with island splittings
• Rotation limits
• Collision event callbacks
• Collision filterings
• Collision queries AABB query ray casting * convex casting

Compile JavaScript demos in Haxe

• Use Haxe 4.0.0 or later
• main class: demo.js.DemoJS
• Try enabling compiler options if fails -D analyzer -D eval-stack
