Update:

The current plan is to add a high performance physics engine within Volts itself. Complete with gravity, collisions, and more.

Object3D.usePhysics()

usePhysics should take care of collision detection and response all on it's own. While being moderately fast.

The objective:

  • Add accurate real-world physics. Linear, accelerated, and parabolic trajectories
  • 100+ objects on scene at any given time

Tasks:

Read the old issue by clicking on the arrow. Note that this is no longer the objective Add a method that binds the current code base to other libraries such as Oimo.js, Cannon.js, or others.

Ideally physics would be its own separate script that can be loaded & bound as needed, in order to not have huge amounts of unused code; which adds to size and initial load times (I don't know the extent to which the latter is a significant issue)

This issue will probably stay on hold until:

The BoundingBox signal works properly

It doesn't yet... but with onNextTick and the Snapshot the values can be fetched

An impulse/ Matrix based solver would be a nice addition. Help needed.

  • A matrix class with
    • inverse
    • transpose
    • multiply-vector-by-matrix

would be of huge help

Update: all have been added, along with their tests

The size (SLOC) of the physics solver alone is making me consider splitting up volts into multiple files that later get packed. Downside would be modifying things across 'compiled' versions would be hard, making modifying things inside of Spark difficult

The SLOC size of the Verlet solver is quite small, but impulse, AABB, collision detection, etc all will be huge. Will need to consider how to structure it
