Proper way to handle origin/coordinates mismatch?

[eliasdaler]

Hello.

When in my engine, the origin of all objects is usually located at the bottom of the model. When I create and position the shape, the center of this shape is mismatched (obviously):

Is using RotatedTranslatedShape the right way to handle this mismatch?

Basically, I do this:

shape = new JPH::CylinderShape(2.6f, 1.8f);
shape = new JPH::RotatedTranslatedShape({0.f, 2.6f, 0.f}, JPH::Quat().sIdentity(), shape);

When I do this, the shape works as expected and Jolt's and my engine's positions match 1 to 1.

So, I was wondering - should I apply these offsets to each mesh/shape which needs it or is there some other way to handle this?

Yes it is

I see, thanks!

So, to check that I understand correctly: moving using RotatedTranslatedShape just moves the "origin" around which GetPosition, GetCenterOffMassPosition etc. report will report their values, but it doesn't change anything else about the simulation/shape itself, right?

Yes, it doesn't change the simulation

I see, thanks again!
