Re: inertia vector from inertia tensor matrix

Matrix of inertia represents how much torque is needed to make body get certain angular acceleration. In coordinates, which origin start in a center of mass the matrix is diagonal, meaning that providing torque at the origin in X axis ur will not make a body start spinning around Y or Z axes. If you...

Re: inertia vector from inertia tensor matrix

As you can see, the matrix is diagonal (which is good in local body coords). The most foolproof method would be to just create new vector like:

Code: Select all

btVector3 your_new_vector(matrix.m11, matrix.m22, matrix.m33)

Setting up bullet physics multithreading

Hello, I have the following problem - im trying to set up multi-threaded calculations in BP, however, not all seems to be going as it should. Here's the init code: static CustomTaskScheduler TaskScheduler(TEXT("bullet physics task scheduler"), PhysicsThreadCount); TaskScheduler.setNumThrea...
