assert(std::abs(determinant) > MACHINE_EPSILON)

Hey,

I'm innocently using ReactPhysics3D and am getting this assert raised... and not sure how to go around debugging it.

This is the stack trace if it helps.

Sorry, I think I missed this issue.

Do you still having some issues ? Can you share some code so that I can try to reproduce this issue ?

Hi there, in my opinion, that assertion just means that the determinant is zero (or too small), hence the matrix you calculated its determinant, is not invertible, which means that does not have a solution because one of the rows can be eliminated by substitution of another row in the matrix, i.e. some of the rows in the matrix is a linear combination of some other, they are not linearly dependent.

I am closing this issue. Feel free to reopen it if you have a code example that is failing with this error.
