Matrix not invertible
Posted: 26 Jul 2024, 19:32
Dear all,
we're using Noesis in our quite big Unity project and had exceptions with non invertible matrices.
We needed to change those lines

Our map needs to invert some close to singular matrices... We're doing matrix transforms from long/lat (world positions) in meters to screen space, which obviously have very large numbers. Works fine, could be change of course.
Is that a change you would see as potentially dangerous?

Code: Select all
public bool HasInverse {
get { return Math.Abs(Determinant) >= 0.0001f; }
}
public void Invert() {
float determinant = Determinant;
if (Math.Abs(determinant) < 0.0001f) {
throw new InvalidOperationException("Matrix is not Invertible");
}

public bool HasInverse {
get { return Math.Abs(Determinant) >= float.Epsilon; }

if (Math.Abs(determinant) < float.Epsilon) {
throw new InvalidOperationException("Matrix is not Invertible");
