…detection - Updated the condition to detect concave vertices: If the z component of the cross product is less than or equal to zero, the triangle is considered concave, indicating that the angle between the vectors is greater than 180 degrees. - Improved the condition to detect flat triangles: If the norm (length) of the cross product is close to zero, the vectors are collinear, making the triangle flat with no area. - Added detailed comments to explain the conditions for concave and flat triangles for better readability and maintainability.
