Vladimír Vondruš	a49bb0d718	Math: convenience functions for transforming vectors with matrices. It's now possible to conveniently transform 2D vectors and points with 3x3 matrices and 3D vectors/points with 4x4 matrices. Previous most low-level solution: Matrix4 m; Vector3 v; Vector3 a = (mVector4(v, 1.0f)).xyz(); Vector4 b = (mVector4(v, 0.0f)).xyz(); Another, more generalized solution for points was with Point2D/Point3D, adding a lot of confusion (what is that class and what does .vector()?): Vector3 a = (mPoint3D(v)).vector(); And the worst solution was with generic 2D/3D code (WTF!): auto a = (mtypename DimensionTraits::PointType(v)).vector(); Now it is just this, similar for both dimensions: Vector3 a = m.transformPoint(v); Vector3 b = m.transformVector(v); Note that transformation three-component vectors with 3x3 matrices or four-component vectors with 4x4 matrices is easy enough so it doesn't need any special convenience functions whatsoever: Vector3 c = m.rotation()*v;	13 years ago
