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

Vladimír Vondruš	a0b8dcc067	Math: rename Quaternion::fromRotation() to rotation(). Now it is similar in usage to Matrix4 functions and is now also crossreferenced in documentation. Also updated the test to also check assertion.	13 years ago

Vladimír Vondruš	730c09567d	Math: ability to explicitly create Quaternion for given vector.	13 years ago
Vladimír Vondruš	0144c38a54	Math: moved lerp() from Vector to Functions.h. It does nothing special for vectors (unlike e.g. quaternion LERP) and scalar overload is useful too.	13 years ago
Vladimír Vondruš	baeadc9663	Math: matrix/vector rework, part 2: matrix as array of column vectors. Overall architecture is simplififed with this change and also it's not needed to use reinterpret_cast in matrix internals anymore, thus there is no need for operator() and [][] works now always as expected without any risk of GCC misoptimizations. On the other side, constructing matrix from list of elements is not possible anymore. You have to specify the elements as list of column vectors, which might be less convenient to write, but it helps to distinguish what is column and what is row: Matrix<2, int> a(1, 2, // before 3, 4); Matrix<2, int> a(Vector<2, int>(1, 2), // now Vector<2, int>(3, 4)); For some matrix specializations (i.e. Matrix3 and Matrix4) it is possible to use list-initialization instead of explicit type specification: Matrix<3, int>({1, 2, 3}, {4, 5, 6}, {7, 8, 9}); I didn't yet figure out how to properly implement the general (constexpr) constructor to also take lists, so it's a bit ugly for now. Matrix operations are now done column-wise, which should help with future SIMD implementations, documentation is also updated accordingly. I also removed forgotten remains of matrix/matrix operator*=(), which can be confusing, as the multiplication is not commutative. Why it is not present is explained in `d9c900f076`.	13 years ago

Vladimír Vondruš	eeed955154	Minor code cleanup.	14 years ago
Vladimír Vondruš	d9c900f076	Doc++ * Added math equations to Quaternion, Vector and Matrix method documentation. * Removed confusing Quat=Quat operator overload, as it isn't exactly clear from which side the non-commutative multiplication is done: Quaternion a; a = b; // eh? a = ab; // okay! For similar reason this operator wasn't present in RectangularMatrix either. Unified documentation of expected vector/quaternion normalization state. Now it is not "assumed" but "expected", because failing to do so results in assertion failure.	14 years ago
