Vladimír Vondruš	7ef8432fbe	Doxygen: ignore specific namespaces instead of whole directories. Less maintenance burden with `#ifndef DOXYGEN_GENERATING_OUTPUT`, removed the ones which are not needed anymore.	13 years ago
Vladimír Vondruš	ce6f999904	Math: better isNormalized() implementation. Comparing squared length to 1 is not sufficient to compare within range [1 - epsilon, 1 + epsilon], as e.g. Quaternion with dot() = 1 + 1e-7 when converted to matrix has column vectors with dot() = 1 + 1e-6, which is just above 1 + epsilon. Thus it's needed to compare sqrt(dot()) in range [1 - epsilon, 1 + epsilon] or dot() in range [1 - 2epsilon + epsilon^2, 1 + 2epsilon + epsilon^2]. Because epsilon^2 is way off machine precision, it's omitted, thus dot() in all isNormalized() implementations is now compared this way: abs(dot() - 1) < 2*epsilon;	13 years ago
Vladimír Vondruš	3e0e91d7db	Math: renamed {rotationAngle, rotationAxis}() -> {rotation, angle, axis}(). DualQuaternion and DualComplex has now only rotation() which returns full rotation part, rotationAngle() and rotationAxis() on Quaternion and Complex were renamed to angle() and axis().	13 years ago
Vladimír Vondruš	73a4e9b18a	Math: doc++	13 years ago
Vladimír Vondruš	b00554fd7f	Math: added convenience {Quaternion,DualQuaternion}::isNormalized().	13 years ago

Vladimír Vondruš	408f40a908	Math: renamed MathTypeTraits to TypeTraits. As there is no Magnum::TypeTraits struct anymore, there is no need to have redundant name in it. Hopefully Doxygen will handle the difference between this and Corrade's TypeTraits.h properly.	13 years ago
Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	618b556381	Math: crosslinked documentation with missing type aliases.	13 years ago

Vladimír Vondruš	8913e38432	Math: documented this whole transformation thingy.	13 years ago
Vladimír Vondruš	14460cf0f4	Math: renamed *::matrix() to ::toMatrix(). It better visualizes the fact that neither (Dual)Complex nor (Dual)Quaternion contains the matrix inside them, but performs (possibly costly) conversion.	13 years ago
Vladimír Vondruš	7aac5bd70b	Math: no need for Complex::transformVectorNormalized(). Unlike quaternions it doesn't need inversion or normalization for transforming vectors.	13 years ago

Vladimír Vondruš	728b9a3f2e	Math: construct identity transformation by default. Square matrices already had that, (dual) quaternions too, making that the default also with complex numbers. Updated the documentation to reflect that.	13 years ago

Vladimír Vondruš	389e9194e0	Math: doc++	13 years ago
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	95982e5176	Math: various code cleanup.	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
