Vladimír Vondruš	227517ff89	Math: added DualQuaternion::transformPoint().	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	3ad264893e	Math: creating rotation and translation DualQuaternion.	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	e24207f620	Doc++	13 years ago
Vladimír Vondruš	5819dd4bd7	Math: matrix/vector rework, part 3: conversion as explicit constructor. Also updated all dependent classes to follow the change, such as Color and Rectangle. Backwards compatibility for GCC 4.6 (with lack of support for delegating constructors) will be done as non-constexpr constructor using operator=().	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	d175dd1054	Updated workarounds for Doxygen 1.8.2. Removed workarounds for alias templates, variadic templates and anonymous enums, but 1.8.2 has some bug with forward declarations causing classes to appear in default namespace, breaking cross-references.	13 years ago
Vladimír Vondruš	7d0a523618	Moved projection matrix computation to Math namespace.	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
Vladimír Vondruš	d981090e86	Functions for inverting Euclidean transformation matrices.	14 years ago
Vladimír Vondruš	e9e0de70d7	Implemented reflection matrices. Long-standing TODO, can be used for in-game mirrors etc. I give up with shearing, as I think that it makes sense only in 2D and I can't find any reasonable use case for that yet.	14 years ago
Vladimír Vondruš	6ae94bffd7	Ability to construct Matrix from rotation/scaling and translation parts.	14 years ago
Vladimír Vondruš	7e66a09461	Marking all constructors explicit, except for matrix and vector classes. It prevents unwanted implicit conversions from e.g. nullptr to Camera, Vector2 to Physics::Point etc. By making all the constructors explicit it is easier to routinely add the keyword to all new classes instead of thinking about cases when to add and when not to.	14 years ago
Vladimír Vondruš	9ead1e9deb	Thorough documentation review and update. Now whole Magnum, Magnum::SceneGraph and Magnum::Math namespaces are fully documented -- each class has at least "getting started" documentation, larger modules are documented on separate pages.	14 years ago
Vladimír Vondruš	8a3d2c12c6	Doc++ Crosslinked types from Math namespace with typedefs in Magnum namespace.	14 years ago

Vladimír Vondruš	b5fc786478	Renamed Matrix4::[xyz]Rotation() to Matrix4::rotation[XYZ](). * "Rotation around [XYZ]" makes more sense than "[XYZ] axis rotation". * This naming will appear in autocompletion. * SceneGraph transformation methods will be named similarly rotate[XYZ]() (because [xyz]Rotate() is weird even more).	14 years ago
Vladimír Vondruš	f707e91599	Better parameter names in Matrix transformation methods. Mainly it is now explicitly stated in parameter name that rotation axis must be normalized.	14 years ago
Vladimír Vondruš	f28f5398d3	Added some @todos .	14 years ago
Vladimír Vondruš	2c52f7b85a	Non-explicit default constructor for Vector2 and Matrix*. So you can now write mat = {}; vec = {}; instead of mat = Matrix3(); vec = Vector2();	14 years ago

Vladimír Vondruš	93961aca65	Don't include Matrix3 in Matrix4, as it isn't used. Also updated includes in dependent headers.	14 years ago
Vladimír Vondruš	9e24a7bca0	Don't return Matrix3 from Matrix4 member functions. Matrix3 is for 2D affine transformations, while Matrix4 is for 3D. Returning Matrix3 would allow doing this, which isn't meaningful operation at all: Matrix4 transformation; Vector2 wtf = transformation.rotationScaling().translation();	14 years ago

Vladimír Vondruš	4bcc805616	Moved add/subtract operators from Vector to RectangularMatrix.	14 years ago
Vladimír Vondruš	90881e7337	New base for matrices and vectors: RectangularMatrix. Currently moved only non-square functionality from Matrix there. Also static constant members such as row/column count and size are now lowercase, as they are variables, not types.	14 years ago

Vladimír Vondruš	4aa07d3029	Use std:: variants for sin(), cos() and sqrt(). They should have overloads for given type, so we're not using doubles when only float is needed.	14 years ago
Vladimír Vondruš	8f008c53c5	Support for 2D transformations in addition to 3D in Matrix classes.	14 years ago

Vladimír Vondruš	9d31231471	Pedantic: first inline, then constexpr, then static. Moreover all constexpr functions are meant to be inline here, mark them as such.	14 years ago
Vladimír Vondruš	1be7b8b9c2	Workarounds for Clang parsing issues.	14 years ago
Vladimír Vondruš	208b6ce93e	Custom @debugoperator command instead of hiding the functions. Uses @relates, so the operator is tied to related class.	14 years ago
