Vladimír Vondruš	5673cf2656	Math: better documentation for vector/quat constructors.	13 years ago
Vladimír Vondruš	0274ad7d56	Math: explicit one-parameter PointD constructor. Was causing improper implicit conversions, such as here (example directly from unit tests, where it was unintentionally used): Vector3 normal; Matrix4 transformation; auto transformedNormal = transformationnormal; Not only that it was possible to multiply 4x4 matrix with 3-component vector, but the resulting type was Point3D which was absolutely confusing. Currently it must be explicitly converted: transformedNormal = transformation*Point3D(normal);	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	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	6a2ebf5c3d	Fixed Vector, Point and Color constructors from smaller types. Currently, when accidentaly creating specialized Vector from smaller number of components than required, the error message isn't really helpful, as it stops on static assert on wrong number of arguments passed to RectangularMatrix: Vector3(0, 1); // static assert: wrong number of arguments passed to // RectangularMatrix<1, 2> -- wtf?! Now the first argument is Vector2/Vector3 instead of Vector<2>/Vector<3> and the error message now properly states that no matching constructor was found.	14 years ago

Vladimír Vondruš	6aa7e3e806	Added Point*D::vector() function. Equivalent to xy() and xyz(), useful for seamless 2D/3D integration.	14 years ago
Vladimír Vondruš	9feb8d32a5	Overloaded operators also for Point2D and Point3D.	14 years ago
Vladimír Vondruš	071afa0b7a	PointD Vector subclasses for homogeneous coordinates. Vector4 doesn't set W component to one by default anymore, this is now handled by Point*D itself. This finally allows creating of 2D primitives and 2D position vectors without messing explicitly with Z = 1. All classes which should use Point instead of Vector were updated to use Point instead.	14 years ago
