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	dd8eb6bc02	Removed one swizzle() overload. It is less efficient because of all that runtime computation and can't be made to use SIMD operations so why bother with it at all.	14 years ago
Vladimír Vondruš	949b092a60	Support for '0' and '1' constants in swizzle() functions. Also deconfused related documentation a bit.	14 years ago
Vladimír Vondruš	6a4b68410c	Doc: brief introduction to matrix and vector classes. DDD - documentation driven development. Not all advertised features are available right now, but they will come.	14 years ago
