Vladimír Vondruš	a23661a171	Doc++ Missed some leftover && from `7e1a260286`, documented Matrix Implementation::SequenceGenerator a bit, added constexpr todos.	14 years ago
Vladimír Vondruš	f2c37d9dd8	Using explicit constructors for templated type in Vector. E.g. T() instead of 0, T(1) instead of 1. Added just-to-be-sure unit test.	14 years ago
Vladimír Vondruš	ea39f3735e	Vector dot product is now static function instead of operator(). operator is used in GLSL for element-wise multiplication, be compatible with that.	14 years ago
Vladimír Vondruš	e8c76b7d96	Forced exclusive use of bracket operators in Matrix and Vector. Removed functions at(), set() and add(), everything (and more) can be now done using operator[]. Accessing matrix elements is now done through column vectors, e.g.: Matrix4 a; a.at(row, col); // before a[col][row]; // now Note that because operator[] on Matrix returns column vector (there is nothing like row vector), the parameter "order" is now swapped.	14 years ago
Vladimír Vondruš	a3b754b88e	Possiblity for constructing Vector from one value, like in GLSL. Marked the constructor as explicit, because we don't want mistakes like this to happen: Matrix4::rotation(1.0f, deg(3.0f)); // oops, swapped axis and angle! Instead, when calling such constructor, the type must be said explicitly (initializer-list is forbidden, too): Matrix4::rotation(deg(3.0f), Vector3(1.0f)); // okay	14 years ago
Vladimír Vondruš	c8e33a74cc	"constexpr"-ized Matrix and Vector classes. It should improve performance, because what can be computed at compile time is now computed at compile time. In addition these things have been changed or improved: * Removed constructors from T, as they cannot be AFAIK written using constexpr functions only and they only do unnecessary data copying most of the time. The functionality is now provided using static functions Matrix::from() and Vector::from() which returns either const or non-const reference to original data, so no copy is performed. These functions also have explicit warning about unsafe operations. Defaulted copy constructors and assignment operators, using "default initialization" for arrays instead of memsetting it with zeros. It should behave the same and this way we don't need any memcpy(), memset() etc. from <cstring>, which is good.	14 years ago
Vladimír Vondruš	b8f09a0616	Added arithmetic assign operators to Matrix and Vector. Multiplication, division, addition and substraction is now done primarily in assigning operators, as they do the computations in-place, so they are more memory efficient than implementing them using e.g. `this = this+other;`. Updated unit test only for matrix multiplication, as vector unit tests test arithmetic asssign operators too.	14 years ago
Vladimír Vondruš	1f2aa86be3	Fixed awesome bug in Vector3 constructor. Updated unit test to make sure it won't happen again.	14 years ago
Vladimír Vondruš	7a03e48df8	Finally "initializer-list" constructor for Vector. It's not actually initializer list, because it is only for variable-length types, which is unusable here. Variadic templates do better job here.	14 years ago
Vladimír Vondruš	28adf2c98b	Added length parameter to Vector3::[xyz]Axis(). Now you can write e.g. Matrix4::translation(Vector3::xAxis(5.0f)); instead of these: Matrix4::translation(Vector3::xAxis()*5.0f); // slow! Matrix4::translation({5.0f, 0.0f, 0.0f}); // boring!	14 years ago

Vladimír Vondruš	7f24696021	Don't return reference to temporary object in Debug output.	15 years ago
Vladimír Vondruš	cb0efb5d47	Vector3 constructor from Vector2 and optional Z/B value (default 0).	15 years ago
Vladimír Vondruš	31c70f2c08	Doc++	15 years ago
Vladimír Vondruš	0d2f2c966f	Doc++ Updated and simplified Main page of documentation, finally fixed doxygen warnings with @copydoc in Math namespace.	15 years ago
Vladimír Vondruš	58ace7d678	Fixed errors with template two-phase lookup, discovered with GCC 4.7.	15 years ago
Vladimír Vondruš	8555475807	Support for printing Matrix and Vector to debug output. Added tests for Matrix3, Vector2 just to be sure that debug output works also there.	15 years ago
Vladimír Vondruš	b27d5efc04	Propagated dot product operator to Vector specializations. Otherwise GCC doesn't see the operator.	15 years ago
