Vladimír Vondruš	3d77885555	Revert "Overflow test for large types in Math::normalize() started working." It was working because of some weird state of my build dir, expecting fail again. This reverts commit `75d0505a60`.	14 years ago
Vladimír Vondruš	75d0505a60	Overflow test for large types in Math::normalize() started working. I don't know what caused that... :-)	14 years ago
Vladimír Vondruš	fe62f547de	Reduced #includes in headers. Magnum.h now doesn't include anything except OpenGL headers, thus changes in Math library don't trigger recompilation of everything, but only of things really depending on it. Math constants moved to separate file for similar reasons, de-inlined some functions to remove the need for some #includes.	14 years ago
Vladimír Vondruš	742a75277d	Moved unary operator- from Vector to RectangularMatrix.	14 years ago
Vladimír Vondruš	e21c9ca3a5	Function for computing trace of square matrix.	14 years ago
Vladimír Vondruš	3558859cc6	Utility function for clamping value in given limits.	14 years ago
Vladimír Vondruš	8911dbdffe	Moved multiplication and division from Vector to RectangularMatrix.	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	0e74c3847d	Support for storing matrices and vectors in configuration.	14 years ago
Vladimír Vondruš	2b62cc4012	Prefer to use (col, row) instead of [col][row] on matrices. They should be in theory both compiled to the same code, but in practice [][] sometimes fails during optimization.	14 years ago
Vladimír Vondruš	a5b8afa122	Added Vector2::Scale() and Vector3::Scale(). Complements to *Axis for scaling.	14 years ago
Vladimír Vondruš	b8750d3702	Added Vector2::*Axis(), similar to those in Vector3.	14 years ago
Vladimír Vondruš	0e08138806	Added number*Vector and number/Vector operators.	14 years ago
Vladimír Vondruš	a4c80d18ed	Added component-wise multiplication and division to Vector.	14 years ago
Vladimír Vondruš	fec65aa6f5	Ability to construct Vector from another of different type.	14 years ago
Vladimír Vondruš	129b7f23a7	Fixed typos (substract -> subtract).	14 years ago
Vladimír Vondruš	0177ec8b5d	Moved swizzle() functions to root namespace. They aren't much useful in Math namespace and here it allows to handle also Color3/Color4 types. Moreover all RGBA component names were removed from Math namespace, so it would be inconsistent to have them there only in swizzle() functions.	14 years ago
Vladimír Vondruš	51f2478b1e	More precise double Math constants. Double has 15-17 significant decimal digits precision, extended the constant to have 15 decimal digits. On the other hand, float has only 6-9 digits, so there is no need to have more than 9. Added just-to-be-sure test for sqrt* constants.	14 years ago
Vladimír Vondruš	3bcaed6322	Using round() in denormalization. Gives more precise results for smaller types, but creates overflow for large types.	14 years ago
Vladimír Vondruš	06872c7727	Added Vector::min() and Vector::max().	14 years ago
Vladimír Vondruš	37a5d6347e	Vector::angle() now expects normalized vectors.	14 years ago
Vladimír Vondruš	0a0860a9f2	Renamed Vector::lengthSquared() to parameterless Vector::dot(). It's now less confusing ("length squared" looks like it's even heavier than length), but on the other hand it's not so obvious that these two functions come together.	14 years ago
Vladimír Vondruš	cfc955debe	Added Vector::sum(), so product() has a friend.	14 years ago
Vladimír Vondruš	2553e50444	Functions for normalizing and denormalizing numeric values.	14 years ago
Vladimír Vondruš	c23022d47f	Another, more convenient way to swizzle. On the other hand everything of this is done at runtime, so it's less performant than the previous version, mainly when used in loops. When the result is declared as constexpr, it is done at compile time, just like the previous version. I don't know which version to keep, so there will be both until a good decision.	14 years ago
Vladimír Vondruš	fff22d0822	New function for vector component swizzling.	14 years ago
Vladimír Vondruš	27e1dce533	Got rid of Qt's QtTest in favor of Corrade's TestSuite. Now we can use CORRADE_COMPARE() almost exclusively for comparing Vector, Matrix instances and all containers from STL. Tests running time for all 31 tests is now around 0.1 sec instead of two seconds like before. Disabled compilation of all benchmarks, because TestSuite cannot handle them yet. PKGBUILD from AUR now can shamelessly use check() function without unnecessary dependencies.	14 years ago
Vladimír Vondruš	8b3e065d52	Don't use == when comparing floating point values.	14 years ago
Vladimír Vondruš	27dad83dbc	Don't pretend we are working with floats when they are doubles.	14 years ago
Vladimír Vondruš	8f008c53c5	Support for 2D transformations in addition to 3D in Matrix classes.	14 years ago
Vladimír Vondruš	86b1aaa2af	Reuse most of the already compiled objects for unit test libraries. CORRADE_GRACEFUL_ASSERT is set only on files where it makes sense, the rest is shared between main and test libraries. Speeds up the compilation like infinity times. CMake 2.8.8 is required for OBJECT library target.	14 years ago
Vladimír Vondruš	7f6f81afc7	Math::Constants are now inline functions instead of static variables. Static variables were compiled into the library and then linked on every use, which was not good for performance.	14 years ago
Vladimír Vondruš	4cd1ee140e	Removed Math::TypeTraits to MathTypeTraits to avoid name clash.	14 years ago
Vladimír Vondruš	eddfb62c32	Function for getting first two components of a vector.	14 years ago
Vladimír Vondruš	7ff3c6e40d	Ability to multiply/divide Vector with arbitrary type. Needed for e.g. colors, where the color is stored as Vector3<GLubyte> and it is needed to multiply it with some floating-point value.	14 years ago
Vladimír Vondruš	cc1f9c60c9	Swapped size and type template parameters in Vector and Matrix. Long-standing TODO. It is better to have size first, because it is more significant than type (e.g. because there are Vector4<T> specializations and not VectorT<4> specializations). It is also IMHO easier for user to distinguish/read the type than before: Vector<float, 4> -> Vector4<float> // before Vector<4, float> -> Vector4<float> // now	14 years ago
Vladimír Vondruš	6f94d84b1a	Moved Math::GeometryUtils to Math::Geometry::Intersection. The namespace will contain classes (and functions) for computing intersections, distances, areas and volumes.	14 years ago
Vladimír Vondruš	e921194601	Simplified GeometryUtils::intersection(), updated documentation. The function now takes only plane normal and position instead of three points. Also greatly simplified unit test.	14 years ago
Vladimír Vondruš	2be1ff3763	Added Vector::lengthSquared() function. The name is a little bit misleading, but it is for more efficient vector length comparisons.	14 years ago
Vladimír Vondruš	925cc3d2ff	Make Math::pow() templated on type.	14 years ago
Vladimír Vondruš	0a965cf036	CMakeLists.txt cleanup and style unification. * For libraries that are part of the same project using directly target name instead of ${_LIBRARY} variable. Prefixed test target names with namespace, so tests for the same class in different namespaces won't conflict. * Removed unneeded linking to ${CORRADE_UTILITY_LIBRARY} in some places.	14 years ago
Vladimír Vondruš	f0d88fbf9f	Added templated Math::Constants structure to replace PI #define. And added sqrt(2) and sqrt(3) constants while we are at it.	14 years ago
Vladimír Vondruš	aec8ef98dd	Function for returning rotation and scaling part of Matrix4.	14 years ago
Vladimír Vondruš	ccf61c0f7f	Fixed typo in method name.	14 years ago
Vladimír Vondruš	c14715962d	Use T() instead of static_cast<T>() for numeric types.	14 years ago
Vladimír Vondruš	54af4015f2	Allow to specify value on diagonal in identity matrix constructor.	14 years ago
Vladimír Vondruš	4f1c7ccfa0	Better (hopefully) way to distinguish between Matrix constructors. Before it was one constructor using bool parameter, which is massive antipattern: Matrix4 m(false); // Huh? No Matrix4 then or what? Iẗ́'s now separated into two distinct constructors, of them one can be already declared as constexpr (hooray). The usage is as follows: Matrix4 a; // Default (identity matrix) Matrix4 b(Matrix4::Identity); // Explicitly identity matrix Matrix4 c(Matrix4::Zero); // Zero-filled matrix Also deleted constructor from one parameter, so following mistakes now cannot compile: Matrix4 d(true); // Both would set element at [0][0] to 1, Matrix4 e(Matrix3::Zero); // and other to 0	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	071180ebcd	Function for getting rotation part of Matrix4.	14 years ago
