Vladimír Vondruš	cbcb73a9d5	GCC 4.5 compatibility: this workaround is not needed anymore. Due to Matrix/Vector rework and other changes this is fixed on lower levels already. The tests pass on both 4.5 and 4.4, hopefully it won't break anywhere else.	13 years ago
Vladimír Vondruš	48bb1f1cb0	GCC 4.4 compatibility: workarounds for strict-aliasing fascism. These four cover most (but not all) warnings when compiling in Release mode. Now all the tests pass, but the warnings signalize that something could go bad somewhere else. However, only one drastic solution comes to my mind at this time -- disabling strict aliasing completely `-fno-strict-aliasing`. Don't know performance impact of that.	13 years ago
Vladimír Vondruš	83bda8bbe6	Math: fixed test for denormalize<UnsignedLong, long double>(). Amazing what single forgotten literal can do.	13 years ago
Vladimír Vondruš	35eb876303	Various other compilation fixes for OpenGL ES target.	13 years ago
Vladimír Vondruš	ba0f56fa51	No need to use Double type in tests so extensively. Makes porting to OpenGL ES easier.	13 years ago
Vladimír Vondruš	b28261d269	Math: fix compilation of tests with OpenGL ES. Double precision is not supported there, mention that for skipped test cases.	13 years ago
Vladimír Vondruš	be5c872c8a	Math: fixed two typos in the test. They resulted in fact that the test case didn't actually test anything. Spotted by Clang.	13 years ago
Vladimír Vondruš	cb7a0f6404	GCC 4.5 compatibility: can't list-initialize array of classes. Awesome bug. In GCC 4.6 it throws plenty of ungoogleable `-pedantic` warnings and in GCC 4.5 it fails directly with "error: bad array initializer". Fallback to initialization using for-cycle. Worked around that in 4.6 by disabling `-pedantic` warnings, must be done this way on 4.5 & 4.4. Hopefully the performance won't be harmed too much.	13 years ago
Vladimír Vondruš	fcb756e42a	Revert "GCC 4.6 compatibility: can't list-initialize array of classes." It does too much harm on GCC 4.6 (all these constexpr constructors are not constexpr now). We can disable that `-pedantic` warning for GCC 4.6 only and live with that. This reverts commit `2d92d497d9`.	13 years ago
Vladimír Vondruš	125e01f62e	GCC 4.4 compatibility: no std::declval here.	13 years ago
Vladimír Vondruš	36ac4de5c4	GCC 4.4 compatibility: no explicit conv op on Unit and related issues. Using Deg/Rad on GCC 4.4 will be bigger PITA than I thought.	13 years ago
Vladimír Vondruš	10440bf503	GCC 4.4 compatibility: no explicit conversion operators.	13 years ago
Vladimír Vondruš	5ad38775b0	GCC 4.5 compatibility: various constexpr issues.	13 years ago
Vladimír Vondruš	dd788285dc	Various code cleanup.	13 years ago
Vladimír Vondruš	2d92d497d9	GCC 4.6 compatibility: can't list-initialize array of classes. Awesome bug. In GCC 4.6 it throws plenty of ungoogleable `-pedantic` warnings and in GCC 4.5 it fails directly with "error: bad array initializer". Fallback to initialization using for-cycle. Hello, performance? You can go home now.	13 years ago
Vladimír Vondruš	999b7d55c0	GCC 4.6 compatibility: no delegating constructors. Don't know why the corresponding conversion operator can't be constexpr.	13 years ago
Vladimír Vondruš	ba105b1cf6	Math: test constexpr vector conversion.	13 years ago
Vladimír Vondruš	7b140db3ed	Properly test swizzle() constexpr. Removed constExpressions() test case and merged it to others, reducing duplicate code.	13 years ago
Vladimír Vondruš	ce6f999904	Math: better isNormalized() implementation. Comparing squared length to 1 is not sufficient to compare within range [1 - epsilon, 1 + epsilon], as e.g. Quaternion with dot() = 1 + 1e-7 when converted to matrix has column vectors with dot() = 1 + 1e-6, which is just above 1 + epsilon. Thus it's needed to compare sqrt(dot()) in range [1 - epsilon, 1 + epsilon] or dot() in range [1 - 2epsilon + epsilon^2, 1 + 2epsilon + epsilon^2]. Because epsilon^2 is way off machine precision, it's omitted, thus dot() in all isNormalized() implementations is now compared this way: abs(dot() - 1) < 2*epsilon;	13 years ago
Vladimír Vondruš	f4f44d9d90	Math: allow creating DualComplex/DualQuaternion from real part only. Useful when creating transformation from rotation only.	13 years ago
Vladimír Vondruš	4744b631bb	Math: test pow() constexpr.	13 years ago
Vladimír Vondruš	7cb79b145e	Math: test Constants constexpr.	13 years ago
Vladimír Vondruš	b28b90a9df	Math: merged constExpressions() test cases into other test cases. Simplifies the code and reduces duplicates.	13 years ago
Vladimír Vondruš	3e0e91d7db	Math: renamed {rotationAngle, rotationAxis}() -> {rotation, angle, axis}(). DualQuaternion and DualComplex has now only rotation() which returns full rotation part, rotationAngle() and rotationAxis() on Quaternion and Complex were renamed to angle() and axis().	13 years ago
Vladimír Vondruš	73a4e9b18a	Math: doc++	13 years ago
Vladimír Vondruš	da2bbac104	Math: simplified Matrix::isOrthogonal(). No need to call std::abs() when comparing with zero, as dot() should always be positive.	13 years ago
Vladimír Vondruš	b00554fd7f	Math: added convenience {Quaternion,DualQuaternion}::isNormalized().	13 years ago
Vladimír Vondruš	1790f37295	Math: added convenience functions {Complex,DualComplex}::isNormalized().	13 years ago
Vladimír Vondruš	3db2aa13c4	Math: added convenience function Vector::isNormalized().	13 years ago
Vladimír Vondruš	da93b2ad6a	Math: ability to create Quaternion and DualQuaternion from matrix.	13 years ago
Vladimír Vondruš	9128820e35	Math: ability to create Complex and DualComplex from matrix.	13 years ago
Vladimír Vondruš	33058aa5b0	Math: Matrix::invertedOrthogonal(), Matrix{3,4}::invertedRigid(). Renamed original invertedEuclidean() functions to invertedRigid() and simplified them using isRigidTransformation().	13 years ago
Vladimír Vondruš	dfe2571047	Math: added Matrix{3,4}::isRigidTransformation().	13 years ago
Vladimír Vondruš	4714cafedc	Math: added Matrix::isOrthogonal().	13 years ago
Vladimír Vondruš	408f40a908	Math: renamed MathTypeTraits to TypeTraits. As there is no Magnum::TypeTraits struct anymore, there is no need to have redundant name in it. Hopefully Doxygen will handle the difference between this and Corrade's TypeTraits.h properly.	13 years ago
Vladimír Vondruš	75d8fefdde	Math: ability to access also matrix row vectors.	13 years ago
Vladimír Vondruš	a0b83edd2b	Relicensing to MIT/Expat license, part 4: CMake and documentation files. They didn't contain license header before, but I think adding it also there wouldn't do any harm. Documentation is also integral part of the codebase.	13 years ago
Vladimír Vondruš	c5ab86794b	Relicensing to MIT/Expat license, part 3: source files. Added license header also to shader sources. Hopefully it won't harm compilation times too much.	13 years ago
Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	90a60ce7e9	Math: disable denormalize() test for UnsignedLong. It works with GCC and -O3, but fails on unoptimized code.	13 years ago
Vladimír Vondruš	90dbb28763	Thorough CMakeLists cleanup. * Calling enable_testing() only in root path. * Using CORRADE_CXX_FLAGS instead of our own set to make things easier to maintain. * Various cleanup and reorganization.	13 years ago
Vladimír Vondruš	297d102200	Math: ability to convert Vector types from/to external types.	13 years ago
Vladimír Vondruš	231f3277ab	Adapted to Corrade changes. Allowing to instantiate Trade::AbstractImporter subclasses directly without plugin manager.	13 years ago
Vladimír Vondruš	31582ce2f8	Todo++	13 years ago
Vladimír Vondruš	677aa8485e	Math: properly test constexpr in all Matrix classes. * Merged constExpressions() into other test cases, reducing duplicates and simplifying the checks. * Fixed old-and-forgotten operator[] overload in Matrix subclasses, it was reinterpret_cast on T* array, it is now sufficient to do only static_cast. Constexpr operator[] overload returns const copy to make constexpr operations working even on returned value, e.g.: constexpr Matrix4 a; constexpr Vector3 b = a[2].xyz();	13 years ago
Vladimír Vondruš	fc538c3a57	Math: properly test constexpr in all Vector classes. * Merged constExpressions() into other test cases, simplified the test a lot and removing duplicate code. * Fixed Vector3::xy(), Vector3::xy() and Vector3::xyz() constexpr overloads, they now return copy instead of reinterpret_cast reference. The copy is const to make constexpr operations working even on returned subclass, e.g.: constexpr Vector4 a; constexpr Float b = a.xyz().y();	13 years ago
