Vladimír Vondruš	f91f464ec8	GCC 4.4 compatibility: better solution for explicit conversion of Unit. Having implicit conversion on Unit class causes much more harm than doing the conversion some other way -- mainly for multiplication and division, which is done with builtin operators and thus the result is unitless. Also it is possible to do wrong "retyping" between degrees and radians: Rad a = Constants::pi(); Deg b(a*2); On GCC >4.5 b is `180`, but on GCC 4.4 it is `2pi`, which is obviously wrong and not wanted. The conversion is done using Unit::toUnderlyingType() which is now used everywhere instead of conversion operator. The conversion operator is made available only for GCC 4.5, where it can be marked as explicit. This might cause incompatibilites with `master` branch, where no Unit::toUnderlyingType() exists, but users should have no need to convert it to underlying type anyway as all required functions are available through the library. This reverts commit `36ac4de5c4` and partially also `0db3a183ae` (UnitTest.cpp).	13 years ago

Vladimír Vondruš	cc938a29dd	Math: test that implicit conversion of T to Vector<T> won't compile. "Won't compile" tests are another awesome feature of C++11.	13 years ago
Vladimír Vondruš	45ba444fb8	Math: properly test conversion constexpr also in Vector subclasses.	13 years ago
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	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	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	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
