Vladimír Vondruš	35eb876303	Various other compilation fixes for OpenGL ES target.	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	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	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	6a90b0231b	Math: using new aliases for builtin types in whole Math namespace.	13 years ago
Vladimír Vondruš	6eeac71290	Math: Use default pure equality comparison for arbitrary types.	13 years ago
Vladimír Vondruš	ec23a3d13c	Minor code cleanup.	14 years ago
Vladimír Vondruš	ee5f8766af	Math: make type traits aware of long double.	14 years ago
Vladimír Vondruš	03789a5b4b	Math: got rid of MathTypeTraits::NumericType. Was workaround for printing chars with Corrade::Utility::Debug as integers, not needed anymore.	14 years ago
Vladimír Vondruš	6e6e53886d	Removed dead code.	14 years ago
Vladimír Vondruš	3b37dfa6b8	Deleted constructors of classes with only static members. They shouldn't be instantiated, prevent mistakes with this.	14 years ago
Vladimír Vondruš	438bd52bf3	Doc++	14 years ago
Vladimír Vondruš	00d4285cc4	GCC 4.5 compatibility: missing includes.	14 years ago
Vladimír Vondruš	bf55b5854b	TypeTraits: Default inheritance type for structs is public. Simplified already too long lines.	14 years ago
Vladimír Vondruš	c1cf94fb46	Using fixed-size integer types also everywhere else. It solves issues with int/long int/long long int ambiguity, which is good.	14 years ago
Vladimír Vondruš	0145343d59	Pedantic: using std::size_t instead of size_t from C compat headers.	14 years ago
Vladimír Vondruš	70402d687f	Added missing #include.	14 years ago
Vladimír Vondruš	c451b22392	Revert "Documentation: organizing the classes into "modules"." It only caused another maintenance burden and was confusing to users. Now when scene graph is in SceneGraph namespace there is no need for another grouping. Namespaces are (and should be) sufficient. This reverts commit `79945ab6fc`. Conflicts: src/BufferedImage.h src/BufferedTexture.h src/Framebuffer.h src/Query.h src/SceneGraph/Scene.h	14 years ago
Vladimír Vondruš	6c111182e1	WTF? sizeof(int) != 8 and sizeof(long long) != 16. F'ed up in `57d6ded237`.	14 years ago
Vladimír Vondruš	57d6ded237	Added NumericType and FloatingPointType to Math::MathTypeTraits. NumericType is corresponding numeric type with size at least the same as int. It is used in debug operators for Matrix and Vector to prevent printing chars as characters. If the type isn't already floating-point, FloatingPointType is corresponding larger type with sufficient size for normalization of given integral type. Also updated type traits for long types, they are now subclassed either from int or long long based on sizeof(long).	14 years ago
Vladimír Vondruš	95ca0754f5	Hide MathTypeTraits implementation in Implementation namespace.	14 years ago
Vladimír Vondruš	ee62d39e6f	Initial work for GCC 4.5 compatibility. GCC 4.5 doesn't know constexpr keyword and nullptr. As all constexpr functions are here inline, it can be done with a simple macro.	14 years ago
Vladimír Vondruš	9d31231471	Pedantic: first inline, then constexpr, then static. Moreover all constexpr functions are meant to be inline here, mark them as such.	14 years ago
Vladimír Vondruš	79945ab6fc	Documentation: organizing the classes into "modules". While namespaces act for hierarchy, modules are something like "tags" - usable when you want to check related classes of e.g. CubeMapTexture. Not sure how to name module for Math and Physics namespaces and Contexts/Trade, though.	14 years ago
Vladimír Vondruš	fa69b04dcb	MathTypeTraits: part of the original reasons was true.	14 years ago
Vladimír Vondruš	1ce0e68f0f	Doc: better reason for functions in type traits. Also moved this to @internal instead of plain comment.	14 years ago
Vladimír Vondruš	4cd1ee140e	Removed Math::TypeTraits to MathTypeTraits to avoid name clash.	14 years ago
Vladimír Vondruš	d1dd06aa0a	Ability to explicitly specify precision for floating-point equality.	14 years ago
Vladimír Vondruš	9e81d4b6c3	Fixed awesome mistake in Math::TypeTraits. Epsilon value for integral types should be 1, not 0. Updated documentation and test to reflect the change.	14 years ago
Vladimír Vondruš	f585d39146	Added Math::TypeTraits, implementing fuzzy comparison based on type. Fuzzy comparison is implemented only on floating-point types with type-specific epsilon, on integral types classic operator== is used. TypeTraits class is now extension of Math::TypeTraits (where it makes sense).	14 years ago
