Vladimír Vondruš	89c76e2267	Trade: got rid of Point2D/3D in MeshData in favor of Vector2/Vector3. Positions were originally done using Point2D/3D to simplify their transformation using matrices and to some extent simplify their usage in shaders. But now the disadvantages exceeded the advantages: * They take 50% more for 2D positions and 33% more for 3D positions, as last coordinate is always equal to 1, on the other hand when last coordinate is errorneously not equal to 1 they have crazy behavior. * Normalizing them or transforming them with anything else than with matrices is PITA, as we need to strip the last component, do the transformation, and then add the component back. * All transformation handling classes (Complex, DualComplex, Quaternion, DualQuaternion, Matrix3, Matrix4) now have convenience functions for transforming points specified directly as Vector2/Vector3 (and also for transforming vectors). * When someone wants to use homogeneous coordinates with crazy last component values, they can do so with plain Vector3 for 2D and Vector4 for 3D and it will be less confusing than using Point2D/3D which no important detail hidden.	13 years ago
Vladimír Vondruš	556c714805	Primitives: fixed Icosphere subdivision.	13 years ago
Vladimír Vondruš	c2f4359bd7	Math: added strongly-typed asin(), acos() and atan().	13 years ago
Vladimír Vondruš	3379e6c794	Ability to send less than all attribute components to the shader. Remaining unspecified components are set to 0, 0, 1, according to spec. Also cleaned up and simplified the internals, added debug output operators for attribute component count and types and tested the whole thing.	13 years ago
Vladimír Vondruš	24bd924aa5	Consistent naming of attribute types in AbstractShaderProgram.	13 years ago
Vladimír Vondruš	77d9773d37	Removed linkage of AbstractShaderProgram::Attribute::Location. It now doesn't appear in symbol lists, avoiding nasty linker issues.	13 years ago

Vladimír Vondruš	122b1f3bbd	Require HarfBuzz in FindMagnum.cmake only if it was compiled with it.	13 years ago
Vladimír Vondruš	8e3005d625	Updated FindGLEW.cmake, fixed Windows support. On Win it needs both .dll and .lib to be successfully linked, currently the variables must be set manually.	13 years ago
Vladimír Vondruš	b38ec8152b	Text: ability to compile the library without HarfBuzz support. The text will be rendered without all the nifty features like kerning and it will most probably fail on everything non-latin, but HarfBuzz is currently PITA on some systems. HarfBuzz usage can be configured using USE_HARFBUZZ CMake option.	13 years ago
Vladimír Vondruš	1cf2087817	Text: code cleanup -- merged two loops into one.	13 years ago
Vladimír Vondruš	92fb224380	Partially revert "Work-around preprocessor issues on Windows." Commit `99be617278` moved the #undef from SceneGraph/Camera3D.h to Math/Matrix4.h, but it seems that it needs to be in both places.	13 years ago

Vladimír Vondruš	ff929c04e9	Math: type-safe implementation for degrees and radians. Next few commits will add requirement for "strongly typed" angles in all function parameters, e.g.: Matrix3::rotation(24.0_degf); Math::sin(1.047_radf); The purpose is to make angle entering less error-prone, e.g. not passing degrees when radians should be etc.	13 years ago
Vladimír Vondruš	f1e3453517	Math: base class for units.	13 years ago
Vladimír Vondruš	687bd37b81	Math: initial complex number implementation.	13 years ago
Vladimír Vondruš	b32594c363	Explicitly link MagnumMathTestLib to Corrade's Utility library. Would be linked later along TestSuite, but the linker complained now.	13 years ago
Vladimír Vondruš	4e331cabbb	Fix linker issues on Windows. MagnumSceneGraphTestLib didn't have MagnumSceneGraph[Objects]_EXPORT defined, thus failing at link time, similar issue with MagnumMeshToolsTestLib.	13 years ago
Vladimír Vondruš	99be617278	Work-around preprocessor issues on Windows. I hate windows.h.	13 years ago

Vladimír Vondruš	227517ff89	Math: added DualQuaternion::transformPoint().	13 years ago
Vladimír Vondruš	7e0d8d119f	Math: ability to normalize DualQuaternion. Also hope that this is proper implementation.	13 years ago
Vladimír Vondruš	12c786c408	Math: renamed DualQuaternion::norm() to length(), added lengthSquared(). Hopefully this is properly implemented and properly named. On the other hand, having length everywhere (vectors, quaternions, complex numbers) and norm only at one place is inconsistent.	13 years ago
Vladimír Vondruš	f1da7a08b4	Math: added sqrt() overload for Dual.	13 years ago
Vladimír Vondruš	fec6822187	Math: added sqrt() scalar/vector overload.	13 years ago

Vladimír Vondruš	07c0c4d845	Math: added tests for composed dual quaternion parts. To be sure everything is implemented properly.	13 years ago
Vladimír Vondruš	a49bb0d718	Math: convenience functions for transforming vectors with matrices. It's now possible to conveniently transform 2D vectors and points with 3x3 matrices and 3D vectors/points with 4x4 matrices. Previous most low-level solution: Matrix4 m; Vector3 v; Vector3 a = (mVector4(v, 1.0f)).xyz(); Vector4 b = (mVector4(v, 0.0f)).xyz(); Another, more generalized solution for points was with Point2D/Point3D, adding a lot of confusion (what is that class and what does .vector()?): Vector3 a = (mPoint3D(v)).vector(); And the worst solution was with generic 2D/3D code (WTF!): auto a = (mtypename DimensionTraits::PointType(v)).vector(); Now it is just this, similar for both dimensions: Vector3 a = m.transformPoint(v); Vector3 b = m.transformVector(v); Note that transformation three-component vectors with 3x3 matrices or four-component vectors with 4x4 matrices is easy enough so it doesn't need any special convenience functions whatsoever: Vector3 c = m.rotation()*v;	13 years ago
