Magnum::Math
— a graphics-focused vector math library
https://doc.magnum.graphics/magnum/namespaceMagnum_1_1Math.html
https://doc.magnum.graphics/magnum/namespaceMagnum_1_1EigenIntegration.html
https://doc.magnum.graphics/magnum/namespaceMagnum_1_1GlmIntegration.html
This is a single-header library generated from the Magnum project. With the
goal being easy integration, it's deliberately free of all comments to keep
the file size small. More info, changelogs and full docs here:
- Project homepage — https://magnum.graphics/magnum/
- Documentation — https://doc.magnum.graphics/
- GitHub project page — https://github.com/mosra/magnum
- GitHub Singles repository — https://github.com/mosra/magnum-singles
v2020.06-0-gfac6f4da2 (2020-06-27)
- Various fixes for Clang-CL compatibility
- Expanding the APIs to work with Half and long double types
- Magnum::Math::NoInit is now Magnum::NoInit
- Minor changes for faster performance of dot() and cross() in Debug
- Added reflect() and refract() functions
- slerp() / slerpShortestPath() falls back to linear interpolation for
quaternions that are close together, instead or always returning the
first
- Added Quaternion::toEuler()
- Added transformVector() to DualComplex and DualQuaternion to have the
the same set of APIs as with Matrix3 / Matrix4
- Mutable access to Frustum planes
- Fixed implicit conversion of std::pair to Range*D
- New BoolVector[234], 8-/16-bit and half-float vector and matrix
convenience typedefs
v2019.10-0-g8412e8f99 (2019-10-24)
- New IsScalar, IsVector, IsIntegral, IsFloatingPoint type traits,
correct handling of Deg and Rad types in all APIs
- Guaranteed NaN handling semantic in min()/max()/minmax() APIs
- Using a GCC compiler builtin in sincos()
- swizzle() is replaced with gather() and scatter()
- Added Matrix::{cofactor,comatrix,adjugate}(), Matrix4::normalMatrix()
- New Matrix4::perspectiveProjection() overload taking corner positions
- Handling also Eigen::Ref types; EigenIntegration::eigenCast() is now
just EigenIntegration::cast()
v2019.01-241-g93686746a (2019-04-03)
- Initial release
