SharpDX Inspired C++ vector math library (scalar only).
Status: Production Ready
VectorMath was designed to be flexible, allows to define vectors using any integer/floating-point type. Just drag and drop source and header files into your project! That's it.
View Projection matrix calculation
m_lookAt = m_position + m_forward; m_view = Matrix::CreateLookAt(m_position, m_lookAt, m_up); m_projection = Matrix::CreatePerspective(Math::DegreeToRadian * m_fov, Display::GetAspectRatio(), m_nearPlane, m_farPlane); m_viewProjection = m_view * m_projection; // ... auto transformed = Vector3::Transform(somePoint, m_viewProjection);
Vector2/3/4 functionality
const auto someVector = Vector3(0.0f, 2.0f, 1.0f); auto normalized = Vector3::Normalize(someVector); auto dot = Vector3::Dot(someVector, normalized); if(normalized.IsNormalized()) {...} if(normalized.IsNaN()) {...} if(normalized.Length() > 2) {...} // ...
Quaternion functionality
const auto someRotation = Quaternion(Vector3::Up, 50.0f); auto axis = someRotation.Axis(); if(someRotation.IsNormalized()) {...} if(someRotation.IsNaN()) {...} if(someRotation.Length() > 2) {...} // ...
Note: Quaternions are built with float as their default type and there is no way to change it.
Defining new vector type
using Vector2i = Vector2Base<int>; using Vector3i = Vector3Base<int>; using Vector4i = Vector4Base<int>;
Already there are some ready-to-use types defined in the VectorMath.h file.
By default UPPERCASE component naming is enabled, look: Config.h.
- Disable explicit floating-point functions for integers
- Get rid of STD
- SIMD Support
- Documentation
- More functions!
I do accept PR. Feel free to contribute.
