VectorMath

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.

Sample code

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.

Roadmap

• Disable explicit floating-point functions for integers
• Get rid of STD
• SIMD Support
• Documentation
• More functions!
