Detailed Description

4-dimensional homogeneous vector.

Member Function Documentation

dotProduct()

float ParaEngine::Vector4::dotProduct ( const Vector4 &  vec ) const

inline

Calculates the dot (scalar) product of this vector with another.

Parameters

vec	Vector with which to calculate the dot product (together with this one).

Returns

A float representing the dot product value.

operator=()

Vector4& ParaEngine::Vector4::operator= ( const Vector4 &  rkVector )

inline

Assigns the value of the other vector.

Parameters

rkVector

The other vector

transformAffine()

ParaEngine::Vector4 ParaEngine::Vector4::transformAffine ( const Matrix4 &  M ) const

inline

row vector: 4-D Vector transformation specially for affine matrix.

Note

The matrix must be an affine matrix.
