Detailed Description

template<typename Valtype>
struct spat::PositionH< Valtype >

Implements a 4D - position in homogenous coordinates.

Specifies the coordinates of a point in 3D space. For Vectors, like e.g. surface normals, use the Vector type.

Member Function Documentation

Equals()

template<typename Valtype>

bool spat::PositionH< Valtype >::Equals ( const PositionH< Valtype > & p, Valtype epsilon = Valtype{0} ) const

inlinenoexcept

Comparison within some range. The area within two positions regarded as equal is a sphere with radius epsilon.

Parameters

p	PositionH to compare with.
epsilon	Distance <= wich two positions are regarded as equal.
