Detailed Description

Basic type: 3-dimensional floating point range.

This class represents a 3-dimensional range (or interval) All operations are component-wise and conform to interval mathematics. An empty range is one where max < min. The default empty is [FLT_MAX,-FLT_MAX]

Member Function Documentation

bool GfRange3f::Contains ( const GfVec3f & point ) const

inline

Returns true if the point is located inside the range. As with all operations of this type, the range is assumed to include its extrema.

Definition at line 134 of file range3f.h.

bool GfRange3f::Contains ( const GfRange3f & range ) const

inline

Returns true if the range is located entirely inside the range. As with all operations of this type, the ranges are assumed to include their extrema.

Definition at line 143 of file range3f.h.

void GfRange3f::ExtendBy ( const GfVec3f & point )

inline

Modifies the range if necessary to surround the given value.

Deprecated:: Use UnionWith() instead.

Definition at line 126 of file range3f.h.

void GfRange3f::ExtendBy ( const GfRange3f & range )
