Detailed Description

Basic type: 1-dimensional floating point range.

This class represents a 1-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]

Definition at line 62 of file range1f.h.

Member Typedef Documentation

typedef float MinMaxType

Helper typedef.

Constructor & Destructor Documentation

GfRange1f ( )

inline

The default constructor creates an empty range.

Definition at line 80 of file range1f.h.

GfRange1f	(	float	min,
		float	max
	)

inline

This constructor initializes the minimum and maximum points.

Definition at line 85 of file range1f.h.

Member Function Documentation

bool Contains ( float 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 128 of file range1f.h.

bool Contains ( const GfRange1f & 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 135 of file range1f.h.

void ExtendBy ( float point )

inline

Modifies the range if necessary to surround the given value.

Deprecated:: Use UnionWith() instead.

Definition at line 120 of file range1f.h.

void ExtendBy ( const GfRange1f & range )

inline

Modifies the range if necessary to surround the given range.

Deprecated:: Use UnionWith() instead.
