Detailed Description

A single unit of interpolation.

The begin and end times are interpolated over the lifetime of the particle, thus have the range of [0,1]. Each segment also has a function associated with it.

Member Function Documentation

◆ get_function()

TypedReferenceCount * ColorInterpolationSegment::get_function ( ) const
inline

Returns a reference to the function object corresponding to this segment.

Definition at line 110 of file colorInterpolationManager.I.

◆ get_id()

int ColorInterpolationSegment::get_id ( ) const
inline

Returns the id assigned to this segment by the manager that created it.

Definition at line 157 of file colorInterpolationManager.I.

◆ get_time_begin()

PN_stdfloat ColorInterpolationSegment::get_time_begin ( ) const
inline

Returns the point in the particle's lifetime at which this segment begins its effect.

Referenced by ColorInterpolationManager::generateColor().

◆ interpolateColor()

LColor ColorInterpolationSegment::interpolateColor ( const PN_stdfloat t) const
