Detailed Description

High level class for color interpolation.

Segments must be added to the manager in order to achieve results using the "add_*****()" functions. Access to these segments is provided but not necessary general use.

const LColor color_b = LColor(0.0f,1.0f,0.0f,1.0f),
const bool  is_modulated = true 
)

Adds a linear segment between two colors to the manager and returns the segment's id as known by the manager.

const LColor color_b = LColor(0.0f,1.0f,0.0f,1.0f),
const PN_stdfloat  period = 1.0f,
const bool  is_modulated = true 
)

Adds a stepwave segment of two colors and a specified period to the manager and returns the segment's id as known by the manager.

int ColorInterpolationManager::add_stepwave ( const PN_stdfloat  time_begin = 0.0f,
const PN_stdfloat  time_end = 1.0f,
const LColor color_a = LColor(1.0f,0.0f,0.0f,1.0f),

const PN_stdfloat  width_a = 0.5f,
const PN_stdfloat  width_b = 0.5f,
const bool  is_modulated = true 
)

Adds a stepwave segment of two colors to the manager and returns the segment's id as known by the manager.

Definition at line 344 of file colorInterpolationManager.cxx.

void ColorInterpolationManager::clear_segment ( const int  seg_id)

Removes the segment of 'id' from the manager.

Definition at line 378 of file colorInterpolationManager.cxx.

Removes all segments from the manager.

Definition at line 396 of file colorInterpolationManager.cxx.

LColor ColorInterpolationManager::generateColor ( const PN_stdfloat  interpolated_time)

For time 'interpolated_time', this returns the additive composite color of all segments that influence that instant in the particle's lifetime.

If no segments cover that time, the manager's default color is returned.

References ColorInterpolationSegment::get_time_begin(), ColorInterpolationSegment::get_time_end(), ColorInterpolationSegment::interpolateColor(), ColorInterpolationSegment::is_enabled(), and ColorInterpolationSegment::is_modulated().

Returns the segment that corresponds to 'seg_id'.

Definition at line 284 of file colorInterpolationManager.I.

Returns a space delimited list of all of the ids in the manager at the time.

Definition at line 302 of file colorInterpolationManager.I.

Sets the color to used if no segments are present.
