Detailed Description

Property node that defines a color mapping with constant color in each interval.

This node specifies a color mapping defined by a set of N
scalar values (thus N-1 intervals) and N-1 colors representing the constant color used for values located in each interval. Thus, for a given value v, Vk <= v < Vk+1, the associated color is Ck.

Notes:

• The number of colors must be exactly one less than the number of scalars.
  
• If either the number of scalars or the number of colors is zero, the color mapping is ignored.
• Values less than the first scalar are assigned the first color.
• Values greater than the last value are assigned the last color.

Member Data Documentation

colors

SoMFVec4f MoLevelColorMapping::colors

Contains a set of N-1 color values defining the constant color of each level.

Each color consists of R, G, B and A values in the range 0..1. Default is empty.

Definition at line 99 of file MoLevelColorMapping.h.

maxThresholdColor

SoSFVec4f MoLevelColorMapping::maxThresholdColor

Max Threshold color (R, G, B and A values in the range 0..1).

Default is transparent black (0,0,0,0).

Definition at line 133 of file MoLevelColorMapping.h.

maxThresholdEnable

SoSFBool MoLevelColorMapping::maxThresholdEnable

Max Threshold enable flag.

When TRUE, values higher than maxThresholdValue are displayed using the maxThresholdColor. Default is FALSE.

Definition at line 123 of file MoLevelColorMapping.h.

maxThresholdValue

Max Threshold value.

Default is 0.

Definition at line 128 of file MoLevelColorMapping.h.

minThresholdColor

Default is transparent black (0,0,0,0).

Definition at line 116 of file MoLevelColorMapping.h.

minThresholdEnable

SoSFBool MoLevelColorMapping::minThresholdEnable

Min Threshold enable flag.

When TRUE, values lower than minThresholdValue are displayed using the minThresholdColor. Default is FALSE.

Definition at line 106 of file MoLevelColorMapping.h.

minThresholdValue

SoSFFloat MoLevelColorMapping::minThresholdValue

Min Threshold value.

Default is 0.

Definition at line 111 of file MoLevelColorMapping.h.

values

SoMFFloat MoLevelColorMapping::values
