Detailed Description

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

This node defines a linear color mapping defined by a set of scalar values and their corresponding colors. For a given value v, Vk <= v <= Vk+1, the associated color c is determined by a linear interpolation between (Vk,Ck) and (Vk+1,Ck+1). Where Vk,Ck is pair number k of the colormap.

Notes:

• The number of colors must be exactly the same as 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

SoMFVec4f MoLinearColorMapping::colors

Contains a set of N colors defining the color at each scalar value.

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

SoSFVec4f MoLinearColorMapping::maxThresholdColor

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

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

SoSFBool MoLinearColorMapping::maxThresholdEnable

Max Threshold enable flag.

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

SoSFFloat MoLinearColorMapping::maxThresholdValue

Max Threshold value.

Default is 0.

SoSFVec4f MoLinearColorMapping::minThresholdColor

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

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

SoSFBool MoLinearColorMapping::minThresholdEnable

Min Threshold enable flag.

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

SoSFFloat MoLinearColorMapping::minThresholdValue

Min Threshold value.

Default is 0.

SoMFFloat MoLinearColorMapping::values

Contains a set of N scalar values defining the levels of the colormap.

Default is empty.
