cee::vis::ColorTableFactory

class ColorTableFactory

Factory functions for creating color tables based on a predefined number of color schemes.

These color tables can then be used to configure scalar mappers, which will again be used to setup a color legend (e.g. OverlayColorLegendContinuousDomain).

Public Types

enum ColorTable

The predefined color schemes supported by the color table factory.

Values:

enumerator NORMAL: The standard color map for scalar mapping in EnvisionDesktop. Following the color spectra, but starting on blue and ending on red.

enumerator BLACK_WHITE: Black to while color map.

enumerator BLUE_RED: Blue to red color map.

enumerator BLUE_GREEN: Blue to green color map.

enumerator YELLOW_RED: Yellow to red color map.

enumerator GREEN_YELLOW_RED: A map from Green through yellow ending up in red.

enumerator RED_YELLOW: A red to yellow color map.

enumerator THERMAL_1: A map suitable for thermal scalars.

enumerator THERMAL_2: A map suitable for thermal scalars.

enumerator THERMAL_3: A map suitable for thermal scalars.

enumerator METAL_CASTING: A map suitable for metal casting.

enumerator VIRIDIS: Purple to yellow color map.

Public Static Functions

static std::vector<Color3f> colorTableArray(ColorTable colorTable, size_t colorCount)

Returns an array of colors created from the given color scheme.

The returned array will have colorCount number of values

static std::vector<Color3f> interpolateColorArray(const std::vector<Color3f> &colorArray, size_t targetColorCount)

Interpolates a graded color table with the given number of colors (targetColorCount) based on the input colors (colorArray).

This is useful for creating gradient/continuous style color maps based on two or more colors.
