Volume Cartographer 2.27.0
|
A lookup table (LUT) is a data structure used to remap raw data values to a new range of data values. Often this is used to false color an image by remapping raw pixel values through a LUT to a new range of RGB color values. This process is also known as color mapping.
Volume Cartographer provides support for linearly remapping images to a number of built-in color maps using the volcart::ApplyLUT functions. The basic process is as follows:
Available color maps include:
Color map | Output range |
---|---|
Magma |
|
Inferno |
|
Plasma |
|
Viridis |
|
BWR |
|
See volcart::ColorMap for a full list of available color maps.
We provide the vc_color_map
utility for remapping arbitrary images to one of our built-in color maps:
Run vc_color_map --help
for more options and information.
