Let’s say I have a false-color elevation map, purple for low, then going up through blue, green, yellow, orange, red, and finally
white. Does anybody know a way to convert this into a simple grey scale height map? In other words, black = low, white = high.
Changing the image to greyscale is not sufficient, as the green and yellow areas stand out as higher than the red, due to their
higher luma values. If I have a rectangle with the colors in order, can I analyze that and apply it as a gradient to the rest of
the image? I ask this because most 3D programs I know only accept greyscale height maps as a displacement terrain map, and most
height maps I’m able to get use this false-color format instead…
