## colors fragments by z-value.
## This is useful for coloring surface plots by height.
## This shader uses a uniform called "colorMap" to determine how to map the colors:
## red = pow(z * colorMap[0] + colorMap[1], colorMap[2])
## green = pow(z * colorMap[3] + colorMap[4], colorMap[5])
## blue = pow(z * colorMap[6] + colorMap[7], colorMap[8])
## red = pow(colorMap[0]*(z + colorMap[1]), colorMap[2])
## green = pow(colorMap[3]*(z + colorMap[4]), colorMap[5])
## blue = pow(colorMap[6]*(z + colorMap[7]), colorMap[8])
## (set the values like this: shader['uniformMap'] = array([...])
