A python module that builds, modifies, visualizes, and converts 3D LUTs from popular .cube and .3dl formats. The end goal for this module is to remove the obfuscation from proprietary LUT formats and provide a way to programmatically manipulate LUTs.
pip install pylut
And to upgrade:
pip uninstall pylut
pip install pylut
Very mediocre docs viewable at: http://pythonhosted.org/pylut/
The idea is that the modifications to a LUT object are non-volatile, meaning that every modification method returns a new LUT object rather than changing the existing object. All sorts of great things can happen!
from pylut import *
lut = LUT.FromLustre3DLFile("/path/to/file.3dl")
lut2 = LUT.FromLustre3DLFile("/path/to/file2.3dl")
print lut.ColorAtLatticePoint(1,2,1)
print lut.ColorAtInterpolatedLatticePoint(1.3,1.5,1.2)
print lut.ColorFromColor(Color(.002,.5,.2344))
print lut.ColorFromColor(Color.FromRGBInteger(14, 1000, 30, bitdepth = 10))
lut3 = lut.CombineWithLUT(lut2)
lut3 *= .5
lut3 -= LUT.FromIdentity(lut3.cubeSize)
lut3 = lut3.ClampColor(Color(0,0,.2),Color(0,0,.4))
lut3 = lut3.Resize(33)
lut3.ToNuke3DLFile("/path/to/destination.3dl")I also have a terrible CLI inside the bin folder.
Example:
pylut some_lut.3dl --resize 17 --convert RCUBE
In order to run
lut.Plot()
You need to either be running OSX or have PyQt4 or PyGTK installed in order to visualize the cube.
