The Lens Distortion Plugin Kit (LDPK) is a collection of sources, headers, binaries and documents which help you to develop lens distortion plugins for 3DE4 and compositing systems.

Features

• Better performance (especially for non-dynamic lens distortion)
• More alternatives for handling bounding boxes
• Plugins of the five built-in 3DE4 lens distortion models for Nuke
• Source code and mathematical description for the built-in models
• A tool for creating ST maps
• Python Bindings for the built-in models

The following combinations of Nuke version and platform are supported:

• Linux: Nuke 10.0, 10.5, 11.0, 11.1, 11.2, 11.3, 12.0, 12.1, 12.2
• macOS: Nuke 10.0, 10.5, 11.0, 11.1, 11.2, 11.3, 12.0, 12.1, 12.2
• Windows: Nuke 10.0, 10.5, 11.0, 11.1, 11.2, 11.3, 12.0, 12.1, 12.2

For futher information please see the documentation in folder
$LDPK > doc > cdml > ldpk > html > ldpk.xhtml.

Please note: Nuke 11 comes with a new, build-in lens distortion node. If you wish to use this new node instead of LDPK, then this script might be interesting for you!

Installation Instructions Nuke plugins

1. Extract archive ldpk-2.4.tgz 

2. Goto folder compiled > nuke.

3. Select folders respective to your OS and Nuke version.

4. Copy following files to Nukes plugin folder:

• LD_3DE4_Anamorphic_Degree_6
• LD_3DE4_Anamorphic_Standard_Degree_4
• LD_3DE4_Anamorphic_Rescaled_Degree_4
• LD_3DE4_Radial_Fisheye_Degree_8
• LD_3DE4_Radial_Standard_Degree_4
• LD_3DE_Classic_LD_Model

5. In order to access LDPK directly from Nukes node menu, edit file  menu.py  (also in Nuke folder plugins) by adding the following lines:

nuke.menu("Nodes").addCommand("3DE4/LD_3DE4_Anamorphic_Standard_Degree_4", "nuke.createNode('LD_3DE4_Anamorphic_Standard_Degree_4')")
nuke.menu("Nodes").addCommand("3DE4/LD_3DE4_Anamorphic_Rescaled_Degree_4", "nuke.createNode('LD_3DE4_Anamorphic_Rescaled_Degree_4')")
nuke.menu("Nodes").addCommand("3DE4/LD_3DE4_Anamorphic_Degree_6", "nuke.createNode('LD_3DE4_Anamorphic_Degree_6')")
nuke.menu("Nodes").addCommand("3DE4/LD_3DE4_Radial_Standard_Degree_4", "nuke.createNode('LD_3DE4_Radial_Standard_Degree_4')")
nuke.menu("Nodes").addCommand("3DE4/LD_3DE4_Radial_Fisheye_Degree_8", "nuke.createNode('LD_3DE4_Radial_Fisheye_Degree_8')")
nuke.menu("Nodes").addCommand("3DE4/LD_3DE_Classic_LD_Model", "nuke.createNode('LD_3DE_Classic_LD_Model')")

Installation Instructions 3DE4 Export to Nuke Script

1. In the extracted archive, goto folder $LDPK > 3de4 > python.

2. Copy the following file to 3DE4 folder sys_data > py_scripts:

• export_nuke_LD_3DE4_Lens_Distortion_Node.py
