Science D Visions 3DEqualizer Weta Digital LDPK Nuke Nodes

Dear Friends of 3DE!

It turned out that our new lens distortion models, recently introduced with 3DE4 r1b10, are much more powerful than our "vintage" classic one.

To make them even more powerful, in terms of integration into production pipelines, our friends at Weta Digital developed a Nuke node infrastructure which is based on our lens distortion SDK (LDPK).

The cool thing is, they released their work as open source:

Nuke nodes for 3D Equalizer lens distortion plugin kit


In addition, there is a 3DE4 Python script which allows to create a Nuke 3DE distortion node (.nk), compatible to the currently selected camera (incl. dynamic lens distortion):

Export Nuke Distortion Nodes v1.2


Many thanks to Peter Hillman, Wolfgang Niedermeier and Lee Bramwell!

Cheers,

Rolf

Port by Christian Schnellhammer & Stefan Galleithner


3de4_nuke_distortion_nodes_win64.tar.gz

A binary distribution (.dlls) of Peter Hillman's "LDPK Nuke Nodes" for Windows 64bit.


Christian and Stefan are members of a multidisciplinary image creation freelance collaboration, which combines over a decade of experience in visual effects, software development, design and photography. More infos can be found here.



Instructions:

Files:

- Nuke_6.2v2.bat: a startup script for properly running Nuke 6.2v2 incl. 3DE4's warp nodes
- lensDistortion_3de.dll: actual Nuke plugin which imports 3DE4's lens plugins
- tde4_ldp_anamorphic_deg_6.dll: a plugin which implements distortion model "3DE4 Anamorphic, Degree 6"
- tde4_ldp_classic_3de_mixed.dll: a plugin which implements distortion model "3DE Classic LD Model"
- tde4_ldp_radial_decentered_deg_4.dll: a plugin which implements distortion model "3DE4 Radial - Stadard Degree 4"


Installation:

- copy "lensDistortion_3de.dll" to Nuke's plugin directory

- edit Nuke_6.2v2.bat according to your needs

- env var "LENSMODEL_PATH" should point to the directory where the actual lens distortion model .dlls are located

- add the following lines to menu.py:

# 3de lens distortion
toolbar = nuke.menu("Nodes")
n = toolbar.addMenu("3deLens", "")
n.addCommand("Lens_3de_classic_mixed","nuke.createNode('tde4_ldp_classic_3de_mixed')")
n.addCommand("Lens_3de_anamorphic_deg_6","nuke.createNode('tde4_ldp_anamorphic_deg_6')")
n.addCommand("Lens_3de_radial_decentered_deg_4","nuke.createNode('tde4_ldp_radial_decentered_deg_4')")

- add the following lines to init.py:

# user plugins
nuke.load("lensDistortion_3de.dll")
