These weeks we worked on doing 3D tracking in scenes to clean out small patches and create 3D Scenes in nuke for implementation.
Some quick things we did beforehand was learning how to change the directions of piping in Nuke to allow ease of viewing when looking at pipes and where things connected.
We first went about learning how to do lens undistort, as we would need to undistort the footage and then afterwards we would need to track the footage. We did a distort and then undistort to get a clean undistorted version.
There is also a way to undistort that is less heavy then the lens distortion node, but is also a lot more complex.
We learned about using scanline render and using 3D objects in the 3D View of uke and adding textures to these objects.
Afterwards we looked at making complex 3D scenes, these wouldn’t be to replace Maya but would be used to just make simpler things to then speed up smaller things instead of re-rendering.
We first went about creating a track and giving the scene some treatment, this would help with getting the tracking of this scene done properly.
We then used the Camera Tracker node to get a proper track and create point clouds for our 3D Scene.
I then made a mask of places i didn’t want to track, tracked the shot and had a decent camera solve.
We then learned about using our points clouds and building geometry around said points clouds to get a decent scale of the scene. We also learned about using the modelbuilder in the 3D scene
We stopped and continued this the next week as we were having some small issues.
In the next class we refined what we were doing, got a more accurate track, tracked some geometry properly using the model builder, and implemented some patches onto the geo.
These would be some of the fundamental ways in which i would do some cleanup regarding the Crypt project.
