Go Behind The Scenes with ITs Art

ITs Art has an a great collections of behind the scenes of some of the Best Visual Effects Work from Studios around the world. Check it out at – http://www.itsartmag.com/features/verybestofvfx/


The Quick and Dirty way to Get the Track You need

At facilities Sometimes a comprensive tools set is provided for the job that is at hand, for example they may only have moca for after effects and Nuke 6 instead of X leaving planar tracking out of the picture in times where you may desperatly need it.

Or You may want to take avantage of PF Tracks 2011-2012 Robust user Tracks for a rotation and Skew heavy shot.

Well here are two tools I use, that exist in the cloud and are ready for you right now.

Quick Tip: Nuke and Dots

Organizing your Nuke script can be tricky, allot of things overlap input if you don’t plan your script out right.

If your not familiar with the “.” key I would suggest you make it your new best friend, Open up nuke hover over the Node Graph and Hit and hold it.

nuke dots

Before your eyes the Round Node path connectors called “dots” will Manifest over and over again, you might not need this many. ..But start your First Read Node out with 3 of them to start out with.

To add additional dots to a stream of nodes hold down the option key to have the mid points of the connections light up, then select where you want it to go.

 


Interior Panoramas

Lets face it, blueprints to every piece of architecture you’ll come across isn’t always realistic, or practical.This leads to finding the “unofficial” ways to transform what we see infront of us into an Orthographic image. Since I have a camera on me more than measuring tape as does i’m sure of all of us these days, Making a Photo Stich is a great solution.

A few problem arise when you go about to do this,
Parallax. What normally isn’t a problem when you capture that wide mountain vista in your vacation photos, suddenly becomes a jarring problem. From one Photo to the next, Objects closer to the camera will jump further and further away from shot to shot. So far in fact that stitching algorithms such as Photoshop, Throw up their hands in defeat, as they cant figure out whats going on from the what is the background of the photo to the foreground.

Photoshop isnt the sharpest tool in the draw, more like the a paraplegic kid on the playground who has fallen face first in the mud as he or she hopelessly shouts no no I can do it…I dont want anyones help.

For a solution to deal with this issue, a different program is required.
Thanks to thouse hardworking open source Enthousiasts and Developers we have Hugin. This Affectionally named Program, Knows the ins and outs of photo stitching that allows human input at the heart of the matter. Now Tutorials for this programed are over documented on its own web site but, for this situation, how you shoot matters allot.

http://hugin.sourceforge.net/

Always keep a Equidistance from the furthest Plane of Parallax, Shoot in Straight lines, literally. Trace out a horizontal line and folow it to a T. This will keep the what could be a difficult solve easier.

(only for refence panos) Try take picture from the closet point to you to the next, the goal is to get the stitched image to be as orthographic (flat/without perspective)  as we can make it, this means barriers that come strait at you should be photographed head on, and as little of their sides photographed as posible.

Once you got that down, Get the Photos imported and loaded.
only Aline similarities of the user features to the further plain of parallax, or the Plain you want to aline too. This will Create the the constancy of the stich through out the Solve that will give you the best results.


Baking out Projection in Nuke

Anyone who is a nuke Artist loves projections. Infact when you are a nuke artist you start getting the urge to project everything onto Geometry…and why not its alot better than multi plaining in Shake.  But this wonderful tool has a few limitations. You cant use multiple projection shaders and any roto item post element in the node tree and the projection maps incorrectly.  Sooo Can we Bake out what we project on geometry to UVs? Absolutely,  Notice how the render Node says Obj/Scn, you probably have used the Scn Part but today we are going to attach it to the Obj part.  Go ahead and link the input to the Geometry node you want to bake out. Next in the Render node, under Scanline go to the drop down menu Projection and change it to UV.

If your viewer is attached up to the Node tree to see the rendered results you’ll see the UV Texture rendered out and ready for you to write it out to a file.  (Note Cards and other Nuke Geometry UVs are already laid out, if you havnt laid out your UVS or your Generating  poissonmesh you’ll need to Set your UVS in an external 3d Program. )


Keep OS X Windows Floating

As much as I love the way the OSX Render engines Quarz floats windows on top very not every program has this built in. For Example Quicktime Pro and Quicktime X both lack this functionality.

float above

The solution to this problem was a Great and Light weight app called Afloat. Afloat nests its self with in the default WIndow menu of the operating system. This wont apply to all programs, but will for most, including Web browsers and Media players.
