Viewer Interactive Bounding Box Warning message. Bounding box management is essential in compositing. This applies for all the compositing application. Compositor should have good knowledge in managing bbox in their workflow. Your script became more efficient and manageable by maintaining bbox as original format. Also, this help nuke to render your script much faster. All the big studios teaching artists, how to manage bbox in their script. Even-though, Experienced artists fails to maintain their bbox when it comes deadline. Every compositor knows how an artist works a deadline’s. This is a common issue across the studio. Came up with this small idea to warn the artist when their bbox goes beyond twice as original format. Bundled this tool with viewer LUT. When the bbox became 2times bigger than original format, Viewer pops warning message interactively. Warning message goes away once the bbox became normal.           default sRGB LUT...

Working with Bounding box. What is bounding-box: The bounding box is described by 4 numbers. The x-y coordinates of the lower-left corner of the image, followed by the x-y coordinates of the upper-right corner of the image. Its really important for every compositing artist to be aware of bounding box. While working with complex shots, setting-up bounding box in a right way will reduce the computing process time while previewing and rendering. Here i am explaining how to manage bounding box inside Nuke on efficient way. Each shapes have their own bbox. When its come together ( merging in compositing B+A = B or A) Its create a new bbox. Here is the final result when merging two inputs as one. While compositing different resolution(size) of inputs. Boundingbox scaled up then project size. In this example i used a panorama BG with some tracking information. Defocus node defocus the entire panorama image it will take a long time. Look at the bbox size in t...
