Object Detection (Composition by gtoledo3)
This composition shows an object detection routine that's enabled by using an offscreen texture to store color values. I was inspired to whip up this composition after looking at the title and initial picture of an article at Lighthouse3D...but I haven't read the article yet! It's informed by a bunch of stuff I've been doing with id'ing moving objects with openCL; a simple version, if you will. It was a challenge to myself to reproduce the setup from the picture and title before reading the article. Also, due credit of influence to Xiang Bai, and Jamie Shotton for having written good material on id-ing objects, that make this sort of ultra-obvious if you've read their work, as well as the earlier work of many others. It's also pretty darn apparent after doing any math involving normal calc, or coordinate masking, imo, so credit to whoever invented that, and stuff like the ...triangle :) Limited to 10.6 because of the employment of some interaction patches. Keep source texture and rendering destination square for this example. |
