Webcam-based object recognition

2012-07-12T03:01:34.373Z

Using the color information from a webcam feed to maneuver geometry inside of Rhino. Once again relying heavily on Andy Payne's new vision components in Firefly. The 3D projection techniques (especially the depth) are only approximations right now, tweaked to look right using Galapagos and a little patience. Still working on the math to make it properly accurate....if AR Media can do it, I can too....

The rotation didn't really show up much in this video. Usually works a little better. Also, the red box's form is not derived from the green square. The script does roughly translate the square into Rhino geometry, but I'm only using it as a marker for the webcam to recognize.

Webcam-based viewport control

2012-07-06T06:58:41.446Z

Using a webcam to (loosely) control the perspective viewport in Rhino. This relies heavily on Andy Payne's new vision components in Firefly and also uses Yiannis Chatzikonstantinou's Hoopsnake and the camera control components from Hiroshi Jacobs's Chameleon. The credit for making this possible really goes to them.

Excuse the getup. Until I get money for fancy cameras and Kinects, I'll just have to make do with strapping webcams to my head. =)

Grasshopper Analysis Grid Key

2010-07-16T17:07:19.235Z

The purpose of this definition is to create an analysis grid key that is normal the camera view and displayed over top of other geometry. Definition is still in development so any suggestions and comments are appreciated.
