Kinect 를 이용한 3D 모델링 기술

http://3rdeyeanimation.blogspot.com/2011/03/cursor.html


Kinect 를 이용해서 가상의 3d 공간에서 mesh 모델링을 하는 기술을 선보입니다. 이렇게 모델링한 데이터를 3dsMax 로 바로 가져올 수 있습니다.




a simple mesh modeller that uses KINECTs depth perception and homemade data gloves for a more real world oriented user interaction in virtual 3d space.
realized only with open source software
PURE DATA, GEM, OpenNI, UBUNTU.

Real-time Metropolis Light Transport on the GPU

http://www.youtube.com/watch?v=c7wTaW46gzA   ERPT vs PT (standard Path tracing)

ERPT on the left, standard path tracing (PT) on the right. Light is coming in from a narrow opening, a scenario in which PT has a hard time to find light paths and converge, because it randomly samples the environment. ERPT shares properties with MLT: once it finds an important light path, it will sample nearby paths via small mutations of the found light path, so convergence is much faster.

Kelemen-MLT after 10 seconds of rendering at 1280x720 on a single GTX 470The beautiful caustics are possible due to bidirectional path tracing+MLT and are much more difficult to obtain with standard path tracing.

Kinect Integration for Real-Time Markerless Motion Capture - Organic Motion R&D Preview


Kinect 센서와 몇 대의 웹캠, 그리고 자사의 Organic Motion 트래킹 소프트웨어만으로 매우 정교한 마커없는 모션 캡쳐를 가능하게 한다고 합니다.
