Fast Random Rotation Matrices
In a previous gem Arvo 91] I described a method for generating random rotation matrices based on random unit quaternions. As Ken Shoemake points out in his gem Shoemake 92], that algorithm was awed in that it did not generate uniformly distributed rotation matrices. For a method based on quaternions that corrects this defect, with only slightly more computation, see his algorithm. In this gem I...
متن کاملFast and Controllable 3D Modelling From Silhouettes
We show how a 3D model of a complex curved object can be easily extracted from a single 2D image. A userdefined silhouette is the key input; and we show that finding the smoothest 3D surface which projects exactly to this silhouette can be expressed as a quadratic optimization, a result which has not previously appeared in the large literature on the shape-from-silhouette problem. For simple mo...
متن کاملLikelihood-enhanced fast rotation functions.
Experiences with the molecular-replacement program Beast have shown that maximum-likelihood rotation targets are more sensitive to the correct orientation than traditional targets. However, this comes at a high computational cost: brute-force rotation searches can take hours or even days of computation time on current desktop computers. Series approximations to the full likelihood target have b...
متن کاملBose-Einstein condensates in fast rotation
In this short review we present our recent results concerning the rotation of atomic Bose-Einstein condensates confined in quadratic or quartic potentials, and give an overview of the field. We first describe the procedure used to set an atomic gas in rotation and briefly discuss the physics of condensates containing a single vortex line. We then address the regime of fast rotation in harmonic ...
متن کاملMeasurement of Fast Rotation by VLSI Circuits
There exist important problems that require the measurement of very fast motion. Common techniques for motion estimation based on sequences of video images usually fail to deliver the correct results for such problems due to the low video rate. We present an analog VLSI based system that determines the motion in real-time. We demonstrate the performance of that system for the case of measuring ...
