Magic Sprites - Sprite based refraction and other Sprite Effects

Modern 3d graphics hardware provides a host of capabilities for fast 2d sprite effects. This papers describes an implementation of several fragment shaders that give realistic details to simple sprites. In particular bump mapping, relief mapping, and sprite based refraction have been implemented. Performance and possible future direction is also discussed. CR Categories: I.3.7 [Computer Graphic...

Poem: A Lewis Thomas View of Medicine

Dr Grace Dammann had devoted decades of her life to the compassionate care of AIDS patients in San Francisco, California, when, on May 21, 2008, a head-on vehicle collision on the Golden Gate Bridge nearly took her life. When she not only survived but came out of a coma with all of her mental faculties intact, Grace, her family, and her doctors agreed it was nothing short of a miracle. Her path...

Multi-Frame SPRITE: a method for resolution enhancement of multiple-point SPRITE data.

The Single Point Ramped Imaging with T1 Enhancement (SPRITE) sequence is well suited for the acquisition of magnetic resonance signals from fast relaxing nuclei and from heterogeneous materials. However, it is time inefficient compared to sequences that are based on frequency encoding because only one single point is acquired per excitation. Multiple-point SPRITE (mSPRITE) mitigates this proble...
