The marketplace scenario.

Select frames of a tarantula climbing onto a vertical wall. Green dots show the intersection bounds of the rudimentary sensing mechanism, used to judge the proximity and relative angle of objects in the creature's path.

Key poses of finger crossover while playing scales. The first row shows a key frame of the thumb crossing over the middle finger while playing the C-major scale, and the second row shows a key frame of the thumb crossing over the ring finger while playing the D-major scale, both from three perspectives. Note that the ring/middle finger firmly presses down the keys, the fingers avoid collisions with black keys in C-major, the wrist maintains a natural rotation, and the thumb is positioned well on the key to play it after crossing over.

A sample input source images (A and A ′ ) along with the target input images (B) with the result output (B ′ ) produced using techniques presented in .

The endoscope (green) inside the nasal cavity during simulation of transnasal surgery. In the larger image, some interior structures were made visible. The anatomy is complex and challenging for computation of tissue–tool interaction.
