Visible (album)

Visible was an album by Canadian progressive rock band CANO, released in 1985.

It was the band's final studio album. Marcel Aymar, David Burt, Michel Dasti and Michel Kendell were joined on Visible by Ben Mink replacing Wasyl Kohut, who died of a brain aneurysm, and Mary Lu Zahalan replacing Rachel Paiement, who had moved to the west coast and married Jim Vallance.

The album was strong and revitalized the band briefly. It included "Fond d'une bouteille", which was the French version of a song recorded on the Camouflage album, and "L'eloueze" which was written in Aymar's native Acadian dialect, and most poignantly "J'ai bien vécu", a tribute to band founder André Paiement, who committed suicide in 1978.

Visibility (geometry)

Visibility is a mathematical abstraction of the real-life notion of visibility.

Given a set of obstacles in the Euclidean space, two points in the space are said to be visible to each other, if the line segment that joins them does not intersect any obstacles. (In the Earth's atmosphere light follows a slightly curved path that isn't perfectly predictable, complicating the calculation of actual visibility.)

Computation of visibility is among the basic problems in computational geometry and has applications in computer graphics, motion planning, and other areas.
