A visleaf, or a leaf, is a type of volume in a map created by the visibility compile tools. When any part of a leaf is visible from any part of the current leaf, the entire contents of that leaf are considered for rendering.
You can view the current leaf in the engine by submitting mat_leafvis 1 to the console. A red wireframe box will be drawn, and will redraw each time a new leaf is entered.
Leaves can also be examined from the desktop with the glview tool.
