The Overshoot control effectively turns the spotlight into a hybrid between an Omni light and a spotlight. With Overshoot set, the spotlight casts light in all directions as an Omni light does but still casts shadows or projections as other spotlights do. The shadows and projections are limited to the falloff region: outside the cone of the spotlight, Overshoot casts light but does not cast shadows or projections. Overshoot is useful when you want to light a large area but need to cast shadows in only a small part of that area. Set the falloff to include the area where shadows must appear, and then turn on Overshoot to light the rest of the scene. This technique can reduce the size of shadow maps and thereby improve rendering speed. PAL PAL (Phase Alternate Line) is the video standard used in most European countries. The frame rate is 25 frames per second (fps) or 50 fields on page 7973 per second, with each field accounting for half the interleaved scan lines on a television screen. Parameter Space NURBS objects have, in addition to their existence in 3D space, a parameter space that includes the array of knot values. NURBS curves have a single U dimension in parameter space. NURBS surfaces have two dimensions, U and V, in parameter space. Parameters Panel The parameters panel, found to the right of the event display on page 7968 in Particle View on page 2811, displays the parameters of any action whose name you click in the depot. The panel uses the same format and editing methods as the command panel in 3ds Max. Display of the parameters panel can be toggled with the Particle View menu command Display > Parameters. 8078 | Glossary
