BlackTrax Zones
Three-dimensional areas called Zones, can be drawn inside the virtual representation of the Space
in BTWYSIWYG. Zones are an incorporeal volume and can only be viewed in BTWYSIWYG, but if created,
exists simultaneously in the virtual and physical Space. Zones are available in rectangular, cylindrical
and spherical shapes of any size.
BlackTrax has a number of preset interaction between Zones and fixtures, which can be accessed in the
Chapter section in BlackTrax. For more information see To enable a Zone for a Fixture.
