16 (Volume 3))

3))
• On the MVE-9000, the method of combiner channel selection is different
from that on the BKDS-9470. See “Combiner Settings” (page 561).
Three-Dimensional Transformations
Transformation is the process of placing a video image in a three-dimensional
DME coordinate space and subjecting it to manipulations such as movement,
rotation, magnification or shrinking.
Three-dimensional coordinate space
Source coordinate space and target coordinate space
Images are placed in one of two types of coordinate space: source coordinate
space and target coordinate space.
• The source coordinate space is a three-dimensional coordinate space with
reference to the image itself. The x- and y-axes are defined parallel to the
plane of the image, and the z-axis is defined perpendicular to the plane of the
image. When you move the image, the coordinate axes also move.
• The target coordinate space is a three-dimensional coordinate space with
reference to the output monitor screen. The x- and y-axes are defined parallel
to the plane of the monitor screen, and the z-axis is defined perpendicular to
the plane of the monitor screen. The coordinates do not move even if the
image moves.
