Global Viewpoint Mode
The Global Viewpoint Mode parameter defines a 3-D space and the Viewpoint Position
parameters modify your viewing location with the defined 3-D space. Each Viewpoint Mode uses
three values to specify a viewpoint in space. This point in space is specified by the horizontal
angle, vertical angle, and zoom.
Within any 3-D space, you can choose the viewpoint target as:
• Center of 3-D space
• Center of Object 1
• Center of Object 2
• Center of Object 3
Default DMX Value: 0 = Perspective view, Spherical Coordinates with the focus at the center
of the 3-D space.
Perspective View, Spherical Coordinates
This Viewpoint mode creates a 3-D space with a perspective view of a 3-D space. Viewpoints are
located in terms of X, Y and Z positions located on a sphere surrounding the image.
Perspective View, Cartesian Coordinates
This Viewpoint mode parameter creates a 3-D space with a perspective view. Viewpoints are
located in terms of rectangular X, Y and Z positions describing a location in this space.
Orthogonal View, Cartesian Coordinates
This Viewpoint mode creates a 3-D space without perspective. Viewpoint are located in terms of
rectangular X, Y and Z positions describing a location in this space. In this case, the composite
image is always flat.
Global Viewpoint set with X, Y, and Z
positions all equal to zero. Output displayed with global
viewpoint shown at left.
