Chapter 18 Compositing With the MultiPlane Node 491
Whichever angle is assigned as the renderCamera has the following additional
properties:
• It’s the only angle that can be switched between viewing the software-rendered final
output, and the hardware-rendered preview.
• It’s the only angle with a compare control (in software-rendering mode only).
• The image border ROI (Region of Interest) appears only for the renderCamera angle.
• There are additional keyboard shortcuts available for transforming a camera. For
more information, see “Manipulating the Camera” on page 517.
How the renderCamera Defines Image Output
Even though the renderCamera angle shows the region defined by the camera target’s
ROI, the image data appearing outside of this area is not cropped. Shake’s Infinite
Workspace once again preserves this information for use by downstream nodes
elsewhere in your script.
MultiPlane Viewer Shelf Controls
When you open a MultiPlane node into the Viewer, a group of controls specific to the
MultiPlane node appear in the Viewer shelf. These controls let you toggle the visibility
of various onscreen controls in the Viewer.
Customizing the MultiPlane Default Camera
You can customize the default angles that appear for new MultiPlane nodes.
Use the following declaration within a .h preference file:
DefDefaultMPCamera( Camera(0, "v4.0", "Front", imageWidth/(2*settings-
>yPixelUnit), imageHeight/(2*settings->yPixelUnit), 3000, 0, 0, 0,
"XZY", 0, 0.980, 0.735, 2, "Fill", 0, 0, 0, "default", xFilter, 0, .5,
0 ) );
Button Description
Point Cloud Display Displays/hides the individual locator points that display the
imported point cloud data. Displaying this data can make it easier
to align layers with the approximate locations of features that
were tracked. Hiding this data can make it easier to manipulate
the individual layers.
For more information on locator points, see “V
iewing and Using
Locator Points” on page 498.
XYZ Angle Displays/Hides the X, Y, and Z angle controls, which can make it
easier to reposition objects without accidentally rotating them. A
third option is available by clicking and holding down the mouse
button to reveal a pop-up menu.
