Wire multiple Camera objects into this node’s input, then set or animate the Switch Camera parameter to control which camera’s view the switcher node passes through. Use this switcher as the "camera" for a render node to render the switches.
This object acts like a regular Houdini camera, except that it gets all of its parameters (including transforms) from the input camera. This node has its own rotoscoping options.
Determines which camera to view through - All of the transform and viewing - parameters of the input camera are used.
Whether or not this object is displayed. Turn on the checkbox to have Houdini use this parameter, then set the value to 0 to hide the object, or 1 to show the object. If the checkbox is off, Houdini ignores the value. To see the object in the viewport you must fist create a geometry for viewing. To do this dive into the switcher node and add a geometry such a a sphere. You will now be able to see the active camera with a sphere around it.
Set Wireframe Color
Use the specified wireframe color
The display color of the object
Viewport Selecting Enabled
Object is capable of being picked in the viewport.
Script to run when the object is picked in the viewport. See select scripts .
Cache Object Transform
Caches object transforms once Houdini calculates them. This is especially useful for objects whose world space position is expensive to calculate (such as Sticky objects), and objects at the end of long parenting chains (such as Bones). This option is turned on by default for Sticky and Bone objects.
See the OBJ Caching section of the Houdini Preferences window for how to control the size of the object transform cache.
Override Camera Resolution
Override the camera resolution used.
How to override the camera resolution. A scale factor may be chosen or if set to User Specified Resolution, the values in the Resolution parameter below is used.
If Resolution Scale is set to User Specified Resolution, then these values are used to override the camera resolution. Standard presets are available via the pull down menu to the right of the parameter.
Pixel Aspect Ratio
The pixel aspect ratio represents the width of a pixel divided by the height of a pixel. It is not the aspect ratio of the image (which is determined by the resolution of the image). This parameter does not affect rendering, it is only used to change how images are displayed, by stretching the pixels by this factor.
In this example, we demonstrate how a switcher node can be used to switch the view between two cameras and then used by the render node to output the scene.
The following examples include this node.
