Acts as a camera but switches between the views from other cameras.
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.
Parameters
Viewing
| Switch Camera | Determines which camera to view through - All of the transform and viewing - parameters of the input camera are used. |
| Display | 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. |
Misc
| Set Wireframe Color | Use the specified wireframe color |
| Wireframe Color | The display color of the object |
| Viewport Selecting Enabled | Object is capable of being picked in viewport. |
| Select Script | 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. |
Output
| Override Camera Resolution | Override the camera resolution used. |
| Resolution Scale | 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. |
| Resolution | 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 | The pixel aspect ratio of the output image. |
Examples
| switchcamera | Load | Launch |
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. | |
