| This is an overview of property linking in ParaView. | | This page moved [http://paraview.org/Wiki/Camera_and_Property_Linking here]. |
| | |
| '''There are a few types of links.'''
| |
| * Camera
| |
| * Proxy
| |
| * Property
| |
| | |
| '''Camera Linking'''
| |
| * A camera link links cameras from two render modules together.
| |
| * A change in one, propagates to the other, and vice versa.
| |
| | |
| '''Proxy Linking'''
| |
| * Two proxies can be linked together.
| |
| * If a proxy have any property with the same name as the other proxy, those properties will be linked.
| |
| ** For example:
| |
| *** Two sphere sources will have all of their properties linked.
| |
| *** A sphere source and a cylinder source will have only Radius and Center linked.
| |
| *** The planes of two clip filters can be linked.
| |
| | |
| '''Property Linking'''
| |
| * Two properties of the same type can be linked.
| |
| ** For example:
| |
| *** A sphere's Phi Resolution and Theta Resolution can be linked.
| |
| *** A cylinder's radius and a sphere's radius can be linked.
| |
| *** A cylinder's radius cannot be linked with a sphere's center.
| |
| | |
| '''Creating links in ParaView'''
| |
| * Quick view links can be created by right clicking in a view and selecting "Link Views..." A popup window is presented with the ability to name the link, and cancel. The link is created when the user clicks on another view.
| |
| * Tools -> Manage Links... is a place to manage all types of links.
| |
| ** Links can be added/edited/removed.
| |
| ** When adding/editing a link, property or object types can be chosen. Views can be selected under the object type.
| |
| | |
| '''Implementation Overview'''
| |
| * Server Manager
| |
| ** vtkSMCameraLink, vtkSMPropertyLink, vtkSMProxyLink share a common vtkSMLink base class.
| |
| ** vtkSM*Link classes support bi-directional links, with multiple "inputs" and multiple "outputs".
| |
| ** If an "input" changes, the values are copied to the "outputs."
| |
| * GUI side
| |
| ** All links are bi-directional.
| |
| ** All links are between only two objects. In other words, the vtkSM*Link objects have two inputs and two outputs. If it were not bi-directional, it would be one input and one output.
| |
| ** Camera linking is called View linking.
