public class Magnifier
extends SoTranslate2Dragger

(Preview Feature) Shape node to display a magnified view of a region of the screen.

Preview Feature means this class is fully supported and can be used in Open Inventor applications. Being tagged as a Preview Feature just means that the implementation is still subject to API changes and adjustments based on feedback from early adopters. Please be also aware that source compatibility might be broken regardless of the Open Inventor compatibility changes policy due to our commitment to bring needed changes to be sure the specifications of this Preview Feature match the expectations of our customers.

This node displays a circular magnified (zoomed in) view of the screen region under the center of the circle. The magnifier is an SoTranslate2Dragger so the user can click and drag to move it around the screen.

Limitations:

• Can only be used in a "2D" viewing environment using an SoOrthographicCamera.
  For example viewing a single slice of a medical volume.
• Can only be used with the default camera orientation (looking toward -Z).

File format/default:

Field Detail

sceneToMagnify

public SoSFNode sceneToMagnify

Specifies the root node of the scene that will be magnified. Default is null.

magnifierColor

public SoSFColor magnifierColor

Specifies the color of the border around the magnifier. Default is 0,0.6,0 (green).

magnifierFactor

public SoSFFloat magnifierFactor

Specifies the magnification factor. Default is 50. Technically speaking this field specifies the value to set in the height field of the magnifier's camera.

Method Detail

getRenderEngineMode

public SoNode.RenderModes getRenderEngineMode()

Description copied from class: SoNode

Returns the supported Render engine mode.

For custom node, this method returns by default SoNode.RenderModes.OIV_UNKNOWN_RENDERING_MODE, override this method to specify the Render engine mode supported by your custom node.

Overrides:

getRenderEngineMode in class SoNode

Returns:

the supported Render engine mode for this node.
