Remarks

This is a subclass of OIV.Inventor.Nodes.SoSeparator that redraws itself in a different color when the cursor is over the contents of the separator.

The redraw happens for that separator only and not the entire window (redraw along the handle event pick path) and in the front buffer, to efficiently track the mouse motion. The highlighted redraw overrides the emissive and/or diffuse color of the subgraph based on the field values in this node.

NOTE: when using OIV.Inventor.Nodes.SoLightModel.Models.BASE_COLOR (to turn lighting off) only the diffuse color will be used to render objects, so EMISSIVE_DIFFUSE must be used for this node to have any effect.

Limitations:

  • When using a SceneExaminer, subgraph can remain highlighted after switching from selection mode to viewing mode.

  • When using an examiner viewer or a SceneExaminer, subgraph can remain unhighlighted when switching from viewing mode to selection mode until the mouse is moved.

  • The SceneOrbiter does not have such limitation.

    To override the default mode (off), set environment variable IV_ALLOW_LOCATE_HIGHLIGHT to 1. This will allow locate highlighting to happen by default.

FILE FORMAT/DEFAULT

}

ACTION BEHAVIOR

OIV.Inventor.Actions.SoHandleEventAction Checks to see if the cursor moves onto or off of the contents of the separator, and redraws appropriately (if OIV.Inventor.Nodes.SoLocateHighlight.mode is AUTO), otherwise traverses as a normal separator.

OIV.Inventor.Actions.SoGLRenderAction Redraws either highlighted (if cursor is over the contents of the separator when OIV.Inventor.Nodes.SoLocateHighlight.mode == AUTO or always if OIV.Inventor.Nodes.SoLocateHighlight.mode == ON), otherwise traverses as a normal separator.
