# ViewerObjectSettings

Adjusts how objects are displayed in the Viewer tab.

Connection Type | Connection Name | Function
Input | in | The object whose display you want to modify in the Viewer tab.

Control (UI) | Default Value | Function
CEL | N/A | The scene graph locations are specified using the Collection Expression Language (CEL). The CEL parameter options are available by clicking Add Statements. For more information, refer to the CEL Reference document found on the documentation HTML page (accessed through Help > Documentation) or the CEL Statement Widget Type in Common Parameter Widgets.
drawOptions
hide | No | Sets whether the object should be hidden in the Viewer.
fill | inherit | Sets how the object is displayed, as: • points - display the object using points at the vertices or control points. • wireframe - display the object using wireframe mode. • solid - display the object as a solid. If the display style for the object uses a 3D lighting model, then display the object using that lighting model, whereas if the Viewer tab’s display style is points or wireframe, display the object using a single solid color. • inherit - no change to the object’s display style, use the default.
light | inherit | Sets the lighting model for the object. This setting doesn’t influence the object when it is drawn using wireframe or points. You can set it to: • default - uses the simple shaded lighting model. • shaded - uses the viewer shader assigned to the object (or the default viewer shader if one isn’t assigned). • inherit - don’t override the Viewer tab display style.
smoothing | inherit | When the objects referenced by the CEL statement are being displayed as points or lines, this parameter sets whether they should be anti-aliased. The options are: • off - no anti-aliasing. • lines - when displayed as a wireframe, the objects are anti-aliased. • points - when displayed using points, the objects are anti-aliased. • both - when displayed as a wireframe or using points, the objects are anti-aliased. • inherit - no object specific override, use the current default.
windingOrder | inherit | Sets whether the object has a clockwise or counterclockwise winding order. The winding order determines which direction is considered out from an object and which direction is in.
pointSize | 4 | Sets the size of the points when the object is rendered as a series of points.
color | 0.4, 0.4, 0.4 | Sets the default draw color. For more information, refer to the Color Widget Type in the Common Parameter Widgets.
faceCulling | inherit | Allows geometry in the Hydra Viewer to be rendered without culling faces. • back - cull back-facing faces • front - cull front-facing faces • none - don't cull any faces • inherit - inherit the culling style from ancestor locations By default, back-facing faces are culled in the Hydra Viewer. Note: The OSG Viewer does not cull faces.
annotation
text | None | Sets the text to display with the geometry. When empty, no tag is displayed.
color | 0.4, 0.4, 0.4 | Sets the default background color for any annotation text. For more information, refer to the Color Widget Type in the Common Parameter Widgets.
ViewerObjectSettings parameters continued
pickable | Yes | Sets whether the object is pickable or not.

Parameter path For example, dlLightParams.coneAngle Label (optional) For example, Ang Note: If the label is not provided, the parameter's original label will be used.
