Detailed Description

VSG extension Extension of IndexedPointSet that draws a small bitmap (symbol) at each 3D location.

This class draws a marker (small image) at each of a set of points located at the coordinates specified by the vertexProperty field (from SoVertexShape) or the current inherited 3D coordinates. For best performance, the vertexProperty field is recommended. The coordinate of each marker is specified by the coordIndex field which indexes into the list of coordinates. The number of markers is the number of values in the coordIndex field.

You specify the marker to be drawn at each point using the field markerIndex, which indexes into the global list of marker definitions. There is a set of pre-defined markers already in the global list. You can add your own marker definitions to this list using the addMarker functions. Marker definitions in the global list can be used by any SoMarkerSet or SoIndexedMarkerSet node. You can specify fewer index values than the number of markers to be drawn (the number of coordinates). In this case the node will cycle through the provided index values as many times as necessary. If all the markers in the set will use the same definition it is only necessary to set the first value in markerIndex.

You can specify a scale factor (> 0) for each marker using the field markerScale. You can specify fewer scale values than the number of markers to be drawn, but in this case the "missing" values are assumed to be 1. You can also specify a scale factor to be applied to every marker in the set using the field markerGlobalScale. This scale factor is applied in addition to the individual scale factor (if any).

A marker is an image defined by a bitmap and optional color values. If no color values are given then image pixels corresponding to "1" bits are drawn using the current material color (see SoMaterial) and pixels corresponding to "0" bits are not drawn (whatever is behind the marker shows through). If color values are given then each pixel in the image is assigned an RGBA value.

The coordinates of the markers are transformed by the current cumulative transformation.

Lighting is not applied to markers (i.e., they are rendered with light model BASE_COLOR) unless the application explicitly sets normal vectors using SoVertexProperty or SoNormal.

Automatic simplification (by skipping points) is controlled by the SoComplexity field value. Only values < 0.5 have any effect.

Note that custom markers defined with addMarker are not automatically saved in the Open Inventor file when an SoWriteAction is applied to the scene graph (and therefore are not defined if the scene graph is reloaded). To save marker definitions in an Open Inventor file use the SoMarker node.

Depending on the current material and normal binding values, the materials and normals for the vertices may be accessed in order or indexed. If they are indexed, the materialIndex and normalIndex fields are used. Treatment of the current material and normal binding is as follows: PER_PART, PER_FACE, and PER_VERTEX bindings bind one material or normal to each point. The default material binding is OVERALL. The default normal binding is PER_VERTEX.

Limitations:

  • Since Open Inventor 9.3, markers are rendered using a high performance shader implementation by default. However the shader implementation requires support for the OpenGL geometry shader (GL_ARB_geometry_shader4) and texture array (GL_EXT_texture_array) features (or the equivalent extensions). If necessary markers will still be rendered, but using the previous drawPixels() implementation which is slower.
  • SoIndexedMarkerSet does not cast or receive shadows (see SoShadowGroup).

Shape Antialiasing type is SoShape::POINTS.

The following markers are defined by default:

◆ markerGlobalScale

SoSFFloat SoIndexedMarkerSet::markerGlobalScale

Specifies a global scale factor applied to all markers.

Default is 1. This scale factor is applied in addition to the individual scale factor (markerScale).

Supported only when using shader implementation.

Definition at line 180 of file SoIndexedMarkerSet.h.

◆ markerIndex

SoMFInt32 SoIndexedMarkerSet::markerIndex

Specifies the marker index (type of marker) for each marker.

Default is 0. Predefined markers are in enum MarkerType. You can specify fewer index values than the number of markers to be drawn (the number of coordinates). In this case the node will cycle through the provided index values as many times as necessary. For example, if all the markers in the set will use the same definition it is only necessary to set the first value in markerIndex.
