Detailed Description

Extension of PointSet 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. SoMarkerSet uses the coordinates in order, starting with the coordinate at startIndex. The number of coordinates to use (the number of markers in the set) is specified by the numPoints field. The default value of this field is -1, which means to use all the coordinates, so it may not be necessary to explicitly set this 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 points (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.

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.

Shape Antialiasing type is SoShape::POINTS.

Note that SoMarkerSet does not cast a shadow (SoShadowGroup).

The following markers are defined by default:

FILE FORMAT/DEFAULT

MarkerSet {

markerIndex	0
markerScale	1
markerGlobalScale	1
vertexProperty	NULL
startIndex	0
numPoints	-1

}

ACTION BEHAVIOR

SoGLRenderAction
Draws markers based on the current coordinates.

SoGetPrimitiveCountAction
Increments the image count by 1 for each marker in the marker set.

static

Add a new colored marker with index markerIndex .

If the marker exists, it is replaced. size is the size of the marker in pixels. bytes is the marker bitmap. orderedRGBA is an array of per-pixel color values to apply to the marker. The bitmap is arranged row by row from left to right and top to bottom (according to the parameter isUpToDown ). Each byte in the bitmap corresponds to eight pixels. Each value in orderedRGBA corresponds to one pixel. Open Inventor makes a copy of the bitmap and color values.

isLSBFirst : If TRUE, bits are ordered within a byte from least significant to most significant; otherwise the first bit in each byte is the most significant one. 8 isUpToDown : If TRUE, marker bitmap and color array are described from top to bottom (bytes[0] is the left top corner of the bitmap), otherwise from bottom to top (bytes[0] is the bottom left corner).

Member Data Documentation

markerGlobalScale

SoSFFloat SoMarkerSet::markerGlobalScale

Specifies a global scale factor applied to all markers.

Default is 1. This scale factor is applied in addition to the individual scale factors (if any) specified in the markerScale field.

Supported only when using shader implementation (this is the default).

NOTE: field available since Open Inventor 9.3

Definition at line 199 of file SoMarkerSet.h.

markerIndex

SoMFInt32 SoMarkerSet::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.

Note: This is an integer valued field. When writing an application you can use enum values to set the field. However in a .iv file you can only use integer values.
For example, you cannot write:

MarkerSet {
  markerIndex DIAMOND_FILLED_9_9
}

You must write:

MarkerSet {
  markerIndex 82
}

Definition at line 174 of file SoMarkerSet.h.

markerScale

SoMFFloat SoMarkerSet::markerScale

Specifies the scale factor applied to each marker.

Default is 1.
You can specify fewer scale values than the number of markers to be drawn. In this case the "missing" values are looped from the first scale value each necessary time. You can also specify a scale factor to be applied to every marker in the set using the field markerGlobalScale.

Supported only when using shader implementation (this is the default).

NOTE: field available since Open Inventor 9.3
