## Detailed Description

The **SoMarkerSet** class displays a set of 2D bitmap markers in 3D.

This node uses the coordinates currently on the state (or in the vertexProperty field) in order. The numPoints field specifies the number of points in the set.

In addition to supplying the user with a set of standard markers to choose from, it is also possible to specify one's own bitmaps for markers.

This node class is an extension versus the original SGI Inventor v2.1 API. In addition to being a Coin extension, it is also present in TGS' Inventor implementation. (Note that TGS's implementation doesn't support the NONE markerIndex value.)

**FILE FORMAT/DEFAULTS:**

```
MarkerSet {
    vertexProperty NULL
    startIndex 0
    numPoints -1
    markerIndex 0
}
```

## Member Enumeration Documentation

### enum SoMarkerSet::MarkerType

Defines the different standard markers.

## Constructor & Destructor Documentation

### SoMarkerSet::SoMarkerSet (void )

Constructor.

### SoMarkerSet::~SoMarkerSet () \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoMarkerSet::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### SoType SoMarkerSet::getTypeId (void ) const \[virtual\]

Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting.

Reimplemented from **SoPointSet**.

### const SoFieldData \*\* SoMarkerSet::getFieldDataPtr (void ) \[static\], \[protected\]

*This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\

 Returns the **SoFieldData** class which holds information about fields in this node.

### const SoFieldData \* SoMarkerSet::getFieldData (void ) const \[protected\], \[virtual\]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from **SoPointSet**.

### void SoMarkerSet::initClass (void ) \[static\]

### void SoMarkerSet::GLRender (SoGLRenderAction \* action) \[virtual\]

Action method for the **SoGLRenderAction**.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.

Reimplemented from **SoPointSet**.

### void SoMarkerSet::getPrimitiveCount (SoGetPrimitiveCountAction \* action) \[virtual\]

Action method for the **SoGetPrimitiveCountAction**.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the *action*.

Nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from **SoPointSet**.

### int SoMarkerSet::getNumDefinedMarkers (void ) \[static\]

Returns the number of defined markers.

### void SoMarkerSet::addMarker (int idx, const SbVec2s & size, const unsigned char \* bytes, SbBool isLSBFirst = TRUE, SbBool isUpToDown = TRUE) \[static\]

Replace the bitmap for the marker at *idx* with the representation given by *size* dimensions with the bitmap data at *bytes*. *isLSBFirst* and *isUpToDown* indicates how the bitmap data is ordered. Does nothing if *markerIndex* is NONE.

Here's a complete usage example which demonstrates how to set up a user specified marker from a character map. Note that the "multi colored" pixmap data is converted to a monochrome bitmap before being passed to **addMarker()** because **addMarker()** supports only bitmaps.

```
const int WIDTH = 18;
const int HEIGHT = 19;
const int BYTEWIDTH = (WIDTH + 7) / 2;
const char coin_marker[WIDTH * HEIGHT + 1] = {
  ".+                "
  "+@.+              "
  " .@#.+            "
  " +$@##.+          "
  "  .%@&##.+        "
  "  +$@&&*##.+      "
  "   .%@&&*=##.+    "
  "   +$@&&&&=-##.+  "
  "    .%@&&&&&-;#&+ "
  "    +$@&&&&&&=#.  "
  "     .%@&&&&*#.   "
  "     +$@&&&&#.    "
  "      .%@&@%@#.   "
  "      +$%@%.$@#.  "
  "       .%%. .$@#. "
  "       +$.   .$>#."
  "        +     .$. "
  "               .  "
  "                  " };
int byteidx = 0;
unsigned char bitmapbytes[BYTEWIDTH * HEIGHT];
for (int h = 0; h < HEIGHT; h++) {
  unsigned char bits = 0;
  for (int w = 0; w < WIDTH; w++) {
    if (coin_marker[(h * WIDTH) + w] != ' ') { bits |= (0x80 >> (w % 8)); }
    if ((((w + 1) % 8) == 0) || (w == WIDTH - 1)) {
      bitmapbytes[byteidx++] = bits;
      bits = 0;
    }
  }
}
int MYAPP_ARROW_IDX = SoMarkerSet::getNumDefinedMarkers(); // add at end
SoMarkerSet::addMarker(MYAPP_ARROW_IDX, SbVec2s(WIDTH, HEIGHT),
                       bitmapbytes, FALSE, TRUE);
```

This will provide you with an index given by MYAPP\_ARROW\_IDX which can be used in **SoMarkerSet::markerIndex** to display the new marker.

### SbBool SoMarkerSet::getMarker (int idx, SbVec2s & size, const unsigned char \*& bytes, SbBool & isLSBFirst) \[static\]

Returns data for marker at *idx* in the *size*, *bytes* and *isLSBFirst* parameters.

If no marker is defined for given *idx*, or **SoMarkerSet::markerIndex** is NONE (not removable), FALSE is returned. If everything is OK, TRUE is returned.

### SbBool SoMarkerSet::removeMarker (int idx) \[static\]

Removes marker at *idx*.

If no marker is defined for given *idx*, or **SoMarkerSet::markerIndex** is NONE (not removable), FALSE is returned. If everything is OK, TRUE is returned.

### SbBool SoMarkerSet::isMarkerBitSet (int idx, int bitNumber) \[static\]

Not supported in Coin. Should probably not have been part of the public Open Inventor API.

## Member Data Documentation

### SoMFInt32 SoMarkerSet::markerIndex

Contains the set of index markers to display, defaults to 0 (CROSS\_5\_5). The special value NONE renders nothing for that marker.
