## 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.)

## Member Enumeration Documentation

## MarkerType

enum SoMarkerSet::MarkerType

Defines the different standard markers.

## Constructor & Destructor Documentation

## SoMarkerSet()

SoMarkerSet::SoMarkerSet | ( | void |  | ) |

Constructor.

## ~SoMarkerSet()

SoMarkerSet::~SoMarkerSet | ( |  | ) |

protected virtual

Destructor.

## Member Function Documentation

## getClassTypeId()

SoType SoMarkerSet::getClassTypeId | ( | void |  | ) |

static

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

## getTypeId()

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.

## getFieldDataPtr()

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.

## getFieldData()

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.

## initClass()

void SoMarkerSet::initClass | ( | void |  | ) |

static

## GLRender()

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.

## getPrimitiveCount()

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.

## getNumDefinedMarkers()

int SoMarkerSet::getNumDefinedMarkers | ( | void |  | ) |

static

Returns the number of defined markers.

## addMarker()

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);
SoMarkerSet::getNumDefinedMarkers
static int getNumDefinedMarkers(void)
Definition SoMarkerSet.cpp:1319
SoMarkerSet::addMarker
static void addMarker(int idx, const SbVec2s &size, const unsigned char *bytes, SbBool isLSBFirst=TRUE, SbBool isUpToDown=TRUE)
Definition SoMarkerSet.cpp:1427

This will provide you with an index given by MYAPP_ARROW_IDX which can be used in SoMarkerSet::markerIndex to display the new marker.

## getMarker()

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.

## removeMarker()

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.

## isMarkerBitSet()

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

## markerIndex

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.
