okay so this is SoVRMLPointSet(3) from the Coin manual — section 3, the C++ library one. it's a long one bestie, so we're doing it in two parts. buckle up 💖

✨ NAME ✨

💖 Detailed Description 💖

So SoVRMLPointSet is literally just the class that represents a set of 3D points. That's it, that's the whole personality. Little sparkly dots in space, no cap 🫶

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

PointSet {
  exposedField  SFNode  color      NULL
  exposedField  SFNode  coord      NULL
}

Okay so here's the whole tea ☕ — the PointSet node specifies a set of 3D points, in the local coordinate system, with associated colours at each point.

The coord field specifies a SoVRMLCoordinate node (or instance of a Coordinate node).

🚨 Heads up bestie: the results are undefined if the coord field specifies any other type of node.

PointSet uses the coordinates in order. If the coord field is NULL, the point set is considered empty. PointSet nodes are not lit, not texture-mapped, nor do they participate in collision detection. The size of each point is implementation-dependent.

If the color field is not NULL, it shall specify a SoVRMLColor node that contains at least the number of points contained in the coord node.

🚨 Again, undefined behaviour territory: the results are undefined if the color field specifies any other type of node.

Colours shall be applied to each point in order.

💀 And one more undefined-behaviour warning, because apparently we're collecting them: the results are undefined if the number of values in the Color node is less than the number of values specified in the Coordinate node.

If the color field is NULL and there is a SoVRMLMaterial node defined for the SoVRMLAppearance node affecting this PointSet node, the emissiveColor of the Material node shall be used to draw the points.

More details on lighting equations can be found in 4.14, Lighting model (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.14).

⭐ Member Function Documentation ⭐

SoType SoVRMLPointSet::getClassTypeId (void ) [static]

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

SoType SoVRMLPointSet::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 SoVRMLVertexPoint.

const SoFieldData ** SoVRMLPointSet::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 * SoVRMLPointSet::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 SoVRMLVertexPoint.

void SoVRMLPointSet::initClass (void ) [static]

(No extra notes here — it's just out here existing, living its best life 🌈)

void SoVRMLPointSet::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 SoVRMLVertexPoint.

void SoVRMLPointSet::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

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

Reimplemented from SoVRMLVertexPoint.

void SoVRMLPointSet::generatePrimitives (SoAction * action) [protected], [virtual]

The method implements action behavior for shape nodes for SoCallbackAction. It is invoked from SoShape::callback(). (Subclasses should not override SoNode::callback().)

The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.

Implements SoShape.
