first things first, you gotta pull it in:

💖 Detailed Description 💖

so the SoVRMLCone class is literally the Cone object representation. that's it, that's the job 🍦

heads up bestie: the detailed class documentation here 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. no cap.
Cone {
  field     SFFloat   bottomRadius 1        # (0, inf)
  field     SFFloat   height       2        # (0, inf)
  field     SFBool    side         TRUE
  field     SFBool    bottom       TRUE
}

The Cone node specifies a cone which is centred in the local coordinate system and whose central axis is aligned with the local Y-axis. The bottomRadius field specifies the radius of the cone's base, and the height field specifies the height of the cone from the centre of the base to the apex. By default, the cone has a radius of 1.0 at the bottom and a height of 2.0, with its apex at y = height/2 and its bottom at y = -height/2. Both bottomRadius and height shall be greater than zero. Figure 6.3 illustrates the Cone node. 👑

Figure 6.3

The side field specifies whether sides of the cone are created and the bottom field specifies whether the bottom cap of the cone is created. A value of TRUE specifies that this part of the cone exists, while a value of FALSE specifies that this part does not exist (not rendered or eligible for collision or sensor intersection tests). When a texture is applied to the sides of the cone, the texture wraps counterclockwise (from above) starting at the back of the cone. The texture has a vertical seam at the back in the X=0 plane, from the apex (0, height/2, 0) to the point (0, -height/2, - bottomRadius). For the bottom cap, a circle is cut out of the texture square centred at (0, -height/2, 0) with dimensions (2 × bottomRadius) by (2 × bottomRadius). The bottom cap texture appears right side up when the top of the cone is rotated towards the -Z-axis. SoVRMLTextureTransform affects the texture coordinates of the Cone.

⚠️ okay this part is important: the Cone geometry requires outside faces only. When viewed from the inside the results are undefined. so. don't go in there. it's giving void. 💀

🎀 Constructor & Destructor Documentation 🎀

SoVRMLCone::SoVRMLCone (void )

Constructor. makes the thing ✨

SoVRMLCone::~SoVRMLCone () [protected], [virtual]

Destructor. un-makes the thing 💅

🌸 Member Function Documentation 🌸

SoType SoVRMLCone::getTypeId (void ) const [virtual]

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

Usage example, copy it exactly bestie:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoVRMLGeometry.

const SoFieldData * SoVRMLCone::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 SoVRMLGeometry.

void SoVRMLCone::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

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

Reimplemented from SoShape.

void SoVRMLCone::rayPick (SoRayPickAction * action) [virtual]

Calculates picked point based on primitives generated by subclasses.

Reimplemented from SoShape.

void SoVRMLCone::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 calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

void SoVRMLCone::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.

void SoVRMLCone::computeBBox (SoAction * action, SbBox3f & box, SbVec3f & center) [protected], [virtual]

Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

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

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.
