SoShape(3)

📦 version 2.5.0, in fedora 43, fedora 44

okay so bestie, sit down, hydrate, because we're about to talk about SoShape(3) 💖 — the library function manual page for the class that is, and I quote, the superclass for geometry shapes. She's the mom of the whole shape family. The blueprint. The main character that never actually shows up to the party herself (she's abstract, more on that later, and yes it is giving mysterious 💅).

🌸 NAME 🌸

SoShape — The SoShape class is the superclass for geometry shapes.

Like. That's it. That's the whole job description. She's the parent class, the vibe-setter, the one all the actual shapes inherit their whole personality from.

✨ SYNOPSIS ✨

#include <Inventor/nodes/SoShape.h>

Inherits SoNode. 🫶

Inherited by SoAsciiText, SoCone, SoCube, SoCylinder, SoImage, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoNurbsCurve, SoNurbsSurface, SoSphere, SoText2, SoText3, SoVRMLGeometry, and SoVertexShape.

Look at that roster. Literally every shape you've ever loved is on that list. It's giving family reunion and SoShape is the grandma everybody visits. 👑

🔺 Public Types 🔺

  • enum TriangleShape — { TRIANGLE_STRIP, TRIANGLE_FAN, TRIANGLES, POLYGON, QUADS, QUAD_STRIP, POINTS, LINES, LINE_STRIP }

This is the menu of ways you're allowed to glue your vertices together. Every shape has to pick one when it starts drawing. No cap. 🌈

Public Types inherited from SoNode

  • enum NodeType — { INVENTOR = 0x0000, VRML1 = 0x0001, VRML2 = 0x0002, INVENTOR_1 = 0x0004, INVENTOR_2_0 = 0x0008, INVENTOR_2_1 = 0x0010, INVENTOR_2_5 = 0x0020, INVENTOR_2_6 = 0x0040, COIN_1_0 = 0x0080, COIN_2_0 = 0x0100, EXTENSION = 0x0200, COIN_2_2 = 0x0400, COIN_2_3 = 0x0800, COIN_2_4 = 0x1000, INVENTOR_5_0 = 0x2000, COIN_2_5 = 0x4000 }

A whole bitmask family tree of every file format / dialect a node might belong to. These are the values, character for character, don't go editing them: 0x0000, 0x0001, 0x0002, 0x0004, 0x0008, 0x0010, 0x0020, 0x0040, 0x0080, 0x0100, 0x0200, 0x0400, 0x0800, 0x1000, 0x2000, 0x4000. 💅

👑 Detailed Description 👑

Okay so the SoShape class is literally the superclass for geometry shapes. 👑

The node types which have actual geometry to render inherits this class. For convenience, the SoShape class contains various common code used by the subclasses. It's giving main character energy, holding all the shared code so the subclasses can shine. 💖

enum SoShape::TriangleShape

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. So like, not for you unless you're deep in the code. 🙈

🎀 Constructor & Destructor Documentation 🎀

SoShape::SoShape (void ) [protected]

Constructor. Just doing constructor things. ✨

Destructor. It's the end, bestie. 💀

💅 Member Function Documentation 💅

SoType SoShape::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:

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

SbBool SoShape::affectsState (void ) const [virtual]

Returns TRUE if the node could have any effect on the state during traversal.

If it returns FALSE, no data in the traversal-state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.

The default method returns TRUE, on a "better safe than sorry" philosophy.

virtual void SoShape::computeBBox (SoAction * action, SbBox3f & box, SbVec3f & center) [pure 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.

void SoShape::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.

🦋 const SoBoundingBoxCache * SoShape::getBoundingBoxCache (void ) const

Returns the bounding box cache for this shape, bestie. Heads up though: it might return NULL if no bounding box cache has been created yet. And if it's not NULL, the caller must check that the cache is valid before using it — you can do that with SoCache::isValid().

This is not necessary with Coin. Of course, if you choose to override it, it will work in the same way as Open Inventor. 💖

void SoShape::beginShape [protected]

void SoShape::beginShape (SoAction *const action, const TriangleShape
    shapetype, SoDetail *const detail = NULL)

Okay bestie, this is where the main character energy kicks in ✨. This method is used to generate primitives for a shape. It's typically called from a node's generatePrimitives() method. And if you have your own shape and want to write a generatePrimitives() method for that shape, it's probably a good idea to take a peek in the generatePrimitives() method for a similar shape in Coin. 👑

generatePrimitives() can contain several beginShape()/endShape() sequences. shapeVertex() is used for each vertex between beginShape() and endShape(). For instance, to generate primitives for a triangle you'd do something like this:

SoPrimitiveVertex vertex;

this->beginShape(action, SoShape::POLYGON);
vertex.setPoint(SbVec3f(0.0f, 0.0f, 0.0f));
this->shapeVertex(&vertex);
vertex.setPoint(SbVec3f(1.0f, 0.0f, 0.0f));
this->shapeVertex(&vertex);
vertex.setPoint(SbVec3f(1.0f, 1.0f, 0.0f));
this->shapeVertex(&vertex);
this->endShape();

Note that the SoPrimitiveVertex instance can simply be placed on the stack and not allocated. SoShape will copy the needed information when you call shapeVertex(). 🫶

Before calling shapeVertex(), you can set extra information for the SoPrimitiveVertex, including normal, material index, and texture coordinates. 🌸

This method is slightly different from its counterpart from the original Open Inventor library, as this method has an SoDetail as the last argument, and not an SoFaceDetail. This is because we accept more TriangleShape types, and the detail might be a SoFaceDetail or a SoLineDetail. There is no use sending in a SoPointDetail, as nothing will be done with it. 💀
