🌸 SoPickStyle β€” the NAME section, bestie 🌸

okay so first things first: this is part of the Library Functions Manual, and the star of the show is SoPickStyle(3) β€” the SoPickStyle class. It's a node for setting up how to do picking. that's it, that's the whole vibe, but stick around because there's a LOT of inherited lore below πŸ’…

πŸ’– Detailed Description πŸ’–

okay so, The SoPickStyle class is a node for setting up how to do picking. like that's literally its whole job and it does it flawlessly πŸ’…

By default, all geometry in a scene is available for picking. lowkey iconic behaviour but also sometimes NOT the move. Upon writing applications with interaction possibilities, this is often not what you want. So if you need to exclude parts of the scene graph from pick actions, use the SoPickStyle::UNPICKABLE and thank yourself later, bestie 🫢

You can also optimize pick operations by using the SoPickStyle::BOUNDING_BOX pickstyle. speed? we have it ✨

FILE FORMAT/DEFAULTS:

PickStyle {
    style SHAPE
}
ngl the default is SHAPE β€” that's the vibe it ships with unless you say otherwise 🌸

✨ Member Enumeration Documentation ✨

okay bestie, this is the enum lore and it's giving choices 🌈

πŸŽ€ enum SoPickStyle::Style

Enumeration of the available picking strategies.

🌸 Enumerator

  • SHAPE β€” Do "exact" picks, finding the correct intersection point(s), etc. precision queen πŸ’…
  • BOUNDING_BOX β€” Only compare pick intersection with the bounding boxes of shapes. This is usually much faster than SoPickStyle::SHAPE. speedrun mode ⚑
  • UNPICKABLE β€” The geometry following this node in the scene will not be available for picking. hands off, bestie πŸ™ˆ
  • SHAPE_ON_TOP β€” Do exact picks, like SHAPE, but sort the shape to the front of the list of picked points so it appears to be the frontmost item. This does not affect the SoPickedPoint pick coordinate though, just the sorting by depth done on the picked point list. main character energy πŸ‘‘

Since: Coin 3.0

  • BOUNDING_BOX_ON_TOP β€” Do picks against the enclosing bounding box of the object, like BOUNDING_BOX, but sort the shape to the front of the list of picked points so it appears to be the frontmost item. This does not affect the SoPickedPoint pick coordinate though, just the sorting by depth done on the picked point list. front of the line, no cap ✨

Since: Coin 3.0

  • SHAPE_FRONTFACES β€” Do exact picks, like SHAPE, but cull all the backface intersections from the list. Note that this logic is relative to the ray, not the view, in case the ray and the view direction are not aligned. frontfaces only, we don't do backface drama πŸ’–

The behaviour of this setting will also depend on the SoShapeStyle vertexOrdering and shapeType setting, which are used to flip frontfaces to become backfaces and vice versa and to turn backface culling on and off.

Since: Coin 3.0

SoPickStyle::SoPickStyle (void )

Constructor. welcome to the world, little node πŸ‘Ά

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

Destructor. bye bye, clean up your mess 🧹


πŸ’– Member Function Documentation πŸ’–

SoType SoPickStyle::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. iykyk πŸͺͺ

Usage example:

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.

Implements SoBase.

const SoFieldData * SoPickStyle::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. no fields? NULL it is πŸ«₯

Reimplemented from SoFieldContainer.

void SoPickStyle::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. just doing node things ✨

Reimplemented from SoNode.

void SoPickStyle::callback (SoCallbackAction * action) [virtual]

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. callback cutie πŸ“ž

Reimplemented from SoNode.

void SoPickStyle::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances. pick me, pick me πŸ’…

Reimplemented from SoNode.
