SoComplexity(3)

🎀 NAME 🎀

okay so bestie, this is SoComplexity(3), from the Library Functions Manual, and it's genuinely iconic. Here's the whole point of it:

SoComplexity — it's a node type, and its entire personality is setting the tradeoff between quality and performance. That's it. That's the job. 👑

🌟 Detailed Description 🌟

okay so real talk: the SoComplexity class is a node type, and it exists to set the tradeoff between quality and performance. that's the whole thesis statement 💅

By inserting SoComplexity nodes in the scene graph, you can control the accuracy by which complex shapes are rendered and the quality of the texture mapping used for geometry in the scene. two knobs, one node, obsessed.

Shape nodes like SoCone, SoSphere, SoCylinder and others, will render with fewer polygons and thereby improve performance, if the complexity value of the traversal state is set to a lower value. so like… turn the number down, get fewer polygons, go faster. no cap.

By using the SoComplexity::type field, you may also choose to render the scene graph (or parts of it) just as wireframe bounding boxes. This will improve rendering performance a lot, and can sometimes be used in particular situations where responsiveness is more important than appearance. (fr fr, sometimes you just need it to not lag, aesthetics can wait 🫶)

Texture mapping can be done in an expensive but attractive looking manner, or in a quick way which doesn't look as appealing by modifying the value of the SoComplexity::textureQuality field. By setting the SoComplexity::textureQuality field to a value of 0.0, you can also turn texturemapping completely off. yes bestie, completely off. 🙈

⚠️ FILE FORMAT/DEFAULTS: here's exactly what you get if you don't say anything, don't @ me:

Complexity {
    type OBJECT_SPACE
    value 0.5
    textureQuality 0.5
}

✨ Member Enumeration Documentation ✨

💖 enum SoComplexity::Type 💖

The available values for the SoComplexity::type field. pick your fighter:

Enumerator:

• OBJECT_SPACE — Use the SoComplexity::value in calculations based on the geometry's size in world-space 3D. 🌍
• SCREEN_SPACE — Use the SoComplexity::value in calculations based on the geometry's size when projected onto the rendering area. This is often a good way to make sure that objects are rendered with as low complexity as possible while still retaining their appearance for the user. honestly? kinda the smart-girl choice 💅
• BOUNDING_BOX — Render further geometry in the scene graph as bounding boxes only for superfast rendering. it's giving speed, not beauty 🔥

and that's only the beginning of this page — there's literally more coming, so don't go anywhere 🌈

🎀 Constructor & Destructor Documentation 🎀

SoComplexity::SoComplexity (void )

okay so this is the constructor, bestie. It's literally the new SoComplexity moment. Constructor. periodt 💅

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

and this is the destructor, protected and virtual, doing its cleanup era. Destructor. no cap 🫶

---

✨ Member Function Documentation ✨

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

okay so this 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 🔥

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. slay 💖

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

Implements SoBase.

const SoFieldData * SoComplexity::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. it's giving "no fields, no problem" energy ✨

Reimplemented from SoFieldContainer.

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

This function performs the typical operation of a node for any action. main character energy fr fr 👑

Reimplemented from SoNode.

void SoComplexity::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. lowkey iconic 🌸

Reimplemented from SoNode.

void SoComplexity::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. bestie, it's doing math and shifting the vibe check 📐

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

Reimplemented from SoNode.

void SoComplexity::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. literally throwing shapes at OpenGL, obsessed 💀🔥

Reimplemented from SoNode.

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

Action method for SoPickAction.

Does common processing for SoPickAction action instances. periodt 🎀

Reimplemented from SoNode.

void SoComplexity::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. counting triangles like it's a group-chat poll 🧚

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

💖 Member Data Documentation 💖

• SoSFEnum SoComplexity::type — Set rendering type. Default value is SoComplexity::OBJECT_SPACE.
• SoSFFloat SoComplexity::value — Complexity value, valid settings range from 0.0 (worst appearance, best performance) to 1.0 (optimal appearance, lowest rendering speed). Default value for the field is 0.5.

Note: without any SoComplexity nodes in the scene graph, geometry will render as if there was a SoComplexity node present with SoComplexity::value set to 1.0.

• SoSFFloat SoComplexity::textureQuality — Sets the quality value for texturemapping. Valid range is from 0.0 (texturemapping off, rendering will be much faster for most platforms) to 1.0 (best quality, rendering might be slow).

The same value for this field on different platforms can yield varying results, depending on the quality of the underlying rendering hardware. no cap, hardware tea ☕

Note: this field influences the behavior of the SoTexture2 node, not the shape nodes. There is an important consequence of this that the application programmer need to know about: you need to insert your SoComplexity node(s) before the SoTexture2 node(s) in the scenegraph for them to have any influence on the textured shapes.
