✨ SoScale(3) ✨

okay bestie, hydrate first 🍓 because we're about to read a whole Coin manpage together and it is long, but it's also lowkey iconic. welcome to SoScale(3) — part one of two, so don't wander off.

🌸 NAME 🌸

SoScale — the SoScale class is a node type for scaling scene graph geometry. that's it. that's the whole vibe. she scales things. 💅

🦋 SYNOPSIS 🦋

👑 Detailed Description 👑

The SoScale class is a node type for scaling scene graph geometry.

Use nodes of this type to apply scaling operations during scene graph traversals for e.g. rendering. Scale values are specified in a triple-value vector, with one scale factor for each of the 3 principal axes. so like, three numbers, three axes, three moods. 💅

FILE FORMAT/DEFAULTS:

Scale {
    scaleFactor 1 1 1
}
note the defaults bestie — 1 1 1 means "no change, no drama, identity behaviour." she's not doing anything until you tell her to. 🫶

🎀 Constructor & Destructor Documentation 🎀

⭐ SoScale::SoScale (void ) ⭐

Constructor. she's born. ✨

💀 SoScale::~SoScale () [protected], [virtual] 💀

Destructor. she's gone. 😭

✨ that's part 1, more incoming — don't go anywhere ✨

✨ Member Function Documentation ✨

💫 SoType SoScale::getClassTypeId (void ) [static]

okay so this static method hands you back the SoType object that's associated with objects of this class. that's it, that's the vibe 💅

💫 SoType SoScale::getTypeId (void ) const [virtual]

this one returns the type identification of an object derived from a class that inherits SoBase. bestie it's for runtime type checking and "downward" casting — iykyk 🦋

Reimplemented from SoTransformation.

💫 const SoFieldData ** SoScale::getFieldDataPtr (void ) [static], [protected]

so like… this API member is considered internal to the library, because it's not likely to be of interest to the application programmer. not the main character, lowkey 🙈

Returns the SoFieldData class which holds information about fields in this node.

💫 const SoFieldData * SoScale::getFieldData (void ) const [protected], [virtual]

returns a pointer to the class-wide field data storage object for this instance. and if there are no fields present? it returns NULL. no fields, no problem ✨

Reimplemented from SoTransformation.

💫 void SoScale::doAction (SoAction * action) [virtual]

this function performs the typical operation of a node for any action. generic queen behavior, she does it all 🎀

Reimplemented from SoNode.

💫 void SoScale::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. it's giving "let me tell you everything" 💖

Reimplemented from SoNode.

💫 void SoScale::GLRender (SoGLRenderAction * action) [virtual]

action method for the SoGLRenderAction.

this is called during rendering traversals. nodes influencing the rendering state in any way, or nodes that want to throw geometry primitives at OpenGL, override this method. throw those primitives bestie 🔥

Reimplemented from SoNode.

💫 void SoScale::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]

action method for the SoGetBoundingBoxAction.

calculates bounding box and center coordinates for the 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. center of attention? literally 🌸

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

Reimplemented from SoNode.

💫 void SoScale::getMatrix (SoGetMatrixAction * action) [virtual]

action method for SoGetMatrixAction.

updates action by accumulating with the transformation matrix of this node (if any). math girlies rise 👑

Reimplemented from SoNode.

💫 void SoScale::pick (SoPickAction * action) [virtual]

action method for SoPickAction.

does common processing for SoPickAction action instances. picking, choosing, slaying 💅

Reimplemented from SoNode.

💫 void SoScale::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. she counts, she adds, she delivers ⭐

nodes influencing how geometry nodes calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoNode.

🌈 Member Data Documentation 🌈

🦋 SoSFVec3f SoScale::scaleFactor

specifies scaling along the 3 axes.

to get a uniform scale applied to the affected shapes, set the scaleFactor field to a vector with the same value for all components. uniform = all three matching, no cap 💜

okay bestie listen up, this is the part where people mess up 😭 a common error when doing non-uniform scaling in a single direction is setting the value for the other two components of the scaleFactor vector to 0. this is obviously wrong — they should be set to 1 so you don't scale the shape(s) in the other two directions. do not do the 0 thing. i'm begging 🙈
⚠️ also be careful with setting scaleFactor component values to 0 or to negative values. most shapes should handle those cases somehow, but the results are undefined unless otherwise specified. undefined behavior is not the vibe, it's the 💀

the default value of this vector field is [1.0, 1.0, 1.0].
