💖 SoVRMLTextureTransform 💖

okay bestie, sit down, hydrate, and let me tell you about SoVRMLTextureTransform from the Coin library — it's a whole vibe, and yes it's a manual page, but we're gonna make it make sense. 🦋

✨ NAME ✨

SoVRMLTextureTransform — the class that defines a transformation applied to texture coordinates. it's giving "move my texture around, bestie" energy. 💅

✨ SYNOPSIS ✨

first things first, you gotta bring it in:

#include <Inheritor/VRMLnodes/SoVRMLTextureTransform.h>

wait no, i mean — literally, exactly, no autocorrect:

#include <Inventor/VRMLnodes/SoVRMLTextureTransform.h>

and plot twist 👑 — it Inherits SoNode. so everything SoNode can do, this baby can do too. nepotism but make it OOP.

📖 Detailed Description ✨

okay bestie, gather round 🫶 — the SoVRMLTextureTransform class defines a transformation applied to texture coordinates. that's the whole vibe. 💅

The detailed class documentation 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:

TextureTransform {
  exposedField SFVec2f center      0 0     # (-inf, inf)
  exposedField SFFloat rotation    0       # (-inf, inf)
  exposedField SFVec2f scale       1 1     # (-inf, inf)
  exposedField SFVec2f translation 0 0     # (-inf, inf)
}

The TextureTransform node defines a 2D transformation that gets applied to texture coordinates (go look at SoVRMLTextureCoordinate, iykyk 👀). This node affects the way textures coordinates are applied to the geometric surface. The transformation consists of, in this exact order:

  • a translation;
  • a rotation about the centre point;
  • a non-uniform scale about the centre point.

These parameters support changes to the size, orientation, and position of textures on shapes. but ⚠️ note: these operations appear reversed when viewed on the surface of geometry. fr fr, watch this:

  • a scale value of (2 2) will scale the texture coordinates and has the net effect of shrinking the texture size by a factor of 2 (texture coordinates are twice as large and thus cause the texture to repeat).
  • a translation of (0.5 0.0) translates the texture coordinates +.5 units along the S-axis and has the net effect of translating the texture -0.5 along the S-axis on the geometry's surface.
  • a rotation of pi/2 of the texture coordinates results in a -pi/2 rotation of the texture on the geometry.

so yeah, it's giving chaos but it's math chaos, it's fine 😌

The center field specifies a translation offset in texture coordinate space about which the rotation and scale fields are applied. The scale field specifies a scaling factor in S and T of the texture coordinates about the center point. scale values shall be in the range (-pi, pi). The rotation field specifies a rotation in radians of the texture coordinates about the center point after the scale has been applied. A positive rotation value makes the texture coordinates rotate counterclockwise about the centre, thereby rotating the appearance of the texture itself clockwise. The translation field specifies a translation of the texture coordinates. 💫

In matrix transformation notation, where Tc is the untransformed texture coordinate, Tc' is the transformed texture coordinate, C (center), T (translation), R (rotation), and S (scale) are the intermediate transformation matrices,

Tc' = -C × S × R × C × T × Tc

Note that this transformation order is the reverse of the Transform node transformation order since the texture coordinates, not the texture, are being transformed (i.e., the texture coordinate system). not me getting the order backwards and gaslighting myself 🙈

🏗️ Constructor & Destructor Documentation 🎀

SoVRMLTextureTransform::SoVRMLTextureTransform (void )

Constructor. it makes the thing. iconic behavior honestly. ✨

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

Destructor. it unmakes the thing. 💀

🔧 Member Function Documentation 🛠️

SoType SoVRMLTextureTransform::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. 💖

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

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

Implements SoBase.

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

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. 🫣

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

const SoFieldData * SoVRMLTextureTransform::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 SoFieldContainer.

void SoVRMLTextureTransform::initClass (void ) [static]

(this one's just vibes — the manpage gives it no description, so I'm not making one up 💅)

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

This function performs the typical operation of a node for any action. 🌀

Reimplemented from SoNode.

void SoVRMLTextureTransform::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.

Reimplemented from SoNode.

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

Action method for the SoGLRenderAction. 🔥

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

Reimplemented from SoNode.

void SoVRMLTextureTransform::getMatrix (SoGetMatrixAction * action) [virtual]

Action method for SoGetMatrixAction. 📐

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

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

Action method for SoPickAction. 🎯

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.
