💖 SoShaderParameter2f — from the Coin manual, section 3 💖

okay bestie, welcome to SoShaderParameter2f(3) ✨ this is the page for the SoShaderParameter2f class, and she is serving one very specific purpose 💅

✨ NAME ✨

SoShaderParameter2f — the class you reach for when you wanna define a two-dimensional floating point value as a shader parameter 🎀

like. that's it. that's her whole thing. two floats, side by side, living their best life as a shader parameter 🦋 ngl it's giving "small but essential" and we love that for her 😌

no cap, this is only part 1 of the page — more is coming, so don't go anywhere 💖

✨ SYNOPSIS ✨

#include <Inventor/nodes/SoShaderParameter.h>

Inherits SoUniformShaderParameter. So yeah, everything that parent class brings to the table? She's got it too, no cap. 🫶

💖 Public Member Functions 💖

  • virtual SoType getTypeId (void) const — the classic "who even am I" type-identity method. 👑
  • virtual void updateParameter (SoGLShaderObject *shaderObject) — bestie this is the main character move: it updates the shader parameter in the OpenGL state using whatever's sitting in the value field. That's literally her whole job. ✨

🌟 Detailed Description 🌟

The SoShaderParameter2f class is used to define a two-dimensional floating point value as shader parameter. That's it, that's her whole vibe — two floats, one value field, zero drama. 💅✨

✨ Member Function Documentation ✨

okay bestie, this is the part where we meet the actual functions. grab a boba, we're going in 🧋

🦋 SoType SoShaderParameter2f::getClassTypeId (void) — [static]

static method, no instance needed, she does not need you to show up with an object. she just hands you the SoType object that's associated with objects of this class. that's it. that's the whole vibe. ✨

🔥 SoType SoShaderParameter2f::getTypeId (void) const — [virtual]

this one gives you back the type identification of an object that's derived from a class inheriting SoBase. what's it for, you ask? runtime type checking and "downward" casting. literally the whole personality is "who am I and can you cast me down". iconic behavior tbh 👑

reimplemented from SoUniformShaderParameter — so yeah, she's over here doing her own version of a thing her parent class already had. main character energy.

💜 const SoFieldData ** SoShaderParameter2f::getFieldDataPtr (void) — [static], [protected]

ngl bestie, this one is internal to the library. like, the manpage itself says it "is not likely to be of interest to the application programmer". so if you're just out here writing app code? this is not your moment. move along, gorgeous 💅

but for the record, since we keep every detail around here: it returns the SoFieldData class which holds information about fields in this node.

🎀 const SoFieldData * SoShaderParameter2f::getFieldData (void) const — [protected], [virtual]

this one returns a pointer to the class-wide field data storage object for this instance. and listen — if there are no fields present, it returns NULL. not empty, not vibes, NULL. so check before you dereference, okay?? 😭

reimplemented from SoUniformShaderParameter (yes, again, she's customizing)

🌸 void SoShaderParameter2f::updateParameter (SoGLShaderObject *shaderObject) — [virtual]

the moment we've all been waiting for 🫶 this one updates the shader parameter in the OpenGL state using the content of the value field. so like, whatever you put in value? that's what goes into the GL state. she's the bridge between your little field and the actual graphics pipeline. ate, honestly.

implements SoUniformShaderParameter

⭐ SoSFVec2f SoShaderParameter2f::value

the shader parameter value. that's literally the entire description, no notes, she's straightforward like that. it's an SoSFVec2f, so it's a vec2f, and it is the value. periodt 💖

and that's a wrap on SoShaderParameter2f(3) bestie!! this page is from Coin version 4.0.10, and the date on it is Thu Jun 25 2026 00:00:00. go forth and set your vec2f values, you've got this 💖🦋🌈
