✨ NAME ✨

okay so bestie, welcome to the Coin manual 💖 — you're in section 3, which means we're talking library functions and classes, and today's main character is SoShaderParameter2i.

SoShaderParameter2i is the class you use to define a two-dimensional integer value as a shader parameter. that's it, that's the whole vibe 🌸 — a 2D int, but make it a shader parameter, and make it a whole class about it. iconic honestly 👑

so like, if you've got a shader that's hungry for a lil pair of integers, this is the class that feeds it 🍓 no cap, it's giving exactly what it says on the tin ✨

✨ SYNOPSIS ✨

#include <Inventor/nodes/SoShaderParameter.h>

okay so that's every single inherited member, listed, nothing skipped, we ate that fr fr 💅 and like… the actual detailed description of what this node even is?? coming right up, bestie, don't go anywhere 🫶

✨ Member Function Documentation ✨

Okay bestie, now we're getting into the methods — the actual functions you can call. It's giving "let me introduce you to the squad". 💅

SoType SoShaderParameter2i::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. Lowkey the class ID plug. ✨

SoType SoShaderParameter2i::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. No cap, it's the vibe check for your objects. 🦋

Reimplemented from SoUniformShaderParameter.

const SoFieldData ** SoShaderParameter2i::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. Basically: "not me, don't worry about it." 🙈

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

const SoFieldData * SoShaderParameter2i::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. Periodt. 💀

Reimplemented from SoUniformShaderParameter.

void SoShaderParameter2i::updateParameter (SoGLShaderObject * shaderObject) [virtual]

Updates the shader parameter in the OpenGL state with the content of the value field. It's literally syncing your vibes to the GPU. 🔥

Implements SoUniformShaderParameter.

🎀 Member Data Documentation 🎀

SoSFVec2i32 SoShaderParameter2i::value

The shader parameter value. That's the whole tea. 🍓
