💖 shaders — Shader Classes 💖

okay bestie, gather round, because this is the shaders(3) page from the Library Functions Manual and it is lowkey iconic. sit down, hydrate, let's go 🫶

✨ NAME ✨

shaders — Shader Classes. that's it. that's the whole name. short, sweet, main character energy 👑

---

🌸 SYNOPSIS 🌸

🎀 Classes 🎀

• class SoVertexAttribute — a generic node for handing over GL vertex attributes of literally whatever type you want. no gatekeeping here ✨
• class SoVertexAttributeBinding — the node that decides how those vertex attributes get mapped onto shapes. it's the matchmaker, fr fr 💅
• class SoShaderObject — no blurb included, she's mysterious and we respect that 🙈
• class SoShaderProgram — this one is used to specify a whole set of vertex/geometry/fragment objects all at once. the group chat admin of shaders 📋

🌈 Detailed Description 🌈

okay so. Coin-2.5 walked in and added support for Shaders, and it ate 💅

here's the tea: shaders replace the fixed function vertex and fragment processing in OpenGL by letting you, yes you, define the processing that happens at key points in the OpenGL pipeline. no more "the GPU decides, hope it goes well" energy — you're the director now, you're the main character 🎬

• Vertex shaders handle the operations that occur on each vertex 🦋
• Fragment shaders handle the operations that occur on each pixel 🌸

and the SoShaderProgram node in Coin is the convenient way to specify the code for your vertex and fragment shaders. one node, both shaders, obsessed 💖

then Coin-3.0 said "hold my strawberry drink" 🍓 and expanded the shader support by adding support for OpenGL Vertex Attributes.

the way that when you're using shaders, programmers are no longer limited to the set of attributes that OpenGL defines (glColor, glNormal, glTexCoord etc.)?? the freedom. the range. 🔥

so now you can define your own per-vertex data and pass them to the shaders using the SoVertexAttribute node. custom data, custom vibes, no cap 👑

ngl bestie, if you were still handcuffing yourself to glColor and friends while writing shaders, this is your sign to stop 💀
