GLVERTEXATTRIBDIVISO(3G)

✨ NAME ✨

okay bestie, this is GLVERTEXATTRIBDIVISO(3G) from the [FIXME: manual] manual — the page for glVertexAttribDivisor, aka the function that modifies the rate at which generic vertex attributes advance during instanced rendering. 💅

🧾 C SPECIFICATION 🧾

void glVertexAttribDivisor(GLuint index, GLuint divisor);

🎀 PARAMETERS 🎀

• index — specify the index of the generic vertex attribute.
• divisor — specify the number of instances that will pass between updates of the generic attribute at slot index.

💖 DESCRIPTION 💖

glVertexAttribDivisor modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives in a single draw call. If divisor is zero, the attribute at slot index advances once per vertex. If divisor is non-zero, the attribute advances once per divisor instances of the set(s) of vertices being rendered. An attribute is referred to as instanced if its GL_VERTEX_ATTRIB_ARRAY_DIVISOR value is non-zero. ✨

index must be less than the value of GL_MAX_VERTEX_ATTRIBS.

📝 NOTES 📝

glVertexAttribDivisor is available only if the GL version is 3.3 or higher.

💀 ERRORS 💀

GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBS.

bestie, this is the “respect the limit” warning: index can’t be >= GL_MAX_VERTEX_ATTRIBS. no cap. 🙈
