🦋 NAME 🦋

okay so welcome to the GLGETVERTEXATTRIBPOI(3G) manual page, bestie 💖. The main character here is glGetVertexAttribPointerv, and its whole thing is: return the address of the specified generic vertex attribute pointer. That's the assignment, and it ate.

💻 C SPECIFICATION 💻

void glGetVertexAttribPointerv(GLuint index, GLenum pname,
                               GLvoid **pointer);

🎀 PARAMETERS 🎀

  • index — specifies the generic vertex attribute parameter to be returned.
  • pname — specifies the symbolic name of the generic vertex attribute parameter to be returned. Must be GL_VERTEX_ATTRIB_ARRAY_POINTER.
  • pointer — returns the pointer value.

💅 DESCRIPTION 💅

glGetVertexAttribPointerv returns pointer information. index is the generic vertex attribute to be queried, pname is a symbolic constant indicating the pointer to be returned, and params is a pointer to a location in which to place the returned data.

The pointer returned is a byte offset into the data store of the buffer object that was bound to the GL_ARRAY_BUFFER target (see glBindBuffer()) when the desired pointer was previously specified. yes, that's the lore 🫶.

🔥 NOTES 🔥

The state returned is retrieved from the currently bound vertex array object. very "you are where you are" of it.

The initial value for each pointer is 0.

😭 ERRORS 😭

  • GL_INVALID_OPERATION is generated if no vertex array object is currently bound.
  • GL_INVALID_VALUE is generated if index is greater than or equal to GL_MAX_VERTEX_ATTRIBS.
  • GL_INVALID_ENUM is generated if pname is not an accepted value.
bestie, these are the vibe checks that will absolutely end you if you ignore them 💀.

👑 ASSOCIATED GETS 👑

glGet() with argument GL_MAX_VERTEX_ATTRIBS.
