Question

The first argument/parameter in the glVertexAttribPointer() function represents which of the following?

A. The number of vertices a shape will have
B. The index position of vertex or color data
C. The color of a vertex
D. All of the above

Answer 1

The first argument in the glVertexAttribPointer() function specifies the index position of vertex or color data in the shader program, not the number of vertices or the color of a vertex.

Step-by-step explanation:

The first argument/parameter in the glVertexAttribPointer() function represents the index position of vertex or color data in the shader program. This index corresponds to the location where vertex attribute data is passed to the GPU for rendering. It is important not to confuse this with the number of vertices in a shape or the color of a vertex, as these are not related to this particular parameter.
