Is glBegin deprecated?
Badly. The direct mode API with glBegin() and glEnd() is deprecated, largely for performance reasons. It doesn’t really support data parallelism, and relies heavily on the CPU—requiring at least one function call per vertex.
What is glBegin()?
The glBegin function accepts a single argument that specifies which of ten primitives the vertices compose. Taking n as an integer count starting at one, and N as the total number of vertices specified, the interpretations are as follows: You can use only a subset of OpenGL functions between glBegin and glend.
What is fixed function pipeline?
The term Fixed Function Pipeline commonly refers to the set of configurable processing state present in older versions of OpenGL that have since been replaced by Shaders of some sort.
Is OpenGL deprecated?

What is fixed function shader?
Fixed-function is a term canonically used to contrast 3D graphics APIs and earlier GPUs designed prior to the advent of shader-based 3D graphics APIs and GPU architectures.
What is glvertex3fv?
A pointer to an array of three elements. The elements are the x, y, and z coordinates of a vertex.
