Can a shader be attached to more than one program object?
This is from the OpenGL 4.5 spec, section “7.3 Program Objects”, page 88 (emphasis added): Multiple shader objects of the same type may be attached to a single program object, and a single shader object may be attached to more than one program object. Compared with the OpenGL ES 3.2 spec, section “7.3 Program Objects”, page 72 (emphasis added):
How does the geometry shader work in OpenGL?
Between the vertex and the fragment shader there is an optional shader stage called the geometry shader. A geometry shader takes as input a set of vertices that form a single primitive e.g. a point or a triangle. The geometry shader can then transform these vertices as it sees fit before sending them to the next shader stage.
How do you use multiple shaders in GLSL?
The simple answer is you change them between each draw call. Set a shader, draw a teapot, set another shader, draw another teapot. For more complex stuff where you need to apply multiple shaders to just one object such as blur, glow and so on. You basically have everything rendered to texture(s).

How to generate multiple shaders in OpenGL stack overflow?
For example, the first fragment shader could contain this code: Then you need one shader with a main (), where you can chain the other shaders: Generate your shaders. That’s what pretty much all 3D engines and game engines do.
