I'm studying how scanline algorithms work and I'm wondering whether to determine the closest hit per each pixel a ray is shooted like ray tracing algorithms and, in that case, if bounding boxes are used to determine if there's an intersection or not

Answer 1

No, OpenGL is not a ray tracer. For depth testing you would typically use a depth buffer (check Wikipedia).
