  • $\begingroup$ can you tell what is form of vanishing point in projection plane? It is normal $(x, y, z)$ in projection plane? $\endgroup$ Commented Oct 28, 2021 at 12:52
  • $\begingroup$ @User4567 im not sure it is a valid question. A vanishing point is caused by two coplanar lines. Any picture can have arbitrarily many vanishing points. Knowing what it is is meaningless for rendering. Projecting is a alternative way of constructing 3d from the way art books teach you to do stuff. $\endgroup$ Commented Oct 28, 2021 at 13:45
  • $\begingroup$ but the such image where vanishing point already exist in iamge, like railway track,, so what could be the form of that points? $\endgroup$ Commented Oct 28, 2021 at 13:56
  • $\begingroup$ @User4567 Does not matter its just a point like everything else. practical implementations work on practical data. The data you usually have tells how to connect consequtive points. Theres no way to know what form it takes it depends on the implementation details of my rendering engine and how i want to encode my data. $\endgroup$ Commented Oct 28, 2021 at 14:00
  • $\begingroup$ first of all your answer is very difficult to understand.. And I am struggling to understand vanishing point which is already existing in image and it's form. $\endgroup$ Commented Oct 28, 2021 at 14:02
