Augmented and Virtual Reality (AL-703 (B)) - Important Questions

What do you understand by virtual reality? Explain the features of virtual reality.

Explain an algorithm which uses parametric equation for the purpose of line clipping. Using the same algorithm to find the coordinates of the line segment A(10,10), B(70,40), after it is clipped against a window.

Describe the purpose of Anchor, Collision, Group and Shape nodes in VRML with examples.

Discuss Collision detection using Generic VR system with help of the example.
