Objectives:

• Procedural animation of a scene
• Modeling a dynamic scene with a Scene Graph and relative transforms, and enabling animation through the scene graph
• Generating texture mappings for objects of different shapes.
• Managing lights and camera
• Handling collisions
• Basics of a VR application

A set of objects are moving as one or more groups in a defined path. You join the scene as a VR avatar. You can choose any shape for your avatar. You should be able move around anywhere in the scene (simple turn left or right and move/stop controls)

• Each group has a leader, and the others follow such that each object follows only one other object in the group. E.g. the coaches of a train, a convoy of trucks, a line of ants, a flight of birds etc. The leader decides the actual path of motion, and the others adjust accordingly.

• The path has both static and dynamic obstacles. When the leader comes close to an obstacle, it changes its path to avoid and move past the obstacle without colliding with the obstacle(s). Think of a road with potholes/rocks and vehicles that suddenly appear in your path. Note that the avatar can also be an obstacle to the other scene objects and vice versa

• Your avatar can attach itself to one of the moving objects(E.g.sitting on one of the trucks). In addition, the avatar can also jump up and down or turn around while moving along with the object.

All the objects in the scene, including the ground, are rendered using textures. Use any reasonable texture images. Please use texture images that will show the correctness of the texture maps. Thus, use images such as photos of people/animals/natural scenes, world maps, etc, and avoid featureless textures like sand, wood, brick, fur etc. Use at least 3 distinct texture images across objects in the scene

• Based on user control, the textures of objects can be changed. That is, the image associated as the texture for an object can be changed on user input. You can use either the default texture coordinates for the object (if it exists) or a simple planar map

• User controls enable switching to cylindrical maps for some subset of objects

• User controls enable switching to spherical maps for some subset of objects

The scene is illuminated by multiple lights. The user should be able to switch any of these sets of lights off or on. Adjust the intensity of the lights so that all the effects are clearly perceptible.

• One set of lights is fixed to the ground, and each light illuminates a small region around it (e.g. streetlights).

• Another light is at a fixed location, but tracks one of the moving objects (e.g. a searchlight).

• Another light third is attached to one of the moving objects (e.g. a car headlight or a flashlight in a person's hand).

The scene is observed by 3 cameras:

• One camera is at a fixed position observing the whole scene. This is the default view.

• An overhead camera is mounted on a drone, with the camera facing forward and down. The user flies the drone, by adjusting its height (move up or down), turning it (left or right) and adjusting its speed.

• Another camera is attached to your avatar and simulates the avatar's view of the scene.
