Assessment 3 and 4 overarching outline
1. Introduction
The assignment will involve using modern OpenGL to render a scene. Scene graphs are required in the modelling process and animation controls are required for hierarchical models.
2. The task
Figure 1 shows a room scene containing three objects, a robot and a window looking out onto a view. The whole scene can be modelled using transformed planes, cubes and spheres. The scene shows five poses of a robot that has entered a museum exhibition room. Pose 1 is on entering the room. Pose 2 is viewing a large mobile phone displayed on a plinth. Pose 3 is viewing a spotlight on the floor as it swings side to side on a stand. Pose 4 is viewing a large egg on a stand. Pose 5 is looking out of the window.
3. Requirements
You must satisfy all the following requirements.
3.1 The room
• Only two walls and a floor for the room should be modelled.
• The walls and floor should be texture mapped to look like a room in a museum. For example, the floor could be made of wood. The walls should have a paint pattern on them.
3.2 The window
• An outside scene can be seen through the window,for example, this might be a garden scene or a city scene. You could use a picture out of a window in your own accommodation or you could invent a picture.• Consider how you might do the scene outside:
o Should it be a texture map pasted onto the wall to look like a fake window and a scene (Figure 2a).
o Or should there be a hole in the wall and a texture map pasted onto another surface that is a certain distance outside the window? This will mean making the wall from a set of pieces, e.g. eight abutting pieces with the window as a middle area. Figure 2b illustrates this.
