Experiment Procedure

1. Understanding Point Representation:

   • Navigate to Instance -> Shape -> Vertices and locate the node corresponding to the point.
   • Edit the coordinates of the point to observe how it is displayed.

2. Modifying Coordinate System:

   • Navigate to Instance -> Coordinate System and adjust the origin and axis directions.
   • Observe how the point is redrawn using the modified coordinate system.
   • Take note of the absolute coordinates displayed.

3. Homogeneous Coordinates:

   • Points shown within '[' and ']' use homogeneous coordinates.
   • Modify the fourth component (w) and observe how it scales the point's coordinates.

4. Absolute vs. Relative Coordinates:

   • Edit the absolute coordinates of the point and observe how relative coordinates are calculated with respect to the coordinate system.

5. Switch to 3D:

   • Under the Display tab, switch to 3D view.
   • Perform all previous actions in 3D.
   • Use right mouse button drag to rotate the view and the mouse wheel to zoom in and out.

Note: This experiment focuses on understanding the representation of points in 2D and 3D space using both orthogonal and non-orthogonal coordinate systems in the context of computer graphics.
