This project's report requires you to plan your approach before you begin writing code, so read the whole document before beginning implementation.

Write a procedure that generates a regular heightfield in data-files/model/heightfield.offwith elevation given by the grayscale values of an image file.

Implement the following by extending the Cubes project. For all shapes, there should be no colocated vertices. For the meshes, you may use arbitrary indexed convex-polygon faces that G3D will automatically tessellate into triangles on load.

This project's report requires you to plan your approach before you begin writing code, so read the whole document before beginning implementation.

Create data-files/model/cube.off, an axis-aligned cube with unit edge lengths, centered at the origin. You may make this file in a text editor directly, or write a procedure to generate it.
Create a procedure (function or method) named makeCylinderthat generates a file data-files/model/cylinder.off given a radius and height. This file should be an indexed convex-polygon mesh for a cylinder about the yy-axis that is centered at the origin.
Create a user interface for invoking makeCylinder. Use number boxes for the parameters and a button labelled “Generate” to actually launch the execution. Display a message on screen while generating and then flush the G3D::ArticulatedModelcache, and reload the current scene on completion.

1. The glass must have nonzero thickness for the bowl part that contains the liquid. It cannot have any “exposed backfaces”.
2. The glass must have a stem or thick base that is not penetrated by an inner well (i.e., you can't just double all surfaces).
3. The glass must be geometrically closedand water tight (i.e., it should topologically be a sphere)
