Description
You need to modify the files so to obtain the following effects:
1. Replace the cube with a more complex and irregular geometry of 20 to 30 (maximum) vertices. Each vertex
should have associated a normal (3 or 4 coordinates) and a texture coordinate (2 coordinates). Explain in the
document how you chose the normal and texture coordinates.
2. Compute the barycenter of your geometry and include the rotation of the object around the barycenter and
along all three axes. Control with buttons/menus the axis and rotation, the direction and the start/stop.
3. Add the viewer position (your choice), a perspective projection (your choice of parameters) and compute the
ModelView and Projection matrices in the Javascript application. The viewer position and viewing volume
should be controllable with buttons, sliders or menus. Please choose the initial parameters so that the object
is clearly visible and the object is completely contained in the viewing volume. By changing the parameters
you should be able to obtain situations where the object is partly or completely outside of the view volume.
4. Add a cylindrical neon light, model it with 3 light sources inside of it and emissive properties of the cylinder.
The cylinder is approximated by triangles. Assign to each light source all the necessary parameters (your
choice). The neon light should also be inside the viewing volume with the initial parameters. Add a button
that turns the light on and off.
5. Assign to the object a material with the relevant properties (your choice).
6. Implement both per-vertex and per-fragment shading models. Use a button to switch between them.
7. Create a procedural normal map that gives the appearance of a very rough surface. Attach the bump texture
to the geometry you defined in point 1. Add a button that activates/deactivates the texture.
Describe your solution in a short PDF document (2-3 pages) describing the techniques used, the advantages and
disadvantages of the proposed solution and the features of your solution.
How to submit the homework
