Course Web for CS 559, Spring 2018

Due: Thursday, May 3rd (see the class late policy on the Syllabus) – NOTE: The last day the submission will remain open is one day before the final exam.

Synopsis: You will have the opportunity to complete and/or enhance your GraphicsTown project, and pursue extra credit by going beyond the requirements of assignments #7 through #9. In addition to optional embellishments described in the prior assignments, you will have the opportunity to incorporate (for bonus credit) elements of parametric curves and motion into your project.

Learning Objectives: The goal of this project is to give you the opportunity to venture deeper into advanced appearance effects (beyond what was minimally mandated before) and optionally gain experience with parametric curves and their use for crafting motion of animated scene elements.

Evaluation: We will grade on the scale explained in the Syllabus for turning a working version of the graphics town project that shows off the minimum required new features. We will give extra points for doing more than the minimum, or for creating particularly interesting things in the basic assignment.

Handin: Submit your code through Canvas [Link].

Description

In the fourth and final installment of the GraphicsTown project you will also the opportunity to wrap-up your project, adding any effects that fall under the scope of prior parts of the GraphicsTown project. In addition, you may experiment with adding motion to your GraphicsTown, and specifically implementing concepts related to parametric curves.

The requirements (for getting at least a “3” grade) are that you must submit a GraphicsTown project that satisfied the mandatory requirements of assignments #7 through #9. In more detail, this means that:

• If your programming assignment #9 already satisfies the mandatory requirements given in all of assignments #7, #8 and #9, you can submit exactly the same assignment and you will be granted a minimum of a “3” grade. This does not mean that if you got “3”s in all of #7 through #9, you can simply submit the same assignment, if that grade was leniently given to you without satisfying the mandated requirements.
• Any optional add-ons you have implemented before will count towards possible extra credit, but on a slightly more strict level of evaluation. No “5” will be given for programming assignment #10 without having implemented a significant extra body of work relative to #7 through #9.

For extra credit, consider doing some of the following:

• Implement even more advanced appearance effects, beyond the minimum required in #9.
• Use parametric curves to control the motion of objects in your environment. You can either have the motion be automatic, or optionally controlled by a slider (or both). You should aim to have both the position and the orientation of (at least some) objects be controlled by the parametric curve. You should also aim to have at least one object move around in a closed trajectory.
• Optionally include implementations of one or more different types of cubic curves (e.g. Hermite and B-Splines). You can either have a switch that selects between 2 different curve types, or you can have 2 objects following 2 different trajectories (each of a different type).
• Provide non-trivial user interaction to manipulate control points, i.e. altering the trajectory of objects based on user interface.
• Draw elaborate “tracks” that objects move on (for example, rail tracks on which a train moves on)
• Make vehicles with wheels that “roll” along a trajectory, in addition to moving along it.
• Or, design motion patterns and behaviors (hierarchically modeled objects, with elements controlled by curves?) that are particularly creative.

Due: Thursday, April 19

Synopsis: You will add textured objects to your GraphicsTown project in order to practice working with basic texturing.

Learning Objectives:
The goal of this project is to give you experience creating textured objects and to use the WebGL machinery for textures. The focus here is on image textures (and regular ones) – there will opportunities later for other forms a texturing.

Evaluation: We will grade on the scale explained in the Syllabus for turning a working version of the graphics town project that shows off the minimum required new features. We will give extra points for doing more than the minimum, or for creating particularly interesting things in the basic assignment.

Handin: You will turn in your assignment on Canvas [Link]

Description

By now you should be familiar with the Graphics Town Project, last week you had the first part – adding a few object to the framework. This week you will continue to add object – just that this time you’ll add texture to the them.

Technically, you can add texture to the objects that you made last week – but the idea is that you keep adding more and more stuff so that the project becomes more and more interesting.

For this week, your project must contain objects that do the following things:

1. You must have at least 2 different image-based textures on objects in your scene.
2. At least one of the images must be one you found on the internet.
3. At least one of the images must be one that you made yourself.
4. It is required that of the textured objects must apply a texture that “wraps” around many triangles. That is a bunch of triangles need texture coordinates – and the object that the texture is applied to cannot be flat. The texture must extend beyond the flat part of the object. Putting a picture on a face of a cube doesn’t qualify. Putting a picture that wraps around a cube does.
5. Your textures should be affected by lighting. (or at least some of them should).

It’s up to you what objects to make, and what textures to put on them – subject to the restrictions above. It’s OK to improve upon the objects you made for P7, or to add new object that make your town more interesting. We can look at the individual objects (that’s what the “Examine” mode is for).

These two new image-based textures are supposed to be image-based textures. You can of course add more than 2. And you can add procedural textures (in fact, the ground plane is a procedural texture). For this assignment, however, the main thing is to show that you can do image-based textures.
