The general procedures as to how to proceed with each project, when what to hand in and in what form, can be found in the project document.

Bitmapped characters

Design a representation and some instances for bitmapped characters and transfer them efficiently to construct text on the screen. Both monospaced and proportionally spaced. Needn't do entire alphabet.

Interactive curve drawing

Allow user to draw and adjust cubic Beziers in 2D.

Bezier approximations

System that generates Bezier approximations of circles, ellipses, ovals, fillets. Analyze accuracy.

Scan conversion for triangles

Develop more efficient scan conversion algorithms for triangles. Also fill with textures.

Phong shading

Do Phong shading for single light source and simple, static 3D sets of polygons.

Warn shading

Do Warn shading for single light source and simple, static 3D sets of polygons.

Thick, dashed lines

Extend line drawing to thick lines with specifiable dash patterns. Add curved arrowheads and dimension notes, as in technical drawings.

Freehand curved boundaries

Interactive drawing of closed curved boundaries, then filled with color from pallet. (Use built-ins for pallet.)

Line and polygon clipping

Develop your own clipping to your own "window" within a system-drawn window. Explore a few algorithms.

Bezier fonts

Design and draw some characters with curved boundaries and holes, and fill. Attempt italicization with procedures.

Hierarchical transforms

Implement 2D hierarchical structures so that when a containing shape is transformed, the contained shapes are too, e.g., rotations, translations, scaling.

3D objects

Display 3D objects as wire frames and filled. Can do hidden surface decisions manually.

Transforms library

Build and document a library or 2D or 3D transforms that anybody could use.

Isometric views and transforms

Do rigid transforms of 3D wire frames.

Perspective views

Construct perspective wire frames, static. Show different camera views from various angles, distances and magnifications.

Backface detection and fill

For simple convex objects, use backface detection and fill visible polygons with your own fill algorithms.

Hidden surface removal

System that can deal with occluding objects, not just convex. Use built-in filled poly calls.

Your own window system

Build a system to show at least two overlapping windows with line graphics, including window selection, shrink to icon, window dragging. (Do simple line clipping.)

"Master objects"

Build a system that allows a user to select and place copies of objects, e.g., pieces of furniture.

Engineering drawing

Display three views of the same object, using a single underlying representation.

Exploded views

Show exploded view of an object, including light lines connecting to original position, e.g., a table with four legs. Allow user to vary explosion amount from zero on up.

Menus

Using a window within a window, create menus that do something such as change colors, shapes or positions of objects.

Depth cueing

Using a fixed 3D scene, shade to reduce contrast with increasing depth.

Ray tracing

Simplest examples using reflecting spheres.

Multiple illumination sources

Uniform shading of built-in polygons.
