In this assignment, we will construct a complete 3D model of CS 105 suitable for interactive visualization with a VRML 2.0 browser. The model should be complete (containing handrails, chairs, etc.), geometrically accurate (tolerance far less than 1 inch), and realistic-looking (with textures, etc.).
The goal of this assignment is to gain insight into traditional (interactive) 3D modeling methods. So, initially, please do NOT use procedural modeling methods (we will work on procedural methods for the rest of the semester). Instead, you should use an interactive 3D modeling tool. Cosmo Worlds (cosmoworlds), Autocad (acad), and possibly Alias (Alias), are available in Meca with on-line help. You can use any information available to you to guide your interactive modeling, including measurements made with rulers, positions from floorplans, and images taken by cameras for textures. Autocad files for the CS building floorplans are available here. The DXF file (ascii version) for the first floor is here.
We have partitioned the modeling task into several ``pieces'' to be
created by different groups of 2 or 3 people.
Pieces are assigned to groups on a first-come first-served basis. The union of all these pieces should be a beautiful 3D model of CS 105:
Each piece of the model should adhere to agreed upon guidelines so that
they all go together. We have agreed that the origin of the model is
along the edge of the floor and the front wall at the center of the
screen. The Y axis points up, and the Z axis points perpendicular to
the front wall out into the room. One unit is one meter.
Here are other general guidelines to aid the modeling process ...
We are working as an entire class on this project (the whole class gets the same grade). So, please help each other as much as possible. For instance, if you find a particularly effective way to perform a modeling task, please post a message to the news group so that others can benefit from your wisdom. Likewise, if you get a digital camera to take pictures for textures, let others know so that you can both take pictures at the same time.
After we are done, we will produce renderings of our model and compare
them to actual photographs taken from the ``same'' viewpoints in the
real CS 105. The class grade will be affected by the similarity of
these renderings and by the frame rate achieved during an interactive
fly-through of the model using a VRML browser, like CosmoPlayer.
