Weekly Report

Sad that we did not report for the last couple of weeks.

So right now we have made several progresses:

1. We made a rough user interface on Maya platform, using MEL. The user will have to draw some 2D enclosed shapes with Maya's curve tool to represent the two or three view images. Then these 2D shapes will be automatically duplicated and departed to form the "visual hull" in the Maya 3D window. Using the 3D tools, we can get the 3D cylinder with the input cross shape accurately. The boolean operators, including union, intersection and subtraction, are implemented by Maya 3D boolean tool directly. In this way we can get a result for most simple shapes and boolean computation.

2.However, what we want to make use of in Maya is only its 3 view plane and the 3D window. We want to compute the boolean operations ourselves in order to get a faster and more convenient approach. For this aspect, we are now trying to implement boolean operations for 2D polygons in one plane, which is the fundamental part of the whole algorithm. As Dr. Lane put it, we will also introduce OpenGL at this step to get a vividly graphic feedback for the algorithm.

Alright, that is where we are. We will make more progress and thank you for keeping an eye on us!
