After having verified the tools we will use, we started to analyze and design the SUSL project. Our approach on SUSL is a kind of three-tier-architecture. We use an input layer which is represented by the SketchUp framework. You are able to import various data types and SketchUp represents the mesh data in a 3D environment. Furthermore there is the processing layer. It is constructed modularly so that you are able to add new modules like a sculptie module. You need to create a new folder in the “/plugins/susl/” folder of SketchUp. After creating a “*.susl” file you only have to define your methods. The 2D and 3D Module are the ones we will implement in our thesis. The modules are able to write onto the third layer, the Second-Life-export-layer (output layer). A SL-container will be filled with SL Primitives by the modules. The export layer has to verify that no Second Life restrictions are violated (like 10*10*10 m restriction, 16kb script restriction and stuff like that) and it has to write a file which is copied and pasted into Second Life.

This is our current progress in the 2D Module. You are able to let SketchUp build up walls out of edges and export them into a text file in the SketchUp working directory. The script is “Copy & Pasted” into Second Life. Now you only need to touch the “Builder” and it will build the ground plan to walls. It is a prototype to test the technologies we like to use. Here are the pictures:
