I draw the school's svg files (the outside wall) pass to sam, and would like he use his svg viewer system to help me build up all the wall.

I read some information of the collision detection, it must be useful in our system, and found some simple code (a maze game) to reference........but sam asked me it is a parts of his 3D job, so, i stopped in this job.

Next a few day, I will do the Map viewer (just like the google map) to display our school floorplan.svg.
After our discussion, we need to trans formate the svg files to the kml
