3d Google Map Progress

Chris Bishop | 4 September, 2008 | 20:41
I am back from a week off. My wife and I really enjoyed our time away. No computers, just sitting by the pool and reading books. Aaahhh! The simple life. Now back to work. Cathy created two road models. They include curbs and grass, and one is a 15 degree turn. Road Model Images Road 1: Road Road 2: 15 Degree Road I was using a regular Cube Model and was able to duplicate a route in Google Maps in a scene. When I switched to Cathy’s Model’s everything was not displaying correctly. It turned out my Model was scaled at 1×1x1 and Cathy’s is not. I almost have Cathy’s models working. Google Maps in the Scene Using a cube Model and a texture. Changed to using the Road Model Looking closely at the images you can see in the image with the Cube Model the edges are all centered on each other while the Road Model are off slightly. Clean Code I decided to start organizing my code into proper classes from all the test classes I made so I can modify it more easily as I add features or need to make changes. Feedback I will post tomorrow about my technique for determining how to rotate a road segment. I rotate a road segment so the angle on Google Maps is matched in the scene. I currently have a huge if statement and I do not know if it is really required.

Portable Canvas v0.2!

Portable Canvas version 0.2 is available!!

It is now a usable browser, but restricted to pages on c3dl.org only. It can display canvas elements right out of the box, and doesn’t require anything else to be on your system (not even FF3!)*. It’s only been tested on Windows XP, but in theory it should be easy [...]

Namespaces and const

As our library expands with more functions, classes and global variables, the need for namespacing increases.  I started placing code in a C3DL namespace when I wrote the matrix stack operations.  However, yesterday I was looking in the constants.js file and saw the ‘tolerance’ variable.  It’s a const variable used when comparing floats to check [...]
