Ideally I want to create a site where people could build their own cities and share them with others. I want to be able to send people to a URL, not tell them to install an app just to view a city I created. Running in a browser has so many advantages over an application which needs to be installed. It might be possible to create a decent sized city with limited vegetation that would run smoothly in a browser. but there’s not much point in working on that if the final product isn’t going to be very good.įortunately 3D models of buildings are mainly big rectangles. The mouse controls in the demo are awkward right now since this is a very simple scene. It’s not easy to learn but there are some nice preset procedural buildings that are very easy to edit. The island was created with a utility called Gaia, and the building is from Archimatix. Even a relatively small world with a simple building takes a minute to load and has a low frame was about the largest scene I could create without slowing everything to a crawl. I was hoping to write an interesting post about how to effectively optimize a natural scene, but the results are rather discouraging. The complexity of the rocks and plants requires large objects and many textures, and when you load them in a browser it tends to slow to a crawl. There are some very interesting WebGL demos ( ) but they don’t try to mimic the natural world. I’ve been experimenting with some WebGL scenes created in the Unity game design engine.
