I just made a technology demo available of my Rapture Engine. The Rapture Engine is a fully 2D isometric engine very similar in performance and capabilities to the engine used in Age of Empires.
I began this project back in 2001, but got sidetracked and never got back to it. I pulled it out of mothballs yesterday and did some architectural changes and brought it up to date with GapiDraw. This is now a work in progress.
If you would like to see a couple screenshots and/or download the ARM/XScale version, you can do so at the PocketPC Studios website in the Developers/Downloads sections. If you have any comments/complaints/suggestions, fire off an email to me. =)
[April 15] Also rolled in my sprite engine and implemented a rudimentary sprite based GUI.
[April 15] Added full support for water and the associated fringe tiles (water->grass). I put up a few more screenshots and updated the demo download as well. A history is now included in the installation readme.
[April 12] Added support for water, as well as some minor architectural changes. I have a map editor written for DirectX that I will port over to the ppc sometime as well.
