Due to popular demand for better presentation of the Cafu Engine to website visitors, gamers, programmers, developers, licensees and other interested parties, we're proud to present our April 2009 Cafu video:

"Cafu Engine Demo Clips"



Additional Information:

  • Why "Ca3DE"?
    Cafu was formerly named "Ca3D-Engine", or in short "Ca3DE", and was renamed to Cafu in December 2009 (learn more).

  • Better movie:
    Yes, Cafu can do better than this. We're working on a better movie already, e.g. with vegetation and without stuttering. Any help is very much welcome.

Playback Quality Options:

  • Better quality:
    Start the video in the player, then press the HQ button in the lower right corner:
    Image
    This provides a great image quality, but requires a faster internet connection. If you experience pauses, just watch the video again: It is fully buffered the second time, and then the playback is usually smooth.

  • Best quality:
    Download our source video: Ca3DE-DemoClips.wmv (ca. 40 MB, .wmv file format, 768 * 576 pixels)
    Tip: Use right-click, "Save Link As..." in order to save the video locally, then open with e.g. Windows Media Player, VLC, Totem Player (Linux), etc.

Please post your feed-back directly here in reply to this post, or at the videos YouTube page, where you can also place your comments and rating! :wohow:
... and while watching, remember to turn on the sound!! :wman:

Question about the outdoor scenes in the video, is the distant mountains (0:25-0:49) a backdrop or can you actually run towards them?

Hi VerbalTachi,
welcome to the Cafu forums! :welcome:

Partially: The farthest mountains are a backdrop, those in mid-range you can actually run to.
The terrain in this demo has a size of 1 km^2 at a resolution of 1m. Both can be easily be increased to increase the overall size as well. Best is if you just check out the live demo and see for yourself. :up:

What's the maximum map size that can be achieved? Is it possible to create a terrain size of lets say 50 km^2 or even bigger?

For a short answer, please consider this screenshot. It shows a 2D top/down view of the TechDemo map from the movie, loaded into the map editor CaWE:

The highlighted square indicates the dimensions of the demonstrated outdoor terrain (40320^2 map units, about 1 km^2), while the grid indicates the maximum map dimensions that CaWE can currently handle in a single map file (131072^2 map units, about 11 km^2).


The long answer is that there are several ways to achieve much larger terrains than the above image suggests:

A very simple but highly effective approach is to design multiple maps in a checkerboard pattern such that the outer terrain borders of each map seamlessly translate into the terrain of each neighbor map. For example, if you use a set of 3x3 maps, you can easily cover an area of 99 km^2. Automatically loading the next map when the payer comes near the border of the current map is easily achieved with a set of trigger brushes and a few lines of script code.

Also, there is no principal limitation to map and terrain size that can be kept in a single file either in CaWE or the Cafu engine itself, but using such large terrains requires the consideration of additional questions like terrain resolution, memory consumption, the details of creating and editing such terrains, etc.
It also requires some custom programming, if only for extending the maximum map dimensions that are available to the CaWE terrain editing tools and to customize all the detail issues that very large terrain bring with them.
