一出戲，周圍演示具有簡單的老校友的視覺效果（提供源代碼）。
A play-around demo for a simple, lightweight 3d-draw program. It does not much more than display objects made of flat colored faces. Things are arranged central to form a small surface so you can better zoom around that area. If the framerate is a bit sluggish and unstable - well it's all rendered in software, to keep things simpler and hardware-independent. The program was created with rad-tool 'Basic4android' (B4a) and the project source is available on request (mailto: kopperfeld@gmail.com). In the according source code, you may define own objects (by algorithms) and compose them to small worlds alike.
Controls:
Touch left side to accelerate in eye-direction
Touch screen to swerve around
Touch right side to switch renderstyle.
Known issues:
Possibly no sound on a Google Nexus 7.1 (older 2012 version) tablet, after an update to Android 4.3 (4.2 still works).
