I have constructed a 3D model in Flash CS4/AS3 consisting of a space containing numerous block Display objects. &nbsp;For each block, I maintain an array of Vector3D vertices. &nbsp;I rotate a camera viewpoint around the constructed 3D model.<br />
<br />
My question: &nbsp;Given the current camera viewpoint, how do I determine the correct order for my block DisplayObjects? &nbsp;<br />
<br />
By calculating the average distance from the camera to a block's vertices, I can determine the correct order but only when all blocks are of the same dimensions and positions symmetrically about the space. &nbsp;However, this approach is too crude for the space that I need to represent.<br />
<br />
Thanks,<br />

How to determine Z-Order for 3D objects?

Adobe Flash (formerly Macromedia Flash) is a cross-platform multimedia and software platform used to embed animations, video, and interactive applications into web pages and desktop and mobile applications and games. Flash displays text, vector and raster graphics to provide animations, video games and applications. It allows streaming of audio and video, and can capture mouse, keyboard, microphone and camera input. The ActionScript programming language allows creation of interactive animations, video games, web applications, desktop applications and mobile applications.

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.
