Thread: Stuck on a few Statements/Questions on timing of Main Game Loop.

Could one of you please give me a bit of insight to each one of these 4 topics, I am just a little confused on what it is asking.

I have a good idea on what passive and active rendering are, and that the use of active rendering is more sutable for games programming.

I'm just not to sure about the rest.

-------------------------------------------------------------------------------

The timing of the main game loop is an important component of any computer game, since it impacts on the frame rate and the real-time physics calculations needed to make the game run at a realistic (or at least playable) rate. You are required to read up on the programming issues that affect this timing, and write a report that covers the range
of options available to a programmer. Your report should consider the following headings:


1. The distinction between active and passive rendering, and an explanation of the preferred mode for a game program.

2. The division of time between the physics (or game-model) update and graphics update stages, and an explanation and analysis of the relative importance of these in a game that involves real-time physics calculations.

3. Techniques for achieving accuracy in real-time physics, and an explanation of the trade-offs that may be necessary to do this.

4. Programming techniques that can be used to try to keep the frame-rate for graphics updates to some desired rate.

Thank you in advance!
Sean.

That is my main problem, I am finding it difficult to find places to read up on these topics.

I am not wanting you to do my homework, on the contray I am wanting to do this, however I have nothing to lead by and that is where I hope you guys will come in.

I have been able to find information on active and passive rendering and have read up on this to be able to make my own understanding of that topic, also topics such as Double Buffering, 80:20 rule for method optimizing.

Any information or links available to read will be greatly appreciated. I have books but unknown to me where this information is.

Thank you for responding.
