A simple 2D gravity simulator between particles of varying sizes. The gravity strength, along with other parameters can be modified, with the program also performing 2D collision detection and reaction, using conservation of momentum and energy laws. This is a small program I knocked up for school, so is unfortunately not commented and has scope for improvement, but it could be of interest for basic graphics and physics programming.

PlotX allows the user to plot up to eight graphs (of the y = ax2 + bx + c type or NOW the x = ay2 + by + c type!) at a time. The user can also use many built in functions like Sin() and Tan() or Sqr() etc. in their expressions. Expressions are inputted using textboxes and evaluated with the Microsoft Script Control. Colour coding is used and multiple accuracy/speed settings are implemented for ease of use. The scale can also be changed and you can zoom in or out on the graphing area. Version 1.3.0 (THIS ONE) now supports both expressions beginning in 'y =' AND 'x ='! Another addition in version 1.3.0 are two new ULTRA high accuracy settings for very high accuracy graphing.

Thanks for downloading my code. This is really just an example of how to begin a world in Direct3D 8. The graphics aren't very good, but I hope that it maybe helps someone. It's pretty well commented and I think it's quite easy to understand. If you have any questions/queries, I'll endeavour to answer them. Please provide feedback and please vote. I wasn't going to post this yet, but I need some help to finish/make it better. I am stuck on how to do collision detection and also how to make colours in a texture transparent. If anyone can help with either of these problems, I'd be very grateful. You can either provide your response in the form of feedback, or drop me a line at r_hayden@breathemail.net. Hopefully, then I can release a complete D3D 8 world. Thanks for your time. Special thanks must go to Simon Price (http://www.vbgames.co.uk) for his excellent D3D tutorials and the help which he gave me on some of this project.

Version 2.0.0 of Richard Hayden's D3DWorld is a great improvement on version 1 (D3DScene) of my Direct3D 8-based 3D world. Lighting is now used in many shapes and forms to enhance this scene. I have also improved the program, making it more efficient and it runs slightly faster. I have added a church-style building to the world (complete with stained-glass windows), which looks pretty effective. Six times of day are now simulated realistically using lighting. The screenshot below was taken when the time of day was set to evening. Next I hope to add collision detection and transparency and billboarding, to simulate objects like trees etc. If anyone can help with the collision detection and transparency areas, then please do. (r_hayden@breathemail.net). I also hope to make a more realistic sky. So look out for any proceeding versions! Please vote and/or provide feedback in return for me making this code available to you! On my last submission I was quite dissapointed that out of about 400 visits, there were only 4 votes and about 2 feedbacks, apart from my own 2 comments. Really, the least people can do for developers who put up their code here for free, is to rate it!

This tutorial focuses on the use of the Dot Product of two vectors for back-face culling/removal in world space. Back-face removal is the process of checking every polygon before it is drawn to screen space to see whether it is facing the camera or not (ie. whether the camera can see it). If it isn't visible to the camera then there is no point in drawing it. Drawing it would just use unnecessary CPU power. This tutorial teaches you the basics of using this incredibly useful function in 3D game programming. It can significantly increase your frame rate!
