Now, I said I wanted to get the editor written up before I posted the basic system, but I have had so many requests for it I thought I may as well get the base up and I can build on it as the system evolves. Before I get into the code, I'll explain a little of it's evolution. I first started...

Some of you that have come to this blog after going to the ReMix 08 conference are probably wondering, "Where is that source code Paul said would be here!?" Well, most of it is here, it's just smashed across a lot of posts. But, it's not all under one project ready for you to run and...

[youtube]http://www.youtube.com/watch?v=tnsSfwGfM3U[/youtube] So, we have seen PointSprite particles in 3D, but what about billboarding?? You may be asking at this point, what is billboarding and why would I want to use it when I already have a nice PoitSprite system that does the job I want...? A billboard...

[youtube]http://www.youtube.com/watch?v=0_qMAyr7RJY[/youtube] In this tutorial I am going to bind the emitter to a game agent, now you will have to forgive me as I have been very lazy, I have taken textures from the Creators Club particle example as well as some of the facing methods, have not bothered...

We have our classes so all I am going to do is now apply some pixel shader effects to both the particle system and the background image. I am going to describe how the pixel shader is applied to the particle emitter as the technique is the same for the background image. So, to our ParticleEmitter2D class...

Now we have a simple particle and emitter we can have a look at other blending modes, in the previous tutorial we did what is called and additive blend, this type of blending is called Frame Buffer Alpha Blending and a full description of this can be found in your DirectX SDK documentation. Additive...

[youtube]http://www.youtube.com/watch?v=AjsQiYaZ-po[/youtube] Was browsing the boards as I do and came across a thread on Ziggyware where a member was looking for a Particle Engine tutorial, at first I did not quite get what he wanted, so tried to clarify what he wanted with a post and suggested I could...

[youtube]http://www.youtube.com/watch?v=DNz_VdqHG_E[/youtube] Just posting a new clip of the cloud system I am playing with. As you can see using billboards gives a better effect when close to the clouds and/or passing through them. Need to sharpen up the shader now and get some nice lighting in there...

Well, I was asked by a member of our comunity (Jonathan Tan) to comment my skysphere cloud shader a little better, and he also mentioned to me a system written for Microsoft Flight Simulator 2004: A Century of Flight by Niniane Wang , so I took a look and was totaly blown away by it. So decided to try...

[youtube]http://www.youtube.com/watch?v=tG7BnVpc7TI[/youtube] Well I have gone movie maker mad eh!! Have added a fair few items into this release, as you will see in the video (keep calling them that, how old does that make me look!!) One of which is a 2D particle system, you can see this in action with...
