This game is looking freakin awesome!

Great videos. I love the soundtrack, as it’s very fitting for the ambiance, and your use of bright colors against the black background looks great too. I’m looking forward to seeing how this turns out.

Could you please explain how you managed to get such a nice jittering effect on the bolt.

[...] The pixel_size variable (a float2 with 1/target width in x and 1/target height in y) is used in DirectX 9 Shaders (Opengl and DirectX > 9 does not need this). The need for this “correction” is very well explained here. [...]

[...] XNA 4.0 works under DirectX9.0. In this environment, we have to make a “somehow strange correction” to the position of our vertices in the Vertex Shader (subtract the halfPixel size) when processing quads. The reason for this is the algorithm used in the rasterization unit (More info about this is Here). [...]

Hey Drilian, awesome article great work. Have been looking for something like this for ages!

I was wondering if you could please help me with something.

Im rendering each segment as three quads, two caps, and a middle. All the vert coordinates are generated into a single vertex buffer so the entire bolt can be drawn as a single batch. However, I have the problem you described above where the end caps of the segments overlap and blend together to create small circles along the bolt. Im using an additive blending when rendering the bolt.

I dont quite understand your solution to this. Could you explain a little more please? Also, what blending do you use when rendering your bolt?

Thanks!

Hey all!

Very good article I understand what is behind it but i have my problems to implement it.
Can someone help me to realize this in C#/XNA ? I don’t understand how to do the drawing with the animation (bolt1/bolt2 changes)?
Would appreciate a code snippet.

Greetz and Thx to all.
