electrocardiogram

[grandma]

I am trying to make an animated electrocardiogram with a darkish green background with the 'blip' animating a normal sinus rhythm. I want the blip to glow and leave a trail

that fades as the blip travels along the "path" just like you see in the movies. I have tried sprites constrained to a path placed in a tube shaped like a normal sinus

rhythm, but even with collision detection on I cannot keep them in the tube. I was thinking of applying a material that would travel along the length of the tube, but am at a

loss as to what or how. I remember John had something of this effect when he rendered a box as lines with something tracing the box lines and glowing. Could anyone give me any advice?

Hi Grandma:

 

Check out my animated flight console from Lost In Space at the bottom of the page here:

If the bottom of the scope is something along the lines you are looking for, let me know. I can post a small tutorial that would explain it. I belive that technique could be easily modified for what you would like to do.

 

Thanks...

Al

Thank you both. Al, I would like the tutorial if you get a chance.

I put together a quick small project that shows an ECG (see animation below).

 

Hope this is what you were looking for...

That's really nice. I'm going to work on it tonight. Thank you!
