I want to add smoke trails to my game''s missles like these people did in this image. So far i''ve got a nice array of vectors which gets filled up with the missles position as it flies along every .1 seconds, but i need some suggestions as to go ahead rendering this smoke trail now. my thoughts so far is to dynamically fill a vertex and index buffer as the missle goes along, but i''m wonder is there an even better way to do it or to use vertex/pixel shaders to do it. Suggestions? SkullOne - Hero Interactive http://www.hero-interactive.com

It looks like they are rendering the trail twice, with the second scaled up a bit, and more translucent.

Well i just dynamically create the smoke trail polygons as the missles fly along. Tie that together with a resource manager so you don''t constanly have to be allocating new vertex and index buffers and you''re ready to go.

Just a quick question for you zoomcrypt:

You are using quads that are alinged to the camera (billboarding), right? How did you manage to stitch together the multiple billboards to make the joints between billboards seemless?
