Shadow volumes tutorial

Hello!

i just made a tutorial how to make shadow volumes. if you want to port the devil shadow system to opengl for example, this would be a way!

sorry...
if a link doesnt work. please check out the page
there are also a lot of more tutorials such as stencil rendering... www.devil-engines.net

It's really good to see you're writing a tutorial, although I have to confess - I didn't get it kind of. How do you determine if an edge is also a silhouette, or if it's just an enclosed edge within the mesh?

you dont have to know determinate wheter an edge is inside the mesh or at the border.

if you would only extrude edges on the border line of the mesh, you wouldnt have self shadowing...

however, you dont have to do this :)

you may also check out the two other tutorials on www.devil-engines.net

- shadow volumes
- stencil shadow rendering
- single surface particles

have fun and learn :)

In your single surface particle system, shouldn't the tforms rotate from the camera's coords to the world's coords, not from the world to world coords?

Yes, the code is definately wrong there. Probably not the case in the main particle engine though.
