Real-time snow accumulation

[deniz]

Hi all,

 

here is a video of my recent work on simulating real-time snow accumulation in LE.

That's pretty neat Deniz. Would look even nicer with a snow emitter! Nice work though.

[Paul Thomas]

Very nice, Deniz. Great work in progress.

[Josh]

That is a really clever idea.

[deniz]

thank you all guys, I am glad you liked it

this effect is still in its development stage.

after integrating it with the framework, I will post the updated video and maybe the binary as well.

 

Later I will add a snow emitter as well.

I did not want to do it for now, since I wanted to show just the effect itself.

[Josh]

Do you mind if I build this effect into the LE3 renderer? It could work for rain, too.

[David Will]

On the previous engine I was working with I commissioned someone to build in a similar effect, starting off like yours but then slowly fading in snow 'objects' that would automatically size and conform to the elevation and angles of the building/object to simulate thick snow. I scrapped the snow segment of the game a while back but I may bring it back, would be great to see something like this in LE3.

I agree. Having a weather system would be great!

A little OT there Josh, but you look entirely TOO happy.

That would be just great. As I wrote in my blog I would like to have in rain and wind in my GameEntry scene but have no idea how to do it.

you mean like this?

this is a related work of mine:

That video with the bunny model seems to be the way Crysis does their snow / water effects, almost like a projection light that applies onto vertices with a certain angle.

[Josh]

It's a lot more than that, he's got geometry adding to the surfaces, which is impressive.

[deniz]

yes, addtional geometry is added & modified to give that effect.

one of the questions was what function to use for varying the snow thickness with the angle.

[Josh]

Seems like a perfect opportunity to use geometry shaders.

[deniz]

Seems like a perfect opportunity to use geometry shaders.

 

that's why I asked before if there was support for geometry shaders in LE2

In fact, geometry shader might not be sufficient.

support for tessellation shaders would be better.

Awesome work Deniz! Thats very cool~

 

Always~
