Nice example of DX rain

I know it's DX, but I still found it quite nice.

That looks good. I wonder if you can do that with LW engine? I imagine you need animated rain textures for the 3D objects in your scene.

I'm not so sure. Gothic 4 claims to do it physically in this video:

They're using the surface normal to determine which way a texture scrolls. I really doubt their claim that puddles will form, that they make without showing any example.

 

There's nothing in the first video that is specific to DirectX 10 or even DirectX. It looks nice, but I am not sure what the point is since it is just an animated texture and some particles.

That first video is of a demo you can download from here: http://developer.download.nvidia.com/SDK/10.5/direct3d/samples.html#rain. I don't think it's right saying it's DX rain, the demo was made using DX but this can be done in OpenGL as well it just so happens to have been done with DX.

still... the overall effect is nice... thx for sharing the video...

 

always nice to see what others are doing...

What I got from that video that I thought was cool was that they removed the leafs from the tree when the camera got close. That would really help visibility of your character.

To limit rain to one area, I'd use an orthogonal camera rendered to a depth buffer to create a sort of shadow map. Then use this texture in the particle shader to determine where rain should appear. It's automatic, and dynamic. This is how STALKER does rain.
