   Snow rendering in real time
  I am looking for information about how to render snow in real time. Not snow as in particles just falling down, but snow falling and accumulating on the ground and so forth.If anyone have some nice information about this subject feel free to share them. So far I have almost only found non realtime information when searching the web. 
  Do you need it accurate or just visually pleasing ?If its the latter I''d personally use a dynamic texture or a render target texture and build the snow blobs up in that. The texture wouldn''t need to be too big either because the detail in snow is low frequency so stretching a tiny map over a massive area will still look ok Or do you want side on depth too? ;  I remember there being a massive thread about this a while back. Hopefully someone can post a link to it.  ;  textured snow or just dots?

Thank you.The goal is to make something that looks like snow. It doesn''t need to be accurate as long as it is visually pleasing. ;  an ideea:if u have a heightmap for the terrain why not a heightmap for the snow.render the snow like the terrain only use the terrain heightmap as base height for the snow. also u have to make sure that the snow heightmap is smooth: for a pack of snow the border is always at 0.   /*ilici*/ ;  The problem is I need a method that works with any kind of geometry. Not only heightmaps. There aren''t much done in this area that I can find (only one paper on snow acumulation in realtime). ;  u could calculate snow acummulation for every face in the level based on its the normal and the material but doing that will be very slow. so u should use heightmaps  /*ilici*/ ;  or a low resolution mesh and a bump map...that could produce nice results...and you don''t have update the bump map or the mesh very often...if something falls on the snow or someone walks on it, you''ll just have to change the bump map...
