Snow?

[remus]

No yellow snow either

Hi Cadken, hi folks.

Maybe you can paint a surface with a photography of snow and then intersect it with a building.

To get the surface for the snow you could use some random numbers generated in Excel or any other spreadsheet you may use. Generate random Z coordinates for a grid of X and Y coordinates. Imports these as a cloud of points and triangulate the surface.

For the Z coordinate I would try something like 18 inches + a random number from 0 to 6. This will result in Z coordinates going from 18 to 24. Increase this range for a more hilly look. Decrease for a smoother one. Play with the initial number to adjust for the total snowfall.

Paint the resultant surface with a white color, maybe adding a touch a blue.

Just ideas.

I am not sure a ruby would work right, unless ut's coupled with some sort of randomizing algorithm as snow does not accumulate evenly, and on steeper surfaces it won't gather.

I had a quick go at using sub-smooth on a few horizontal surfaces of a stock wooden fence to give an illusion of snow, I think it works fine.

then rendered it with vue.

WOW! very nice, I'm new to the sub-smooth thingy so I may have to mess around with that... so far that is very impressive...

Hello

I made some snow renderings using Maxwell recently for a project I am working on in Sweden. Attached are a few "process images". I made them because the project is very far north and will often be covered with lots of snow, so I wanted to explore how the forms of the building change with Snow on them. There's a post on a (Swedish) blog about the project if anyone is curious.... http://hem.neue.feber.se/art/56379/polar-circle-house/

The steps I used were more or less the following:

1. Make the thing you want to be covered with snow, then, set it in a smooth mesh landscape. Assign the landscape a "snowy" color and/or material for external rendering if you want to...

2. Use Fredo6's "Joint Push Pull" to create a surface - first, take the outside surface of the thing being "snowed in", copy it in place, make a new group (so it doesn't "stick"), and expand it by the amount you want the thing to be snowed in, say 12" or whatever;

3. As suggested above, use the subdive selection script from Whaat to deform & soften the snow;
   (here, it is very useful to use "creased edges" to keep sharp corners where the snow is hitting objects..."

4. Render! (Note I forgot to put snow on the neighbor's house but still you get the idea...

5. If you have time (I didn't for these) go over with P-shop and correct any "leaks" ...

PS

here it is with no snow, just for reference....

i did this some time ago in podium using photosho to dirtmap and snow effects

Animated Water Reflection Freeware: Adding Realistic Water and Weather Effects with Sqirlz Water Reflections

Sqirlz Water Reflections is a versatile freeware program that enables users to add realistic water effects, such as rippling pools, raindrops, and snowfall, to both images and existing AVI video files.

Xiberpix (www.xiberpix.net)

You can make animated snow with this program. It's pretty cool.

You can't beat a bit of arial photography and some mapped textures. Here's a model from the old forum that I hope the author (Hermes?) doesn't mind me posting here.

Alan beat me to it, I was just going to say that those are some of the best snow scenes I have seen.

This is an interesting topic and if somebody make ruby it will be very nice!

[Tobobo]

If you wanted to mull some wine on you PC you could use the Component Spray tool to place white blobs over your model. but I suggest some fire suppressant precautions on stand by.

Joking aside it could work, will need some refining tho

I believe sub-divide and smooth and sandbox tools is good enough for a snow scene.

very nice! def inspiration!

Excellent work there Solo. Only one thing. You need some icicles hanging off the eaves. If you'd like you could come for a visit and see some first hand.

Icicles shouldn't be hanging from eaves at this time of the year. Signs of a badly insulated and ventilated roof, in our parts. In spring some can be tolerated courtesy of the

Anssi, you folks there in Scandinavia know how to build houses for winter conditions better than we do. I know there should be no icicles but there are. Or maybe it's because we're far enough south that we still get some sun this time of year.

[Gaieus]

We haven't even had snow this winter but the sun is shining at the moment. I haven't even turned on heating yet (the adapter of the lappy is nicely warming my feet under the desk)

So where are those icicles?
