easy rendering for Rhino in Windows

help with a rendering

I'm trying to place a rendering in a photo background and I'm looking for clever suggestions on how to do this. Here's a brief overview of the situation. I'm rendering a yacht and I would like to get realistic looking water reflections off a ground plane. I then want to remove the ground plane completely (put it on an alpha channel) and place the yacht in the photo. The rest I'm happy to do in photoshop. I've tried using the pic itself as my reflected background. This seems to work alright, except there are a lot of artifacts and elements in the picture that get mapped as well. Really I'm just looking for suggestions, perhaps something I haven't tried yet.

Not sure of the best way to do it in Rhino but you can acheive pretty convincing object reflections in Photoshop.

Basically you select the object you want to reflect,

copy it,

paste it (so it is on its own layer),

now select the new layer it is on and bring its transparency down a little

now go to the transform tools (under edit I think), now you can turn it upside down and distort it to look like the reflection

then bring down the transparency on that layer until your happy with its strength.

Hope that helps if you don't get answers you need to do it in Rhino.

I had a similar problem where I had put a "covered structure" in a playground scene and I could not get shadows to fall on the bitmap, ended up "faking" the shadows in PS.
