I had the idea the other day for creating shadow wrapped to terrain. I kind put it off until a came upon a topic requesting such a thing, and decided it was time to put my ideas into a program. I do not plan to develop this any further, but am sharing the result here for anyone to use. No credit is required, though I wouldn't mind a thank-you if it's used. Enjoy!

Edit: There was a slight problem where I forgot to set matching resolutions in the example. It still worked, but same resolutions looks way better. I also fixed it to make the "decal" stretch the sprite over the whole portion. Screenshot has been updated to reflect this change.

whoa, cool! it ran great here, but I'm not sure what the 500x500 is for, or the x and y res...could you explain what they do?
I messed with them a bit but I still don't get it.

anyway, nice job.

[hanson]

The 500x500 is the size of the model complete created. x and y res are the resolution of the model, the number of points on the x any y axis respectively. Higher res values == higher resolution model. I didn't make a perfect interpolation script to you may get a few bumps, but that's what the smooth_grid function is for. I didn't get a chance to fix the texture coords to only use one sprite when drawing the decal - If I have a chance I'll do that otherwise it's not too hard to fix yourself if you understand what's going on.

You did.
So its finally done. Its so smooth & works like a charm. Thank you Hanson.

I will learn form this and experiment on this. Thanks again for this

[hanson]

Thanks I just fixed a resolution issue I had in the example which caused intersection(decal was lower res than terrain), and made it so it stretches the sprite.

Very nice, but why the hell are the normals upside-down?

[hanson]

Thanks
Normals are messed up because I didn't take the time to do anything with 'em

Works for me. It's not a direct link, so make sure you go to the host-a page it sends you to
