Ice elevation rendering

Post by Maximus » 25 Jul 2012, 21:09

Hello, this is pretty much a shot in the dark...

i remember time ago i saw a compound (or was it a ICE compound+render tree combination) which will render out in gradient colors the elevation of the geometry.

for example like this Image

then i want to assign to each color a different shader. Anyone remember which compound it was? i'm tryin to find it but no success atm.

Thanks

by elevation you mean the point poistion in Y axis?

if so, here is a rough example... I didnt add the colors you talk about, as that is not key to solving the problem. cheers :)

Thanks for the help Gustavo, i used the Lagoa node which i just tried and worked, looked inside and it does exactly what you did :)

now off to understand how to assign different materials to those areas from the render tree!

thanks!

What about connecting the scalar output of the weighmap lookup into a mix2color node?

Can you not just do this directly in the render tree? No need for ice trees, apply an xy texture projection and give it a grad from top to bottom. use the grad to drive a mix2colours.

For mixing more than 2 materials you can use the gradient mixer (those little color thingys are texturable)

Learn something every day! I'm thinking loading some DTM/DGM into Softimage and trying this!
$ifndef "Softimage"
set "Softimage" "true"
$endif

Not sure if it still works, but there's the old Lume Landscape shader that did all this as well.
