ok, here's what i played with some....the first two images are the way it looks when it's turned off square from the camera....lol they suck... this was made with a terrain using a grayscale of a pic i found on web, and the material used was a parametric picture of the face again in color...

this is the close up of the best section....is closerr, but still not sure it looks 3D...rather then just a close up of the picture.... what do you think?

Actually... it looks a little warped, but I can see why. Where there are shadows on her nose in the image, there would be valleys in the terrain, so the light would hit it all wrong and draw new shadows and highlights. For something like this to work, the lighting on the image you use would have to be straight on.

I agree, this effect only works with monochromatic images whichhave direct lighting from the camera only.

ok, differnt lighting...sun off, and 4 lights, soft and positioned about....

Um... actually, I meant the original image shadows and not the ones made by Bryce, but that does look a little less warped.

Even with the original having light 'straight On, there will be incorrect depths, for example the cheel highlights often end up the same height as the nose highlight, when in fact they should be shallower. What you need is a z_buffered face image (see attached)

This effect does not work at all... I've been slaving for tens of hours over actually making a face from scratch in Rhino. Give up on this, I don't mean to dog on your abilities in heightmapping, but it really won't work. You can't height map a face... SO far you are jsut deforming it, something you could do with Photoshop by itself, and no Bryce necessary.. Here's an example of what REALLY modeling a face entails, and you can find much, much more in the Modeling forum. Note to Cool People : This head sucks, and was my first head attempt in Rhino... Thanks to 'Rosity for the Lofting tutorial!

Have to agree with you SDL, I've made some faces using SPline patches in MAx and it is literally a week of solid modelling to get something almost decent

LOL yea you guys should see this one from the side.....LOL I looked at it and was like EWWWWWWWWWWWWWWWWWWWW LOL

I wanna see the "EWWWWWWWWWWWWWWWWWWWW" render :) The easiest way to make this 3d-ish would be to model a head and then use a UV mapper to map the photo on it as texture. but still then it would only look good from the front, because the texture is made from only the front of the face. I can't help you much with the details of this, because I've never actually used a UV mapper, but if you want to model a head check out the recent tutorials in 3DWorld magazine. Those are really great, they helped me a lot. Also, your first head might not look very good as a head is super hard to model.

LMAOOOOOOO You asked for it!!! HAHAHAHAHAHAHAHH One from the left, and one from the right....LMAO in these, playing around experimenting, what I did was, made a terrain..took a pic, made it B&W and used it as the terrain....then took the color version and applied it as a mat....lol smoothed and softened the terrain alot or it lookes waaayyyy bad..LOL but was a col experiment none the less....

JC_01 posted Wed, 15 October 2003 at 3:32 PM

LMAO honestly??? I was just thrilled to get the picture to line up the the bumps on the terrain....LOL that was an experiment for me in playing with settings in the editors....lol the only one i did before this one was the tea cup i made right before my obp folders crashed...LOL (now if i could just get a decent model of a face or figure out a way around this problem, i could actually put some things in my pics besised houses and trees...LOL)
