#LWPro/Cylinder Mapping
9 messages in this thread
John:
I noted with interest in the current LWPRO the method used for putting
CMDR Ford's head into the hardsuit in a recent episode of seaQuest. What
I'd like to know is how was the image map constructed to cylindar map
around the humanoid head?

Hey, I'm not John, but I'd like to offer some ideas…and John, tell me if I'm
right or wrong!
1) If you notice, you only see the front half of the head, so a simple method
would be to light the face head on, and grab a video frame. Then, the face
could be mapped on to the front half of the head (Renammed,of course) and the
rear of the head is made a dark tone to blend into the shadows.
2)OR, with careful planning, you could grab 3 images, the left side of the
face, the front, and the right side of the face. Because the face is a
|
|cylinder, you would map each image onto its proper named side, using
cylindircal mapping.
To further mess things up, you could cut the head into sections, and add
rounded sides to each section. Then, after maping, blend in the edges by using
edge transparency. This would feather the sections of "skin" into one another.

It seems to me, if I remember the episode properly, that the actor's
"head" did, in fact turn from side to side in the hardsuit. Taking face
and profile shots of the actor would be easy, but making a 360 degree
image map would be the trick I'm after.

Pat,
When you take the front and profile maps of the person's head what about
putting a line of small dots on the person's face for reference marks. You
could use a fine tip felt pen and put a vertical line about at the corners
of the eyes. Then, when you've taken your front and profile imagemaps you
could use the dots to line them up properly. Once you have the image maps
joined into 1 image that you can cylinder wrap on the LW object you use
ToasterPaint to blend the dots into the skin color.
Not as good as the way Cyberware does it, but at least you don't need 150K
worth of hardware. ;^)

We just took a front on head shot and "peeled" it open from the back.
Bruce hall repainted the sides of the "mask" and got the ears and
everything to line up to a modified Humanoid head.

The head wrap: a case of plan, paint, render, re-paint, render, repaint,
re-render, etc! Yes, I do understand that mode of working! Kind-of like that
boolean cutting to fit a mapped image thing I had to do once before…just keep
doing it til it's right!

It was an image of Don Franklin looking straigh forward that our main
texturer, Bruce Hall, took and "unwrapped" from the rear and folded out
to make a kind of human mask.
JG
Are you saying that Bruce "created" the back & sides of the image map, say
by a paint program?

Yes, PhotoShop…
