#Creating Stripes ??
7 messages in this thread
I have created a rendering that is fairly complicated of a set
rendering for anindustrial show. The problem is that there has been
a change in the design and I have been asked about adding stripes to
the walls. I have tried to creat the correct shape in 2d shaper and
import the shape but I have had tremendous problems getting the shape
to aligne with the objects in the piece. I am wondering if ther is a
way to do this as decals? Any and all ideas would be helpful.
Tomarrow I start rerendering from scratch. I hate my job!!!
>>need stripes…
Do you mean stripes such as vertical stripes repeating in wall paper or paint?
Do you need to create geometry so you can get real close to the wall with the
camera or because the stripes need depth?
If you need repeating stripes, the easiest thing might be a simple texture map.
For example, to have repeating green and blue stripes just make a tall narrow
image with green on the left and and blue on the right. Fit your mapping icon
to the bitmap and stretch vertically as necessary. Then apply map and material
to each wall. You might have to split the wall units out into elements for the
best control. (Note that if the wall object is not aligned with an ortho view,
you may have to first align a user view as described below.) You can make a
matching bump map if the stripes need to have some depth. Am I over
simplifying things?
If you need a non-repeating pattern, you could create a single, much larger map
or create geometry.
To create geometry aligned properly with an existing object, turn on the 3D
display in the shaper and create shapes to fit. If your object is not aligned
with a standard orthgraphic view, use Display/UserView/Align first and select
that view before going to the shaper. You can use Create/Object/GetShape from
the *correct* viewport to bring in 2D shapes. If you loft shapes, it may be
easier to rotate the path before lofting so the object will be properly aligned
in the editor, or align the object as described below. (If I have a bunch of
objects to create an align, I'll usually rotate the path – if I have just a
few, I'll usually align them in the editor.)
If you are having trouble in general aligning a new object (I'll call it
NEWOBJECT) in 3D space with an existing object (I'll call it OBJECT), perhaps
because the existing object has been rotated or is at an odd angle, do this:
– use Display/UserView/Align to align a user view with the
desired faces of OBJECT
– use Modify/Object/Align WITHIN that user view to align
NEWOBJECT to the user view.
– within the user view, rotate and translate (move) NEWOBJECT
as necessary to manually align it with OBJECT.
Now the problem is aligning it along the other axis (into the user view). This
is easy if you use a temporary box object:
– create a box in any view
– align it with OBJECT as described above in the aligned user
view (I'll call this UserView1)
– create a new user-view, UserView2, perpendicular to UserView1
with Display/UserView/Align and picking one SIDE of the
temorary box
– translate NEWOBJECT in UserView2 as desired relative to OBJECT
– adjust NEWOBJECT in UserView1 if necessary
– delete the box
I hope this helps and isn't too confusing. If I misunderstood your problem,
please explain in more detail.

I use another method that doesn't require you to move between different User
Views and face alignments. Just do the following:
1) Create the other object slightly larger than the original object if
necessary.
2) Go to the Keyframer
3) Select Object/Tracks/Copy and select the original object.
Now depending on what you want in common between the original and the copied
object. If you just want to have the same rotation or scale and leave the
object in it's original position then
4) Select Scale and Rotation
4) Select Absolute(must do this since you want to change Key #1 for the object
which is shared with the geometry in the 3D Editor) then OK.
5) Then select the other copied object as the destination object.
The copied object will have the same alignement/position/etc of the original
object. If you want the object to have the same position then select position
as well.
This method can be applied to to align any object with another.

Good technique, if you need to align two objects relative to their
transformation matrices. If one object has been translated, rotated, or
scaled, the CopyTracks method will very nicely translate, rotate, or scale a
second object to match. (This is, of course, as long as the first object
hasn't had its xform matrix messed with by means of ResetXForm or by
Create/Object/Attach.)
However, it won't work (at least my tired brain can't see how) if you want to
align arbitrary faces of one object with arbitrary faces of another, as likely
in the striped wall problem.
To align two objects on the face level, as in sticking the base of one object
flat on to the surface of an angled part of another, I don't think you can
avoid either aligning a view with an object or aligning an object with a view.
(The tutorial "Aligning Objects and Views" on pg 8-23 covers this well,
answering the question "…how do you manipulate geometry that's at an odd
angle to the orghographic planes?".)

Yes, in order to align or orient an object at the face level then View Align or
Face Align remain the best techniques.

Assuming you've already applied a texture-mapped material to your walls, you
should be able to easily add stripes as a decaled Texture 2 map. Beyond that, I
really can't offer a suggestion without actually seeing your model — and I'm
afraid I wouldn't have the time to look at it anyway. If you provide more
detail maybe someone else can jump in with a suggestion.

PS — Think how much harder your job would be if you'd actually build the
set and had to repaint it with stripes.
Hi Eric,
<< aligning objects to another.. >>
If the object was moving…I'd like to suggest yet another alternative which
requires the use of the following script..
