Orient model as best fit to a planar image how?

[Steve1]

Hi,
V5, V8
In my quest to quickly map an emblem, code numbers, and camouflage mottle onto an aircraft surface, I also thought of this method. Is it possible and what steps to follow ?

1. place image using PictureFrame into build area.ortho view side
2. trace using curves tool the emblems details and panel lines and fittings, even rivets if visible…
3. use a command to orient points on the model to the same points in the image.
4. view remains ortho view pane (or whatever mode is decided on by Rhino) with the model now turned to be oriented as best fit to the image. That image still being planar and parallel to the viewport screen,
5. In other words as if on a perspex sheet and translucent with the model now fitting the image.
6. select the trace curves and details and use the project command to project to the surfaces of the model. I dont think project is possible in perspective view hence what I say in step 4 !

Now this might be of use for a code number or emblem., but mottled spray not so useful, still wish for a means of mapping a raster to a COMPOUND surface using source/destination points.

Can Rhino map a raster image using source and destination points?

Hi, V5, V8 I am trying to create side view profiles of aircraft. as such here is an example of a task, draw the badge accurately, as no one has done so. and having drawn accurately the cowling in Rhino, can I select lets say 10 points on the image and the 10 points on the model and say ‘go fit to those’ and have the image distorted and so on, and mapped onto the model ? I am also trying to plot mottles and codes and wing camo patterns onto such and having got the item as an accurate Rhino…

Then take the ortho side view of the model into Photoshop, use printscreen function or other means.

then draw the aircrafts profile artwork up !

Cheers

I’d personally use decals for this in Rhino.

But…have you taken a look at substance painter? You could paint your detail right on the model…

Hi
painting it onto the model would firstly involve mapping it to fit the model, (other post) so as to then draw over it, and if done thats job done anyway.

if i’m understanding you correctly, it sounds like you are looking for some sort of flow along surface type of thing. (take this thing and map it to that thing)

which for rendering would be more a of a uv mapping workflow.

do these videos from Brian James help?

and one on flow along surface-

let me know if I’m confused about what you are trying to do.

Hi,
best explained with image.
Having drawn the aircraft shape in 3d, I want to use it to recreate colour schemes, known as 'side view profiles.
for the generally flat areas, such as cockpit and fuselage side.
my thought was to place the image into scene, select points on it and indicate on model where those points were and then use orient, perhaps orient 3 point or orient 5point.
model then moves to realign to the image, that image remains planar to the PC screen.
though I really need the model to be ortho side view and the image mapped onto it.
as I need to get the model as a side view into photoshop, to trace over it, airbrush it to match the photo etc, not the oblique angled image, which started life there anyway !

such as these two examples to be ‘oriented’

unless the solution to my quest to map a photo to a 3D shape bears fruit.

Pshop distort tool 10mins fiddling getting nowhere.
