I did a screen capture to show you how I would do it

What I usually do in such cases I draw immediately on the template.
  • I would import the relief into LDPC.
  • Start drawing the pattern optimized to the Reference Lines (so using Ctrl-T and Ctrl-P to move the vertices to the edges, respectively the  vertices of the template)
  • At the places where you used circles, I would draw them as well without taking the Reference Lines into account, but afterwards slice it manually with the CSG tool as the SlicerPro is sometimes giving issues when triangles are getting too small.
I started doing this since I made the Monster Fighter's Train Dish with Slicer Pro, gave me about a million Micro-triangles that I had to mend together. So I find it much easier to draw with the reference lines in place.
This is more or less the way I do 3D patterns.
  • import shape in LDPC
  • import background image
  • Create vertices (with vertices creation tool) nearby the point where a color boundary of the image crosses a template line.
  • Press ctrl+t immediately to move the vertex exactly on template line
  • when all these intersection vertices are created, I triangulate the pattern, adding additionnal vertices where needed with the triangulation tool. Remains tedious, but that's the most efficient way I found.
Otherwise... if you want to recreate create the patterned head without slicing (which makes sense here since the pattern is dense and head shape triangulation is random):
  • in LDPE, add the head shape to your flat pattern
  • Select the pattern and project it on the head: action -> merge to nearest surface(direction) and choose +x direction
  • Delete head shape reference (and correct the vertex that fell outside that reference)
  • Add condlines... (and change them to edge lines in the mane!)

This is how I usually do it as well. I also tried to do it for the horse but it gets so laborious (and messy) that I prefer adjusting my pattern in 3D. There is no benefit from trying to follow the mesh.

Philo,

this looks perfect! how did you do it?

Sorry, I thought the other methods for this pattern would be better (did you have a close look on my projection method here: https://forums.ldraw.org/thread-23710-po...l#pid34290 ?)

. So...
- Open the shape in LDPE, and with Edger2 tool create lines/condlines everywhere (set flat surface maximum angle to 0). Create unmatched edges too.
- Select everything (ctrl+A) and convert condlines to edge lines (C2L button).
- Select everything again, launch Ytruder. Projection on plane, value=0, condline threshold=0 (edge lines everywhere), operation axis X
- Select one surface, Select -> uncheck vertices/lines/condlines, then select -> all shown. Delete key to let only lines
- Slightly more tricky part: view head in front view, manually select all top edge lines with a marquee, hit delete key.

Done.

Edit: This process creates a lot of duplicated lines, may need to cleanup in text window.
The horse head is now at the PT:

In the end the way I had in mind didn't work out as plant - still too much work to do and the result wasn't satisfying.

* Moved the projection of the pattern at x=10
* Added Philo's edge file as subpart
* Used the outer rim of Philo's file to get the border at the right distance
* Brought in the existing 4492s00.dat - Animal Horse Head Side Surface
* Moved sections of the pattern (mostly based on color) very close to the surface
* "Merge To Nearest Face"
* CRTL+E of those vertices which were reused in the pattern from the imported template

Wow! That's an incredible pattern!
