help to understand making process

[Willy Tschager]

ok this is mine
but need some other things to do? because the eye are not the correct position on LDview

Noone said we are done. The 2D pattern of the eye has to be projected onto the 3D mesh.

This can be done with Philo's stand-alone prog SlizerPro:

https://philohome.com/isecalc/slicerpro.htm

which explains in detail how it works. Better used with Mike Heidemann's graphical front-end LETGUI:

or directly in LDPE.

   

* Open the pattern as well as your eyes sub in LDPE.
* Copy the triangles of the s03 mesh to the pattern file.
* "Front" view
* As the 3D mesh covers the right eye of the kitten and the pattern its left area, you are going to mirror the s03 mesh
* Select the mesh either in the Text Editor or in the 3D Editor
* "Action -> Scale selection". The Scaling dialog will pop-up.
* Put a"-" in front of the 1.0000 in the X field and make sure the manipulator is in the origin.

This is as you would manipulate the matrix by swapping on the axes.

   

* With the mesh at +X you will project the pattern at Z=0 to the mesh.

   

* Select the pattern
* "Back" view, cos' the mesh is in front of the pattern and you are telling LDPE the direction in which it should project
* "Tools... -> SlizerPro" Read the pop-up and understand what it does.
* "OK"

   

* You will get two patterns. The original with z=0 and the patterned mesh. You can casually delete the original pattern.
* You should always closely inspect the result. Infact there is an unnecessary vertex 2.626286 -30.727622 -15.455144 which should be merged but worse a projection gone wrong. Apparently I planed to merge that vertex to the triangle but didn't - my bad :-( Check your pattern in LDPC if the vertex in that area lays exactly on the mesh of the prim or if it is off. That's why I insist on accuracy when placing the vertices on the mesh or generating intersections. You can fix your pattern and repeat the projection process or try to fix the issue in LDPE.
* Substitute the 14 - Yellow with 16 - Main color; Round; Rectify; BFC ...
* Save your sub under 80686p01s03 and give it a proper description. I also recommend to save the original s03 mesh with the mirrored eye area. You will save a few bits because of all the "-" gone in front of the X values.

* Return to LDPC .
* Reposition the background for the nose.
* Place the vertices free-hand or use Splines or use prims, modifing them.

Keep in mind that we author ideal patterns where misprints, overlay, asymmetries have to be corrected.
