How could I put and arrange such pattern on the surface?
How could I produce “holes/breakthroughs” in the object geometry for 3D-printing (using the 3D-printed pattern as template to transfer the pattern to the “real” egg surface using a pencil)?
This would be very hard and time consuming. First you’d need to make an egg as an template for drawing onto it’s surface then retopologizing the painted surface with mesh. I’ve seen many custom egg shells on the site that would require very different approaches from one another. Another way would be by using boolean operations, but that’s a different story.
create a further uv-map (stripes or two circles) and “bake” the texture onto it
My idea to produce the “breakthroughs” for 3D printing is to export this uv-map (with baked pattern) as raster image, import in vector-processing-software (e.g. Inkscape) and create bezier curves/paths and export this vector format. Then import the vector format in blender and bend the curves/paths along the given egg-shape-path, that a new egg object is created. Then delete the “breakthroughs” or apply this new object to the given egg object using boolean.
Question to the blender experts: How to bend the imported curves/paths along a path and apply the boolean? I hope, that someone could give me an example.
you want to start from real egg pattern
and reproduce it in 3D blender
then 3D printer to make a new Egg !
if this is for a commercial applications then I would question the copyright issues !
leaving that to your attention.
some patterns are very simple and should be possible to use the retopo / spin tool in 3D
for other more complex patterns that might require a lot more work !
can you show one simple pattern then we an help you to get it in 3D!
upload image pattern texture
There’s a .blend file attached in the post. And, as mentioned in my first post I did it with boolean operations. To get the egg shape I only use a cube with a subsurf and cage modifier.
One thing that I haven’t mentioned OP is that with boolean operations he’ll need a powerfull PC since those carved egg shells contain a lot of detail.
Here is the pattern on the egg using the power of blender only . This pattern won’t work for 3d printing unless parts are connected.
True not good day for the OP haha.
@Ognjen
I meant the pattern that OP posted which I used, needs to be fixed in photoshop to connect all the black lines. @Ricky
No need for tutorial it’s easy, with this curvy patterns you just unwrap the sphere subdivide heavy bake the texture to vertex colors, select faces by color and delete. Next some laplacian smooth modifier for the borders and done. For geometric patterns I use an icosphere delete all but one triangle cut the pattern on that triangle and rebuild the icosphere again. I think I gave enough clues to go on and experiment since I believe it’s the best way to learn instead of copy paste what others do.
I never worked with a 3D printer. I will go to a regional FabLab, but I have to prepare the 3D model. Is there a simulation software for 3D printing? Maybe it’s better to use a cutting plotter to produce the template with the patterns?
As I already wrote, my only idea is to bake the texture onto an uv-map in blender, create the curves/paths in e.g. Inkscape (.svg), import .svg in blender and bend this mesh 2-times to get a new egg object. Then select the faces, that will be the “breakthroughs” (patterns) and simple delete them. But I’m only a beginner in 3D.
first pic with white egg does not have same shape then normal egg
looks more elongated vertically !
if you need to bake it
first how do you get the pattern in blender ?
you could take pic at different angle and trace it in blender and then project it onto the 3D egg model using knife tool
now if pattern is repeating you don’t need to repeat just make one segment then use the spin tool !
