I'm trying to create joints on top of an animated Alembic mesh in order to use them later as a skin deformer.The current issue is that the joints are following the geometry.
Do I need to create a proper character rig for that? Is there a simple way to connect them directly to the original geometry without to have the package "duplicated geometry/blendshape/follicle"?
Many thanks,

I’ve been stuck for days, and couldn’t figure it out.
I’m trying to put a small graphic (as in Team Badge, and player’s number at the back) onto a basketball jersey. I can’t use Texture as anything I specified will cover the whole jersey.
From this https://threejs.org/examples/#webgl_decals I believe decal is the way to go. What I don’t understand is that I need to shove a Mesh into the Constructor of DecalGeometry. What kind of mesh should I use? Not the mesh of the basketball jersey?
Is this the right step?
get the upload of PNG from browser
create DecalGeometry using an arbitrary Geometry (may be a square?)
specify some material (I want it to be transparent)
create a new mesh using the above DecalGeometry and material (I can’t figure out what values to use for the decal projector…)
load the PNG into a Texture
load the basketball jersey’s Mesh
merge the basketball jersey’s Mesh with the new Mesh containing the DecalGeometry
Also, how do I control the size of the graphic inside the DecalGeometry? As the graphic has color, I’m not sure if the basketball jersey’s color will affect the graphic and make the graphic look broken?
Thanks a lot!
I am trying to create a particle system in SceneKit. I use the
particleSystem.birthLocation = .volume
option on a SceneKit node. This is working fine for built-in SceneKit shapes like SCNBox or SCNCylinder but now I need to make more complex meshes in Blender for use as the emitter. As simple test I tried exporting the default Box you get in Blender. However, when I try the exported .dae file I get the following error in the console.
[SceneKit] Error: Cannot use volume generation on a generic mesh. fallbacking on surface
Even the surface emitter it creates is not correct and consists of 3 triangles.
I've tried various options in the Blender export but I can't get this to work. Anyone have any ideas?
has anyone had luck efficiently converting an MLMultiArray to custom geometry? I've been able to convert MLMultiArray -> UIImage, though unsure how to efficiently create a custom geometry.
Big picture - I'm trying to mask a Scenekit Scene by utilizing an SCNNode with custom geometry. Essentially, I'd like to create a portal effect as seen in many of the online demos/tutorials. Though, rather than using an SCNBox as the geometry for the masking node, I'd like to use output data from my CoreML model as the "masking" shape.
If anyone can share code samples or high-level approaches, I'd greatly appreciate it! Thank you

I am using the Archilogic editor to create 3D models of building interiors.
How can I measure the distance between two objects?
Unfortunately there is currently no dedicated feature within the Archilogic editor that really solves this problem.
The only workaround that you can use to receive measurement information is to either select an existing wall or place a new wall into the scene and use it as a measurement tool. You can always see the length, width and height of the selected wall in the menu on the right side.

i need a help
i have a shape file that continue 3716 polygon record and want to draw this shape file where some of those polygons need to have a specified color
OR WANT a search technique to search this map for a point (lat-long) and get it's belong polygon but not by searching all polygons
i tries all, OpenJump-Source code, GeoTools,....
In GeoTools you can follow the Style tutorial to show you how to display your shapefile. There is no way to carry out a point in polygon search without at least examining the bounding box of each polygon but the GeoTools Query Lab will talk you through the basics of setting up a query (and if your shapefile has a spatial index then it will be quick enough).
