Can I somehow show the orientation of particles in a point cloud? I have a table of points, each storing a particle size (radius) and orientation vectors. I would like to see them rotate. My idea was to represent them as 3D sphere glyphs, and then apply a texture to them, but this does not seem to be available.

Use 3D glyphs representation

Are you trying to visualize a gaussian splatting data ?

Im using the 3D glyphs representation, sorry if I was unclear. 3D glyphs with Sphere as Glyph Type.

My data is not Gaussian splatting, just plain old spherical particles from a DEM simulation.

Great! Then that works for you ?

That part works, yes (always has). But how do I then apply the texture to each glyph? I’ve tried applying the TextureMaptoSphere filter and loading the PNG image, but the particles still appear untextured.

Ha, got it.

Sadly, even with the “GlyphWithCustomSource” this is not supported yet.  
It should be pretty simple to add by keeping the source array in the data.

Ok, I see, thanks. I wasn’t sure if I missed something. Should I open a feature request for this?
