Hello, I started using Babylon.js for a new project and am impressed how easy it is to get started! My goal is to create a gcode viewer (files used for 3d printing instructions). The gcode basically contains the path the printer takes and the problem is that these can get really big. So I created …

Maybe you could try serializing the scene after merge meshes and reuse this later on ?

The tube has by default numerous vertices. Did you try with a lighter model like a ribbon or a custom extruded mesh from a simple shape (triangle ?) ?

Thanks for your suggestions! @sebavan This unfortunately isn’t possible, because the gcode on which the model is based is uploaded by the user. @jerome I used tesselation: 3 to make the tube essentially an extruded triangle, but I tried extruding a triangle using the ExtrudeShape function and go…

What does a sample of your dataset look like? Could this be done with volumetric rendering?

[image] jerome: 200K three-tessellated cylinders : https://playground.babylonjs.com/#SE22AV#18 I’m getting 60fps on my phone.

Many models are composed of multiple meshes. Can we create SPS and ensure their relative positions are correct? And its animation? Can each particle carry an animation? The other is to change the color and transparency of the model;Babylon has no concept of object (many sub grids are combined into o…

you could use particle parenting to set animations of articulated parts : https://playground.babylonjs.com/#SE22AV#23 I agree this can be quite complex to implement and compute then.
