[Question] Export to Mesh

[gcrois]

What is the easiest way to convert a NeRF generated using this project into a mesh (.obj, for example)?

[galmetzer]

Good question, A common technique is to use marching cubes. We observed it doesn't work so well. Furthermore, coloring the mesh from the radiance field is not as simple as querying the radiance field at vertices, as pixel values are computed by integrating over an entire ray. If you still want to give it a try you can probably use the implementation with MC from Stable dreamfusion

@galmetzer Hi, I am trying to migrate the export_mesh implementation in Stable Dreamfusion to this project. However, I got the right geometry of the mesh but wrong albedo texture like this. Do you know why it happened?

hi I tried to use stable dreamfusion's export_mesh function with shape-guided NeRF generation here, but the output mesh doesn't make sense. May I ask did you run this on shape-guided NeRF or unconstrained NeRF?
