Which data format is commonly used for meshes intended for visualization in VIM?

• A. LAS/LAZ
• B. E57
• C. PLY
• D. OBJ/FBX

Answer: (D)

When you want a mesh to look right in visualization work, you need a format that cleanly encodes the surface geometry and, if needed, how it should look (materials and textures). OBJ and FBX are standard for this because they store polygonal mesh data—vertices, faces, normals, and texture coordinates—and they can carry material information. This makes them immediately usable across visualization tools and pipelines, which is exactly what you want for VIM workflows. The other formats shown are more focused on point clouds or have less direct support for full textured meshes: LAS/LAZ are LiDAR point clouds, E57 mixes point clouds with imagery, and PLY is common in research and can represent meshes but isn’t as universally streamlined for visualization as OBJ/FBX. So OBJ/FBX are the go-to choices for meshes intended for visualization.
