How to convert .obj to .ply, with colored vertices and triangular faces open the meshlab and import *.obj file centralize the mesh Filters -> Normals, Curvatures and Orientations -> Transform: Move, Translate, Center -> check translate center of bbox to the origin -> Apply subdivide mesh Filters -> Remeshing, Simplication and Reconstruction -> Subdivision Surfaces:Midpoint -> Adjust Iterations and Apply colorize vertexs using uv texture Filters -> Color creation and Processing -> Transfer Color:Texture to vertex triangularize faces Filters -> Polygonal and Quad Mesh -> Turn in to a Pure-Triangular Mesh Export mesh as ply File -> Export mesh as -> ply -> Check only color (vertice), Normal (vertice), Binary encoding.
