Output of ReconstructMesh

[Harr7y]

Why the outputs of ReconstructMesh scene_dense.mvs -p scene_dense.ply are "scene_dense_mesh.mlp", "scene_dense_mesh.ply", "scene_dense_mesh_raw.ply"? I didn't get the "scene_mesh.mvs" for RefineMesh .

cmake -DCMAKE_BUILD_TYPE=Debug ..
The repo is built in a debug mode, otherwise, I will get an error "Assertion failed: (facets.empty() && inter.type == intersection_t::VERTEX && inter.v1 == vi)", cmake -DCMAKE_BUILD_TYPE=Release .. doesn't work.

First of all pls build in release mode.
Second you do not need an mvs file from mesh. The mesh and scene-dense.mvs are what you need

Thanks for your reply.

1. How to build in release mode??
   cmake -DCMAKE_BUILD_TYPE=Release .. doesn't work.
2. So what should I feed into RefineMesh?
   replace RefineMesh **scene_mesh.mvs** -m scene_dense_mesh.ply -o scene_dense_mesh_refine.mvs with RefineMesh **scene_dense.mvs** -m scene_dense_mesh.ply -o scene_dense_mesh_refine.mvs ? It didn't work.
3. How can we convert export the PLY projects to MVS or OBJ formats?

The second issue, you may refer to #1058.

Thanks for your advice. But I want to refine the mesh because the generated mesh (through ReconstructMesh) is coarse. I want it to be finer.

RefineMesh scene_dense.mvs -m scene_dense_mesh.ply

[Harr7y]

Thanks for your reply.
I have one more question, how to convert the final '.mvs' format (scene_dense_mesh_refine.mvs) into '.ply' format.
