Manifold Software

We take a triangle mesh "input.obj" and generate a manifold "output.obj". The resolution is the number of leaf nodes of octree. The face number increases linearly with the resolution.

./manifold input.obj output.obj [resolution (Default 20000)]

Simplify Algorithm

Our manifold software generates uniform manifold. For efficiency purpose, a mesh simplification can be used.

./simplify -i input.obj -o output.obj [-m] [-f face_num] [-c max_cost] [-r max_ratio]

-m // turn on manifold check, we don't output model if check fails

-f face_num // add termination condition when current_face_num <= face_num

-c max_cost // add termination condition when quadric error >= max_cost

-r max_ratio // add termination condition when current_face_num / origin_face_num <= max_ratio

Example:

./simplify -i input.obj -o output.obj -m -c 1e-2 -f 10000 -r 0.2
