Hi, you can convert obj to ply and/or stl using e.g. free MeshLab. TetGen has great documention http://wias-berlin.de/software/tetgen/1.5/doc/manual/manual006.html#sec88 |

@korzen Oh yes, I used and btw, if I want to realize dynamic tetrahedralization and fracture like this -> Adaptive Tetrahedral Meshes for Brittle Fracture Simulation, I wonder if there is any convenient approach for Sorry to bother you for my personal problems~ I'm new to physics based animation, and really appreciate your help! ~(≥▽≤)/~ |

The simple answer is: because nobody had time to implement this yet ;-) |

@korzen I feel so sad that I still can not convert correctly using TetGen. T.T in fact, I can successfully convert some simple model like my models: I really wonder why ToT... Apologize to bother you but could you please offer me some advice for my confusion? Thanks a lot! |

I'm no expert in using TetGen but maybe TetWild can give you better results: |

Hi~
I'm working on a FEM simulation on
PositionBasedDynamics
and get trapped by the right way to convert aobj
mesh to atet model
.In the example scene
DeformableSolidCollisionScene
, I learned that.ele
file and.node
file are required to get a tetrahedron model, they're produced by the toolTetGen
.But unfortunately, I found that
TetGen
seems not to support a direct approach to convert a.obj
file to.ele
and.node
TetGen doc, it seems only support.off
.ply
.stl
.mesh
. And there is a commandtetgen -pqa5000.0 Armadillo_UV_low.off
at the last line of the filesarmadillo_4k.ele
andarmadillo_4k.node
, which hints that a.off
is required, but I don't know where can I get the.off
file...So my confusion is that,
TetGen
correctly when working onPositionBasedDynamics
?more specifically,
.off
file?.obj
file or whatever else?TetGen
andPositionBasedDynamics
?Best regards~
