Ah yes, I fixed that last night. I should have used a transaction to modify the image traverser in objviewer.py, while instead I just reassigned the pointer--the FPE was caused by a parallel hazard.

I just committed r1372 which comments out this change (but shows how to modify other state in the viewer if you want to). Neat that you're using the python interface...

Hi Abe. I have compiled Manta and tried to run objviewer.py, but I get floating point exceptions here:

0x00002aaaad8a18b0 in Manta::TiledImageTraverser::renderImage (this=0xd99e20, context=@0x41200d50, image=0x56b220) at /home/rubinste/packages/Manta/Manta/Engine/ImageTraversers/TiledImageTraverser.cc:136

...
    for(int assignment = s; assignment < e; assignment++){

-->    int xtile = assignment/ytiles;

DDD shows that assignment == 0 and ytiles == 0

I run "python SwigInterface/objviewer.py -f file.obj" .

Any idea what I am doing wrong ?

Greetings

Dmitri
