Hash Fellow robcat2075 Posted February 25, 2011 Hash Fellow Posted February 25, 2011 I manually upped the res on my coin model and reapplied the map for this test before I did the PLY export. I suppose it would be possible for the PLY plugin to be modified to permit more subdivision, perhaps x256? But to really capture per pixel displacement you'd need zillions. I'm wondering... why the bumps? Quote
pixelplucker Posted February 25, 2011 Posted February 25, 2011 Zillions might not really be needed if the variable option could handle higher divisions. Maybe using some sort of smoothing angle to determine the number of faces in a region could dictate the tesselation? Quote
Hash Fellow robcat2075 Posted February 25, 2011 Hash Fellow Posted February 25, 2011 I've tested further and found that something about displacement creation is making the bumps. An object without a displacement map doesn't get the bumps. Here's a test of exporting two grids, the one on the right has a flat gray displacement map on it. Teh bottom two windows are the PLY result imported back in. I've put that in as a "minor" priority AMReport. Quote
pixelplucker Posted February 25, 2011 Posted February 25, 2011 Is there a poly limit with obj files vs ply? Maybe just improving the obj i/o would be a better, more popular and compatible format to go with. An adaptive tessellation based on the angles might work good and have a quad or triangle option as well. Quote

Since you already created a ticket, I would like to add a note to say that AM's ply files are also missing the proper headers. Quote

Is the "header" just boilerplate text? Could you add it in a text editor? Quote
HomeSlice Posted February 26, 2011 Posted February 26, 2011 Unfortunately, the PLY plugin exports a binary file, although technically the ply format ca be either binary or ascii. Quote

If you can point him to some documentation about what a proper PLY header is that might expedite it. Quote
