Does anybody know what these numbers represent?? (From the example file smilly.dat)
Code: Select all
vertexCount 24

this is not a file format, I simple wrote that dat from an editor do that I can mak eteh totorual.

physics library usuallly do not have file format.
if you want a file format for the engine, look at the dScene library.
you can use to save mesh. It has a 3dsMax plugin

In general people how use a physics library already has their own graphics engine with thier own file format.
do you have a Game engine or a graphics engine?

First part of the file have 8 rows, my guess is that first 3 are vertex position, then second 3 normals and last 2 are texcoords.
Each line is one vertex.
Last line should be obvious.

are you using core 300?

if so now there is a .OFF file save and load function in NewtonMesh, maybe you can use that to load .OFF files as NewtonMesh.
later I will modify the demos so that is use .OFF files.
