[osg-users] Help with OSG_OPTIMIZER

[maya leonard]

Hi Robert,

I'm looking for TriangleLists that do not reproduce the same vertices
in VertexArray.

---------------------------------------------
For example I want this:

DrawElementsUInt TRIANGLES 5766
{
2 0 1 2 1 3 1 2 4 1
}

VertexArray Vec3Array 1024
{
-291.43 -202.75 266.13
-272.63 -202.75 267.03
-253.83 -202.75 265.69
-235.03 -202.75 267.56
-235.03 -202.75 297.56
...
}

---------------------------------------------

but I'm getting this:

DrawElementsUInt TRIANGLES 5766
{
0 1 2 3 4 5 6 7 8 9
}

VertexArray Vec3Array 1024
{
-253.83 -202.75 265.69
-291.43 -202.75 266.13
-272.63 -202.75 267.03
-253.83 -202.75 265.69
-272.63 -202.75 267.03
-235.03 -202.75 267.56
-272.63 -202.75 267.03
-253.83 -202.75 265.69

....
}

Thank you,

Maya


Hi Maya,

What do you mean by unique?

Robert.
