Hey guys,
since the revision above i get the following exception in the curve class while settings up the index buffer:
[java]SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,6,main]

At line 125 in the Curve.java the following changes were made:
previous:
[java]this.setBuffer(VertexBuffer.Type.Index, 3, indices);[/java]
current:
[java]this.setBuffer(VertexBuffer.Type.Index, (spline.getControlPoints().size() - 1) * nbSubSegments * 2, indices);[/java]
Now i always get the “not between 1 and 4”-Exception. My splines can have any number of control points.
Any ideas what to do?
Regards
Moe

you’re 373 revisions late, it’s been fixed 
Well ok,
but if i update to rev. 7462 the line still looks like that:
[java]this.setBuffer(VertexBuffer.Type.Index, (spline.getControlPoints().size() - 1) * 2, indices);[/java]
Edit:
I just did a complete checkout but the problem still exists.
oh yeah you’re right there is still the error in createLinearMesh(), and the buffer was allocated to 3 instead of 2
Sorry about that, thanks for the report it’s fixed in last revision
