23 This file contains a class TriangleIndexVertexArray. I tried using the class with the same name
24 from the BulletX implementation and found it unusable for the purpose of using triangle meshes
25 within BulletX as the implementation was painfully incomplete.
26 The attempt to derive from the original class failed as viable members were hidden.
27 Fiddling around with BulletX itself was not my intention.
28 So I copied the class to the BulletX-plugin and modified it.
29 If you want to fiddle around with it it's up to you to move all this to BulletX.
30 If someone someday implements the missing functionality in BulletX, feel free to remove this class.
31 It's just an ugly hack.
