Hi,

I'm attempting to plot the path of a moving object by either using a THREE.Line or a series of Points.
The problem I have is that it appears you cannot dynamically alter geometry.
Am I incorrect in believing this ?
I know you have the Geometry.dynamic flag, dirtyVertices and so forth, but this all assumes you have a fixed number of vertices.
I need to add to my vertices each frame (or perhaps every second to keep the number of verts down) so that a dynamic path is shown on the path of the object.

Anyone have any ideas ? tackled something similar ? or am I wrong in the dynamic nature of geometry?

Thanks in advance.
