This article shows how to create streamlines using the PointCloud class. With the first approach,  you will have full control over the streamlines colors since you can set the RBG color of each the PointCloud's vertexes.

When the entities are very far from the origin their appearance on screen may become very compromised, and the camera may shake badly when moving/rotating the view. Case 1: See the image below of a circle created at (1e9, 1e9, 0) with radius 200:   This is due to the float precision of OpenGL that…
