Hi,

I am trying to draw lines in a 3D display. Currently, I am using a TPolyMarker3D object and the setpoint function. The problem is that once I draw about 600000 or more points (3000 lines with 200 points), the display becomes very slow.

I wanted to know if there already exists some function drawing 3D lines which is better optimized.
Because as I understand it, if the 3D viewer considers every point as a 3D object, he will calculate the rotation for every point instead of simply rotating the "line".
