Are the data scattered or on a grid? If they are gridded, you should
import them that way. You can always do point visualization (e.g.,
ShowPositions).
How are visualizing the data right now, glyphs? If the glyphs are of
higher quality and with 15K points, that may be a lot of triangles to
render, depending on the platform you are using, whether you are using
hardware rendering, etc.

Subject: [opendx-users] Image Rendering
Hi,
I am trying to import (x,y,z) data that represents the point on the 3D
grid. Then display image according to the data. As a matter of fact, the
input file is simple text and each (x,y,z) represents a point of one
sphere.
Input file looks like this
0 0 1
0 0 -1
0 1 0
0 -1 0
1 0 0
-1 0 0
...
...
...
Input file contains about 15000 x y z values.
I imported it using SpreadSheet format but rotating/panning takes too
much time. I hope to see real time interaction but it simply takes a bit
longer. Please let me know if there is better way to do this task.
I guess, I should have used 'Scattered Point' import but I am not sure
and I don't know how I should set the DataPrompter.
Any response to this would be greatly appreciated.
Regards,
JW Park
