fuzzy point display

Hi all,

i am not sure if it is a bug, my graphic card (open GL problem...?) or simply just me doing something wrong...

i made a little animation along a pathline (with the horster camera control) and fuzzy points "jumping".

the blurryness size is according to the distance to the camera location.

while animating the camera i get from certain angles a weird black circle around the fuzzy part that covers the points behing them...

i guess that the blurry point display works similar to scattering proxys when rendering...and somehow the alpha channel doesn't work from some angles....but i could not figure out a rule yet....

i am working in rhino 5 newest release and grasshopper 0.9.0012.

NVIDIA GeForce GTX 260/PCIe/SSE2, OpenGL 3.3.0

is there maybe a way to fix that myself?

thanks in advance

Daniela

Hi Daniela,

the blurry dots are drawn back to front to avoid this kind of clipping, but unfortunately only within a single list. So if you draw more than one list of fuzzy points then they will tend to obscure each other resulting in these horrible clipping artefacts.

There's little I can do about this for now, we'll need to take a deeper look at sprite drawing in Rhino5, see what we can improve.
