number of primitives with p5sunflow
Dec 27th, 2009, 8:06pm  

hi all,

i am rendering some scene with a lot of polygons in p5sunflow and after a while, sometimes 20 rendered frames or 200 frames, the program stops and this is what i get.

is this because of the number of polygons or?
any help would be really appreciated.

thanks.

i am still trying to play around with this... and i can't find the solution yet.
does anyone know if there is a way to limit the scene in processing, or this needs to be done through sunflow commands?

if i limit the scene to a cube or ball, i have a feeling that the 'infinity...' messages will disappear?

thanks

Can you post the processing code.

I have had similar issues before and it't usually during the setup() of the code.

hey guys,

what version of processing are you using to get p5sunflow running. i have 1.0.7 installed and its telling me that p5sunlow needs an update in order to work with my processing version.

thanks!

// update
