- Summary: Particle overlay problem with parallel projections
- Component: yt
- Milestone:
- Reporter: dsilvia
- Owner: mturk
- Resolution: None
- Status: new
- Created: 1239128735000000
- Description: Particle overlay is not executed properly when doing parallel projections. Only a fraction of the total particles are plotted. Code errors if a processor doesn't not have any particles to overlay.
Error if processor doesn't have any particles:
Particle bounding box: 0.0 1.0 0.0 1.0 1.5 2.5
Traceback (most recent call last):
Particle px extrema
