Polygon hatch problem for angles 90-180 and 270-360

Reported by: havatv Owned by: tbonfort
Priority: highest Milestone: 6.2 release
Component: Renderer API Version: svn-trunk (development)
Severity: major Keywords: hatch, rendering
Cc: havatv

Description

After #3847 (global origin for polygon patterns) was fixed in r12807, polygon hatches do not render correctly for angles between 90 and 180 and 270 and 360 (and 0 to minus 90, ...). I attach some illustrations.

  • status changed from assigned to closed
  • resolution set to fixed

fixed in r12816, my bad I hadn't retested >90 angles after adding a small 1.0/sin() optimization.

Seems to work now. No performance problems. Great!
