• Several cleanups and bug fixes
  • Improved precision of ray intersection with streamlines,
    spheres, and cylinder geometries
  • Fixed address overflow in framebuffer, in practice image size is
    now limited only by available memory
  • Fixed several deadlocks and race conditions
  • Fix shadow computation in SciVis renderer, objects behind light
    sources do not occlude anymore
  • No more image jittering with MPI rendering when no accumulation
    buffer is used
• Improved path tracer materials
  • Also support RGB eta/k for Metal
  • Added Alloy material, a "metal" with textured color
