Indigo4 (public beta)


Indigo4 (public beta) visionabile e scaricabile sul FORUM a QUESTO LINK

La caratteristica principale che contraddistingue questa beta è naturalmente il pure (multi-)GPU rendering. Utilizzando driver OpenCL è stato infatti possibile assicurare una compatibilità con un’ampia gamma di GPU, includendo AMD, Nvidia ed Intel.

Ecco la lista di nuove features:

  • General optimizations and rendering speedups:
  • Most scenes should render faster on the CPU.
  • MLT should be a lot faster for simple scenes now.
  • OpenGL viewport is a lot faster
  • Sped up rendering double-sided thin material a lot.
  • Optimized object tree building
  • Rewrote much of Indigo’s subdivision and displacement
  • New image saving options. (check out the ‘Image Saving’ tab in the options dialog)
  • Added pixel info picker to toolbar
  • Added a detachable material preview widget
  • Oren-Nayar: Added new implementation of the more accurate model, replacing the ‘qualitative’ model that was being used before.
  • Added measured BRDF support
  • Added Fast-SSS material

More information about the new GPU rendering mode

Features not currently supported in GPU rendering mode (we’re working on these and they will be supported as soon as possible)
* Architectural glass
* Double-sided thin material
* Glossy transparent material
* Normal maps
* Light layers

Features not currently supported in GPU rendering mode, that probably won’t be available in the initial 4.0 release but later in the 4.x series:
* Sub-surface scattering / participating media
* Bidirectional path tracing
* Other render modes / channels: material ID, foreground alpha, depth and shadows
* Sphere primitives

Known issues with GPU rendering:
* Some realtime changes in GPU rendering mode may crash Indigo
* Max path depth is limited to around 8 bounces currently
* Sphere primitives not supported currently
* Sky colour is slightly different on GPU
