Distributed scene rendering

Short answer

Distributed scene rendering divides rendering work among networked computers (a render farm) by assigning frames or image tiles. Nodes render independently and a master assembles the final output, reducing total time.

Explain distributed scene rendering in brief.

Distributed scene rendering is the technique of dividing the work of rendering a complex scene or animation among several computers (or processors) connected in a network, so that the image is produced faster.

  • The scene (or the animation sequence) is divided into parts: different frames go to different machines, or one frame is split into regions/tiles or by objects.
  • Each node renders its part independently, using the scene description sent to it.
  • A master node collects the partial results and assembles the final image or video.
  • This is also called a render farm; it is widely used for film animation, where one frame can take hours on a single machine.
          Master
        /   |    \
   Node1  Node2  Node3   (each renders its frames/tiles)
        \   |    /
       Combined output

The main issues are load balancing and communication cost.
