High-performance computing cluster consisting of networked computers dedicated to rendering CGI, visual effects, and animation frames – distributes complex computational tasks across multiple machines to drastically reduce rendering time for feature film and television VFX production.
What is a Render Farm?
A Render Farm is a cluster of networked computers specifically designed for rendering CGI, VFX, and animation. By distributing the computational workload across hundreds or thousands of processors, rendering times are reduced from years to hours.
