Rendering is usually limited by available computing power and memory bandwidth, and so specialized hardware has been developed to speed it up ("accelerate" it), particularly for real-time rendering. Hardware features such as a framebuffer for raster graphics are required to display the output of rendering smoothly in real time.
English: A 3D rendered image using path tracing, rendered by Blender's Cycles renderer. The smoothness of the meshes used for the cows has been increased using subdivision . The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination when comparing to versions of the ...
Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object.
Multiple GPUs are also supported (with the notable exception of the EEVEE render engine [49]) which can be used to create a render farm to speed up rendering by processing frames or tiles in parallel—having multiple GPUs, however, does not increase the available memory since each GPU can only access its own memory.

A photorealistic 3D render of 6 computer fans using radiosity rendering, DOF and procedural materials. Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. [1]
The plan for LuxRender 2.0 was defined during the 2013 summer and one of the major components is a new engine based on the C++ and Python APIs. The old C API suffered from many limitations when it came to modern features like dynamic scene editing and interactive rendering, so it was decided to write a completely new API instead of improving ...
Physically based rendering (PBR) is a computer graphics approach that seeks to render images in a way that models the lights and surfaces with optics in the real world. It is often referred to as "Physically Based Lighting" or "Physically Based Shading".
After E3 2003, Valve released a demo movie of their Source engine rendering a cityscape in a high dynamic range. [9] The term was not commonly used again until E3 2004, where it gained much more attention when Epic Games showcased Unreal Engine 3 and Valve announced Half-Life 2: Lost Coast in 2005, coupled with open-source engines such as OGRE ...
