Autodesk Arnold (also known as simply Arnold) is a computer program for rendering three-dimensional, computer-generated scenes using unbiased, physically-based, Monte Carlo path tracing techniques. Created in Spain by Marcos Fajardo, it was later co-developed by his company Solid Angle SL (now owned by Autodesk ) and Sony Pictures Imageworks .
During 2009-2010, SPI made transition from traditional biased, multi-pass rendering system to a largely singlepass, global illumination system incorporating modern ray-tracing and physically based shading techniques. They have achieved that with Arnold Renderer, an unbiased stochastic ray tracer.
This page provides a list of 3D rendering software, the dedicated engines used for rendering computer-generated imagery. This is not the same as 3D modeling software , which involves the creation of 3D models, for which the software listed below can produce realistically rendered visualisations.
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.
The word "rendering" (in one of its senses) originally meant the task performed by an artist when depicting a real or imaginary thing (the finished artwork is also called a "rendering"). Today, to "render" commonly means to generate an image or video from a precise description (often created by an artist) using a computer program. [1] [2] [3] [4]
Modo's renderer is multi-threaded and scales nearly linearly with the addition of processors or processor cores. That is, an 8-core machine will render a given image approximately eight times as fast as a single-core machine with the same per-core speed. Modo runs on up to 32 cores and offers the option of network rendering. [citation needed]
Unbiased rendering in computer graphics refers to techniques that avoid systematic errors, or biases, in the radiance approximation of an image. This term specifically relates to statistical bias, not subjective bias. Unbiased rendering aims to replicate real-world lighting and shading as accurately as possible without shortcuts.
Rendering – Houdini ships with SideFX's rendering engines Mantra and Karma; Houdini Indie licence and up support 3rd party rendering engines, such as Renderman, Octane, Arnold, Redshift, V-ray, Maxwell(soon). Volumetrics – With its native CloudFx and PyroFx toolsets, Houdini can create clouds, smoke and fire simulations.
