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 .
This flexibility enables bidirectional path tracing, Metropolis light transport, and many other rendering algorithms that cannot be implemented with tail recursion. [38] OptiX-based renderers are used in Autodesk Arnold, Adobe AfterEffects, Bunkspeed Shot, Autodesk Maya, 3ds max, and many other renderers.
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 naturally simulates many effects that have to be specifically added to other methods (conventional ray tracing or scanline rendering), such as soft shadows, depth of field, motion blur, caustics, ambient occlusion, and indirect lighting. Implementation of a renderer including these effects is correspondingly simpler.

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]
Open Shading Language (OSL) was developed by Sony Pictures Imageworks for use in its Autodesk Arnold Renderer. It is also used by Blender 's Cycles render engine. OSL's surface and volume shaders define how surfaces or volumes scatter light in a way that allows for importance sampling; thus, it is well suited for physically-based renderers that ...
The rasterization step is the final step before the fragment shader pipeline that all primitives are rasterized with. In the rasterization step, discrete fragments are created from continuous primitives. In this stage of the graphics pipeline, the grid points are also called fragments, for the sake of greater distinctiveness.
