An architectural render showing different rendering styles in Blender, including a photorealistic style using Cycles Lunar Gateway rendering in Blender. Blender includes three render engines since version 2.80: EEVEE, Workbench and Cycles. Cycles is a path tracing render engine. It supports rendering through both the CPU and the GPU.
A distinction is made between real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or animation), and offline rendering (sometimes called pre-rendering) in which images, or film or video frames, are generated for later viewing. Offline rendering can use a slower and ...
In January 1998, a free version of Blender was released on the internet, followed by versions for Linux and FreeBSD in April. [4] Shortly after that, NeoGeo was taken over by another company in parts. This was when Ton Roosendaal and Frank van Beek decided to found a company called Not a Number (NaN) to further market and develop Blender. [3]
Animations for non-interactive media, such as feature films and video, can take much more time to render. [4] Non-real-time rendering enables the leveraging of limited processing power in order to obtain higher image quality. Rendering times for individual frames may vary from a few seconds to several days for complex scenes.
When working with game animations, skeletal 2D animations are commonly created using tools like Spine, DragonBones, Blender COA Tools, Rive, and the built-in Unity editor. The primary benefit of this approach is the ability to reuse images, which reduces the amount of graphics stored in RAM.
Cel shading or toon shading is a type of non-photorealistic rendering designed to make 3D computer graphics appear to be flat by using less shading color instead of a shade gradient or tints and shades. A cel shader is often used to mimic the style of a comic book or cartoon and/or give the render a characteristic paper-like texture. [1]
In real-time computer graphics, geometry instancing is the practice of rendering multiple copies of the same mesh in a scene at once. This technique is primarily used for objects such as trees, grass, or buildings which can be represented as repeated geometry without appearing unduly repetitive, but may also be used for characters.
STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
