Rendering is the process of generating a final
product from a specific type of
. The term usually applies to graphics and video, but it can refer to audio as well.
3D graphics are rendered from basic three-dimensional models called wireframes. A wireframe defines the shape of the model, but nothing else. The Rendering process adds surfaces, textures, and lighting to the model, giving it a realistic appearance. For example, a 3D drawing
program may allow you to add different colors, textures, and lighting sources to a 3D model. The Rendering process applies these settings to the object.
Thanks to the power of modern
, 3D image Rendering is often done in
. However, with high-resolution models, surfaces and lighting effects may need to be rendered using a specific "Render" command. For example, a CAD program may display low-resolution models while you are editing a scene, but provide an option to render a detailed model that you can
@swift_xregum What is an example of Rendering? The definition of a Rendering is a translation, interpretation, or a drawing. An example of a Rendering is an artist's interpretation of a scene. I use the term "to render" in a very literal sense, as in appl— blueartistic813 🇺🇦 (@SteamPoweredDM) Dec 21, 2021
3D animations and other types of video that contain
often need to be rendered before viewing the final product. This includes the Rendering of both 3D models and video effects, such as filters and transitions. Video clips typically contain 24 to 60 frames per second (
), and each
must be rendered before or during the export process. High-resolution videos or movies can take several minutes or even several hours to render. The Rendering time depends on several factors including the
, frame rate, length of the video, and processing power.
While video clips often need to be pre-rendered, modern GPUs are capable of Rendering many types of 3D graphics in real-time. For example, it is common for computers to render high-definition video game graphics at over 60 fps. Depending on the graphics power, a game's frame rate may be faster or slower. If the GPU cannot render at least 30 frames per second, the video game may appear choppy.
Like video effects, audio effects can also be rendered. For example, a
application may include effects like reverb, chorus, and auto-tune. The
may be able to render these effects in real-time, but if too many tracks with multiple effects are being played back at once, the computer may not be able to render the effects in real-time. If this happens, the effects can be pre-rendered, or applied to the original audio track. All effects are rendered when the final mix is exported or "
" as an audio file.
