An architectural render showing different rendering styles in Blender, including a photorealistic style using Cycles Lunar Crater Radio Telescope conceptual design with the Moon and Earth rendered in Blender. Blender includes three render engines since version 2.80: EEVEE, Workbench and Cycles. Cycles is a path tracing render engine.
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]
The process makes rendering objects quicker and more efficient by reducing the number of polygons for the program to draw. For example, in a city street scene, there is generally no need to draw the polygons on the sides of the buildings facing away from the camera; they are completely occluded by the sides facing the camera.
LightWave is a software package used for rendering 3D images, both animated and static. It includes a fast rendering engine that supports such advanced features as realistic reflection, radiosity, caustics, and 999 render nodes. The 3D modeling component supports both polygon modeling and subdivision surfaces.
Rendering in passes is based on a traditions in motion control photography which predate CGI. As an example, for a visual effects shot, a camera could be programmed to move past a physical model of a spaceship in one pass to film the fully lit beauty pass of the ship, and then to repeat exactly the same camera move passing the ship again to ...
Surface rendering visualizes a 3D object as a set of surfaces called iso-surfaces. Each surface has points with the same intensity (called an iso-value). This technique is usually applied to high contrast data, and helps to illustrate separated structures; for instance, the skull can be created from slices of the head, or the blood vessel ...
In computer graphics and computer vision, image-based modeling and rendering (IBMR) methods rely on a set of two-dimensional images of a scene to generate a three-dimensional model and then render some novel views of this scene.
