English: A 3D rendered image using path tracing, rendered by Blender's Cycles renderer. The smoothness of the meshes used for the cows has been increased using subdivision . The scene uses very simple lighting, and uniform background colors, to make it easier to interpret differences in global illumination when comparing to versions of the ...

Art or Illusion uses multi threading for rendering images and it provides several options for lighting. [13] The core software package comes with two built in renderers: The Ray Tracer renderer provides anti-aliasing , soft shadows, depth of field, transparent background, photon mapping caustics and subsurface scattering .
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite.
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]
In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. For example, the interior of a tube is typically more occluded (and hence darker) than the exposed outer surfaces, and becomes darker the deeper inside the tube one ...
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
One key disadvantage of deferred rendering is the inability to handle transparency within the algorithm, although this problem is a generic one in Z-buffered scenes and it tends to be handled by delaying and sorting the rendering of transparent portions of the scene. [6]
