Simulation of two fluids with different viscosities. The development of fluid animation techniques based on the Navier–Stokes equations began in 1996, when Nick Foster and Dimitris Metaxas [3] implemented solutions to 3D Navier-Stokes equations in a computer graphics context, basing their work on a scientific CFD paper by Harlow and Welch from 1965.

Real-world subsurface scattering of light in a photograph of a human hand Computer-generated subsurface scattering in Blender. Subsurface scattering (SSS), also known as subsurface light transport (SSLT), [1] is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface potentially at a ...
When a shader computes the result color, it uses a lighting model to determine the amount of light reflected at specific points on the surface. Different lighting models can be combined with different shading techniques — while lighting says how much light is reflected, shading determines how this information is used in order to compute the ...
Bump mapping is a technique in computer graphics to make a rendered surface look more realistic by simulating small displacements of the surface. However, unlike displacement mapping, the surface geometry is not modified. Instead only the surface normal is modified as if the surface had been displaced.
The illumination models listed here attempt to model the perceived brightness of a surface or a component of the brightness in a way that looks realistic. Some take physical aspects into consideration, like for example the Fresnel equations, microfacets, the rendering equation and subsurface scattering.
If one is defined, a volume shader describes the light interaction as it passes through the volume of the mesh. Light may be scattered, absorbed, or even emitted [clarification needed] at any point in the volume. [47] The shape of the surface may be altered by displacement shaders. In this way, textures can be used to make the mesh surface more ...
Across a series of 10 large-scale paintings, artist Calida Rawles captures the movement of women and girls suspended in water in her exhibition “A Certain Oblivion.” The painter submerging ...
3D animation of ambient occlusion enabled on the animation to the right. In the absence of hardware-assisted ray traced ambient occlusion, real-time applications such as computer games can use screen space ambient occlusion (SSAO) techniques such as horizon-based ambient occlusion including HBAO and ground-truth ambient occlusion (GTAO) as a faster approximation of true ambient occlusion ...
