In photo editing or photography post-production, a drop shadow may be added right beneath a model or product in the image. It is used to create contrast between the background and the subject. To add a drop shadow, retouchers use graphic editing tools like Adobe Photoshop. Drop shadows are often used as a visual effect in e-commerce.
In computer graphics, a texture atlas (also called a spritesheet or an image sprite in 2D game development) is an image containing multiple smaller images, usually packed together to reduce overall dimensions. [1] An atlas can consist of uniformly-sized images or images of varying dimensions. [1]
Pixel shaders range from simply always outputting the same color, to applying a lighting value, to doing bump mapping, shadows, specular highlights, translucency and other phenomena. They can alter the depth of the fragment (for Z-buffering), or output more than one color if multiple render targets are active. In 3D graphics, a pixel shader ...
Subsurface scattering is an indirect form of reflection where some of the light is transmitted into a semi-transparent material, scattered under the surface and bounced back out again.
Scene with shadow mapping Scene with no shadows. Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics.This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces."
Isometric video game graphics are graphics employed in video games and pixel art that use a parallel projection, but which angle the viewpoint to reveal facets of the environment that would otherwise not be visible from a top-down perspective or side view, thereby producing a three-dimensional (3D) effect.
Diffuse Color G-Buffer Z-Buffer Surface Normal G-Buffer Final compositing (to calculate the shadows shown in this image, other techniques such as shadow mapping, shadow feelers or a shadow volume must be used together with deferred shading).
Self-Shadowing is a computer graphics lighting effect, used in 3D rendering applications such as computer animation and video games.Self-shadowing allows non-static objects in the environment, such as game characters and interactive objects (buckets, chairs, etc.), to cast shadows on themselves and each other.
