Phong shading is an improvement on Gouraud shading, and was one of the first computer shading models developed after the basic flat shader, greatly enhancing the appearance of curved surfaces in renders. Shaders are most commonly used to produce lit and shadowed areas in the rendering of 3D models.
Away3D is an open-source ActionScript 3 engine for developing interactive 3D graphics within Adobe Flash Player and Adobe AIR. Away3D runs on current web browsers utilizing the Adobe Flash Player, and uses Stage3D for GPU-accelerated rendering. [citation needed] The engine can render 3D models and perform various other 3D computations.
Some 2.5D games, such as 1993's Doom, allow the same entity to be represented by different sprites depending on its rotation relative to the viewer, furthering the illusion of 3D. Fully 3D games usually present world objects as 3D models , but sprites are supported in some 3D game engines , such as GoldSrc [ 17 ] and Unreal , [ 18 ] and may be ...
The first step is to find the coordinates of the object as seen from the light, as a 3D object only uses 2D coordinates with axis X and Y to represent its geometric shape on screen, these vertex coordinates will match up with the corresponding edges of the shadow parts within the shadow map (depth map) itself. The second step is the depth test ...

Shadow volume is a technique used in 3D computer graphics to add shadows to a rendered scene. It was first proposed by Frank Crow in 1977 [1] as the geometry describing the 3D shape of the region occluded from a light source. A shadow volume divides the virtual world in two: areas that are in shadow and areas that are not.
Gouraud-shaded triangle mesh using the Phong reflection model. Gouraud shading (/ ɡ uː ˈ r oʊ / goo-ROH), named after Henri Gouraud, is an interpolation method used in computer graphics to produce continuous shading of surfaces represented by polygon meshes.
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.
