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.
It is possible to modify the depth map test to produce shadows with a soft edge by using a range of values (based on the proximity to the edge of the shadow) rather than simply pass or fail. The shadow mapping technique can also be modified to draw a texture onto the lit regions, simulating the effect of a projector. The picture above captioned ...
Parallax mapping is essentially a method by which rough or uneven surfaces on a 2D texture can be "pulled out" to take on the appearance of a 3D surface. Technically, this is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface ...
On October 22, 2009, Sony Online Entertainment released EverQuest II: The Complete Collection, a retail bundle which included the base game, the first three adventure packs, and the first six expansions up to The Shadow Odyssey. [45] The package also came with 500 Station Cash to use in the in-game digital store, and 60 days of free game time. [46]
SSAO component of a typical game scene. The algorithm is implemented as a pixel shader, analyzing the scene depth buffer which is stored in a texture. For every pixel on the screen, the pixel shader samples the depth values around the current pixel and tries to compute the amount of occlusion from each of the sampled points.
In general, a drop shadow is a copy in black or gray of the object, drawn in a slightly different position. Realism may be increased by: Darkening the colors of the pixels where the shadow casts instead of making them gray. This can be done with alpha blending the shadow with the area it is cast on. Softening the edges of the shadow.
Shadow Warrior Classic Complete is the PC version of Shadow Warrior that was released onto GOG.com and includes the main game and both expansion packs, Wanton Destruction and Twin Dragon. While the Steam version is free (see below), the GOG.com version used to be paid, and has a digital copy of the game's soundtrack in MP3 and FLAC and the game ...
