Deferred Rendering Demystified
Mar 01 2010 04:46 PM | Posted By Noam Gat in Graphics Programming and Theory
Deferred Rendering is an alternative rendering approach that has many advantages. The theory behind it has been discussed to great detail, but implementing a deferred renderer is still a puzzling task. This article discusses the technique from a design standpoint, suggesting how a graphics engine can be structured to easily integrate a deferred rendering approach, and is accompanied by an open...
Cube Map Rendering Techniques for Direct3D10
Feb 01 2010 09:32 AM | Posted By Vincent Prat in Graphics Programming and Theory
Unlike DirectX 9 which allows you to only render cube maps in 6 passes, DirectX 10 offers different ways to do it more efficiently: geometry shaders & improvements in the geometry instancing API offer single pass alternatives to cube map rendering. This article presents 3 algorithms as well as their drawbacks and advantages
Walls and Shadows in 2D
Nov 10 2009 04:44 AM | Posted By Scott Mayo in Graphics Programming and Theory
This article presents a technique for determining visibility information suitable for arbitrary closed two-dimensional maps at interactive rates (each pass of the algorithm will usually take less than a second); as such it can be most useful in turn-based games, or games where extremely fast visibility recalculation is not required. The technique can also be used to handle illumination and shad...
Cellular Textures, the light speed approach
Aug 10 2009 04:34 PM | Posted By Carsten Przyluczky in Graphics Programming and Theory
Procedural texture generation is a very flexible and powerful technique, and the results are awesome looking textures that only require a few hundred bytes. Cellular textures is one such method. This article will describe how they are generated starting with a simple but slow algorithm. Then it will look over an advanced algorithm that takes linear time and provides some nice extra features
Image Space Lighting
Jun 11 2009 02:23 PM | Posted By David Maletz in Graphics Programming and Theory
An explanation of the theory behind and implementation of image space lighting, a technique that utilizes deferred lighting and rasterization to efficiently and accurately render hundreds of light sources in real time. This technique allows for complex lighting environments found in scenes with lampposts, lanterns, cities at night, light-emitting particle effects and other scenes with many ligh...
Rendering Water as a Post-process Effect
Jun 04 2009 07:08 PM | Posted By Wojciech Toman in Graphics Programming and Theory
This article presents a screen-space approach to water rendering. The technique makes water look realistic by focusing on aspects rarely taken into account like colour extinction. It is based on observation rather than on mathematical model.
Moving Noise
May 27 2009 10:07 AM | Posted By Dan Nielsen in Graphics Programming and Theory
This feature introduces a drop-in Perlin noise variant useful for quickly generating organic procedural functions that change over time. You can use it to create scenes, textures, animations, and sounds. If you modify it or do something interesting with it, the author would love to know
Dynamic 3D Scene Graphs
Dec 10 2008 10:00 AM | Posted By Andrew Top in Graphics Programming and Theory
Scene graphs used in most games today are actually scene trees, defined offline by artists. Interesting features can be achieved by instead defining offline a set of rules that explain how to generate a scene tree. By dynamically building the scene tree from a set of rules at run-time, we can support true scene graphs (scene graphs with cycles in them) as well as the ability to host environme...
Computation of Bounding Primitives on the GPU
Nov 12 2008 09:00 AM | Posted By Philip Rideout in Graphics Programming and Theory
Nowadays it's becoming fashionable to use GPU's for purposes other than pure graphics. Learn a sneaky trick that leverages the GPU's horsepower to efficiently compute an axis-aligned bounding box. Includes sample code for DirectX 10, but this method can be used with other API's as well
