2D Animation Basics UNDER REVIEW
Feb 15 2013 10:30 PM | Posted By Paul Rayman
in Graphics Programming and Theory
A good example of 2D animation is classic cartoons – multiple pictures of Mickey Mouse or Donald Duck alternating over time and producing the effect of moving objects. Modern 2D animation software allows creating animation much easier though, without making oodles of frames.

GPGPU image processing basics using OpenCL.NET UNDER REVIEW
Feb 15 2013 10:07 PM | Posted By Ilya Suzdalnitski
in Graphics Programming and Theory
OpenCL is a cross-platform framework used mostly for GPGPU (General-purpose computing on graphics processing units). There are plenty of tutorials available on image processing with OpenCL using C/C++, however there's not much information that would cover OpenCL image processing with .NET.I won't go into details about OpenCL kernels/queues/etc. (there's plenty of information available on the in...

Dynamic Resolution Rendering
Sep 25 2011 10:00 PM | Posted By Doug Binks
in Graphics Programming and Theory
Brought to you by the Intel® Visual Computing Developer Community | Download the source code | Watch the videoIntroduction The resolution selection screen has been one of the defining aspects of PC gaming since the birth of 3D games. In this whitepaper and the accompanying sample code, we argue that this no longer needs to be the case; developers can dynamically vary the resolution o...

A Simple and Practical Approach to SSAO
May 25 2010 07:41 AM | Posted By José María Méndez
in Graphics Programming and Theory
IntroductionGlobal illumination (GI) is a term used in computer graphics to refer to all lighting phenomena caused by interaction between surfaces (light rebounding off them, refracting, or getting blocked), for example: color bleeding, caustics, and shadows. Many times the term GI is used to refer only to color bleeding and realistic ambient lighting. Direct illumination – light that comes dir...
Deferred Rendering Demystified
Mar 01 2010 10:46 AM | 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 03:32 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 09 2009 10:44 PM | 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 10:34 AM | 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 08:23 AM | 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 01:08 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 04:07 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 04:00 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 03:00 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

Soft-Edged Shadows
Jan 18 2005 10:23 AM | Posted By Anirudh.S Shastry
in Graphics Programming and Theory
IntroductionOriginally, dynamic shadowing techniques were possible only in a limited way. But with the advent of powerful programmable graphics hardware, dynamic shadow techniques have nearly completelyreplaced static techniques like light mapping and semi-dynamic techniques like projected shadows. Two popular dynamic shadowing techniques are shadow volumes and shadow mapping. A closer lookThe...
