SARGE animation SDK imports 3D models into OpenGL API-based applications

Mar 31, 2005 | Categories: Applications | Comments

SARGE is an animation SDK that helps you to import object and character animations from 3D modelling software into your own OpenGL API-based application or game engine. It supports import and play of animations with bones using an object’s weightmaps to determine influence of each bone on the animated object, ragdoll physics, child parent hierarchies, interpolation, shaders, and fast object swapping. The downloadable demo is an OpenGL API-based example.

IRIS Explorer V5.2 visual programming environment for OpenGL API accelerated scientific visualizatio

Mar 29, 2005 | Categories: Applications | Comments

IRIS Explorer is a scientific OpenGL API-accelerated data visualization system that features a visual programming interface to you to develop, prototype and build visualization applications quickly and easily. Visualization techniques range from simple graphs to multidimensional animation.The new V5.2 is available for Linux and Mac OS X running X11 (and also Windows, SGI, Sun, HP and IBM systems)

Motion blur effect using the OpenGL API and alpha values

Mar 29, 2005 | Categories: Developers | Comments

This demo with source shows how to create a motion blur effect using the OpenGL API without the accumulation buffer. By rendering the object into a texture you can access the precedent frame, and render it with a lower alpha value. Doing this in a recurrent mode we get a motion blur effect.

3D GO Screen Saver V3.0 using the OpenGL API

Mar 29, 2005 | Categories: Applications | Comments

feature graphic

The GO Screen Saver V3.0 uses the OpenGL API to play GO games in 2D and 3D. Features include camera movements, board tags, board in 2D and 3D, and 3D markers. The GL_ARB_vertex_buffer_objects is used to display stones on the 3D board. This feature can be disabled/enabled in real time. The software also include an OpenGL analyser of OpenGL extension support form your video card.

OpenGL Shading Language video mixer

Mar 29, 2005 | Categories: Applications | Comments

This demo with source, uses the OpenGL Shading Language to create a video mixer where you can blend two video sources together. It requires an NVIDIA FX 5200+ or ATI Radeon 9500+.

OpenGLEAN 0.2 GLUT work-alike adds support for Win32 and OpenGL auxillary buffers

Mar 25, 2005 | Categories: Developers | Comments

OpenGLEAN is an evolution of GLUT based on OpenGLUT and freeglut. It provides an OpenGL API 3D graphics rendering context attached to windows. (The name is supposed to suggest “lean”, in contrast to “glut”). The new v0.2 adds support for Win32 using C and .Net. It also adds support for OpenGL auxiliary buffers (a possible first for GLUT-like programs)

sdljava adds support for GLU to OpenGL API java bindings

Mar 25, 2005 | Categories: Developers | Comments

sdljava is a java binding to the SDL library with support for access to the audio, keyboard, mouse, joystick, 2D framebuffer and OpenGL API-accelerated 3D hardware.  This latest release adds GLU support to the gljava OpenGL API bindings.

Mar 23, 2005 | Categories: Developers | Comments

The open source Tao Framework is a complete framework to develop OpenGL API-based applications in .NET enviroments, including cutting-edge games, a graphics demo, a data visualization application, or an audio application. It is cross platform using the Mono plaform and supports Cg, DevIL, FreeGLUT, ODE, OpenAL, OpenGL, and SDL APIs.

NOC OpenGL API-based protein structure visualization, model-building and analysis

Mar 23, 2005 | Categories: Applications | Comments

NOC is a free program for protein structure model-building,  visualization, validation and analysis. It supports hardware 3D-stereo views using OpenGL API quad-buffer, OpenGL API-based vivid rendering, line-smoothing, fogging, lighting, and 3D text-generation for labeling.

Optimizing OpenGL data throughput on Mac OS X

Mar 22, 2005 | Categories: Developers | Comments

This article begins with a discussion of general optimization concepts, such as usign GLfloats, minimizing state changes, using threads etc. Feature topics include drawing with vertex data, handling static vertex data, handling dynamic vertex data and handling mixed data. Pseudo code is offered. The general concepts are applicable to all OpenGL API coders: Don’t do any work you don’t have to do; take maximum advantage of the available CPU and GPU hardware; and let your hardware resources work as independently as possible

High dynamic range rendering in OpenGL using the OpenGL Shading Language

Mar 22, 2005 | Categories: Developers | Comments

This new demo (page 12 of the OpenGL demo series) features high dynamic range rendering using the OpenGL API and the OpenGL Shading Language. It includes full source to both the application and shaders as well as Visual Studio .NET project files.

Really Slick Screensavers features many OpenGL API-based screen savers for Windows with ports to Mac OS X and Linux.  The new Hyperspace screensaver is a real number cruncher with great effects. Most of the other screensavers have also been updated with performance optimizations. All screensavers are available as source code as well.

OpenGL Shading Language “GLSL Tutorial” adds a Texturing section with a glow in the dark effect

Mar 21, 2005 | Categories: Developers | Comments

The GLSL tutorial, a growing body of OpenGL Shading Language turorials, has been updated to include texturing shaders. It covers the basics from simple texturing, multitexturing, and concludes with a glow in the dark effect where texturing is performed conditionally based on lighting.
