Crystal Space and Crystal Entity game layer v1.0RC1 with support for OpenGL API-based shaders

Nov 29, 2006 | Categories: Developers | Comments

Crystal Space is a powerful Open Source and portable 3D engine which supports the OpenGL API for rendering. Crystal Entity Layer is an Open Source 3D game framework which sits on top of Crystal Space and adds the notion of ‘game entities’ or ‘game objects’. The first candidate release for Crystal Space and Crystal Entity Layer 1.0 (1.0rc1) is available. It support CG and ARB shaders (both fragment and vertex shaders), support for lightmaps or hardware based lighting and shadows, physics using ODE, 3D sound, skeletal animation, a terrain engine and more.

Unity v1.6 OpenGL API-based 3D game environment enhances integration with web browsers via DHTML

Nov 29, 2006 | Categories: Developers | Comments

Unity is an OpenGL API -based 3D game development tool with support for shaders, advanced lighting, physics, networking, scripting and more.  Developers can deploy games on Mac OS X and Windows, and even create Dashboard widgets. The new v1.6 adds collaboration tools, support for Windows Vista, pitch and doppler audio FX, drop-in support for .NET libraries, and texture painting. The Unity Web Player browser plugin can now fully interact with DHTML web pages that it’s embedded in. The Unity plug-in supports IE, Safari, Firefox, Mozilla, Netscape and Camino on Mac OS X and Windows.

OpenGL FrameBuffer Object 101

Nov 27, 2006 | Categories: Developers | Comments

The Frame Buffer Object (FBO) extension was introduced to make Render to Texture objects much more efficient and much easier to perform when compared with the copying or pbuffer alternatives. This article gives a quick over view of how to use this extension and some things to keep in mind when using it so you can add faster Render to Texture functionality to your OpenGL API-based programs.

Red engine real-time ray-tracer using the OpenGL API in a scalable GPU based 3D engine

Nov 20, 2006 | Categories: Developers | Comments

Fully based on top of the OpenGL API, the Redsdk is a scalable GPU engine that includes real-time lighting and shadowing,  real-time raytracing, a scene graph with customizable transformation pipeline, and offline high quality ray-tracing. Leveraging most of ARB shader standards, programs written for real-time application rendering can be used for the production of true ray-traced effects.

The second edition of OpenGL Pipeline, the quarterly newsletter covering all things the OpenGL standards body has “in the pipeline”, covers many important issues: from what to expect in the new SDK,  to information about OpenGL “Longs Peak” and OpenGL “Mt. Evans”, to technical optimization.

Topics in this issue include:

  • Transitions (two new OpenGL releases in 2007)
  • One SDK to Rule Them All
  • The New Object Model
  • Platform TSG Update
  • “Clean” your OpenGL usage using gDEBugger

GLee OpenGL Extension library adds support for OpenGL 2.1 and GeForce 8 OpenGL extensions

Nov 17, 2006 | Categories: Developers | Comments

GLee (GL Easy Extension library) is a free cross-platform extension loading library for the OpenGLAPI . It provides seamless support for almost all OpenGL extensions and core functions up to OpenGL 2.0, automatically linking extension and core functions as they are used.  The new v5.21 adds OpenGL 2.1 core support and NVIDIA GeForce 8 series extensions. 362 extensions are now supported.

Tutorial on using NVIDIA geometry shaders with the OpenGL Shading Language

Nov 16, 2006 | Categories: Developers | Comments

This tutorial explains how to use NVIDIA’s geometry shaders extensions to the OpenGL Shading Language (available for the GeForce 8 Series). A geometry shader begins with a single primitive (point, line, triangle). It can read the attributes of any of the vertices in the primitive and use them to generate new primitives. A geometry shader has a fixed output primitive type (point, line strip, or triangle strip) and emits vertices to define a new primitive. A geometry shader can emit multiple disconnected primitives. The primitives emitted by the geometry shader are clipped and then processed like an equivalent OpenGL primitive specified by the application. A Windows demo is included.

Starry Starry Night OpenGL API-based screensaver

YZGalaxy is an OpenGL API-based screen saver that simulates all types of galaxies. The author was inspired by PBS show ‘Monster of the Milky Way’ and Vincent van Gogh’s painting ‘The Starry Night’.

Framebuffer Object class v1.5 supports attaching mulitple tetures with a single entry point

Nov 13, 2006 | Categories: Developers | Comments

The EXT_framebuffer_object allows you to take a texture object and “attach” it to a framebuffer. This provides a lightweight mechanism to “divert” the output of a rendering / computation pass away from the framebuffer for immediate display, but into a texture which can be used again as input for subsequent passes. Aaron Lefohn created a framebuffer object class and example application. The new v1.5 updates enumerations in error checking to match current FBO specification, better supports attaching multiple textures with a single entry point and adds a FBO Manager for managing a pool of FBOs based on width, height, and format.

Ultimate Stunts v0.6.3 adds OpenGL API-based graphic enhancements

Nov 13, 2006 | Categories: Applications | Comments
