Fraqtive uses the OpenGL API to display fractals

May 11, 2005 | Categories: Applications | Comments

Fraqtive is an open source program for drawing Mandelbrot and Julia fractals. It uses a very fast algorithm and generates high quality, smooth images. It is fully interactive, allowing for real-time mouse navigation and dynamic generation of the Julia fractal preview. It also support an OpenGL API-rendered 3D view of the fractals.

7 megapixel seamless Clusterwall for OpenGL API-based applications

May 11, 2005 | Categories: Processors | Comments

The seven megapixel Cyviz Clusterwall uses a six Linux PC cluster, enabling OpenGL API-based applications to run in one seamless high resolution image. The latest release uses 3Dlabs Wildcat Realizm 800 to run any OpenGL API-based application from a single, 7 megapixels desktop.

Flaming and glowing 3D text effect using OpenGL Shading Language

May 10, 2005 | Categories: Developers | Comments

feature graphic

This demo with source displays a string lit on fire and generates a glow effect by using a set of OpenGL Shading Language shaders and ARB extensions. On a configuration equipped with Geforce 6200 and up, this application will use floating point targets to achieve not only glow but also a bloom effect.

Heat haze effect using the OpenGL Shading Language and FBO

May 06, 2005 | Categories: Developers | Comments

This demo with source, simulates a heat haze effect through several render to texture passes and a set of OpenGL Shading Language shaders and ARB programs. It uses FBOs to do the offscreen rendering, however if your current driver doesn’t support them, there is a fall back to using the good old glCopyTexImage2D function.

Non-Power-of-Two Mipmapping

May 05, 2005 | Categories: Developers | Comments

Mipmapping is commonly used to avoid sampling artifacts during texture minification. The construction of mipmaps for textures whose size is a power-of-two is usually implemented with a box filter that computes the average of a 2x2 block of texels (texture pixels). This document describes and gives code for a mipmap construction algorithm for non-power-of-two textures that yields good quality results.

Topicscape OpenGL/Java API-based 3D concept mapping tool seeks beta tester

May 05, 2005 | Categories: Applications | Comments

Topicscape is an OpenGL API-based 3D tool to help people organize and find information held in their computer as well as sort out their approach on new projects. It uses a uses a 3D concept mapping approach (a bit like Mind Maps) and allows users to fly around the landscape that they create. But it can also be used for organizing projects and personal material as well as getting your thoughts straight. It’s primarily written in Java and uses the GL4Java binding to the OpenGL API. The authors are looking for beta testers.

Blink 3D rapid application development environment supports the OpenGL Shading Language

May 04, 2005 | Categories: Applications | Comments

Blink 3D is a Rapid Application Development environment for building and sharing full 3D, immersive, interactive, animated environments that can be viewed on the Web or locally. It supports the OpenGL Shading Language, multitexture blending, LOD support, Octrees and BSP, fog, and physics engine, and a full JavaScript API.

Unigine v0.3 OpenGL API-based engine adds advanced fx

May 04, 2005 | Categories: Developers | Comments

Unigine is an OpenGL API-based engine for games and virtual reality systems. The new v0.3 features a graphics engine (with HDR and soft shadows support), physics engine (with ragdoll, fluid buoyancy, ray car, joints destruction support), easy-to-use C++ API, script interpreter with C-like syntax and virtual 3D GUI. Supported platforms are Windows and Linux.

roGL scriptable COM access to the OpenGL API for 3d imaging and video output

May 02, 2005 | Categories: Applications | Comments

Crystal Space (an Open Source and portable 3D game development framework based on the OpenGL API)is looking for donations.  Crystal Space works well on both Windows and GNU/Linux. Crystal Space also works on MacOS/X and 64-bit platforms but there are still many issues on those platforms because non of the main developers have access to such a machine - hence the need for donations.

BioSchematics v0.4.6 L-System tool using the OpenGL API for display

May 02, 2005 | Categories: Applications | Comments

BioSchematics is a L-System interpreter and drawing tool. L-System grammar is interpreted through a Scheme engine (Guile) and results are drawn in an OpenGL window. The new v0.4.6 improves the installation process.

3D Viewer OpenGL API plotting utility

May 02, 2005 | Categories: Applications | Comments

3D Viewer is a utility for plotting lines, surfaces, parametric surfaces and meshes in 3D. It is based on National Instruments 3D Graph control which uses the OpenGL API and provides rich 3D viewing capability.

breve OpenGL API-based multi-agent and artificial life simulation environment enhances 3D performanc

Apr 29, 2005 | Categories: Applications | Comments

breve is a free, open-source software package which makes it easy to construct and visualize 3D simulations of decentralized systems and artificial life.  Users define the behaviors of agents in a 3D world and observe how they interact.  breve includes an easy-to-use scripting language and a rich OpenGL API-based visualization engine. The new v2.2 adds classes for hardware-optimized 3D matrix manipulation, optimized volumetric displays via patches, faster physical simulation and collision detection, and an enhanced GUI for Win and Linux.

NV_vertex_program3 displacement mapping to simulate water effects

Apr 29, 2005 | Categories: Developers | Comments

This OpenGL API demo with source and binaries uses NV_vertex_program3 option on NVIDIA newest cards to perturb a grid mesh and simulate a water effect. (FYI: NV_vertex_program3 is what the DX folks refer to as Vertex Shaders 3.0).  If this demo fails to detect VS3.0 hardware support, it will still run but will only give the illusion of displacement (a 2D water effect instead of a full 3D).

3Dlabs OpenGL 2.0 drivers for Wildcat Realizm

Apr 27, 2005 | Categories: Processors | Comments

3Dlabs Inc released OpenGL 2.0 for Wildcat Realizm professional graphics accelerators. OpenGL 2.0 integrates the OpenGL Shading Language into its core so that software developers can create advanced shader programs and easily port them to any OpenGL 2.0-enabled platform. The drivers are available as a free download.
3Dlabs also offer a set of OpenGL Shading Language development tools.

  • OpenGL Shading Language shader viewer enables the user to interactively control shader parameters, model geometry, textures, animation and see the results in real time
  • The ShaderGen software program provides developers a way to compare fixed-function renderings to OpenGL 2.0s programmable shader renderings through an easy-to-use interface. Using this tool, developers will realize how easy and flexible OpenGL 2.0 is
  • Through the shader validation tool, a shader author can quickly validate whether vertex or fragment shaders meet the OpenGL Shading Language specification
  • A parser testing application helps a developer determine how accurately a graphics compiler matches the OpenGL Shading Language specification.
