breve OpenGL API-based multi-agent and artificial life simulation environment enhances 3D performanc
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.
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 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.
JUCE is an C++ class library for developing cross-platform applications with a focus on creating highly-specialised user interfaces and for handling graphics and sound. Its features include fully lightweight components with transparency and effects, classes for strings, containers, XML, streams, file handling, messaging, and event queues, vector graphics, a custom font engine, image manipulation, OpenGL API support, low-latency audio I/O using CoreAudio, DSound and ASIO, audio buffers and nodes, MIDI file and event manipulation, Internet streams, undo/redo support, and more. V1.9 added support for the OpenG API. V1.10 adds support for Linux.
pdnmesh v0.2.2 OpenGL API-based automatic mesh generator and solver for Finite Element problems hand
pdnMesh is an automatic mesh generator and solver for Finite Element problems. Common applications occur in electromagnetics, heat flow and fluid dynamics. It will also do post-processing to generate contour plots and Postscript printouts. The quality and the coarseness of the mesh can be controlled by giving input parameters.It requires OpenGL and GTK (linux) or MFC (Win32). The new v0.2.2 improve Windows support and solves very large eigenvalue problems.
The OpenGL API-based Torque 2D and Torque Game engines will take advantage of 64-bit support and Xcode 2.0 optimizations under Mac OS Tiger. These enhancements deliver into both professional and consumers hands the ability to create native Mac OS X games with the highest quality tools available for less than a 1,000th the price of comparable technologies on the market.
Extruder is a program to create 3D objects using extrusion technique.
It uses the OpenGL API to render the objects in real time with textures from photos or scans. The site features an example of Rome’s Constantine arc reproduced from real photos.
This demo uses the Nvidia OpenGL API extension NV_fragment_program2 aka Pixel Shader 3.0 to create a soft shadows where the penumbra is generated by jittering the sampling position up to 64 times and averaging the results. The advantage of Pixel Shader 3.0 is that you don’t have to over sample unless on a shadow edge. If you detect that you’re on a lit or completely shadowed area, you can skip the 28 x 2* of 32x2* texture fetch necessary to blur the penumbra, yielding performance gains up to 50%.
Attempt to keep your eyeballs in their sockets as you watch this Mac OS X screen saver display the Matrix code swirl on your desktop in mind bending OpenGL API 3D! It can also be set to display the traditional 2D code, as well as heaps of other options.
AV_TEC is a virtual reality driving simulator for determining road and traffic optimizations. It uses the OpenGL API for rendering and lets you adjust for weather conditions, lighting and road terrain. Website in spanish.
DAZ|Studio is a free OpenGL API-based application to create digital scenes using imported 3D models and includes pre-configured 3D scenes, complete with a poseable character, accessories and environments. Scenes can easily be manipulated including character poses, shape morphs, model textures, and lighting. The new v.9.20.1 renders multiple pass OpenGL renders to an alpha channel and fixes several lighting and camera bugs.
gDEBugger is an OpenGL API debugger and profiler that traces application activity on top of the OpenGL API letting programmers see what is happening within the graphic system implementation. The new v1.4 supports OpenGL 2.0 and many additional extensions. The latest features include forcing the debugged application to use a stub fragment shader and forcing it to render using no lights. These features enable the pinpointing of application graphic performance bottlenecks caused by either fragment shaders or light-related calculations. The texture viewer also now displays images and properties of multi-textures.
Gizmo3D is an OpenGL API-based 3D engine which supports fast geometry, real time shadows, particles, recursive structures (trees etc), CLOD, APARS, CAT, scene graph queries, shaders, animation, environment, integrated scene graph physics/triggers and dynamics. The new v1.3.14 increases speed by allowing the scene graph to optimize state changes in runtime and use results from a previous rendered frame (and scene) and use them in the current frame. It also shows an external debug view.
Boris FX offers broadcast-quality fx and compositing features directly inside nonlinear editing systems. Features include: realistic lighting, advanced keying and color correction, unlimited layers, DVE, vectorpaint, support for third-party After Effects filters and OpenGL API hardware accelerated previews. The new FX 8.0 features a new template mode as well as new Motion Tracking, Stabilizing and Corner Pin Tracker filters and performance improvements of up to 20 percent in rendering speeds.
AgentFX is a platform-independent 3D engine with scene graph for advanced real-time 3D graphics. AgentFX is based on Java and uses the OpenGL API. It includes extensive high-level methods for creating, configuring and interacting with real-time simulations. A single method call does the work of hundreds of lines of code, dramatically shortening product-development times. This series of 10 articles covers getting started, lights & shading, vectors & matrices, nodes and the rendering pipeline.
