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

Apr 29, 2005

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

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

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.

pdnmesh v0.2.2 OpenGL API-based automatic mesh generator and solver for Finite Element problems hand

Apr 27, 2005

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.

Soft shadows using the Nvidia OpenGL fragment program 2

Apr 25, 2005

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%.
