Realistic natural effect rendering of water using the OpenGL API and Cg

Sep 10, 2004 | Categories: Developers | Comments

This article on rendering water using a planar reflection technique is the first in a series on realistic natural phenomena rendering for the intermediate to experienced graphics programmer. Source snippets and pseudo code are provided for many important functions, and the amount of math is kept to the relevant minimum. Concrete examples are written according to the OpenGL API.  Many of the effects presented are very shader heavy, mostly targeting current generation 3D chipsets. All shader code is written in the Cg language, but porting it to to the OpenGL Shading Language should be straightforward.

The 2nd Khronos Developer University Lecture Series is being held Sept 17 2004 in Helsinki.  This event is also the start of the OpenGL ES 1.1 Coding Challenge. The focus of the Lecture Series Event is on OpenGL ES. Sessions include:

  • OpenGL ES for everybody: A walk through the API
  • The challenge of migration going from desktop to handheld
  • Coping with fixed point: Staying grounded in a float free world
  • Harnessing the horsepower of OpenGL ES hardware acceleration
  • 10 habits of highly efficient developers: Tips & tricks with OpenGL ES

German language OpenGL API Wiki

Sep 08, 2004 | Categories: Developers | Comments

The Delphi-OpenGL-Community started a German language Wiki that includes an OpenGL API function overview (like the GL Man pages, but also including GLU, WGL and GLX), and other categories about the OpenGL API and 3D-Realtime techniques. They currently have about 160 articles but still seek people that are interested in helping out (you don’t need to write new articles, you can also help to improve already written articles).

VisIt OpenGL API-based parallelized visualization tool for 2D & 3D meshes

Sep 02, 2004 | Categories: Applications | Comments

VisIt is an OpenGL API-based distributed, parallel visualization and graphical analysis tool for data defined on two- and three-dimensional meshes. The new public release supports the ability to visualize vector fields using streamlines, generalized query capability, stereo rendering, and beta keyframing.

Molecule Viewer gives fast views of molecular structures using OpenGL API-rendering

Sep 02, 2004 | Categories: Applications | Comments

Molecule Viewer allows users to view molecular structures stored in a wide variety of file formats including Brookhaven
PDB, Alchemy, MDL, Gaussian, MOPAC, etc by simply right-clicking on the file in Windows Explorer and selecting the “Preview” command. It uses the OpenGL API for rendering and supports viewing structures using traditional ball and stick, viewing proteins as ribbons, cartoons, barrels and tubes, viewing of molecular orbitals and iso-density surfaces.

Keyhole 2 enterprise suite uses grid networks for geospatial analysis using the OpenGL API for visua

Sep 02, 2004 | Categories: Applications | Comments

Keyhole uses the OpenGL API to create 3D representation of the entire earth comprised of terabytes of imagery and other data. You can log in from a standard PC and fluidly fly to any point on the earths surface viewing sub-meter imagery, elevation and map data. Then overlay GIS files, maps, or operational data. The Keyhole 2 enterprise suite introduces support for grid networks, enabling massive quantities of data to be processed across dozens of CPUҒs

jME v0.7 Java scene graph API adds OpenGL API pixel shader support

Sep 02, 2004 | Categories: Developers | Comments

jME (jMonkey Engine) is a high performance scene graph API written in Java. It currently supports OpenGL API rendering using the Lightweight Java Game Library (LWJGL). The new v0.7 release improves documentation, model loading, adds a render que, and support pixel shaders.

Cheetah3D V1.8 adds adaptive anti-aliasing and fog support with OpenGL API previews

Sep 02, 2004 | Categories: Applications | Comments

Cheetah3D is an OpenGL API-based lean, fast and elegant 3D modeler and renderer for Mac OS X with tools for polygon and spline editing, lathe, sweep, extrude, boolean and subdivision surfaces. Models are arranged in a scene graph. This v1.8 release adds adaptive antialiasing speed up rendering in scenes with high antialiasing, and fog support by attaching the new fog tag to your camera object.

Mediocre Media Player v0.1 for Win32 using OpenGL Shading Language

Aug 30, 2004 | Categories: Applications | Comments

The Mediocre Media Player is a simple media player for Win32, designed to be small, fast and flexible. It uses OpenGL for rendering and developers may be interested in the source code as it implements video textures using the OpenGL Shading Language that are actually faster than DirectShow overlay rendering on ATI cards.
