MeVisLab 2.2 offers extensible GPU Ray Caster

The medical imaging and visualization platform MeVisLab now contains a full featured GPU Ray Caster for Volume Rendering, based on OpenGL and GLSL. The Renderer is fully extensible by the MeVisLab user, using a modular SuperShader approach (see SoShaderFunction module). The Volume Renderer supports: Directional Lights, Point Lights (with attenuation), Tone Shading, Silhouette/Boundary Enhancement, Tag/Mask Volumes, Multiple Data Volumes, Per Object shading, MIP/MIDA, LitSphere shading, Endoscopic rendering, First Hit ISO Surface Rendering and integration of opaque GL geometry. The MeVisLab SDK is a free download for non-commercial use. To get started with the ray caster, have a look at the SoGVRRayCastSettings module.

NeoAxis Game Engine 1.0 is finally released!

NeoAxis Group has finally released NeoAxis Engine 1.0. It took over six years for NeoAxis Engine to grow from a project being developed by a single enthusiast into a most innovative 3D development tool with an international team working on it. NeoAxis Engine is an all-purpose, modern 3D graphics engine for 3D simulations, visualizations and games, which uses OpenGL API for Mac OS X rendering. For further information read the press release.

NinevehGL had been released, 3D engine for iOS

The NinevehGL is now online to download! It’s a FREE 3D engine for iOS working with OpenGL ES 2.0 programmable pipeline. Three Killer Features:

  • Imports 3D files from OBJ and COLLADA formats. NinevehGL doesn’t need plugins or special 3D formats to import your objects.
  • Automatically generates special effects like bump mapping, reflections, specular light, etc.
  • Made with pure Objective-C, the native language for iOS, following all the Cocoa Touch guidelines.

NinevehGL also offers full integration with Xcode and Interface Builder tool.

PixelLight 0.9.7-R1 released

Version 0.9.7-R1 of the free open-source, cross-platform 3D application framework PixelLight has been released. The technology is using OpenGL as well as GLSL within it’s primary renderer. This release adds a script language independent script interface with support for global variables, global functions (C++ calls script and script calls C++), namespaces as well as RTTI objects (properties, attributes, methods, signals, slots). There’s a Lua script backend within the SDK and there are experimental plugins for other script languages available. To show the scripting in action, the application logic of the updated dungeon demo is now written within Lua scripts instead of C++.

Customizing of 3D Paper Models using OpenGL

We have developed a prototype (client-server model) for creating custom 3D paper models using OpenGL. The client uses OpenGL for displaying a 3D object while the user can choose among several options to custom the paper model: surface color, edge color and thickness, and images used as stickers. The server computes a high quality paper model using OpenGL for multisampling, texture filtering and off-screen rendering.

ClanLib SDK 2.2.9 Released

The ClanLib SDK has been updated, with a significant improvement in the speed of handling Layered (transparent) windows. Using rendered graphics obtained by glReadPixels from an offscreen opengl context, the output if transformed to ARGB8 suitable for UpdateLayeredWindow by using SSE2 in it’s own thread. A transparent fullscreen animated opengl GUI overlaying the desktop is now possible.

OpenGL Timer Query Tutorial @ Lighthouse3d

In March, 2010, the Khronos group approved an extension to add timers to OpenGL. The version was 3.2. As of OpenGL 3.3 this functionality has become part of the specification. Profiling is an essential technique to truly understand how to improve the performance of an application. Being able to get time measurements is important both in the development stage as well as during run-time after the application has been released. OpenGL Timer Queries allows us to profile the GPU. i.e. to determine the amount of time it takes to execute a command, or sequence of commands in the GPU. This tutorial shows how to use the timer functionality, and describes a technique similar to double buffering to prevent the application from getting stalled while waiting for the query results.
