OpenCTM 3D viewer adds conversion functionality
Category: Applications • Comments • Permalink
Dec 14, 2009
The latest version of the OpenCTM 3D mesh viewer (part of the OpenCTM v1.0.2 SDK) has support for loading, viewing and saving several different file formats (OpenCTM, COLLADA, STL, PLY, OBJ and 3DS), making it a convenient companion tool for 3D graphics developers and artists. The viewer uses OpenGL for its 3D view and GUI, and works under Windows, Mac OS X, Linux, etc. OpenCTM is a file format, software library and a tool set for compression of triangle meshes. It fits well with the current OpenGL rendering pipeline, with support for custom shader attributes among other things.
Khronos Group WebGL WG releases draft specification of WebGL

The Khronos WebGL WG released a draft specification of WebGL, a royalty-free, cross-platform API that brings OpenGL ES 2.0 to the web as a 3D drawing context within the HTML5 Canvas element, exposed as low-level Document Object Model interfaces. It uses the OpenGL shading language, GLSL ES, and can be cleanly combined with other web content that is layered on top or underneath the 3D content. It is ideally suited for dynamic 3D web applications in the JavaScript programming language, and will be fully integrated in leading web browsers.
ARB Working Group approves updates to the OpenGL 3.2 and OpenGL Shading Language 1.50

The ARB Working Group has approved updates to the OpenGL 3.2 (release 20091207) and OpenGL Shading Language 1.50 (release 11) Specifications which correct many minor issues that have been identified since GL 3.2 and GLSL 1.50 were initially released. Corresponding updates to GLSL 1.40 (release 8) and GLSL 1.30 (release 10) Specifications have also been released, and will be followed shortly by corresponding updates to OpenGL 3.1 and 3.0. All Specifications are available in the OpenGL Registry .

Nokia has released Version 4.6 of its Qt cross-platform application and UI framework. Key performance improvements include an optimized, re-written Qt GraphicsView rendering algorithm and a new OpenGL paint engine. Qt 4.6 includes support for the Symbian platform for the first time, and adds Windows 7, Apple Mac OS 10.6 (Snow Leopard), and the upcoming Maemo 6 to the list of Qt-supported platforms.
TNGViewer 1.1.0.470 adds support for multiple OpenGL windows

Immaginaria Ltd is proud to announce a major update to TNGViewer, featuring support for multiple independent windows, each with its own state, via the File->New option. This enables viewing multiple models and scenes in a natural way. OpenGL resources (such vertex and fragment shaders, textures, and so on) are shared among windows as much as possible: e.g. if you open multiple models that refer to the same textures, a single copy of any given texture will be used. This release also adds support for a couple of useful preference settings, namely the initial antialias level and frame rate for new windows.
HPMC OpenGL library that extractes iso-surfaces of volumetric data directly on the GPU

HPMC is an implementation of the method described in C. Dyken, G. Ziegler, C. Theobalt, H.-P. Seidel, High-speed Marching Cubes using Histogram Pyramids, Computer Graphics Forum 27 (8), 2008. The library analyzes a lattice of scalar values describing a scalar field that is either stored in a Texture3D or can be accessed through an application-provided snippet of shader code. The output is a sequence of vertex positions and normals that form a triangulation of the iso-surface. HPMC provides traversal code to be included in an application vertex shader, which allows direct extraction in the vertex shader. Using the OpenGL transform feedback mechanism, the triangulation can be stored directly into a buffer object.
