Some of the new features include: Frustum Culling with OpenGL frustum Plane extraction; space partitioning using Octree; ability to save all supported 3D Formats in a 3DXML ASCII V4; built in 3DWidget; built in Plane sectioning with easy and powerfull manipulation tools. Supported file formats include COLLADA, 3DXML ASCII V3 and V4, OBJ, 3DS, STL (ASCII and binary), and OFF and COFF.   Read More

Assimp 1.1 released with improved COLLADA support

• Tags:

Open Asset Import Library (Assimp) release 1.1 is out. It features many bugfixes, improvements and new file formats as well (i.e. Milkshape 3D) and now supports more than 25 3D file formats out of the box, including COLLADA, Obj, 3DS and LightWave formats. COLLADA support has been vastly improved and most DCC applications play well with Assimp's COLLADA Loader. Assimp is an Open Source library (BSD-style license) written in C++.   Read More

SimLab Composer 2.0 adds support for COLLADA

• Tags:

SimLab Composer allows the user to create 3D scenes from a wide range of CAD and 3D Design formats, including COLLADA, SketchUp, Rhino, Solidworks, STEP, IGES, FBX, 3DS, OBJ, and STL. 3D Scenes built by SimLab Composer can also be exported to other 3D applications using many standard 3D formats including COLLADA, obj, STL, FBX, OSG and U3D. SimLab Composer is a 3D sharing and rendering application.   Read More

Difference between CUDA and OpenCL

• Tags:

Ever wonder what the difference between CUDA and OpenCL is? Streamcomputing has done a good job in clarifying the differences between CUDA and OpenCL. The article covers speed, language, heterogenous vs. homogenous and some of the terminology.   Read More

Maximizing OpenGL(R) ES 2.0 on GPUs for Embedded Applications Webinar

• Tags:

ARM is sponsoring a webinar on April 22nd at 1PM EST. Ed Plowman, Technical Marketing Manager, Media Processing Division of ARM will present this webinar which will provide a background to the OpenGL ES 2.0 standard. Benefits of having OpenGL ES 2.0 running on top of ARM Mali™ Graphics processors and the tools and resources available enabling developers and design engineers to start developing for Mali GPUs will be covered. This is webinar is useful for developers and people investigating GPUs and what they can enable in embedded applications.    Read More

NVIDIA releases OpenGL 4.0 drivers

• Tags:

NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:

  • ARB_texture_compression_bptc – provides new texture compression formats for both fixed-point and high dynamic range floating-point texels.
  • EXT_shader_image_load_store - allows GLSL- and assembly-based shaders to load from, store to, and perform atomic read-modify-write operations to texture images.
  • EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
  • NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
  • NV_gpu_program5 - provides assembly programmability support for new hardware features provided by NVIDIA’s OpenGL 4.0-capable hardware in vertex, fragment, and geometry programs.
  • NV_tesssellation_program5 - provides assembly programmability support for tessellation control and evaluation programs.
  • NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5 and GLSL 4.00. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector integer data types, and more. Additionally, it allows patches (as used in tessellation) to be passed on to the geometry shader, used as input to transform feedback, and rasterized as a set of control points.
  • NV_shader_buffer_store – extends the bindless graphics capabilities of the NV_shader_buffer_load extension. This extension provides the ability to store to buffer object memory, and to perform atomic read-modify-write operations, using either GLSL- or assembly-based shaders.

The official feedback thread is available in the OpenGL Discussion Forums. The drivers and extension documentation can be downloaded from
