TGS Announces Open InventorOffers the CAD/CAM Market Improved Functionality through Added Extensions (October 26, 2001)
Open Inventor 3.0 has also added several features that will broaden its functionality and strengthen its presence in the CAD/CAM marketplace. Major enhancements in version 3.0 include:
Multi-Threading -- Using multiple threads in an application can increase overall performance by making use of multiple processors, or by making better use of a single processor. This also enables use of multiple graphics pipes. Open Inventor can also be used in immersive VR applications based on tools like CAVELib and MPSDK.
Remote Rendering -- Remote rendering allows an Open Inventor application to both execute and render on a remote server machine. Only the compressed rendered images are sent to the local machine. This allows very large data sets to be centralized and handled on a machine with more memory, processors, and graphics hardware.
Big Image Renderer -- The Big Image Renderer renders to an off-screen buffer for printing or generating textures. It automatically does tiled rendering to avoid the image size limitation of OpenGL.
Optimizations for Very Large Data Sets -- A new texture node automatically manages system memory used to hold texture images, and can automatically convert RGBA textures to indexed textures to reduce by 4x the texture memory required. The "Pass-by-Reference" enhancement allows Open Inventor to directly use data from application memory instead of making a copy of the data.
NURBS (Non-Uniform Rational B-Splines) -- Non-Uniform Rational B-Spline (NURBS) curves and surfaces are powerful methods for representing curves and surfaces in parametric form. Instead of using hundreds of points to define a curve or surface, a few control points and parameters can define a complex shape. Open Inventor provides fast and efficient tessellation of NURBS curves and trimmed surfaces with unlimited order.
Beveled Geometry -- A bevel action can be applied to 3D shapes to chamfer edges and corners in order to smooth the geometry and improve the appearance of the object. The application controls the bevel vertices, edges, crease angle, and radius, allowing the object to pick up specular highlights, providing a more "natural" appearance.
