History of hardware tessellation by Daniel Rákos

Categories: Developers |

Sep 30, 2010

With the introduction of Shader Model 5.0 hardware and the API support provided by OpenGL 4.0 made GPU based geometry tessellation a first class citizen in the latest graphics applications. While the official support from all the commodity graphics card vendors and the relevant APIs are quite recent news, little to no people know that hardware tessellation has a long history in the world of consumer graphics cards. In this article I would like to present a brief introduction to tessellation and discuss about its evolution that resulted in what we can see in the latest technology demos and game titles.

TNGViewer 1.5.1.670 significantly improves cache performance

Categories: Applications |

Sep 27, 2010

Immaginaria Ltd. is happy to announce an update to TNGViewer, featuring a substantial improvement in scene cache performance. Textures images can now be stored uncompressed in the cache, which provides shorter import times at the cost of a little disk space. Furthermore, rendering resources footprint has been reduced in both the OpenGL and DirectX renderers. Finally, the Open Asset Import Library was upgraded to version 1.1 (r815), improving file format support.

Efficient Gaussian blur with linear sampling by Daniel Rákos

Categories: Developers |

Sep 08, 2010

Gaussian blur is an image space effect that is used to create a softly blurred version of the original image. This image then can be used by more sophisticated algorithms to produce effects like bloom, depth-of-field, heat haze or fuzzy glass. In this article I will present how to take advantage of the various properties of the Gaussian filter to create an efficient implementation as well as a technique that can greatly improve the performance of a naive Gaussian blur filter implementation by taking advantage of bilinear texture filtering to reduce the number of necessary texture lookups. While the article focuses on the Gaussian blur filter, most of the principles presented are valid for most convolution filters used in real-time graphics.

Extending our free tutorial on Stereoscopic rendering in OpenGL, Binocularity.org has added a C++ version of our software alongside the existing Python download. Detailed instructions for compiling and running the software on a Windows PC are included. This new download supports anaglyph and shutter glasses modes for viewing the output on all types of 3D monitors and displays. The parallel and toed-in stereoscopic camera methods can now be compared directly as the C++ program supports hot-switching between them.
