Amanith vector graphics library v0.3 adds SVG 1.2-compliant enhanced alpha compositing layer using t

Jan 30, 2006

The Amanith Framework is a cross-platform (Linux, Win32, MacOS X, FreeBSD and IRIX) open source C++ library for vector graphics. The new v0.3 adds a full SVG 1.2-compliant enhanced alpha compositing layer, supporting all 24 compositing operations (base and extended Porter-Duff) using the OpenGL API. This makes Amanith the first opensource and crossplatform library that supports all of them in hardware (15 of 24 are available also without fragment programs). In addition a full geometry caching system has been introduced to speed up all drawing tasks.

OpenGL Shading Language, 2nd Edition

Jan 25, 2006

OpenGL Shading Language, Second Edition, extensively updated for OpenGL 2.0, is the experienced application programmer’s guide to writing shaders. Part reference, part tutorial, this book thoroughly explains the shift from fixed-functionality graphics hardware to the new era of programmable graphics hardware and the additions to the OpenGL API that support this programmability. With OpenGL and shaders written in the OpenGL Shading Language, applications can perform better, achieving stunning graphics effects by using the capabilities of both the visual processing unit and the central processing unit. New chapters that discuss lighting, shadows, and surface characteristics; and an under-the-hood look at the implementation of RealWorldz, the most ambitious GLSL application to date. The second edition also features 18 extensive new examples of shaders and their underlying algorithms
