EXT_framebuffer_object (FBO) extension now available

Jan 18, 2005

The EXT_framebuffer_object (FBO) extension is the long awaited render-to-texture extension developed by the ARB’s “superbuffers” working group. It defines a simple interface for drawing to rendering destinations other than the buffers provided to the GL by the window-system and enables a form of “offscreen” rendering and “render to texture”. This specification is the evolution of an effort that has its roots in draft proposals such as uberbuffers and render_target.

RenderMonkey 1.5 X3D Exporter with OpenGL Shading Language support

Jan 17, 2005

RmX3DPlugIn is an X3D importer/exporter for ATI RenderMonkey 1.5 shader authoring tool. It aims to be conformant with the X3D Ammendment 1 draft specification (X3D is the XML-savvy successor to VRML). Capabilities include the export of X3D as both worlds and prototypes for maximum reuse of shader representations, and script representations of RenderMonkey’s built-in variables. It fully supports shaders written in both the OpenGL Shading Lanugage and HLSL.

JetStreamFX uses the OpenGL API to render particle FX in Lightwave 3D

Jan 17, 2005

JetStreamFX is a rendering system for particles that operates in LightWave 3D Ver. 6.5-8.0. Visual effects like, volumetric smoke, clouds, flames, dust, etc. are created in high speed by using the OpenGL API for rendering. Special FX, such as shockwaves, can be generated by replacing the particles with lens flare or an object.

Advanced Graphics Programming Using OpenGL

Jan 14, 2005

feature graphic

The new book (shipping Feb 16, 2005), Advanced Graphics Programming Using OpenGL, brings the graphics programmer beyond the basics and introduces them to advanced knowledge that is hard to obtain outside of an intensive CG work environment. The book is about graphics techniques - those that dont require esoteric hardware or custom graphics libraries - that are written in a comprehensible style and do useful things. It covers graphics that are not covered well in your old graphics textbook. But it also goes further, teaching you how to apply those techniques in real world applications, filling real world needs. Authors are from Nvidia and Microsoft.
