From the open call for authors:
After the tremendous success of the first seven entries to the ShaderX book series, and the upcoming success of the GPU Pro book, we are looking for authors for GPU Pro 2. The upcoming book will cover advanced rendering techniques that run on the DirectX and/or OpenGL run-time or any other run-time with any language available. It will include topics on: Geometry Manipulation; Rendering Techniques; Handheld Devices Programming; Effects in Image Space; Shadows; 3D Engine Design; Graphics Related Tools; Environmental Effects and a dedicated section on mathematics used in graphics programming.
Proposals are due by May 17th, 2010. Please send them to wolf at shaderx.com. An example proposal, writing guidelines and a FAQ can be downloaded from http://gpupro2.blogspot.com/.
