Dynamic Shader Generation for GPU-Based Multi-Volume Ray Casting
F. Rossler, Ralf P. Botchen, Thomas Ertl · IEEE Computer Graphics and Applications · 2008
Real-time performance for rendering multiple intersecting volumetric objects requires the speed and flexibility of modern GPUs. This requirement has restricted programming of the necessary shaders to GPU experts only. A visualization system that dynamically generates GPU shaders for multi-volume ray casting from a user-definable abstract render graph overcomes this limitation.
