Multiple Eigenspaces for Hardware Accelerated Image Based Rendering
Markus Grabner, Horst Bischof, Christopher Zach, Andrej Ferko · 2003
We present a novel hardware accelerated method for rendering images of a 3D scene. The method uses the recently proposed multiple eigenspace method to obtain an e#cient representation of rotated objects that can be easily implemented on modern graphics cards using their fragment shader capabilities. Due to the restrictions of current graphics hardware (which are discussed in detail), the multiple eigenspaces method (originally proposed for the purpose of object recognition) has to be slightly modified. We use the Stanford Bunny model to evaluate our method. Our experiments demonstrate the excellent performance of hardware-based image reconstruction.
