Abstract
- Fourier Volume Rendering (FVR) is a volume rendering technique with lower computational complexity of O(N<superscript>2</superscript>logN) for an N<superscript>3</superscript> data array. A new FVR algorithm is proposed through expanding Fourier Projection-Slice Theorem into High-Dimension and mapping the pipeline totally on GPU. A windowed-sinc function is used as reconstruction filter to implement higher-order interpolation and reduction of samples is executed on GPU in parallel, which meets the architecture of Heterogeneous multi-core. The rendering is accelerated by a factor of 7 when rendering image΄s resolution is larger than 512×512. [ABSTRACT FROM AUTHOR]
