FP3D_CUDA ========= This is a GPU implementation of a simple forward projection algorithm for 3D data sets. It takes a volume as input, and returns the projection data. Supported geometries: parallel3d, parallel3d_vec, cone, cone_vec. Configuration options --------------------- ================================ ======== ================================== name type description ================================ ======== ================================== cfg.ProjectionDataId required The astra_mex_data2d ID of the projection data. The forward projection is added to this data. cfg.VolumeDataId required The astra_mex_data2d ID of the reconstruction data. cfg.option.DetectorSuperSampling optional Specifies the amount of detector supersampling, i.e., how many rays are cast per detector. cfg.option.GPUindex optional Specifies which GPU to use. Default = 0. ================================ ======== ==================================
