From 003663649a191fc5bc011d6e5424496576b5e793 Mon Sep 17 00:00:00 2001 From: Willem Jan Palenstijn Date: Thu, 8 Oct 2015 11:24:49 +0200 Subject: Improve option passing through CudaProjector2D Not all constructors were reading options from the projector. Also allow passing GPUIndex via CudaProjector2D. Also refactor CudaReconstructionAlgorithm::initialize/check to avoid code duplication with ReconstructionAlgorithm. --- include/astra/CudaSirtAlgorithm.h | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) (limited to 'include/astra/CudaSirtAlgorithm.h') diff --git a/include/astra/CudaSirtAlgorithm.h b/include/astra/CudaSirtAlgorithm.h index 607889a..751d612 100644 --- a/include/astra/CudaSirtAlgorithm.h +++ b/include/astra/CudaSirtAlgorithm.h @@ -97,18 +97,13 @@ public: /** Initialize class. * - * @param _pProjector Projector Object.
