Thanks in advanced. Under /usr/include/NVX/nvx.h, nvxHoughCirclesNode should use NVX_TYPE_POINT3F as output para, but why nvxHoughLinesNode? NVX_TYPE_POINT3F is used to describe arc, right? Would Nvidia provide a method to draw hough line? (Note: not nvxHoughSegmentsNode)
Currently we don’t have plan to upgrade VisioWorks to new version. If current implementation is not able to fulfill your usecase, you may consider to implement the function through CUDA.
