I'm considering extending one of my applications, Pointor, to read LiDar files (LAS and LAZ). Pointor takes pointlists and turns them into DXF files. But after a few experiments I've found that AutoCAD cannot really handle large collections of points, as native AutoCAD points anyway. 3D viewing is so slow I've had to stop AutoCAD running. So I'm wondering if an application which created DXF files from lidar point data would have any realworld application? Or maybe I should allow the user to input only a fracrion of the points from large files? Or...?
