*sl_viewer* A simple OpenGL-based viewer for streaming lines. ----------------------------------- Example usage: <pre>sl_viewer -i ../data/armadillo40.slb</pre> Reads the streaming lines file and displays it every 5000 lines (after you press 'p') while doing on-the-fly simplification with vertex clustering onto a 1024 x 1024 x 1024 grid. <pre>sl_viewer -i ../data/armadillo40.slb -every 50</pre> Same as above but displays it every 50 lines. <pre>sl_viewer -i ../data/armadillo40.slb -grid 6 -win 640 480</pre> Same as above, but with a smaller display window, and more agressive on-the-fly simplification of the lines, with vertex clustering on a 63 x 64 x 64 grid. <pre>sl_viewer -i ../data/armadillo40.slb -ct ../data/armadillo_ct1.slb</pre> Same as above, but also displaying the contour tree that we computed with another streaming technique. <pre>sl_viewer -i ../data/armadillo40.slb -i ../data/lidar_band10.slb -i ../data/PIE_0015.slb</pre> This allows to display several inputs (usually for comparison). To change files simply press 'x' and hit play 'p' again. |*Interactive controls:*|| |_p_ | play/stop| |_o_ | stop| |_space_| switch between rotate/translate/zoom| |_-/=_ | render vertices smaller/bigger| |__/+_ | render lines thinner/wider| |_[/]_ | exaggerate/mellow elevation differences| |_c_ | change color mode| |_b_ | hide/show bounding box| |_s/S_ | step forward/backward| |_t/T_ | tiny step forward/backward| |_r_ | out-of-core full resolution rendering| |_k_ | print kamera parameters to stderr| |_x_ | exchange filenamed (if multiple '-i' inputs)| |_ESC_ | quit| Also try: <pre> sl_viewer -i ../data/armadillo40.slb -ct ../data/armadillo_ct1.slb slclean -i ../data/armadillo40.slb -oslb | sl_viewer.exe -islb slclean -i ../data/armadillo40.slb -length 3 -oslb | sl_viewer.exe -islb slclean -i ../data/lidar_band10.slb -length 2 -oslb | sl_viewer.exe -islb slclean -i ../data/lidar_band10.slb -length 10 -oslb | sl_viewer.exe -islb slclean -i ../data/lidar_band10.slb -length 10 -oslb | slsimp -islb -area 1 -oslb | sl_viewer.exe -islb </pre> For more info: <pre>sl_viewer -h</pre> Usage: <pre> sl_viewer -i lines.sla sl_viewer -i lines1.slb -i lines2.slb sl_viewer -isla < lines.sla sl_viewer -win 640 480 sl_viewer -grid 9 -every 1000 -isla < lines.sla </pre> --------------- if you find bugs let me (isenburg@cs.unc.edu) know.
