Hello, I am trying to make the EGL build of ParaView work, but I am encountering some issues.
First, here is the configure line I used to build ParaView: cmake .. \ -DBUILD_TESTING=OFF -DPARAVIEW_ENABLE_CATALYST=ON -DPARAVIEW_ENABLE_PYTHON=ON \ -DPARAVIEW_INSTALL_DEVELOPMENT_FILES=ON -DPARAVIEW_USE_MPI=ON \ -DVTK_RENDERING_BACKEND=OpenGL2 -DVTK_USE_OFFSCREEN_EGL=ON \ -DVTK_USE_X=OFF -DPARAVIEW_BUILD_QT_GUI=OFF \ -DEGL_gldispatch_LIBRARY=<path_to_libGLdispatch.so.0> \ -DEGL_INCLUDE_DIR=<path_to_EGL_includes> \ -DCMAKE_INSTALL_PREFIX=<install_prefix> Everything then builds and installs correctly. But when I start a pvserver (with no X server launched) on the server where the data is stored and with a graphic card. I end up having the following issue in a ParaView pop-up: " OpenGL drivers on the server side don't support required OpenGL features for basic rendering. Remote rendering will be disabled. OpenGL Vendor: NVIDIA Corporation OpenGL Version: 4.5.0 NVIDIA 358.16 OpenGL Renderer: Tesla K80/PCIe/SSE2 " And then I tried to use volume rendering, but I end up with this error: " Some of the representations in this view require remote rendering which, however, is not available. Rendering may not work as expected. " And VR does not work. I managed to replicate this issue, with both a Nvidia Tesla K80 and GTX 470 with the 358.16 driver from NVidia on a Ubuntu 14.04. However, when I add the "--disable-xdisplay-test" option to the pvserver. I don't get the error regarding to OpenGL drivers and I am able to do remote rendering on the server side. I also tried adding the "–egl-device-index=0" instead of "--disable-xdisplay-test", but I am getting the OpenGL error. Is there something I missed in my ParaView build ? I guess I should be able to run the pvserver without the "--disable-xdisplay-test" option, isn't it ? Another last question, is the EGL internal rendering resolution available for modification or will it fit the current view of ParaView ? (e.g. for doing screenshots) Thanks in advance for the answers, Best regards, Alexandre Ancel -- Alexandre Ancel Docteur, Ingénieur de recherche / Phd, Research Engineer Cemosis <http://www.cemosis.fr> - [email protected] Tel: +33 (0)3 68 8*5 02 06* IRMA - 7, rue René Descartes 67 000 Strasbourg, France
