Segmentation fault (core dumped) with Irrlicht Visualization
Closed this issue · 2 comments
I keep getting this error when uncommenting the Irrlicht visualization code in scenenet_room_generator.cpp. I want to be able to visualize the scene without rendering the images in renderer so this seemed like how I would do it. After a long time debugging, I still have yet to find a solution that will help me work around this error
Any help would be appreciated!
Unfortunately I have been unable to reproduce this, so it's a bit tricky to track down. Just to be clear we are doing the same thing, to show the visualiser in scenenet_room_generator.cpp I uncommented lines 603-615 and 732-754, and commented out lines 726-728. When I did this it visualised the physics scene without a problem. I previously used irrlicht 1.8.2 without problem but on my current system I am using a slightly updated 1.8.3 version of irrlicht - can you try that version to see if it helps?
Also, have you tried compiling with the -g flag (to the CMakeLists.txt e.g. COMPILE_FLAGS "${CHRONO_CXX_FLAGS} -g") so that you can pinpoint the error with gdb (here's an example tutorial showing how to pinpoint segfaults with gdb).
Alright so using irrlicht 1.8.3 seems to have fixed the problem, but now I just see the layout but none of the objects in it. Is this what the visualizer is supposed to do?
Update: I used a couple of couts in the second while loop for visualization and it just keeps looping through the loop and doesn't actually draw anything. Below is a picture of what the visualizer shows me.
Also how would one go about adding their own objects to the program. I looked through the textfiles/ directory and looked through all the files. From what I understand, I just need to edit train_split_filtered_model_info_and_texture.txt and wnid_sample_probabilities.txt. However, since you did this for tens of thousands of objects, do you have a script to automate it already?
Thanks!
