Raytracer crash with a blocker #3
Comments
Indeed, and a hard one (most likely related to multithread based on the logs). searching... |
Thanks for the feedback! When I move the source or listener slowly, the raytracer crashes much less frequently. I guess if the previous multi-threaded raytracing has not completed, new movement happens and triggers a new round of rays. This might have led to the crashing. Besides the geometry built-in to blender, can I import custom shapes? I made a mesh with OpenSCAD and it seems the raytracer is not behaving correctly. Is there any requirement for the input mesh? mesh quality? topology limit? |
@PyrApple: Yet, in the case of the a door and a hallway, the engine still fails. It either computes a wrong acoustic decay or crashes again like in the triangle mesh cases. I was wondering if you have some already-verified complex scene that I can play with? Something more complex than the square room? Thank you very much. |
Quad vs Tri mesh, you're definitely right there. No official complex model that I can share for the moment, yet would be pleased to handle one of yours that highlights a bug in acoustic decay estimation. Would you mind opening a new thread on that and keep this one for the blocker issue? |
@PyrApple Okay! I will upload my slightly more complex model in a new thread. Since you have worked on this acoustic simulator for a while, are you aware of other similar project or software that has similar functionalities? Thanks a lot! |
Non-exhaustive listing of auralization / spatialization software: EVERTims page on my personal website. |
Hi, when I try to do the auralization in a scene like this, the raytracer keeps crashing. The only new element in this scene is the center blocker. I tried to increase the reflection order, it seems to help a little bit, but overall the IMS module still crashes when I move the source around the blocker.
Usually the plugin can be fixed by simply stopping and starting the raytracing module and the on-the-fly aurualization. Do you guys know what might cause this problem? Any possible loophole in the raytracer in the case of multiple bounces? Thank you!
