Michel Anders (varkenvarken) added a comment to T58734: bvhtree.fromObject - error ( returned NULL without setting an error) in blender 2.8.

great! works like a charm now :-) (tested on linux 64bit)

Michel Anders (varkenvarken) created T59889: Second call to BVHTree.FromObject with the same object results in a segmentation fault.

Michel Anders (varkenvarken) added a comment to T57861: Object.ray_cast (and all RNA functions using "ob->runtime") broken in Blender 2.80.

Just tested it with the daily build (blender-2.80-e4dbfe0a98c1-linux-glibc224-x86_64) and repeatedly ray casting on the bvh now works but if I invoke the operator again (and create a new bvh from the same object) I get a segmentation fault. I'll create a separate bug report that references this one just in case this is not related.

Michel Anders (varkenvarken) added a comment to T59869: BVHTree.FromObject crashes with pthread priority assertion when called in quick succession on same object.

PS> this might be related to https://developer.blender.org/T58734 but note that in that report the call reproducibly crashes on the second call whereas in this report it might take anywhere between 5 and 30 calls (depending on how quickly the calls happen?)

Can confirm this on Ubuntu 18.04 / GTX 1080

Michel Anders (varkenvarken) added a comment to D1463: Expand Voronoi node functionality in Cycles.

@Sergey Sharybin (sergey): I reconfigured CMake to generate the .cubin files (instead of generating them the first time the GPU was selected) and verified that a number of kernels was generated : sm_20, sm_21, sm_30, sm_35 and sm_50, both the plain and the one marked as experimental. (a GTX970 supports sm_52 as well but I didn't upgrade the cuda driver on my Ubuntu system so I had to exclude sm_52 from the make files). The make succeeded cleanly.

Ok, I extended the node as discussed previously. A few remarks:

Michel Anders (varkenvarken) added a comment to D1463: Expand Voronoi node functionality in Cycles.

ok guys, i see some agreement starting here ;-) I'll start on a new patch that will extend the current voronoi node without breaking existing stuff . I'll do my best to make it run on cpu, cpu+osl and gpu (nvidia + amd) and then submit it for a thorough review.

I think the suggestion by SynaGl0w ( http://blenderartists.org/forum/showthread.php?378351-Extending-the-Voronoi-texture-node-in-Cycles&p=2922699&viewfull=1#post2922699 ) makes sense.

Because quite a few people are convinced it would be a useful addition I went along to give it a second try :-)

Michel Anders (varkenvarken) added a comment to D1463: Expand Voronoi node functionality in Cycles.

@Thomas Dinges (dingto): I have no opinion on the kernel split issue because it is difficult for me to have any idea of the impact on individual node code, but I agree that on the second point that we wouldn't want to have the profusion of options that BI has.
However, for most people (at least in my neighbourhood :-) F2 is perfectly logical when dealing with Voronoi textures and it would in fact be more logical to rename the Fac output to F1 but I think that would break existing noodles that use the current voronoi node, right?
Another approach might be to create a new 'Crackle' node, which delivers just F2 - F1. After all the goal of this exercise is to provide artists with exactly that texture, not to complicate existing nodes. I would be happy to provide a patch for such a node if that would be considered cleaner (but it would add an extra entry to the the list of textures in the node menu, which is a bit of clutter in itself)

Michel Anders (varkenvarken) added a comment to T44890: Data belonging to unused appended group is impossible to delete from file.

I think this can even be done quicker by selecting ´orphaned data' in the outliner and clicking 'Purge all' (but you need to do that twice)
