Re: [Bf-committers] Blender tangent space calculation
If it's not already available in the python API Hmm, I think not, as far as I can see in 'blender_python_reference_2_57' and by searching in 'blender-2.60a' sources. I've found only two files in sources with references to 'SMikkTSpaceContext' struct and to 'genTangSpaceDefault' function: - 'source/blender/blenkernel/intern/DerivedMesh.c' to get tangents for using in GLSL, I think; - 'source/blender/render/intern/source/convertblender.c' to get tangents for render's needs. But I not completely sure, I will look deeper. However, you'd need to supply support for normals as well since at this point the python API only gives access to the unconditionally averaged/smooth normals at the vertices. Ie. the api doesn't take faces set to soft/hard into account when submitting normals back to the script. Yes, I was wondering about that when started to write my own exporter since blender 2.49 :) But after I've found an 'EdgeSplit' modifier, I used to to export my meshes applied by it and to welding vertices and normals after. Maybe we'd can go a similar way and to provide tangents using averaged normals only?, since soft/hard edge's flags is 'de-facto' uses in that modifier only (as far as I know, even blender's render is not uses those flags). As about realization, I think it may be some analogue to the 'bpy.types.MeshTextureFace' class array, like 'MeshTangentFace' with four tangent vectors and fSign values for each vertex per face in it. Or with indexes to already welded ones. And generate data by request, in the 'Mesh.tangent_normals' accessor. Thanks.

Re: [Bf-committers] Blender tangent space calculation
There is no point in doing this unless you export the correct tangents and normals. That is the ones that were used to bake the normal map. I realize it blows that there is no API function to get the render normal. So what you have to do is produce it yourself like is done in DerivedMesh.chttps://svn.blender.org/svnroot/bf-blender/trunk/blender/source/blender/blenkernel/intern/DerivedMesh.c and many other places as well. An example in this file is the static function GetNormal() which is used as a call-back function by mikktspace.c and you can see how it uses the averaged normal if the face is set to smooth and it uses the face normal which it calculates itself if the face is set to flat. If you are going to make an api to export tangents I for one cannot emphasize enough that I prefer an all or nothing solution. Either do it right or don't do it at all. The last thing we need is to introduce a new tangent space standard within blender.

[Bf-committers] cycles fails to compile with jemalloc
Hey Brecht, Loving cycles btw :) I just was noticing the other day that I hadn't yet tried out jemalloc in the cmake settings. So I grabbed the latest git copy and installed it. The problem was that blender seemed to fail to compile. I don't have the compile error handy, but I recall it stopping on something cycles related, and went away when I disabled jemalloc. Anyways, just thought you might want a heads up in case you intended to support this malloc replacement, or at least allow cycles to work in concert with it.

[Bf-committers] Cycles movement blur
I was just thinking today that Cycles could do motion blur without taking a big CPU hit. I don't know much about all this so I bet my ideas is wrong or old but I thought I would post it just in case.

It struck me today that if at each cycle pass you move the object you would get a blur effect. I was also thinking that you might move it every 100 out of a 1000 pass to get interesting stutter effects. I look forward to hearing if my idea was good or only trash. BTW I would love to see a pause on the main render. Cycles eat my CPU alive and does not let me do much in the background.

Re: [Bf-committers] Blender tangent space calculation
I've said compilant as in I've tested with several meshes with automatic unwrapping (lots of seams) and baking from multires data and the result is perfect. I don't really know if it's really 100% compatible. I guess I must test with weird quads to be sure. In any case, I can tab - ctrl+t whenever I see a problem there. I'm just commenting that if you use ogre this shouldn't be an issue, but I completely agree that it should be a way to get exactly the same normals blender generates. 2011/11/15 Morten Mikkelsen mikkels...@gmail.com: You should be careful referring to them as compliant. I understand what you mean that they are compliant in format. But as is explained here -- http://wiki.blender.org/index.php/Dev:Shading/Tangent_Space_Normal_Maps the only way to be fully compliant is to use the exact same spaces that were used to generate the bake. This can also be achieved by using the referenced implementation (which is used in Blender) because it's designed to be order-independent and also independent of how the geometry is indexed or even indexed at all. Being fully compliant is what allows the renderer to achieve smooth transitions of normal fields going from one island to the next. This is important for characters especially.

One more question, if I may. I've seen that there is a couple of the exporter programs which can generate tangents to export for specific 3D engines only, like OgreExporter. So why not to simply adding possibility for generate/access a tangent normals into the python api? I am not saying that it very hard to generate those tangents using Morten's implementation directly in program, but think it'll be more a.. consistence and ease way for people who building their games to properly export their meshes :) Maybe if nobody wants, then I'd like to try implement this by some time.

I don't know much about all this so I bet my ideas is wrong or old but I thought I would post it just in case. When we do animation the computer calculates tweens and moves stuff for us. It does this once per frame. Cycles does many render cycles per frame. It struck me today that if at each cycle pass you move the object you would get a blur effect. I was also thinking that you might move it every 100 out of a 1000 pass to get interesting stutter effects. I look forward to hearing if my idea was good or only trash. BTW I would love to see a pause on the main render. Cycles eat my CPU alive and does not let me do much in the background. A nice/slow button might be good too but I am sure I am not the first to say this. Thanks for all the really cool work!! I love cycles, dynamic paint, motion tracking and ocean sim! All the other stuff is more in the background but I am sure I will be loving it too once I find it! -- Douglas E Knapp Creative Commons Film Group, Helping people make open source movies with open source software! http://douglas.bespin.org/CommonsFilmGroup/phpBB3/index.php Massage in Gelsenkirchen-Buer: http://douglas.bespin.org/tcm/ztab1.htm Please link to me and trade links with me!
