Re: Zbrush fibres to softimage strands
hey Juhani, thanks for the plug :) hi Gerbrand up to now i didn't have any problems with the compounds, except for one report that says that sometimes zbrush messes up the objs on export, writing some #inf's to pointpositions. then the plugin fails to load the obj. never happened to me though. if you encounter problems you can post them here, i'm usually around lurking in the depth of the list. cheers -- Flo Eberle Lead Modeling Artist/ Technical Director On Wed, May 9, 2012 at 12:19 PM, Juhani Karlsson juhani.karls...@talvi.comwrote: http://florianeberle.com/2012/02/21/fibermesh-to-strands/ These compunds work pretty good. : ) 2012/5/9 Gerbrand Nel g...@cannonballbunny.com Hey list I have a pretty tight project where I need to create a realistic animal and was wondering if anyone here has used the zbrush fibres to strands add-on?

[C++][CustomOp] - UV Cluster update problem
Hi list, Recently I have encountered with the problem that I cant update UVs and Usernormals clusters on the mesh. Situation is here: I have a some custom op connected to some original geometry ( input ) and setted on the some result geo ( output ). Work is going in the operator update callback. Topology of the result geo is changeable and can has more of polygons than in the original one. It also has a UVs and usernormal clusters ( both created as always completed ) which must be resized respectivetly to the topology changes. But problem is that nothing similar to resizing simply doesnt happen, when I have a result topology with a greater number of polys and try to update clusters values with UVCls.Set ( const float * _pValues, LONG nbNodes ) - I get crash. And at this time, GeometryAccessor reports a valid nodes count. Furthermore, if I call UVCls.GetValues ( CFloatArray ) I will get the size of CFloatArray is valid also. So, I cant understood what I am doing wrong or is it a bug. If topology is not being changed - UVs updates fine. I have also looked at this threads http://www.xsibase.com/forum/index.php?board=14;action=display;threadid=35564 http://www.xsibase.com/forum/index.php?board=14;action=display;threadid=41707 and seems like that my problem is the same. Are there possible workarounds ( even something like CCOMApiHandle ways ) ? Thanks, -Oleg

[mental ray] contrast check on framebuffers - causing artefacts/interference
I ran into an issue where there seems to be some interference between framebuffers - when I render individual framebuffers it’s fine, but when I render a lot of them at once, artefacts show up. (looks a bit like jpeg noise) I narrowed it down to the ‘check contrast on all framebuffers’ option, in the framebuffer tab, which is on by default. turning it off makes the artefacts go away, but the sampling quality is much lower. I cant recall this happening before, and wonder if its somehow related to unified sampling ? any pointers, other than not using mental ray?

ice attributes not showing up in render on refmodel?
hi I’ve got some characters with pointclouds in them, and in the rendertree I’m looking up a few (vector) attributes I added in the ICEtree. (non simulated) I’m looking up values from the emit location on the particles, eg. normals and UV coordinates in my case its working fine – but when I bring these models in a scene as reference models, the attributes dont show up at first. (it shows up as the default value when no attribute is found). when I go in the rendertree and select the attributes again manually (and thus create a delta) it seems to fix it – though I’m a bit worried as I have a lot of scenes and assets coming up and want something reliable – not something that will every so often ruin my renders. is this one of those ICE optimisations, where the attribute doesnt get created ?

Hi guys/gals! Has anyone actually tried to rig/animate a model using this fiber to strand conversion method?

Re: is it possible to define object labels?
Hi, I'm pretty sure you can't lookup user data with the built in shaders. However, as you suggest a simple ICE setup to label an object would allow you to write an object or poly context integer attribute, which could be brought into the render tree.

Re: Convert Position Fcurves key's tangents in 3d space
Thanks Simon!
I have a working version with tangents, but it crash softimage in some
cases, the std::vector is kind of touchy...
I also have problems with the opengl's GL_SELECT for picking that sometimes
return funky value (Thanks ATI...). It seems to be deprecated in favor of
custom raycast picking, so I'll refactor it that way.
I have a question to Softimage Devs, As I have selection problems for
components, am I right if I say that SI is also using GL_SELECT ??
I have seen some people saying they got 1000% speed gain using raycast
instead.
Regards
Ahmidou.

Very cool! So amazing to see this in Softimage! :)

Hi Jo, and thanks for the snipet!
I already have a structure not that far, but my problem is elsewhere. The
fcurves's tangents interpretation in 3d is not a simple mapping of the X,Y
values.
I also had to deal with fcurves that don't have necessary three keys a
the same time but only one or two, so I don't have all the information to
draw the tangents as they should be.
But I think I'm near the solution, I just have to restructure some part
of my code to make it more efficient and test :)
Best regards

Hi Ahmidou,
looks quite nice ! :)
For your problem, I would go in c by reproducing a kinda structure that
mimic FCurves ones like the following.
struct bezfragments {
double cps[4][3];
uint_t interp;
};
struct motionpath {
constchar_t *source;
ushort_t color[3];
uint_t flags;
uint_t nbezfragments;
struct bezfragments *[1];
};
A MotionPath as a FCurve is a fixed length array of bezier curves with
some extra informations like the object which is the source, the color of
the path and some other flags for ui convenience (selection mode, ...).
You have the choice to represent your bezier segments by pairing
control points by 3 or by 4, I dont think it makes a huge difference.
This system coupled with a MotionPathManager will avoid you to have to
query the softimage API each time you need to redraw your viewport as your
datas are cached in memory.
Also, by subscripting to any event like siOnValueChange, you will be
able to rebuild a motion path targeting just what you need. Also a good
point for perfs.
Anyways Here is a little pysnippet (I dont have the possibility to
write it in C right now) ! It should I hope answer to your first question !
:)
