New Genesis 3/8 compatible versions of mcjCollider are now online - PC 32bit PC 64bit and MAC 64bit 

https://sites.google.com/site/mcasualsdazscripts2/mcjcolliderds45

________________________

version history

2019 Feb 15th - Genesis 3 or Genesis 8 figures had facet groups that didnt match bone names and made the script fail, now the plugin looks for alternate names, for example, the pelvis bone can in some cases have its facet group named hip or even Hip

2019 Feb 9th - MAC version 64-bit

2012 Nov 30th - initial release
________________________

my first ds4.5 plugin, yay,

for a few years there has been a plugin for DS3/PCWIN named mcjCollider,

it's more a service than anything

you select target objects in your scene and add an mcjCollider in the scene,

it looks like a white ray

you point the ray at the target object(s)

activate the mcjCollider

and it very quickly jumps to the surface of the target object

the ray is also oriented as if it had bounced on the surface

---

in expert hands, or with the help of a script, could do interesting things

like fix poke-trough issues !!!

---

soon the version for DS4.5 will come out

in fact it already seems to work, as shown below

    Wondering if this might work on my ParticleFX and Genesis or other things...?

    next , i'll do a test on the basic Genesis

    i'll publish the source code, so if your programmer wants to include collision detection, it could help

    the mcjCollider node could also be "remotely operated" by your plugin

    test results, it works on Genesis figures

    i selected the torso nodes of the Genesis figure

    and created an mcjCollider node in the scene

    i pointed the mcjCollider ray at Genesis

    i ran this script

    
var collider = Scene.getPrimarySelection();
collider.activated();

    and the mcjCollider node jumped on Genesis and oriented its ray as if it had bounced (like a mirror bounce)

    the collider node communicates it's collision results using the label of a parameter named "report"

    usually this result should be of the format

    skeletonName / boneName / polygonType / facetIndex

    polygon types: 0 = triangle, 1 = quad

    so there's a problem to fix, here

    it should be something like "genesis abdomen 1 22988"

    in Stephanie (V4 based) collisions also work
    but i have to better understand how the new DzFacetMesh work
    and how the skeletons/bones work under DS4.5

    Freakin awesome...

    Well if you do give me the script I will give it to Vasily and he can incorperate into the plugin and you will get credit for the script...And I will send you ParticleFX DS 4.5 with a serial code that will expire in 9999 years...

    Genesis wearing a tube created using mcjCollider, mcjTransport, setInterpolation and the script below

    using a Null, i animated the camera rotating around Genesis, while going down, the collider was parented to the camera

    the script repeatedly "shoots" an mcjCollider at Genesis and moves the object named ball0 to the hit position.

    this animated ball is then used to make a 512 segments tube using mcjTransport

    node = Scene.getPrimarySelection();
ball = Scene.findNodeByLabel( "ball" + 0 );
tick = Scene.getTimeStep();

for( fr = 0; fr <= 512; fr++ )
{
 Scene.setFrame( fr );
 processEvents();
 node.activated();
 t = fr * tick;
 ball.setWSPos( node.getWSPos(t) );
 node.setLocalPos( t, DzVec3( 0,0,-10 ) )
 node.getXRotControl().setValue( t, -90 );
 node.getYRotControl().setValue( t, 0 );
 node.getZRotControl().setValue( t, 0 );
}

    DS4.5 is quite different from DS1,2,3

    i think mcjCollider for DS4.5 is almost ready,

    but i want to add functionality that will later make it usable for 3d painting

    i used the following code and the setup shown so project a cyan ball onto Genesis

    the second image is the view from the camera in the first image

    
node = Scene.getPrimarySelection();
ball = Scene.findNodeByLabel( "sphere" );
node.activated();
processEvents()
ball.setWSPos( node.getWSPos() );
node.setLocalPos( DzVec3( 0,0,-10 ) )
node.getXRotControl().setValue( -90 );
node.getYRotControl().setValue( 0 );
node.getZRotControl().setValue( 0 );

    Could it possibly eventually be used to create a mesh deformation brush or a displacement brush as well?

    (Zbrush like capabilities inside DAZ Studio? The mind boggles.)

    i made a plugin like that named mcjWarp for DS3
    http://sites.google.com/site/mcasualsdazscripts/mcjwarp-plugin-for-ds3-pc

    i will possibly make the DS4.5 version this winter

    and hopefully, add 'undo' functionality to it

    as some script-writers may know,
    we currently cant get the DzFacet's values ( indexes to vertices, normals, UVs ) using a script

    So the mcjCollider node will include a function to do just this

    example of the script to get facet[3] of the cached geometry for the node named sphere

    the primary selection is the collider note 

    
collider = Scene.getPrimarySelection();
node = Scene.findNodeByLabel( "sphere" );
obj = node.getObject()
mesh = obj.getCachedGeom()
debug( collider.getFacet( mesh, 3 ) );

    the result is of the form
    m_faceGroupIdx, m_materialIdx, m_vertIdx[0], m_uvwIdx[0], m_normIdx[0], m_vertIdx[1], m_uvwIdx[1], m_normIdx[1] . . . 

    
 0 0 4 4 4 19 19 19 20 20 20 5 5 5


    which will make possible the upgrade-to-DS4.5 of some really neat scripts like, for instance, mcjSpikey

    i had to study barycentric coordinates

    The collision detection uses the Moller-Trumbore algorithm

    Fast Minimum Storage RayTriangle Intersection

    ... and the new version of mcjCollider ( for DS3 and DS4.5 ) will report the UV coordinate of the hit point

    so this fall or winter i'll probably write a script or a plugin to do 3D painting!

    in the image below, i painted a cross in Paintshop, at the UV coordinate reported by mcjCollider

    and it fits !

    an mcjCollider parented to a camera rotating around Aiko's waist
    was "fired" 32 times, the UV coordinates of the hit points were then used to create red-dotted texture map
    (which was then reworked a bit in paintshop )

    all this to verify the validity of equations i use to compute those coordinates

    as you can see in the second image
    obtaining this "by hand" would not be a simple matter of drawing points on a straight line

    another test of the new mcjCollider feature: reporting of the UV coordinate of the hit point

    a script, using the services offered by mcjCollider, was used to create a texture map
    and placing heart "stamps" on the texture at the hit-point coordinnates

    it happened in past versions of Daz Studio too

    for some functions, the programmers forgot to do what's needed to give access to some functions and variables to the scripts

    they'll probably correct this in future versions

    but as i was saying my mcjCollider plugin will be a way to access the vertices/normals/UV indexes

    i want to post it very soon, i was distracted by my tests of the Kinect https://www.youtube.com/watch?v=wYEv7gtg68w

    sort of off topic, but got around to watching the dancing tests in your videos. i was wondering if you considered or know of a way to get the motion data from the popular MMD program over to .BVH format?

    i did my first kinect-MMD capture yesterday, it was surprisingly easy
    i saved the animation data and looked at it in notepad, it's in binary format
    but i do plan to look into conversion to bvh

    the first thing is to google it, there's very possibly someone who did it already ....

    indeed just now i searched for "vmd to bvh"

    most search results seem to be for bvh-to-vmd

    but i also see a youtube video titled "mmd motions in secondLife" and SecondLife uses BVHs

    note that there's free poser/DS figures available from SL, which can be handy for MMD and Brekel

    http://wiki.secondlife.com/wiki/Create_Animations_with_Poser

    my brekel BVH was targeting a SecondLife figure

    so i applied that BVH to the SL figure in Daz Studio, then saved it as a pose-preset, and then applied the pose preset to Aiko3

    interesting. i have seen somethings regarding converters for vmd <> bvh converters called "mio" and "b-momi", however the sites were in japanese. sounds like something to look into when i get things reinstalled. would like a "motion" avatar for the new forums.

    i downloaded mio-0.1.zip from here http://www.mediafire.com/?mdyzlml2waw

    it seems to necessitate the installation of many pieces, including Python.
    possibly as a way to get mac/linux/win compatibility

    they show their source code so maybe down the road i could adapt it

    Maybe a little off topic but have you heard about the Leap for Mac. It appears the SDK is also available on there site https://leapmotion.com/
    It only captures hand movements but its looking interesting.
