I have a coffee tag plugin that distort a the object where it is placed, based on the matrix of a lot of Null objects that work like body parts. I think it is better than c4d bones, but the result takes about 12 seconds to calculate each redraw, so I think that a c++ deformer object could be far better. My problem is that I don´t understand howw c++ works exactly, and i don´t know how to get a cdl or xdl file.
I´ll post here the code for everyone later. Can someone transform it to c++ and compile it (for free, of course)?

12 seconds seems a bit much, even in coffee. Perhaps you could do with some optimizations?
What plans do you have for your plugin? Are you planning on making it free/commercial/open source?
To convert your code into a cdl/xdl file you will need a compiler such as Microsoft Visual Studio. VS will only compile into a .cdl file, so it would only work for PC
To compile your code into a .xdl file you need a piece of software called Code Warrior, which can compile into a Mac compatible plugin.
Of course, this will only work if you first convert your coffee code into c++ code, of course this would require experience of c++.
Any chance you could show us any videos or images of the plugin in action?

I know a little about c++. I have the sdk, and I have a free compiler found in www.bloodshed.net .But I don´t know how to use it for c4d.
This takes 12 seconds with a figure of about 3000 points.
With a figure of about 300 points you can work right, even in coffee.
Of couse, It will be a free, open source plugin (here you have the code). I will try to put it in a c++ pseudocode for an object plugin later. But i think now you can imagine what i want.

The only compilers that currently work with the SDK are Microsoft Visual C++ and CodeWarrior. I think that there is a free version of VC++ which you can use for non-commercial work, but don't remember the specifics.
Victoria 3 has 72712 points and, yikes, Miki has 115067! It needs to be tight code.

Hi Robert! I wanted to talk with you! So it´s easily tofind you here that in your own forum?
I was wrong with my estimation in points. I didn´t want to talk in Poser´s things beacause perhaps someone didn´t know it's figures. My "12 seconds" were measured woking : ) ! with Victoria 3. But with the P3 woman, it takes faster and you can work right, even with coffee. The result its very near to Poser's way. I haven´t got "miki", but I yhink in most projects you don´t need so much points, an hypernurbs could do a good thing. I will try now an option to import vertexmaps exported with a python, like I told you in the e-mail.
I think the problem in my code is that I have several iteractions, especially in taking the points from the deformed object and the default one. This is twice the work that a c++ deformer would do, taking into acount that c4d owns the default point and "projects" the deformed one. Perhaps in c++ it is faster to get the code in several objects (like the deafaul c4d bone) instead of one deformer that collects the position of other objects, like i currently do.
This way, the object could store his relative position (wich I get with: while(bon){ trans+=bon#ID_BASEOBJECT_POSITION;bon=bon->GetUp();}) before readding the points to deform. and the relation to vertexmaps could be done in c4d´s way with restrictiontags, or with a link in the attributes manager, or even with claude bonet tags, if it accepts to be linken to the new boneobject.
¿are you sure Bloodshed Dev C++ does not compile c4d files? It can import Visual Studio proyects and it say it works in the same way. I don´t know why, I have a problem to install Visual Studio. I will try again, but it would be better if someone experienced in c++ help me.
It would be great if Robert or someone else, especially someone who owns poser figures, try my tag. It is easy: you just have to put it on the mesh and rename some objects with bodypat names. It is easy to do a code to transform polyselections to vertexmaps very fast; I suppose you can do it in a few minutes, but I will post it later for everyone. then i have another code to create a null object that rèpresent each body part. then You select all the vertexmaps in your mesh, Add User Data - Link, and run my tag.
In the future I will do a code to automatically put the "bone" objects in Poser´s center of rotation, now I do that manually. It don´t have to be perfect to sea the results, and it´s like tweaking with the JointEditor, very easy.
Finally, you can rotate this objects and the mesh moves ok :) .
I think with this corrections in c++, it can work good withot changing the main code.
The main idea is :
=== First, getting the "virtual translation" adding the translations of all
the parents of the current calculated deformer,and putting it as
V0 of it´s global Matrix, getting the matrix Mnew, and the vector Vnew;
===Second, deforming each point this way:
deformed_point=Mnew->GetMulP(default_point-Vnew);
I will try to post some images or video or c4d scene, but I think I have explained well...
Thank you for your attention and replies. I hope you like my idea.
