first and a second in pdf format

 Hi 

There are all three examples within the one document. The third example attempts to explain the group index ...

Yes I agree, what I am asking for, is for the next level of development. I wonder what it will take for the developers to have the group index parameter in the 3d model player. 

I appreciate all that you are sharing on this, parallel with your explorations.

You mentioned the tutorial to be third in the package. Is there a first and a second in pdf format as well?

The skeleton is a free download. I applied the inverse kinematics for the walk cycle in Blender or Cheetah 3D ( can’t remember which one). I am unable to offer the geometry other than the link above.

Hi, is there any chance to get access to the walking skeleton cycle as a 3d- model. I remember, when I had Poser, it was part of the walk-designer...?

Please have a look at the image attached. Let me know what you think.

You ask very practical questions about the axis of translation for each discrete piece of geometry. Unfortunately, I do not have the answers for you. I have not had the opportunity to investigate the level of detail you are requesting and as you have found out there is no user manual currently available for this parameter. Of course, I would like to know these answers as well. It appears so much of the orientation is inherited from the 3DS file and it would be fantastic and so much more efficient if the orientation to translate the geometry, as described in your example, is simply imported into Isadora with the file. My time has been spent developing a program to make it work - you are asking questions about the next step in the development.

Perfect! Just what I needed :) This is going to be so helpful. Just downloaded the good stuff.

Thanks

Hi,

It will require some trial and error development, and much of the capacity to achieve a satisfactory result will be dependent on the capacity of your system i.e. GPU and CPU etc.

I found there were definite limits and sweet spots for the number of vertices and what can be tolerated in terms of frame rate etc.

Here is a reference to a tutorial and download for resources that attempts to explain some of the system design that allows the ‘group Index’ parameter to be used in the way demonstrated in my videos. I created the tutorial (it is the third tutorial in the package) when I was just beginning to look at what the group index could do... so it is not a perfect tutorial and needs rewriting to be more accurate and clear in terms of the system design. However, it does demonstrate the user actors and system that I have developed to synchronise the particle emitter with the group index parameter.

I hope that it is helpful for your cause.

Hi!

Your example proves to a greater level of what can be achieved with the group index parameter. (I was struggling to even get started with it in a most basic patch of getting anything even appear on the stage).

I am figuring out a way to make 3 dimensionally oriented and distributed array of an object and then trying to manipulate each of these separately in Isadora. I am unsure if it is possible.  Please have a look at the image attached. Let me know what you think.  

Thanks and Regards

respective local axes when transformed, or will they respond to the world co-ordinates of Isadora

In 3D Model Particles the 'group index' will identify discrete geometries, or as merged geometry groups, by their index number (this appears to be inherited from within the 3DS file and therefore attributed in the 3D modeling software). If the 'group index' parameter is left set to '0' then all geometry in the 3DS file will be sent to the emitter at each instance. The implications of this are huge in terms of working with complex 3DS files in the particle generator. Because by limiting the particle emitter to segments of a complex 3D model in fast succession (triggering the emitter and 'group index' parameter at high hz values) you increase drawing efficiency and therefore possibilities for greatly improved frame rates and in addition the appearance of internally animated sequences of geometry. 

This youtube video demonstrates another approach to animated 3D models in Isadora.

working on Isadora 2.5.2. I just installed 2.6.1 and happy to see the group index parameter

 Glad you worked that out. I recall being surprised by discovering the parameter in v2.6, but had forgotten that it was not implemented in earlier versions.

Will there be an updated manual available for download soon? 

 There will be an updated manual available with Isadora 3.

If you realise how powerful this is and the potential awesomeness that it can facilitate you can help me to advocate that it does not disappear with the release of v3! Because it was missing in the last beta!

 It will return, don't worry.

Wow. How did I miss this?!

Hi! That's fantastic! This really opens up a lot of possibilities. I think this feature by itself is very powerful. I am wondering if the elements are oriented to their local normals and then exported, will they behave accordingly to their respective local axes when transformed, or will they respond to the world co-ordinates of Isadora.

As for the 3d model particles, I was reading the manual v 2.0 and working on Isadora 2.5.2. I just installed 2.6.1 and happy to see the group index parameter. I am glad you pointed it out, else I would've never known.

Will there be an updated manual available for download soon?

see a 'group' parameter in the 3d model particles actor

Hi,

Well, it is in fact called the 'group index':

For example, when I use a 3DS file and
target each element of geometry using
the 'group index':

I can start to generate effects like the
one captured in this Youtube video of
one of my patches:

This 3DS file:

becomes this Youtube representation
of one my Isadora patches:

Hi Michel! I live in Pune city. Thanks for sharing this. 

If there is a lot happening in India, then am afraid, I must be a frog in a well :) I must get off my machine once in a while and do some networking. I will visit the site and see where it leads.

:) hehe.. I am enjoying these interactions. On a personal note, I am alone in trying to figure out all these complexities.
I am not sure if you remember, I contacted you 3 years ago and then went on to learn Processing. It has been a long break!
There is no 'team' per say in and around here and is very difficult to find projects related to arts and pure visual delight, which can also generate revenue. In India its evolving slowly and mostly everything is revolving around commercial corporate boring presentations. Its a vicious cycle for my wish-ious circle..
Cheers
Saif

Forgive me - I get people contact me almost daily. I can't always remember names/user names/avatars! haha.

Glad to have you back, processing can work great with Isadora via Syphon/Spout integration. 

Were from India are you? I did a few Isadora works with Amitesh Grover, he is a theatre director and Assistant Professor at National School of Drama. https://amiteshgrover.com/abou...

Will look into it in depth. Pun intended :)

 haha - I like it. 

P.S.

I forgot to mention, the link for the video for the example, turns up 'content not found'.

@Skulpture 

The video-gen option seems great if I use animated texture maps in greyscale values. Although I understand we won't get a z-depth location for these particles. Maybe a combination of 3d models mapped with animated textures and these in turn getting generated using video-gen will give some awesome results! But the 3d model particles actor does not have a video-gen parameter... Will look into it in depth. Pun intended :)

@bonemap 

I don't see a 'group' parameter in the 3d model particles actor. Did I miss something here? 

Anyway, I will be doing a series of tests over the weekend w.r.t all this valuable information. Will share the results if anything worthwhile comes out of them. 

Cheers
