If you need ideas, then I liked ability to select camera position in Leap Service Provider :)

Yep, would be a good idea to be able to set a standard fps, like 24, 30, 60 etc for recording. It might save some resources on very fast machines that are recording faster than necessary.

Concerning new ideas, I suggest to implement a better UI, maybe based on OpenGL... there are a few open source UIs out there. https://www.slant.co/topics/748/~best-guis-for-opengl

Hi, i was searching in the doc of Leap Motion, it's posible to change the orientation of the leap. The gui i want to use ImGUI, it's easy and i was used in other times.
Thanks for the comments.

ImGUI would be great!

Developer

Added ;)

Final Version of GUI.

Developer

Today new Release again!.

Tracking of Thumb finger corrected.



Wow, that was really fast! 

Developer

New release today.... Thumb tracking corrected, and new features...


Developer

New Release, now yout can select the output frame rate.

Thanks for the update with the new GUI and FPS settings. It looks great and adds to convenience.

I have a few more issues...

1. I see 4 hands and 4 shadows in the viewer. Why 4, not 2? What is the significance of the second pair of hands? Having 8 hands (inluding shadows) moving is a bit confusing at times. Shadow display could be an option to be turned on/off.

2. It would be good to have an object or two in the viewport, which one could touch and manipulate. Something like, a ball, a pencil, a book, a cup, a monkey head ;-)  ,  etc ( it could be user selectable). That way one could simulate and record the movements in   handling common real worls objects.

4. It would be good if the window and GUI state is saved and resumed upon program restart, so one could resume work without arranging things again.

3. How about providing a direct data fed into Blender? Is this feasible?

Thanks

Hello everyone. 

1.- There are 2 pairs of hands because 1 is the API that shows the output of the LeapMotion and 2 is the BVH with the movements of the API plus the options correction. if your are confused, you can change the .OBJ file of resources/objects/bone.obj. It must have a texture and be triangularized.

 2 The inclusion of objects with physics can be done but it would slow down the process a lot.

3 It could be done, it is more I have thought about it but I like it more so, I do not know the Blender so deep or the python.

4 It is created with the Save config button.

Thanks for the comments.

(Thanks to bing translator) :) 

Have Fun!

Hi totalvortex, thanks for your explanation. Now that I understand, I will have a closer look on the benefits of having two pairs of hands. But still, could you make the shadow a toggle option?

About physics objects in the viewport, I wouldn't mind a little slow down. If my systen couldn't handle it, I would prefer an upscaled system, not a downscaled software. I have other leap motion software that has a dozen simulated objects in the viewport and there is no performance problem. I find it difficult to simulate e.g. a writing hand without actually seeing the movements of the pencil it holds. If this can be aided with a simulated object, it should definitely be done.

Regards

Developer

The shadow checkbox it's now active and you can see only the BVH.

About the physics it's not simple. I must to control the collisions and its a little dificult.

Next release will have a BVH parser im working on it.

See a screenshot.

Great, thanks for the shadow option. Yes, I understand that object collision is not a trivial matter. So maybe in some distant future this could be implemented. 

Developer

the next step I have in mind is to simulate the hands with the armature to use. That is, you load your armature (body) and join your hands with its scale and such.
Please download the new Release its one of the best.
Thanks for the comments!.
Have Fun!.
:)

Developer

PD. The BVH templates of BVH hands files must be in the BVH directory (security reasons)).

About the object collisions....

New Release! Custom hands.

Be fun!

Developer

New Release compatible with Gemini drivers.

Have Fun!.

Hello! Thank you fr your amazing tool, but i confuzed with one thing. HAND1 has a bit twitchy and incorrect animation (look video), while HAND2 motion is pretty smooth. Is there any way to export to bvh exactly HAND2 animation?

Developer

Hello, and thanks for the coment.
Try to load the other template of hands that are in the zip file and reajust thumb options (F1).
It depends of the thumb finger start. If the Leap Motion dont see this finger it moves a little crazy.

Developer

mmmmmm it's posible, but I must create the armature with the program, but it's posible!, next releases could be.

Developer

Try the new Gemini update. It take the rotations from the bones of the API.
Thanks next time i uploaded a template for the API hand.

Have fun!.

Developer

testing the BVH parser....
