SimpleTree plugin: a tool for complete tree reconstruction (21 comments)

Added by Piboule Alexandre almost 8 years ago

Below, a message from Jan Hackenberg:

Dear Computree Users,

A new plugin is available for Computree. It aims to model the complete tree structure including every branch for a tree cloud. See the attached screenshot. As the output you get a so called QSM model containing up to multiple
thousand cylinders per tree. The plugin is based on http://www.mdpi.com/1999-4907/6/11/4245 which presents a stand alone software called SimpleTree (http://www.simpletree.uni-freiburg.de/). The SimpleTree method is now rewritten in Computree.

A lot of improvements have been performed. The method does not rely on user given parameters any more. All parameters are computed within the method itself. Before the next official Computree release you can already get access to the plugin in form of a Windows exectuable. It just contains basic Computree functionalities and the SimpleTree method, as this is only a partial release.

Please sent an email to to get access if desired.

You will be able to download from:
http://rdinnovation.onf.fr/projects/computree-simpletree-beta-version/files

Here is also a small Readme PDF which should be read first. It contains in majority (page 2 until end) screenshots and should be read fast.

Please provide me with your Computree/rdinnovation user name. Let me in addition know if you want to be put in a small newsletter, as I do not want to post too much on the Computree platform announcements.

I plan at least weekly releases of this plugin. De-noising procedures will follow. To improve the method you can do the following:
  • Provide me with feedback. In case you receive negative results, e.g. bad tree models, write me a short email with a screenshot of the modelling failure. If I cannot fix by the screenshot I will ask you to give me access to the cloud to reproduce the error and debug it.
  • If you have Tree scan data with GT (complete tree volume or biomass + density), it would be hugely beneficial to get access to this data. I will not publish this data without your allowance and use it for training purposes only (or ask for allowance).

Thanks for your kind attention
Jan

Computree formations (12 comments)

Added by Piboule Alexandre about 8 years ago

French (english follows):

Bonjour à tous,

Je fait cette annonce, afin de recenser les besoins de formation Computree pour 2016.

Merci à toute personne intéressée de m'envoyer un mail à l'adresse suivante :
Merci d’indiquer impérativement les informations suivantes :
  • Quel type de formation : utilisateur / développeur ?
  • Combien de personnes intéressée pour chaque type ?
  • Période idéale de formation / période acceptable
  • Lieu idéal de formation / lieux possibles (parmi Paris, Montpellier, Nancy en France ou Sherbrooke au Québec)
  • Langue de formation : est-ce que l’anglais est possible ?

J’espère fixer le planning de formation mi-février.
Il devrait y a voir a minima une formation utilisateur en France métropolitaine.
Au niveau international, des formations utilisateurs sont envisageables au Québec.
Par contre il semble peu probable de pouvoir faire des formations dans d’autres pays en 2016.
Du coup, s’il y a une forte demande hors France et Québec, nous nous orienteront probablement vers une formation à distance (webinaire).

Cordialement.
Alexandre Piboule.

English:

Hello everyone,

I made this announcement, to identify formations needs for Computree in 2016.

Thank to anyone interested, to send me an email at the following address:
Thank you to give the mandatory following informations:
  • What type of formation: User / Developer?
  • How many interested people for each type?
  • Ideal period / acceptable period
  • Ideal place for the formation / possible places (Paris, Montpellier, Nancy in France or Sherbrooke in Quebec)

I would like to fix the formations schedule for mid-February.
There should be a minimum of one formation in France.
Internationally, User formations are possible in Quebec.
It seems unlikely for me to be able to propose a formation in other countries in 2016.
So, if there is a strong demand outside France and Quebec, we probably will consider webinar solutions.

Best regards.
Alexandre Piboule.

News about next release (2 comments)

Added by Piboule Alexandre over 8 years ago

English: (French follows)

This announcement follows Silvilaser 2015, which generated new registrations.

You’ve probably noticed that the version of Computree downloadable online is almost one year old. This is due to the fact that we have made significant changes to the platform (ergonomics, performance ...) and many innovations, which require large stabilization efforts, which are now almost completed.

We are working also to increase the number of plugins available with the standard version of Computree .

I therefore announce a release soon, in the autumn (early November if all goes well...).

In the future, releases will be closer. Thank you for your patience.

Best regards.
Alexandre Piboule.

French:

Cette annonce fait suite à Silvilaser 2015, qui a généré un certain nombre d’inscriptions nouvelles.

Vous avez probablement constaté que la version de Computree téléchargeable en ligne date de presque un an. Cela est dû au fait que nous avons apporté de profonds changements à la plateforme (ergonomie, performances...) ainsi que de nombreuses nouveautés, ce qui a nécessité de gros efforts de stabilisation, qui sont maintenant presque terminés.

Des travaux sont également en cours pour augmenter le nombre de plugins disponibles avec la version standard de Computree.

Je vous annonce donc une release pour bientôt, dans le courant de l’automne (début novembre si tout va bien...).

Dans le futur, les releases seront plus rapprochées. Merci de votre patience.

Bien cordialement.
Alexandre Piboule.
