A multiresolution tool and a personal goodbye

In this post we´d like to show a short tutorial on how to use the new multiresolution tool that is included in the latest build of the 3D extension for gvSIG 2.0. We can see how working with a huge dataset of points can be very taxing for the performance, making the system unresponsive and difficult to work. This new tool allows us to massively improve the performance with a very small hit on visual quality. We hope this tool can be useful for you!


I´d like to use this post also as a personal goodbye. It´s been a fantastic time here working in the AI2. Who´d had said I´d be working here for so long when I joined the team as an intern to work on my Final Project 5!! years ago?
Time passes quickly and now it´s the moment to move on and try new challenges. Here I have worked with an amazing group of people and I´d like to have some words for each of them:

-Rafa Gaitan, you are probably the most talented person I´ve had the chance to meet. As a boss, you´ve been always very helpful and understanding, knowing how to get the best of all of us. I´ll never thank you enough for the countless times you have helped me to solve problems in a matter of minutes that it´d taken me days.

-Jordi Torres, you had a tough job when you inherited Rafa´s position within the team, but you knew how to keep the unity in the team and have become a brilliant team leader in the end. I really appreciate the hard work you have been doing to keep this boat afloat in this difficult moments. The group is in good hands as long as you´re there.

-Maria Ten: You were the first to leave us some months ago, but even so, whenever we have needed your help you´ll find the time for it. I know it must´ve been a little hard to be the only girl around here, even if you won´t admit it. It was a pleasure to work with you!

-Leonardo Salom: We have never worked in the same project, but we´ve shared each other´s successes and frustrations. I want to thank your support in the difficult moments, as you´ve always been there.

-Javier Lluch: Thanks for giving me the oportunity to work here and thanks for trying to keep the group as long as has been possible. Congratulations for your new job!

-Jorge Izquierdo: The last to arrive and altough we haven´t worked in the same project, I enjoyed our conversations about technology, videogames, etc (politics not so much, hehehe) I think you are very capable person, with the right attitude you´ll do great.

I´d like to mention too some people from the AI2 with whom I´ve had very good moments; Enrique Medina, David Anes, Eduard Martorell, Joan Blasco, Marcos Martí, Oscar Ripollés and José Luis Hidalgo.

To end this post, I´d like to say that even thougth I leave this job, I´ve been assigned as Mantainer of the 3D Extension for gvSIG 2.0, so I´ll still be part of the gvSIG project for the time being.

Good bye everyone and keep the good job!

New build of gvSIG 3D (number 1) for gvSIG 2.0 -- Codename "TITANIC"


We are pleased to announce a new build of gvSIG3D for gvSIG 2.0, available in [1]. You can download the package and install it from the addons manager. This version is ready to work with build 2048 of gvSIG 2.0 and probably with future builds.

This development has been possible thanks to Prodevelop and  the project España Virtual.

This time we'd like to thank to Miguel Montesinos, Nacho Brodín, and Viqui Agazzi. They walked with us this path.

But specially I want to remark the great work of Jesús Zarzoso, developer in charge of merging the code between osgVirtualPlanets and gvSIG. Well done Jesús!!
 
Among the new features, we shall emphasize:
* Big refactor of osgVirtualPlanets, the core of gvSIG 3D.
* 3D extension code from scratch.
* Lidar reading support (.las).
* Citygml reading support (.citygml)(see the video).
* Multiresolution capacities ( see the video ).
* New 3D symbology framework (see the video).
* New render system using shaders and avoiding the fixed pipeline. (see the video)
* netCDF raster and vectorial support. (see the video)
* Tile raster cache integration with gvSIG -raster libraries.

These development versions are oriented to test and evaluate new functionalities of gvSIG, so it's not recommended to use it in a production environment. Please consider that it is an alpha release so don't expect it to be very stable.

Massive LiDAR data in gvSIG 3D!!!

Hi all,

This is the last video we did for España Virtual Workshop. It shows gvSIG 3D and osgVirtualPlanets drawing massive vectorial data without losing render performance using multiresolution and memory pagination techniques.

This work has been done in the scope of the Ph.D. thesis of Rafa Gaitán, so a lot of kudos to him!! The video speaks for itself...

improvements in 3D symbology

Hi Community,

Following video shows the improvements we are doing in symbology for gvSIG 3D in gvSIG 2.0 series. We added a new symbology panel (still in development) for 3D symbols. Now you can symbolize your layers with simple markers, picture markers, 3D objects and particle systems... :)

These advances came with "España Virtual" Project, and right now we are working towards an alpha release of the 3D extension for gvSIG 2.0.

Last workshop of "España Virtual" project

Hi all,

We just came back from the last workshop of "España Virtual" CENIT project. It was held at IGN (Instituto Geográfico Nacional) headquarters in Madrid. We saw very interesting and high-level presentations from the members of this project, and we tried to do our best in our turn showing our last developments... :).

We were glad to see gvSIG and specially gvSIG 3D being used in very different scenarios, from scientific visualization to building representations.

From this blog we want to thank all this people (administration, companies and universities) for making this project possible and for pushing gvSIG and gvSIG 3D.

We'd like to thank to Prodevelop for trusting us in this adventure. Specially to Nacho Brodín, Viqui Agazzi and Miguel Montesinos. Also thanks to the people of Deimos for their patience and their great work coordinating this project (specially to Jorge Blanco, Miguel Lizondo and Carlos Fernandez).

We will show some of the work done in the scope of this project in future posts.

Improvements in elevation layers

Hi community,

This new video shows the new system to load elevation layers and how osgVirtualPlanets deal with overlapping layers. Before this change gvSIG 3D (gvSIG 1.x series) cannot show the overlapping zones and the rendering was done using fixed pipeline, now (gvSIG 3D for gvSIG 2.0 series) this areas are merged in realtime in a terrain shader.

There are changes in lighting calculation that give the 3D view smooth shading feeling and a better appearance.

We'd like to thank to Maria Ten for her work, and we wish she feels great in her new job.
Thank you and good luck Maria!!! ... :)

gvSIG 3D Team at "España Virtual" Workshop

English

This week we have been very busy attending to the "España Virtual" Workshop[1]. As many of you know this CENIT project supported by CDTI[2] and leaded by Deimos-Space[3], aims to push the state of the art of geomatic science in Spain. In the scope of this project we are developing hard in several lines of work. In this post you will be able to see a few videos of some of them.
  • Advanced Symbology: We added new render techniques to the osgVirtualPlanets library[4], the core of gvSIG 3D. These techniques let us to render new symbols with a quite good frame rate. In this video we show point sprites, particle systems and instanced rendering. We hope we can integrate these functionalities soon in gvSIG 3D. 
  • Multiresolution of vectorial data: One of the problems we have in the current version of gvSIG 3D is rendering big amount of vectorial data. Is a must to apply multiresolution techniques in order to avoid RAM memory problems and low frame rates.  This video shows a quite popular spatialization algorithm called Octree.  It could be very useful to render regular massive vectorial data, for example Lidar data.
  • Collaboration with a friend project, WebGLEarth[5] : This project enables exploration, zooming and “playing” with the globe in any web browser on any platform supporting webGL (like chrome 9[6] or firefox 4[7]). We are collaborating with them and we have implemented zoom and pan controls, and camera throwing. It is a very promising project.

Español

Esta semana hemos estado en el workshop del proyecto "España Virtual"[1]. Como muchos de vosotros sabeis, este proyecto CENIT iniciativa del CDTI[2] y liderado por Deimos-Space[3] pretende avanzar el estado del arte en el campo de la geomática en España. En el ámbito de este proyecto estamos trabajando duro en varias líneas. En este post podreis ver videos de algunas de ellas.
  • Simbología avanzada: Estamos trabajando en añadir nuevas técnicas de visualización en la librería osgVirtualPlanets[4], el núcleo de gvSIG 3D. Estas técnicas nos permitirán mejorar el tiempo de dibujado y añadir nuevos tipos de símbolos. En este video se muestran point sprites, sistemas de partículas e instanciación de geometría. Esperamos poder integrar estas funcionalidades pronto en gvSIG 3D. 
  • Multirresolución de datos vectoriales: uno de los problemas que tenemos en la actual versión de gvSIG 3D es visualizar grandes cantidades de información vectorial. Se deben aplicar algoritmos multirresolución para evitar problemas de visualización y memoria. En este video se muestra una técnica de espacialización de geometría bastante conocida, el Octree. Puede ser muy útil a la hora de representar cantidades masivas de datos vectoriales regulares, como por ejemplo los datos Lidar.
  • Colaboración con un proyecto amigo, WebGLEarth[5]: Este proyecto permite la visualización e interacción con un globo virtual en cualquier navegador y plataforma que soporte webGL (como chrome 9[6] o Firefox 4[7]). Nuestra colaboración hasta el momento ha consistido en la implementación de los controles de movimiento y el lanzamiento de cámara.
