ViewTec’s State-of-the-art 3D visualization

2010/09/14

Good news!!!! They’ve probably released this Geovisualization Engine long time ago (It used to be an ‘in-house’ software) but I have just realized. I worked with this state-of-the-art TerrainView 3D software for six months while I was working as a GIS Specialist in Cape Town (South Africa)… What does this software has that no one of other softwares I know have????. Rain, snow, clouds, wind… Athmosferic conditions!!!!  A very reliable package… I have just uploaded a video rendered directly from a pre-recorded flight path… I will try to make my own while I work with this personal license key they have provided me for one month… Here it is!!. Hope you like it mates!.

Visualizing LAS LIDAR data with sketch-up

2010/07/02

While trying to figure out the way to get a 3D model from raw Lidar data, I first opened my LAS file in Global Mapper, exported it to DXF, imported then into Sketch-up and after recording a few scenes, I saved the animation… this is it!.

Ever tried Google Earth 3D Building Maker?

2010/02/18

I started modelling 3D buildings quite a few years ago, I used to use 3D StudioMAX… After almost forgetting everything i knew about modelling, 3D and so on Sketch up was released by Google. In a few days i was not just making demos but working and producing!!! Its extremly easy!!!!. Now They have just released something called “Google Earth 3D Building Maker” and its amazing, theres no need to know anything about modelling, you just have to insert polygons and move vertexes…very intuitive indeed!.

place the number of polygons you need…move their vertexes to the proper position.

Directly upload it to your Google 3D warehouse…

And finally take a look at it inside Google Earth… that’s it!.

You can always use Sketchup to perfect it… but it’s good enough…a piece of cake!

Some of the buildings located in Madrid and Cape Town are mine!

More of my 3D video edited scenarios.

2009/08/16

Please, dont forget to turn on your speakers. Even if i first used a different score and Youtube’s elfs told me not to use it (because of copyright authoring) I have chosen this music from their stuff and this is what I finally got…

Hope you like it.

Some of my 3D scenarios

2009/08/16

Barcelona (Spain), Winnipeg (Canada), Las Vegas (USA), Moscow (Russia), Durban (South Africa), Vancouver (Canada) and Tokyo (Japan)… these were some of my Terrain view’s 3D scenarios published by Computamaps, a South African company I worked in not so long ago. By the way it was one of my best professional experiences ever… I enjoyed joining them a lot and It was very difficult leaving them (mainly because of Cynthia’s fruit salads;-)… Miss you guys a lot!!!

Hope you liked them.

Getting textures from Google Maps – Street View

2009/08/05

I this post I am trying to show you how easy is adding a building to your scenario using textures from Google Maps (Street View). You have to know a little bit about Photoshop and layers and these stuff but it’s pretty easy thou…

First step, capturing my screen…OMG!!! there’s a tree in the middle of the building I want to model… there is no need to worry about it… Photoshop deals with it very well!!.

vic01_old

vic02_old

vic03_old

And after taking these three pictures I finally get this one (Thank you Photoshop!!!)… I could have done it much better but this is just for you to know the way to do it… its not that bad thou!

vic_lat_def

Second step: Start modelling… Im not teaching you how to model but I can tell you it’s a piece of cake… just try it. Of course I am using my beloved Google Sketchup. I get my current GE’s view:

defi01

Defining XYZ axes, first blocks… just starting dudes!…

defi02

Applying textures I had already got from Adobe Photoshop…

defi03

defi04

And after a few minutes modelling this is what I finally get:

defi05

Hey, It looks like more or less realistic!!!

defi06

Third and last step: Let’s go to Google Earth…

defi07

defi08

These two blocks of buildings are very close to where I live here in Madrid. Vicálvaro is 10 minutes to Madrid downtown by car… It’s far away but now it’s in your computer…cool, isn’t it?.

WMS in Google Earth.

2009/08/04

I have thought there is something very interesting maybe you guys have never tried… using your Google Earth sesssion not just for navigating, finding your house or the place you are going on holidays to… If you use the WMS protocol to show your map over your 3D scenario you are going to add a little bit more of interest to your Google Earth… Lets add a Corine Land Cover Map over my 3D map…but, What is WMS???, What is Corine Land Cover???. Im not even trying to tell you by myself, I am opeining my WIKIPEDIA to tell you, hehe…

WMS

A Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database. The specification was developed and first published by the Open Geospatial Consortium in 1999.

CORINE LAND COVER

CORINE (Coordination of information on the environment) is a European programme initiated in 1985 by the European Commission, aimed at gathering information relating to the environment on certain priority topics for the European Union (air, water, soil, land cover, coastal erosion, biotopes, etc.). Since 1994, the European Environment Agency (EEA) integrated CORINE in its work programme. EEA is responsible for providing objective, timely and targeted information on Europe’s environment.

This is the Official Corine Land Cover key map.

LEYENDA_CORINE

This is the area I would like to know more about, Chiclana de la Frontera in Cádiz, SW of Spain.

chiclana01

This is once we get connected via WMS to the place where you can get those maps (http://www.idee.es/wms/IGN-Corine/IGN-Corine?). By the way you can search on the internet to get more maps… you just have to go to google and search for ‘wms maps’ and you’ll be able to find them. This is a Corine Land Cover Map with information from year 1990.

 chiclana02

This is a Corine Land Cover Map with information from year 2000.

chiclana03

This is what we find after comparing both images… I have compared them using Photoshop CSX but you can go further and use global Mapper, ER Mapper or ArcGIS… As you can see, those areas highlighed are the areas with changes (very small in this case)…

More geographic post to come very soon!!!

Georreferenced pictures. Geovisualization live!

2009/08/04

You find a picture you like and convert it to 3D in a few steps:

Step1: Find a picture you like:

arroyo_05

Step2: Now Open your Google Earth and go to Tools/Add/Photo:

Untitled-1 

Untitled-2

Step3: You have it with the same perspective… you can even navigate inside the picture… This is just within a 3D model, now imagine if you have pictures from your trips… you can share their position with your friends just saving these files into a KML!!!… We’ll check it soon!.

Modelling Madrid 3D. Geovisualization live!

2009/07/29

And now, Let’s start with a 3D model… this is not very simple thou…

First of all we have a flat /2D scenary at GE, no much more than 50 cm of resolution. The place is very close to Madrid downtown, a very big neighborhood called Moratalaz…we will find there two very big towers of about 50 meters high:

torres01

As I said in the last post now we first open SU (Sketch-up by Google) and click on ‘get current view‘… This is more or less what we will find:

torres02

Let’s start modelling…I’m not telling you here the way you should model it… I’m just telling you that It is a PIECE OF CAKE!!!!!!!… This model has thousands of pieces but I just spent about 15 hours in modelling them all…

I have used something called ‘components‘… this means that you -for instance- design a floor and later on you can repeat it as much as you want… all you change in that floor will be repeated in the rest of them… didn’t I tell you that it was EASY???… Let’s stop saying nonsense and check it out!

torres03

torres04

Now let’s texture it!. As this is not an architectural model, this is just a building we want to visualize in our 3D scenery (now you know something else about geovisualization, nothing to do with Architecture as you can deduce from it)… we have just used a few textures (less than 5, more than 2…a few! I told you!).

torres05

torres06

torres07

Now that we have just added textures all we have to do is clicking on ‘place model‘ in our SU:

torres08

And finally switching to our GE to check it out…

torres09

torres10

Exactly georreferenced at 40°24’21.08″ N – 3°37’30.22″ W…

Do you like it?. It’s not that difficult isn’t it?. Do you dare to do something similar in your country… I’m sure yes!.
