Real time 3D Web Client Software and 3D City Models (highly detailed content)
December 2012

Dear reader,

we have been celebrating our tenth anniversary in 2012 and we have developed our concept of realtime 3D client software and tools since 2002 succesfully on international markets for leading customers in CAD/GIS or Internet growth entrepreneurs. Bitmanagement evoluted technically each year and augmented its portfolio by 3D content generation in 2011. Therefore today we can develop a relevant full 3D project "all-in-one".

Merry Christmas and a succesful new year 2013

Best regards,

Peter Schickel

Real touch on Windows 8

BS Contact supports touch functionality now also in 3D in desktop mode. Windows 8 has been especially designed for hybrid users, both for their daily work on the desktop and also on the move for quick browsing with touch input in the metro mode. You can use raw input as well as touch navigation with windows 8 in BS Contact.

Realistic lighting - New leap forward - interactive and online

BS Contact 8.1 supports deferred rendering with a new lighting and shadow experience.

Deferred rendering or deferred shading is a magic word in nowadays computer graphics. In principle it is a method to separate the geometry calculations from the computation of lights. Modern graphics cards can do these calculations faster separated than the renderer as a piece of software on the computer. So, many hundred lights are possible in one scene. The following screenshots shows about 250 lights with high interactive frame rates produced in realtime on a laptop computer with BS Contact in DirectX within a high resolution city model. Who can remember the old restriction of only 8 lights in OpenGL?

The image above shows a scene with light features. Instead of directional light, spotlights are used that stem from light bulbs on ground. Also the light is cast on the trees from the ground to make them appear in the dark.


Realistic motion - Avatar Locomotion – Your avatar finds its way in a scene

Realistic motion of avatars is now easier. In architectural scenes you want to add some life. This task is now straightforward with the new locomotion system for avatars in BS Contact 8.1

Your avatars will walk freely and find their way automatically over steps and little obstacles. So you provide only a path for them and you do not need to care about the movement.

Realistic reduction – fast and online

In order to optimize the download rates in the R&D project FINE Bitmanagement has implemented a clustering decimation algorithm that subdivides the 3D space into the cells of the user defined size. The original vertices of the mesh are checked for their proximity to the nodes of the virtual grid. The vertices placed closest to the nodes of the grid are left in the mesh. The rest of the vertices are removed. This algorithm provides a uniform distribution of vertices of the target mesh, even if the vertices of the original mesh were not placed on a raster.

BS Contact Mac now additionaly in Safari, Firefox and Chrome

The BS Contact Mac 3D engine supports now additional to Safari also Firefox and Chrome as browsers on the latest operating systems Lion, Snowleopard and Mountainlion.

Optimizations in BS Contact under the hood

Parallel loading – reduces waiting time
Loading in BS Contact has been optimized. You can load up to 8 instances in parallel now, if they are represented in inlines(). Objects can be accumulated in parallel now, that reduces loading time.

Inline Manager – Garbage collector for your inlines
Sometimes dealing with many large inlines, it is hard to load and unload them in order to save memory in the scene. This task is now done automatically with the new inline manager that acts similar to a garbage collector and takes care of your inlines if memory limits exceed 1 GB.

Improved geo navigation in BS Contact GEO - Geowalk
BS Contact Geo has an improved Geonavigation to navigate with accurate map projections. In addition to the Geofly mode you can also use the Geowalk mode now to walk on an earth surface or in the streets of a city model.

FINE-EC project results presented

The Free-viewpoint Immersive Networked Experience project is focused on developing a novel end-to-end architecture for the creation and delivery of a new form of live media content. FINE will deliver live content to professional and home users which will be able to interact and freely explore a live-action 3D scene. The results of this year were presented at the NAB Show in Las Vegas and at Siggraph in Los Angeles.
