Google Sketchup to Lumion

Now in its second decade, Google SketchUp has certainly come of age. In a past post I looked at importing SketchUp models into ESRIs ArcGIS  and now a look at working with Lumion 2. This demo is looking at an indoor scene aiming to introduce the viewer to an office and environment whilst highlighting some of the work being conducted.

The first image is a view of the office as it is being created in Sketchup and it is evident that the overall image quality is good but nowhere near realistic. Though this may be the case, the modelling process is so efficient that this was created in under and hour.

The next phase is the export from SketchUp and import into Lumion. This process is particularly simple and relies on the use of the COLLADA file format. Using the menu File > Export > 3D Model. In the save menu it is then important to set save options to include 2 sided faces, export edges and triangulate all faces.

Once in Lumion the import process is fairly simple. In the objects menu select import file and then select the COLLADA file. Important consideration at this point is whether to create new textures with Lumion or use the default Google SketchUp.

The video above has been created using the Lumion video engine and exported at 720 dpi.   The video maker allows a simple screen-grab based approach to creating a path and then intelligently renders a path between them. The video editor has significant functionality and allows people, vehicle and object animations to be included.

A few faults evident in the video was the flickering on the Mac and tv displays which was a result of multiple textures on the same plane. This may be alleviated by lifting the primary texture.
