We are pretty excited to now be supporting OBJ (object) files natively on the VX1. You can now export an .obj file from your favourite 3D modelling software (or just find one on the web) to your usb and then plug it in and display your file as a 3D volumetric image. Easy…
The majority of 3D animators and modellers would usually be aware of .obj files and most 3D modelling software allows you to export to .obj. Blender (which is one of the most used 3D programs for content creation) allows you to export to .obj natively. Some software packages such as 3DS Max may require a plugin to export to .obj sequences (for animation).
Example of exporting to OBJ and then displaying on the Voxon VX1
I wanted to find something colourful to highlight how good obj files can look on the VX1 and show how you can zoom into extremely great detail. I went to Sketchfab which has a plethora of downloadable 3D objects and animations and found a 3D scan of an Indonesian mask (click here to see the source file – Original Scan from by Chris Hartmann).
I then downloaded the file, unzipped it to a USB stick. The extracted the files should contain an .obj, .mtl and .jpg file (which is how it would usually export.) I then plugged in the USB and selected the mask file. Here’s what it looks like.
Yes, it also looks pretty funny when you see the reflection of your arms and legs in the pictured, superimposed with an Indonesian mask!
One of the advantages of using object files is that the level of detail can be down to the individual voxel, and doesn’t look like a ‘minecraft digitized picture’ when zooming in. Here’s what happens when we zoom in using the 3D Spacenavigator mouse.
Easy as that really… Custom content can now be created and displayed on the VX1 very easily.
If looking to export an animation, choose export to .obj and leave the files zipped. Copy to USB and plug it into the VX1. Select the folder and the animation should run automatically. In our last video tutorial Gavin showed us how to Create a 3D Animation Using Blender. In that example gavin exported to STL file (colour not supported in STL formats) but with this update, you can now create an animation in colour and export to obj.
We are constantly improving our software capabilities and user experience and now being able to support .obj files, content creation for the VX1 is even easier!
