To scan a model 3DSOM Pro requires a number of photos taken around an object. These can be taken in a number of different ways:
From version 5, we no longer require printed calibration targets in the scene. Calibration targets can still be used for studio environments or very plain objects, making camera motion recovery more robust especially if you can’t take lots of overlapping shots. For the latter two approaches, a contrasting backdrop can be used to simplify masking in the next stage which allows the 3D model to be cleanly separated from the background geometry.
To capture more accurate geometry a projected stripe pattern can optionally be used. The stripe pattern is provided with the software as a slide for use with a standard digital projector. For each rotated position of the object 3DSOM Pro requires two vertically spaced views of the object illuminated by the projector.
With the images loaded into the software, 3DSOM Pro can automatically masks all the images (separating the object from the background) with a single mouse click. If the contrast between foreground and background is not great (e.g. you didn’t use a backdrop) then you need to manually mask between 5 and 10 “key” shots. The new masking wizard leads you through this process using our new “magic marker” tool.
A powerful set of manual and semi-automatic masking tools are also provided. Accurate masking in 3DSOM Pro can be achieved quickly and easily.
3DSOM Pro will automatically run the following steps….
Experienced users can intervene to edit the geometry, construct subdivision surfaces, combine multiple scans to capture the underside and edit the textures to change the model appearance using a comprehensive and powerful set of modelling tools.
Once you are happy with the model, it can be exported for import into other authoring packages and applications. Integrating 3DSOM Pro into your workflow is important and we have chosen a set of representative export formats that should meet your needs.
3DSOM Pro also supports our webGL format, allowing models to be published in your public Dropbox folder or uploaded to your website. WebGL models can be viewed in desktop browsers or mobile devices as an interactive 3D presentation. You can also upload straight to Sketchfab – a popular cloud-based 3D publishing solution.
