Practice your 3D modelling with a 3D Jack-O-Lantern
Modeling a pumpkin and carving out a face is a great way to learn multiple workflows one after another in SketchUp!
10 steps to creating your very own 3D mask
Step 1 : Create a scan of your face you can model off from. Use Structure Scanner to scan your face and then import it into SketchUp! Importing the STL file only takes a few seconds. Group the geometry and run Soften/Smooth to improve the aesthetics.
Step 2: Create a rough outline of the mask on your face. To do this, align your parallel perspective camera straight-on to your face and place a reference plane (just a plain old rectangle) in front of the camera. Since I wanted to see through the rectangle, I filled it with a 50% transparent white
Step 3: Draw a basic outline of the mask shape you want to create You can use SubD to smooth out the final mask lines.
Step 4 : Ensure that the outline is made of quads (this means the model faces are made of four-sided shapes). You can also use component mirroring to model and maintain symmetry for your mask.
Step 5 : Use Push/Pull to extend the shape of the mask through the face scan. Since the model of the mask would eventually be intersected with the scan geometry, it is important that the mask geometry pass all the way through the head. Fortunately, pushing objects through a human skull is far easier in SketchUp than it is in the real world.!
Step 6 :Start sculpting with Vertex Tools to shape the front face of your mask. You can also use SketchUp's native Move tool, but Vertex Tools assured that the quads were maintained. This is probably the most time-consuming step, but also the most important, as it establishes the character of the mask.
Can you guess which character's mask this is?
Step 7: Improve your mask geometry using SubD. This was actually a back-and-forth process combining Vertex Tools, SubD, and the Crease Tools (in the SubD toolset). As the geometry comes together, some surfaces run back, through the face scan. T
Step 8: Intersect the geometry of the mask with the geometry of the face scan. Use Intersect with Model. After that, all of the extra geometry was deleted.
Step 9: Use Solid Inspector2 to make sure that the mask is printable. There may be some gaps in the model that had to be patched before it was a printable solid, and ultimately a 3D-print-ready STL file.
Step 10: To make it "real," open the STL file in FormLabs's PreForm software.
PreForm from FormLabs helps you orient and prepare your model for stereolithography printing.
Time for printing the mask in 3D! Use Form2 to make this digital dream a reality! The precision of an SLA printer ensures a very presentable 3D mask. The resin used in the Form2 is sandable and paintable! If you are keen to get a trial account of SketchUp, ping us here!
