About

Plastic

Create 3D models using volumetric primitives and boolean operations, not polygons. Apply color and make non-destructive edits throughout the entire workflow. Export your creations for animation, rendering, or 3D printing.

Highlights
  • Volumetric modeling with primitives
  • Add and subtract operations
  • Integrated coloring tools
  • Non-destructive editing
  • Export to PLY format

In contrast to most other modeling tools, Plastic does not use polygons to define the shape of an object. Instead, you build up a volumetric representation by simply combining primitives with add and subtract operations. The same tools used for modeling can also be used to apply color to the model in one continuous workflow. And, since all of these actions in Plastic are non-destructive, you can easily change aspects of your scene at any point without affecting unrelated work. When you are done, objects can be exported as PLY files to be animated, rendered, or 3D printed with the help of other tools. To get started, create a new project by tapping the “+”-symbol in the project gallery. To edit an object in the scene, you can either tap it twice in the outline or tap the “Edit” button after selecting it and switching to the attributes panel. By tapping the plus button in the outline panel, you can now add strokes to your object and build up its shape. Although I am trying my best to provide a polished experience, Plastic is still in an early stage in its development and occasional bugs, missing features, and frequent design changes cannot be completely avoided. If you are interested in updates on the development progress, feel free to follow me on Twitter @raffael_kaehn. For feedback, please send me a direct message or an email to feedback@plastic.app.

About

i3DGSLKG

Features
Read full description

This app displays 3D Gaussian splatting in 3D on a Looking Glass connected to the USB-C port. Please note that the maximum video output from the Lightning connector is Full HD (1920x1080) and cannot be displayed on the Looking Glass even if an adapter is used. 3D Gaussian splatting is a new scanning method that can reproduce photorealistic 3D scenes, and more and more scanning apps are becoming available for iOS. This app reads an exported file (.ply .splat) from a scanning app, displays it in 3D on Looking Glass connected to a USB-C equipped iPhone/iPad, and allows viewpoint control by touching the screen of the connected iPhone/iPad. The focus point and parallax can be adjusted with the on-screen slider. Please understand that due to the memory limitation of WKWebView used in the application, large 3D Gaussian Splatting and high resolution Looking Glass may not be displayed.
