4D Toys Version 1.2 / Update 5: Anti-Gravity, Export Mesh for 3D Printing, 4D Accelerometer

Wednesday, August 19th, 2020

Here is another 4D Toys Update (iOS) (Steam VR + Mouse & Keyboard).

It adds three buttons:

  • Export Mesh: Exports a 3D mesh of what is currently visible on screen.

    These meshes can then be 3D printed, etc… (Unfortunately 4D printing is not yet available in this universe :P).

    Find the meshes in your Documents folder. (On iOS you can access it by connecting your iDevice to your computer and using Finder).

    Note that Shapeways’ algorithm for filling the inside of meshes sadly fails on some of the coolest meshes like the Star Polychora from the last update, since they are filled with lots of polygons on the inside (btw it’s fun to poke your head inside these meshes in VR!).
  • Anti-Gravity: Creates an anti-gravity field that makes objects float. Besides the obvious coolness, this allows to see rotations that are unrestricted from the constraints of the collision with the ground.

  • 4D Accelerometer (iOS only): Swaps the forward/backward direction of the accelerometer with the 4th dimension.

    That is, tilting your device toward/away from you will result in a force along the 4th dimension instead.

A new page of shapes has been added, with one new level for each button. Visiting each of these levels unlocks the corresponding buttons. Also, all special buttons are now gathered into a new menu button. This lays the groundwork for easily adding new features in future updates!

Btw, the SIGGRAPH conference started and my talk on nD Rigid Body Dynamics is now online (I will post it publicly in a few weeks). The Q&A session is on Wed Aug 26 at 9:00AM PDT!
