Meshly is an intuitive low-poly mesh modeling application in VR. It is developed in response to the steep learning curve of 3D modeling software. Its goal is to be adopted by designers in their workflow as well as hobbyists without training in 3D modeling. The motivation of the project stems from the need for intuitive, freeform 3D modeling methods and the steep learning curve of professional mesh modeling software.

The interaction design is inspired by the small scale sculpting process where one holds and rotates the object in their non-dominant hand and uses their dominant hand to sculpt. In Meshly's modeling environment, the user could use the left controller as their “hand” that holds and orients the object. The right controller is then a metaphor for the “tool” that manipulates the object, much like a chisel or any other sculpting tool. To stay true to the simplicity of this paradigm and achieve more from less, the player movement is confined and direct controller collision replaces the common raycast pointer model.

There are 3 modes of interacting with the mesh; first is the create mode, where the user can create vertices, highlight and select, and make triangle faces through clockwise selection of 3 vertices. The user is also able to delete vertices, which will in turn delete triangle faces related to those vertices.

The second mode is sculpt mode, which could be toggled from the radial menu via the left controller thumbstick. It allows for selecting and moving vertices. In future iterations, more ways of sculpting the mesh could be added, such as attractor point deformation.

The third mode is color mode, where the user could color the vertices. Drag the Hue Ring selector and simply touch the Value triangle to finish color selection. The user is able to achieve a blended look or a discrete look depending on the number of vertices having the same color.

Aside from the menu, the left controller rotates and moves the entire mesh by pressing its index button.

Finally, there is also a simple file IO functionality with the left controller. The Y button imports an OBJ file from a specified path, while the X button exports the current mesh to the same path. The application runs via Oculus Link so the path is on the computer, but could be changed to an on device location if deployed as a standalone app.
