CubicCraft: A Mesh Stylization Tool

Report Slides Demo Video Code

Haoda Li, Puyuan Yi, Victor Li, Zhen Jiang

In this project, we present a stylization tool to automatically manipulate 3D objects into a cubic style. Our tool provides a GPU implementation for Cubic Stylization [Liu and Jacobson 2019]1, while cubify the object while preserving the geometric details. With our tool, 3D artists can create Minecraft-styled objects with ease.

Install and Execute

The code should support all platforms other than Mac M1 chip.

git clone https://github.com/haoda-li/CubicCraft.git
cd CubicCraft

pip install -r requirements.txt
cd main

# If you have a Mac or your computer does not have a GPU
# change gui_taichi.py line 6 
# from ti.init(arch=ti.gpu)
# to ti.init(arch=ti.cpu)
python gui_taichi.py [PATH TO MESH FILE]

GUI Controls

• Use Preset Camera View to change to the axis-aligned camera view that you like. You can also press w, s, a, d, e, q to move the camera forward, back, left, right, head up, head down, accordingly. In addition, use the right mouse drag to change the camera's viewing angle.

• Press Enter deformation button and LEFT CLICK the mesh to add new handle points. You can use BACKSPACE on your keyboard to delete currently selected handle point (red) and use TAB to switch to another handle point. By default, one handle is added to the first vertex because cubic stylization needs at least one constraint.

• Use paused checkbox to run and pause cubic stylization optimization. If the mesh is too large for real-time optimization, then use Step button to manually run one iteration of the optimization.

• You can change the cubeness parameter to generate new mesh with different cubic-stylized extent.

• Rotate three axes to cubic stylize your mesh in different cube orientation.

• After adding at least two handle points, you can do experiments with as-rigid-as-possible deformation. Use keyboard UP, DOWN, LEFT, RIGHT, SHIFT, SPACE to move your selected handle point up, down, left, right, back, and forward according to the world coordinate. Use TAB to switch between handle points.

• Use Save mesh button to save your cubic-stylized mesh, the output mesh will be written to the same directory as the input mesh.
