How to Use 3DGS Viewer for SHARP

Japanese Version

By using Apple’s “SHARP” (https://github.com/apple/ml-sharp), it is now possible to generate 3D Gaussian Splatting (.PLY) data from a single 2D photograph.

For users who find the official installation instructions and usage difficult to follow, i have prepared an easy-to-use “SHARP” installer for both Windows and Mac. Please feel free to use it if you wish.
Both the Windows and Mac versions can be installed with a single step. Simply drag and drop a folder containing the source images onto the desktop icon, and 3D Gaussian Splatting data will be generated automatically.

The 3D Gaussian Splatting (.PLY) files generated by “SHARP” are, of course, projected from the viewpoint where the original photograph was taken. Based on this, i have modified our previously released web application (which displays 3D Gaussian Splatting data in various 3D formats such as SBS, anaglyph, interlaced, etc.) and optimized it specifically for “SHARP”.

How to Use the Viewer
Drag and drop a 3D Gaussian Splatting (.PLY) file generated by “SHARP” onto the Viewer to display it in 3D.

・Mouse drag : Rotate the model freely
・Shift key + mouse drag : Translate (pan) the model
・Mouse wheel : Zoom in/out (technically adjusts the FOV)

S key : Change 3D display mode (SBS → LR / RL → Dubois Anaglyph → Color Anaglyph → Anaglyph → Interlaced → Half SBS → repeat)
X key : Swap left and right views
Left / Right arrow keys : Adjust stereo window
Up / Down arrow keys : Adjust depth perception (When adjusting depth, you may also need to adjust the stereo window)
0 (zero) key : Reset stereo window, depth, and zoom to default values
A key : Toggle auto-rotation ON / OFF
R key : Display REC button ON/OFF -> Press the displayed REC button to start recording. Press the STOP button to save.
H key : Show this HELP page
Enter key : Toggle full-screen / windowed mode
