3D OBJECT VOXELIZER

Program Overview

This program converts 3D models in OBJ format into a voxelized representation using an octree-based algorithm. It is able to:

• Read 3D models from OBJ files
• Voxelize them using determined tree depths
• Visualize the results with an interactive 3D viewer
• Export the voxelized data

The program is built in Java with a GUI for visualization and supports concurrent processing for efficient voxelization.

Requirements

Java Runtime Environment (JRE) 8 or higher

Compilation

Not needed because the program is already compiled and ready to run. The .class files are located in the bin/ folder.

How to Run

1. Open Command Prompt/Terminal and navigate to the project directory:

   cd Tucil2_13524006

2. Run the program:

   java -cp bin Main

3. Follow the instructions:

   • Enter the path to your OBJ file
   • Enter the maximum tree depth (use a positive integer)

How to Use

Input

1. OBJ file path: Provide the full path to your 3D model file
2. Maximum depth: Specify the maximum depth for the octree voxelization
   • Higher depth = finer voxelization (slower)
   • Lower depth = coarser voxelization (faster)
   • Typical range: 3-10

Output

After processing, the program provides you with informations about:

• number of voxels
• number of vertices
• number of faces
• number of nodes created per depth
• number of nodes unexplored per depth
• octree depth
• processing time
• path to the result .obj file

then opens an interactive viewer where you can:

• Rotate: Click and drag
• Zoom: Use the scroll wheel to zoom in/out
