SPSculpt

SPSculpt is a 3D sculpting desktop application written in C++.

How to Run

1. Download the SPSculpt_vX.X.X.zip archive from Releases.
2. Extract the contents to any convenient folder on your computer.
3. Open the extracted folder and run SPSculpt.exe.

Relationship to SculptGL

SPSculpt is a native C++ port and optimization of SculptGL, the web-based sculpting application created by Stéphane Ginier.

What Remains from the Original SculptGL:

• Core Algorithms: The mathematical formulas for the original sculpting brushes (Clay, Flatten, Smooth, Crease, Pinch, Paint, Mask, Move, Drag, Inflate, Twist, Local Scale, and Standard Brush) and stroke interpolation.
• Mesh & Topology: Voxel remeshing (Marching Cubes-based surface reconstruction), dynamic subdivision, decimation, octree traversal, and quad-sphere generators.
• File Compatibility: Native support for reading/writing SculptGL Scene (.sgl) files.
• Shading Math: Ported GLSL equations for Matcap, PBR, and Curvature rendering.

What Was Replaced (C++ Native Version):

• Core Tech: 100% rewritten in C++20 (no JS/WebGL/WASM/Emscripten remaining).
• Window & Input: Managed natively via SDL2 instead of browser-based APIs.
• User Interface: Powered by Dear ImGui instead of the original lil-gui/HTML interface.
• Performance: Optimized with OpenMP multi-threading and asynchronous background workers.
