sculpt-rs

A real-time 3D sculpting tool written in Rust, with dynamic topology and a GPU renderer. Built for a pen and a touch screen as much as for a mouse.

• Dynamic topology. Detail appears and disappears under the brush by splitting and collapsing edges, so the starting resolution does not matter.
• Sixteen brushes. Draw, Clay, Flatten, Smooth, Pinch, Crease, Inflate, Move, Drag, Twist, Scale, Paint, Smudge, Blur, Fill and Mask, each keeping its own radius, strength and options.
• Falloffs and alphas. Five falloff curves, procedurally generated alphas, and any image you load.
• Symmetry, masking and painting. Mirror across any axis, a protection mask with blur and sharpen, and painted colour, roughness and metalness.
• Voxel sculpting. A voxel field behind the brush makes the cost of a stroke independent of the polygon count. Toggle with V.
• Files. OBJ, PLY and STL in and out, and a compressed scene format with per-channel blocks.
• The interface. Docked panels that tear out, a radial menu, and gesture support for pen, touch and mouse.
