Descriptions
Short (30 words)
Qwartz is a low-poly 3D modeler for iPad and Mac. Build game-ready meshes, paint pixel art directly on faces with no UV mapping, and export to glTF, OBJ, or STL.
Medium (100 words)
Qwartz is a native low-poly 3D modeler for iPad and Mac, built around a single differentiator: paint pixel art directly on mesh faces with no UV mapping. Per-face pixel grids size themselves to the geometry; move a vertex and the texture follows. Beyond pixel paint, Qwartz ships a complete modeling suite — seven primitives, full mesh editing (extrude, inset, loop cut, subdivide, slide), a UV editor with painting tools, a tile mode for level building, and export to glTF, OBJ, and STL. Apple Pencil drives tools, fingers drive the camera. One-time purchase. No subscription, no account.

Qwartz is a low-poly 3D modeler for iPad and Mac, published by Gargant — an independent software studio also responsible for Reflow (tablature & notation) and Pyxen (Python game maker). Qwartz is the studio's first 3D tool.
The defining feature is pixel paint on mesh faces. Tap a face and start drawing — the pixel grid sizes itself from the geometry, with no UV mapping, no atlas setup, and no external image editor. Edits to the mesh preserve the texture: move a vertex and the painted pixels resample with the new face shape. Pencil, eraser, fill, eyedropper, line, rectangle, and circle tools — the same pixel-art toolset users know from sprite editors, applied to a polygon. No other app on iPad or Mac does this.
Beyond pixel paint, Qwartz is a complete low-poly modeler. Seven mesh primitives (cube, plane, cylinder, sphere, cone, torus, quad grid). Object, face, edge, and vertex selection modes. Extrude, inset, loop cut, subdivide, merge vertices, create face, slide, edge extrude, dissolve, flip normals. A transform gizmo with axis constraints and snap-to-grid. Edge and face loop selection on double-click. Full undo/redo for every operation.
For traditional texturing, a UV editor opens in a split view with manual vertex editing, marquee select, gizmo tools, and a full painting toolset on the texture itself. Live preview updates both panes simultaneously. Materials can be flat colors or PNG textures, with planar and box auto unwrap. A face uses either pixel paint or a material — never both — so the workflow stays unambiguous.
Tile mode lets users stamp tiles from a sheet PNG onto faces, with rotation and flip per stamp. Combined with the Quad Grid primitive (an instant floor) and edge extrusion, building a tiled level becomes a few minutes of work.
Qwartz exports to glTF 2.0 (binary .glb with embedded textures), OBJ + MTL + texture PNGs, and binary STL for 3D printing. It imports FBX and OBJ with materials, UVs, and textures (via ufbx). A turntable renderer can produce animated GIFs or MP4s for portfolios. The native .qwartz file format is a standard ZIP archive — open and inspectable, with backwards compatibility for legacy .bevel files.
Native Apple app throughout: SwiftUI shell, Metal renderer, AppKit on Mac, UIKit on iPad. Universal binary, Apple Silicon native. Apple Pencil drives every tool; fingers drive the camera. One-time purchase, no subscription, no account, no tracking. Free trial includes the full editor with no time limit; an evaluation watermark on exports is removed by purchase.
Key Features
- Pixel paint on 3D faces — paint pixel art directly on a mesh face with no UV mapping. Per-face pixel grids sized automatically from geometry. Mesh edits preserve the painted texture.
- Mesh modeling — 7 primitives (cube, plane, cylinder, sphere, cone, torus, quad grid), object/face/edge/vertex selection, extrude, inset, loop cut, subdivide, merge vertices, create face, slide, edge extrude, dissolve, flip normals.
- Transform gizmo — translate, rotate, scale with axis constraints. Snap to grid with configurable increments. Vertex slide and edge slide along connected geometry.
- UV editor — 2D split view with vertex editing, marquee select, gizmo, and a full pixel-art toolset (pencil, eraser, fill, line, rectangle, circle). Live preview in both 2D and 3D simultaneously.
- Materials — flat color materials with optional PNG textures. Auto UV unwrap (planar and box projection).
- Tile mode — stamp tiles from a sheet PNG onto faces with rotation and flip; quad-grid primitive as an instant level base.
- Apple Pencil + touch (iPad) — Pencil drives tools (select, paint, drag, stamp), finger drives the camera (orbit, pan, zoom). Use both hands at once.
- Import — FBX and OBJ with materials, UVs, and textures (via ufbx).
- Export — glTF 2.0 (.glb) with embedded textures, OBJ + MTL + PNGs, binary STL for 3D printing. Turntable render to GIF or MP4.
- File format — .qwartz is a ZIP archive (scene.json + tile sheet PNGs). Open and inspectable. Backwards-compatible with legacy .bevel files.
- Native — SwiftUI shell, Metal renderer, AppKit on Mac, UIKit on iPad. Universal binary, Apple Silicon native. Works fully offline.
- Privacy — no account, no analytics, no telemetry, no third-party tracking.
History
- Late 2025 Project starts as 'Bevel 3D' — a low-poly 3D modeler experiment alongside Pyxen and Reflow.
- Early 2026 Pixel paint mode designed and shipped — painting pixel art directly on 3D faces with no UV mapping. The core differentiator emerges.
- Q2 2026 Renamed to Qwartz. Tile mode, UV editor, material system, glTF/OBJ/STL export, FBX import all complete.
- v26.0 (2026) First public release on iPad and Mac App Store.
