Curvy 3D vs Re:Form

Curvy 3D is a Windows sketch-based sculpting program aimed at first-time 3D artists. Users draw profiles and curves to make rounded or organic forms, then refine surfaces with Inflate, Deflate, Pinch, Smooth and Flatten warp brushes. Adaptive subdivision adds mesh detail where needed while controlling triangle counts. The program supports manual retopology, multiresolution sculpting and voxel sculpting. Texture tools paint color, specular and bump maps in 3D views or on 2D textures. Image Inflate converts silhouettes or greyscale images into 3D models using heightmap, bubble, bevel or extrude styles. Models export as OBJ for rendering or animation in software such as Blender. The maker also describes use with Blender or Bryce and importing characters from Poser or Daz. Curvy 3D 5 is listed for Microsoft Windows and requires a DirectX 8.0-compatible 3D graphics card. Aartform offers a free 30-day demo; the Curvy 3D 5 plan is a one-time purchase with price varying by location. Aartform describes itself as an independent London game development studio founded in 2003, and directs questions to its forum.

Re:Form is a browser-based 3D sculpting studio that uses WebGPU, with macOS also listed as a platform. It offers 34 brushes and tools, including blockout, GPU subdivision, layers, symmetry, masking, vertex paint, renders, and turntables, plus pen and touch support. It runs in desktop Chrome, Edge, Firefox, and Safari 26 when WebGPU is available; there is no download or installation, and updates arrive with the web page. Projects autosave ten dated browser snapshots, while saved projects retain layers, paint, reference images, and viewport settings with the account. OBJ import and export are available on every plan; Pro adds STL, GLB, and FBX. Free supports renders up to 2048 pixels and five share links at a time. Pro adds 4096-pixel and 8K rendering, unlimited links with a public 3D viewer, and a commercial license. Free is limited to personal, non-commercial use. The product is v0.8.6 Alpha. Free is free; Pro is $9.99 a month, billed monthly.
