What Curvy 3D is
Curvy 3D is a Windows sketch-based sculpting program aimed at people making their first 3D art. Users draw profiles and curves to form rounded or organic models, then reshape surfaces with Inflate, Deflate, Pinch, Smooth, and Flatten warp brushes. Adaptive subdivision adds mesh detail during sculpting while keeping triangle counts down. The program also supports manual retopology, multiresolution sculpting, and voxel sculpting.
Users can 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 can be exported as OBJ for rendering or animation in other software such as Blender. The download page also describes using Curvy with Blender or Bryce and importing characters from Poser or Daz. Aartform offers a free 30-day demo of Curvy 3D 5. The program is listed for Microsoft Windows and requires a DirectX 8.0-compatible 3D graphics card; its listed one-time purchase price varies by location.
