Curvy 3D
What it is
Curvy 3D is a Windows sketch-based sculpting program aimed at first-time 3D artists. Draw profiles and curves to form rounded or organic models, then refine surfaces with Inflate, Deflate, Pinch, Smooth, and Flatten warp brushes. Adaptive subdivision adds mesh detail where needed while limiting triangle counts. The program supports manual retopology, multiresolution sculpting, voxel sculpting, and painting of color, specular, and bump maps in 3D views or on 2D textures. Image Inflate converts silhouettes or greyscale images into 3D forms using heightmap, bubble, bevel, or extrude styles. Models export as OBJ for rendering or animation in software such as Blender. The maker also describes compatibility with Blender and Bryce, plus character imports from Poser or Daz. Aartform offers a free 30-day demo of Curvy 3D 5. Curvy 3D 5 is a one-time purchase with price varying by location and requires a DirectX 8.0-compatible 3D graphics card.
