Design 3D sculptures and paint models, with Sculptris
Sculptris is a free (with regristration) program that will help you create 3D sculptures. Sculptris is small and focused at its main task, which is sculpting and painting models.
Features: Draw creases or folds. Inverse will make a ridge. * Rotate brush region. Click and drag outside the circle. * Scale brush region horizontally and vertically. * Draw/lift smooth features on the surface. Inverse will push down or draw holes. * Push surface towards the local plane. Inverse will deform and amplify details.
Move a region freely in the image plane. No inverse. * Expand in the direction of the surface. Inverse will deflate/contract. * Squish the surface towards cursor, tightening creases and corners. Inverse will do the opposite. * Soften features to make an area smoother and rounder. No inverse. * Remove triangles to decrease mesh density in the area touched.
