ornate picture frame 3d model

Create a realistic 3D model of a traditional Dutch ripple picture frame. The frame is rectangular, mitred at the corners, with a deep carved profile about 70 mm wide and 40 mm deep. From the inner edge outward: a narrow rounded sight edge, a shallow hollow, then a dominant ripple moulding made of repeating rounded wave forms running continuously along each rail. The waves are smooth, organic, and hand-carved in character, with clear relief and soft transitions, not sharp or mechanical. Beyond the ripple is a small outer slope and a simple back edge with a shallow rebate. Surface should resemble gessoed and water-gilded wood with subtle irregularity and slightly burnished high points. No ornament, leaves, or Rococo decoration; emphasis on rhythmic ripple carving and believable historical proportions.
