Create a smooth, high-contrast grayscale DEPTH MAP for stereogram (SIRDS) generation based on this subject: a 3D volumetric sailboat/ship with billowing sails and a rounded hull. Ensure the sailboat looks fully three-dimensional and rounded, not flat. Key Composition & Framing: Isolate ONLY the sailboat, cleanly removing any background elements. Sizing & Scale: The object MUST occupy a maximum of 2/3 (66%) of the total canvas. Perfectly centered composition on a solid pure black background (RGB: 0,0,0). Depth & Luminance Mapping: Nearest / Most Prominent Elements (BRIGHTEST WHITE, #FFFFFF): The parts of the sails and hull physically closest to the viewer. Mid-Depth Elements (GRADUAL MID-GRAYS): The receding sides of the hull and sails, fading smoothly to dark grays. Furthest Background (PURE BLACK, #000000): The entire negative space surrounding the object. Technical Requirements for Stereograms: Render strictly as a continuous luminance depth gradient to give the sailboat a rounded, volumetric 3D shape. Smooth, soft transitions between depth layers. Absolutely NO colors, NO surface textures, NO lighting shadows, NO text, and NO fine surface details — ONLY pure height/depth encoding via grayscale brightness.
