Create a smooth, high-contrast grayscale DEPTH MAP for stereogram (SIRDS) generation based on this subject: a graceful mermaid with a flowing tail and long flowing hair. Anatomy & Silhouette Specifics (IMPORTANT): - Smooth, flawless, perfectly rounded anatomical transition from waist to hips, buttocks, and down into the mermaid tail. - Clean, continuous, rounded curved silhouette line from waist to hip to tail with NO curls, NO hair strands, and NO clutter overlapping the buttocks or hip area. - Long hair flows cleanly behind the shoulders and back, leaving the hips and buttocks completely clear and clearly defined. Volumetric 3D Rule: - The mermaid must look three-dimensional and rounded, NOT flat. - Render gentle, soft rounded 3D volume across the whole silhouette, brightest along the central raised mass and smoothly darkening toward the sides to model a rounded body. - The brightest core must be a soft glowing gradient (a rounded 3D bulge), NOT a flat white fill; keep a smoky, foggy internal falloff for maximum roundness. Depth Layering & Occlusion Separation: - Strictly prevent overlapping elements from fusing into a single flat mass: * Foreground focal elements (chest, near shoulder, face) must be clearly separated in brightness from adjacent overlapping framing elements (hair, tail folds). * Layer Hierarchy: Overlapping or secondary surrounding elements (hair, back arm) must be rendered a half-tone darker than the main prominent foreground structure to preserve clear spatial separation. * Distant / Receding Limbs & Details: Any background limbs, distant tail fins, or structures positioned further away from the viewer MUST be distinctly darker (lower luminance) than the main torso/body. Contour & Edge Requirements: - The mermaid's OUTER silhouette must have a clearly READABLE edge against the solid black background — defined, but NOT razor-sharp. - Let the volume gently round off near the border, so the edge reads clearly while the body still looks rounded. Key Composition & Framing: - Isolate ONLY the mermaid silhouette on a solid pure black background (RGB: 0,0,0). - Sizing & Scale: The subject MUST occupy a maximum of 2/3 (66%) of the total canvas both horizontally and vertically. Leave generous, wide empty negative space all around. - Perfectly centered composition. Depth & Luminance Mapping: - Use the FULL tonal range from pure black to pure white for maximum depth separation. - Nearest Elements (BRIGHTEST WHITE, #FFFFFF): Parts physically closest to the viewer (chest, closest hip/torso plane). - Mid-Depth Elements (GRADUAL MID-GRAYS): Receding sides, mid-torso, front of the tail fading smoothly to dark grays. - Distant Parts (DEEPER DARK GRAYS): Furthest tail tip, back arm, distant hair layers. - Furthest Background (PURE BLACK, #000000): The entire negative space surrounding the object. Technical Requirements for Stereograms: - Render strictly as a continuous, banding-free luminance depth gradient that gives the object a rounded, volumetric 3D shape. - Smooth, soft transitions between depth layers with NO visible steps, bands or posterization. - Absolutely NO colors, NO surface textures, NO lighting shadows, NO cast shadows, NO glow/halo around the object, NO text, and NO fine surface details — ONLY pure height/depth encoding via grayscale brightness.
