Cracked wooden heart with dark patina and fissured surface texture.

3D rendered wooden heart form exhibits systematic surface fracturing with linear cracks distributed across convex lobes. Material demonstrates weathered mahogany coloration transitioning from deep brown to burnt sienna with lighter oxidation marks. Surface topology shows precise geometric segmentation; multiple fissures create polygonal tessellation patterns. Lighting emphasizes dimensional depth through graduated shadow mapping across curved surfaces, revealing subsurface texture variation consistent with aged timber deterioration.
