Image PNG to OBJ Converter

Purpose-built conversion tool that takes PNG textures and generates usable 3D geometry in the OBJ format. It supports two core generation methods: depth-based extrusion, where pixel brightness maps to a height field, and contour-based extrusion, which emphasizes edges to form surface topology. The system outputs OBJ, MTL, and optional texture files, enabling straightforward import into common 3D pipelines. The underlying logic computes UV coordinates from image space, applies optional texture baking, and can target a desired polygon density to balance detail with performance. The tool is beneficial to artists, game developers, and design engineers who need a fast, texture-driven starting mesh or a test asset for visualization and iteration. Unique value lies in its dual-mode geometry generation, batch processing capability, and automatic maintenance of texture alignment across outputs. Use cases include turning textures into base characters or props, generating test assets for engine testing, and producing quick prototypes for product visualization.
