Description
Key Features- Instant 2D to 3D Conversion: Seamlessly transforms flat PNG or JPG images into 3D STL mesh files using heightmap technology.
- Luminosity-Based Depth Mapping: Automatically interprets the brightness of pixels to determine 3D height—typically mapping black to the lowest point and white to the highest (or vice versa).
- Customizable Model Settings:
- Adjustable Height & Base: Users can define the thickness of the base and the maximum height of the 3D relief.
- Detail Control: Options to set the resolution (Low, Medium, High) to balance between file size and model precision.
- Smoothing Filter: Includes a feature to smooth out "spikes" caused by high-contrast pixels, ensuring a cleaner 3D print.
- Negative/Positive Inversion: Allows users to invert the height mapping, which is essential for creating "Lithophanes" (3D photos that reveal an image when backlit).
- Real-time 3D Preview: Provides a built-in viewer to inspect the generated 3D model before downloading the final STL file.
- Privacy & Speed: A browser-based or fast server-side tool that requires no software installation and processes files quickly.
