PNG 2D to 3D OBJ, How Does It Work?

Standard Mode (Heightmap)

In Standard mode our tool examines your 2D PNG image and based on the luminosity of each pixel, will create a corresponding "3D" pixel where the height of the pixel is determined by the pixel luminosity. A black pixel in your PNG will have a height of 0mm and not be included in the final 3D generated model, however a white pixel will have a height that you specify once your image is uploaded. The tool has a Invert Output option if you wish to reverse the model height calculations in your Wavefront OBJ file. When this option is selected a white pixel will have a height of 0mm and a black pixel will have the height you have specified. This mode is ideal for the conversion of detailed heightmap images into 3D OBJ models.

Extrude Mode

In Extrude mode our PNG tool behaves in a similar way to Standard mode except the tool attempts to find simple shapes in your image and it performs an Extrude operation on any shape found. The height of the extruded shape is again based on the pixel luminosity. This mode is ideal for simple images such as logos and other simple shapes such as coins (see our Coin examples in the library tab). We also have another version of this tool aimed at extruding images to color 3D models, this is only available to 3D file formats that support color such as 3MF.
