We have put together some sample images and their resulting STL output. When converting your own files you will have the option to submit your file after conversion, feel free to check this if you would like your file to be considered for inclusion on this page.
Here we have a simple swirl pattern demonstrating the ability to create fixed height 3D models based on simple black/white images. When constructing the 3D model our converter will apply a height of 10mm to the geometry where it finds a white pixel and 0mm to any black pixels.
This is a more complex swirl pattern demonstrating the ability to create variable height 3D models based on grey-scale images. When constructing the 3D model the converter will apply a height of 10mm to the geometry where it finds a white pixel and 0mm to any black pixels. All shades in-between will be represented proportionately in the final 3D model.
Here we use the same image and select the "Invert Output" checkbox option. This reverses the resulting geometry:
Here we are using the Extrude (Color) mode to convert a color logo into a 3D model ready for editing within Blender. The Extrude (Color) is only available to 3D file formats that support color such as DAE, 3MF, PLY, WRL and X3D:
