Technical note

PDN to OBJ: what carries over and what does not

PDN is made of pixels, so the conversion works in two steps: the image is first traced into vector outlines, and those outlines are then extruded to the height you set. The result is real geometry rather than a picture wrapped in a 3D file. Outline tracing is the mode to use here, because it returns closed shapes, and only a closed shape has an area to lift. How good the result is depends almost entirely on the PDN going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

FAQ

PDN to OBJ Conversion

What are PDN files?

PDN is the native file format used by Paint.NET, a popular free image and photo editing software for Windows. A PDN file stores the entire project data for an image, including layers, layer properties, transparency, blending modes, text, and editing history. Unlike standard image formats like JPEG or PNG, which flatten an image into a single layer, PDN files preserve all editable elements, making them ideal for ongoing design work or complex image editing tasks.

What are OBJ files?

OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
