Legolizer; Custom Lego Objects

The legolizer software converts any triangular mesh, a 3D model, into a 3D Lego model.

The digital 3D Lego model can be used for 3D animation and/or stills or used to build a custom Lego sculpture with real Lego bricks.

If you want to build a Lego sculpture yourself the Lego sculpture need to be stiff and strong. The legolizer software is optimized for maximum strength; prefference for overlapping and staggering above stacking. Besided the 3D Lego model the legolizer generates a series of blueprints. Each layer is a seperate blueprint to make the manual build process as easy as possible.

A Porsche made of lego, by Lego Certified Professional R. Hoffmeister and A. Al-Rubaie from 1000steine.com. A basic, mono-coloured lego structure was made using the legolizer. René and his colleague used it as a basis and then fine-tuned it, added the patterns and colouring and, last but not least, built this impressive piece of lego art.

Blueprints

Once the complete 3D lego model has been generated, it's time to generate a blueprint for each vertical layer of lego bricks and start building the real lego object. If you want to use the 3D lego model for 3D this step is not neccessary.

Reproducing the blueprints on a one-on-one basis is not sufficient to build the real lego object.

The real object is not rigid enough to withstand gravity. For this project the lego bricks on the outside needed to be approxiamately 3 lego units thick.
For instance, to prevent the arms from falling down, more bricks are needed. The inside needed a internal structure as well to prevent the object from collapsing from under it's weight. During the building phase these additional lego bricks are applied.

To build a lego model, you can either use only lego bricks or a combination of lego bricks and lego plates.

Lego Bricks & Color

To reproduce the colors of the original 3D model you can use any color for the lego bricks. This approach works fine as long as the legolized object is virtual, meaning that it can be used for a 3D animation and/or 3D still.

Building a legolized 3D model as a real-life lego object may be a problem. lego bricks are available in a limited range of colors. A 1 x 1 lego brick is available in the following colors: white, bright red, bright blue, bright yellow, black, dark green, brick yellow, bright orange, medium blue, dark stone gray, reddish brown, medium stone gray, bright yellowish green, light purple, bright purple and medium azure. Depending on the lego brick type, there may be more or less colors available in the pick-a-brick lego store.

For a real-life lego model, the colors of the original 3D model must be converted to one of the available colors, which reduces the fidelity compared to original 3D models (see image above).
