Rosholt Hornet LEGO Mosaic

May 8th, 2010

After a long break from building, I recently worked with students from Rosholt Elementary School to build a LEGO mosaic of their school mascot – a hornet.  Shown below is the completed project, which is about 3 feet wide by 4 feet tall.

Anti Aliasing with LEGO – Part 2

May 5th, 2010

In Part 1 of this series, I provided some simple examples of Anti-Aliasing (AA) with LEGO.  Today I will look at how the proper shade for each brick can be determined, for both standard and AA mosaics.  I will use the letter ‘A’ mosaic to demonstrate these processes.

In the image above, the red outline is the shape of the letter ‘A’ to be built as a LEGO mosaic.  The first step is to superimpose the outline over a grid of the desired size.  The smaller the pitch on the grid, the more accurately the ‘A’ can be represented, but the more bricks and effort it will take to complete the project.  For this example the ‘A’ will be positioned inside a 9 high by 11 wide grid.

Anti Aliasing With LEGO – Part 1

May 3rd, 2010

All my previous LEGO Mosaics fit neatly into two categories. First, there is the photo realistic type like the mosaics of my older kids, or my younger kids. Second, there is the solid area type like the Danny Phantom mosaic, or Starbucks logo mosaic.

Starting today, there is another category, which is solid area, anti-aliased mosaics.

In real life I am a business software developer. However, for fun I’ve recently started playing around with iPhone development. This hobby has introduced me to the concept of anti-aliased graphics. Generally speaking, anti-aliasing (AA) is the use of lighter (or darker) colors at region transitions to smooth out jagged transitions. LEGO bricks are a great way to demonstrate this technique.

Shown above are a couple LEGO mosaic examples with and without AA.  Hopefully the middle blue line seems less jaggedy and the right green circle and letter ‘A’ also appear smoother than those to the left.  I’ve purposely shown these images small, because in order for the advantage of AA to be realized visual blending of the pixels must occur.
