Project should take an OBJ file (using pygame, pyopengl, or any other well supported library you may prefer) and convert it to an LDraw format, which is a fairly simple text based format. OBJ is a common format for 3d objects, but LDraw is less common. It's a text file format description of a LEGO model. The full specifications are here: [login to view URL] But in reality very little of the spec will be used for this. There will be the header, the lines for parts, and a "step" line for each "level" of the piece. A line for a piece will need just color information, location information and the piece (one of two possibilities). Other info (rotation and other transformations) won't be used. Essentially, the conversion should run the following operations on the OBJ file: Create an array imagining a set of smaller blocks ("plates"). The number of blocks in height is set via command args, and the width and depth of this array are then just as many as they need to be to cover the OBJ object (example below). The ratio for the plates is 0.4x1x1 (HxWxD). Looping through the array, find each block that intersects with the OBJ object. Keep those blocks and discard the rest, creating essentially an array of binary blocks ("does this block intersect or not?"). Either as a secondary loop, or during the initial one: check the color/texturemap of each area that's inside a given block. Average the color and find the nearest match to a list of "good" colors (standard RGB values) in a passed config file. Now we have an array of blocks with specified colors. Awesome. Nearly there. With the array, working from the lowest/bottom level, check each block with the level(s) above it. If there are three in a column that match color, flag the bottom of the three and remove two above it. Do this for each level (so one of these "three blocks" can start at any of the levels). Three LEGO "plates" stacked together make a "brick" (ratio 1.2x1x1 if useful) . At the end of each of these levels, add a "step" line to the LDraw file. Important note: While I envision this solution as basically "create a three dimensional array and loop through it", if you have a more clever way to solve this, as long as the output file is right, how to get there is not set. Example: The command line should then look somewhat like (may vary depending on how you read command args): > python [login to view URL] --file=[login to view URL] --colors=[login to view URL] --height=100 This would take my '[login to view URL]' file and map it to an array of blocks 100 high (making that array as wide and deep as needed) and colorizing the blocks to match that json file, saving it to a reasonable default like '[login to view URL]'. This process will have a couple of uses in the end, but the simplest, and easiest to visualize, is to convert an OBJ file into a set of Lego instructions. Three of the shorter "plates" of a Lego block can combine into one "brick", hence that secondary loop through the results. Moving them into a reduced color set allows us to make to available Lego blocks. The end file then becomes a set of Lego instructions to build the OBJ file at whatever height was specified. I have a .net version of this that completes step 1 (only) of this, making an array of blocks. It's not Python, and only does the beginning loop, but if helpful to visualize one solution to that part of things, it is available here: Attached: simple ldr sample file (final file format) sample obj file with texture mapping as example source files sample config file sample color file
