Questions about license and conversion of rotation matrix

[Willy Tschager]

Hello everyone!

Are you allowed to create a software application that uses the LDR file format (the sets, not the parts) without asking or do I have to register my software somewhere? Because I am working on a game in which you build official and custom sets from the point of view of a minifig and it uses the LDR format to place all the bricks at the right position and players can import their own LDR files as long as they only use the parts that I have modeled for the game (it doesn't use any LDraw parts).

Short answer, yes. The licence stuff can be found here:

while LDraw.org policies and procedures are here:
