	Brickfest 2001 :: LDraw.org :: The Central Site for the LDraw Family of LEGO® CAD Software
		We presented an LDraw demonstration entitled "LDraw: Virtual bricks on your computer" on Saturday the 14th.
		The demonstration consisted of a general history of LDraw, an introduction to the various facets of creating LEGO models with the software.
		LDraw is a completely unofficial, community run free CAD system which represents official parts produced by the LEGO company.

		LDraw is the name for James Jessiman's CAD system for modelling LEGO creations.
		Today, LDraw is not just an application but a system, with the LDraw file format being used by many third party editors (such as LeoCAD and MLCad), model viewers, converters and renderers.
		It is also possible, via the LDraw website, to track the progress of new parts as they are submitted to the community and approved.

	LDraw Colors
		The good news is that LDraw does support dithering of the 16 colors, so it's possible to get a pretty close match to real LEGO.
		I used LDraw to generate the images, and wrote a little utility program to correct the color values.
		Some of the LDraw color examples (the last column) may not display correctly, because your browser may be forcing the colors into a "web-safe" value.

	LDraw - Brickwiki (Site not responding. Last check: )
		LDraw is an application written by the late James Jessiman for DOS.
		The LDraw format divides a model into steps so that the building instructions can be incorporated into the design, and also allows for steps that rotate the camera and even (primitively) move parts around.
		There are many programs written to handle the LDraw file format for a variety of platforms.

	Creating LDraw Parts: LDraw Primitives Reference
		To avoid matrix arithmetic problems in some renderers, the third dimension ({y} in the default orientation) of two-dimensional primitives should be given a scaling factor of 1.
		LDraw circles are normally formed of 16-sided polygons (hexdecagons) - the regular resolution.
		An additional primitive (studline.dat) is used to substitute a single line for studs by the super fast-draw mode of LDraw.

		The LDraw Webring is a ring created for users of the LDraw Lego-related cad program who display their creations on their site.

	Brickfilms.com :: View topic - LDraw to .ASE or another format
		I think this is caused due to the fact that the LDraw parts library is not totally compliant for back face culling (the winding of the faces is mixed between clock wise and counter clock wise in the same geometry).
		The method how ldraw handles primitive inclusion introduces a lot of artifacts of this kind.
		The LDraw guys are aware of this and there is a BFC extension to the original format but not all parts esp. unofficial ones are compliant to this.

		Converts standard LDraw files into a format that POV-Ray can use.

	Importing and Rendering LEGO 3D Data
		Nonetheless, it is ideally targeted at the existing community of LDraw program users to show how their models can be rendered and animated in a program other than POV-RAY (which is pretty well the standard used throughout this community).
		First, you need to understand that the LDraw program is at the center of the 3D LEGO parts modeling universe.
		We found that this produces the most acceptable conversions from LDraw format to the format Okino customers need (Lightwave will be an ideal file format); it converts the data into 3d model geometry, assigns materials (with color, transparency and reflectivity), and sets up the lights.

		LDraw is a DOS program that allows you to draw LEGO models, create building instructions for them, etc. - A LEGO-style Computer Aided Design system.
		You can edit LDraw files with the accompanying LEdit program or with your favourite text editor (the latter is said to be very hard, but I do it anyway.
		There are two tools for converting LDraw models to the format of the ray-tracer POV-Ray.

	Creating LDraw Parts: LDraw file format
		LDraw Model files carry either the extension LDR (default) or DAT.
		If the first line in a file has line-type 0, the remainder of that line will be considered the title for the file (at least for parts files).
		This is also like the Step command, but it does not cause LDraw to pause, and it is not affected by the

		LDraw is a piece of computer software written by James Jessiman that can be used to create computerized models or building instructions for use with Lego - the highly popular Danish plastic building bricks.
		LDraw was originally written as a DOS command line program, that is, it has no user interface other than series' of typed commands.
		LDraw and a variety of related software including the MLCad and LeoCad Windows interfaces can be downloaded for free at LDraw's website.

	L3P by Lars C. Hassing
		However, I was disappointed that my ray-traced model had "holes" in it, because some parts were not yet in LGEO-format (it was 3063 Brick 2 x 2 Corner Round, 7 Tyre Single Smooth and 3137 Brick 2 x 2 with Wheels Holder, which all have been added since then).
		LDraw searches for DAT files in four places: in the current directory, in the P directory, in the PARTS directory and finally in the MODELS directory.
		The LDraw colors are 0-15, 32-47, 256-511 (and of course 16 and 24).

		For more information about LDraw, including obtaining the LDraw parts library, instructions, and applications for viewing, editing, converting, and rendering these files, see www.ldraw.org.
		"Official" LDraw parts are approved of by an LDraw committee and meet their standards for proper LEGO parts and the complete library package can be downloaded from www.ldraw.org.
		"Unofficial" parts have not been approved by the LDraw committee, but some are available from www.ldraw.org, and some are available all over the web, in nooks and crannies, wherever you can find them.

	LDraw Apocrypha FAQ
		Using the same.dat format as official LDraw files, these pieces can be incorporated into one's existing parts library, allowing the user to create models with a range of unofficial parts.
		Another issue of compatibility pertains to the positioning of the part relative to the x-y-z rotational axis; the default for official LDraw parts is to position the topmost surface of the part at y=0.
		Rest assured that even the clone parts that are basically identical to official LDraw elements were written from scratch, rather than simply renaming existing parts, and each clone part has small but real differences from its official counterpart in order to demonstrate that the clone was written from scratch.

	CSSoh's Lego Pneumatics LDraw Pneumatics 28 May 2003
		When I first started to document my pneumatics models with LDraw, there were no official pneumatics parts in the library.
		In time, realistic pneumatics parts were added to the LDraw library due to the interest in building pneumatics models and the diligent work of the LDraw parts originators like Marc Klein and others..
		Building instructions generally used the pictures generated by LDraw or MLCad with the STEP meta-command that outputs a picture at the end of each instruction step.

		So I decided to make an LDraw version, somewhat of overkill, because FwA is all 2-D and LDraw is great for 3-D work.

		If the length of the curve LDraw mode comes up with is too short or too long compared with what you originally wanted, you can try to increase this number to overcome the problem.

		Causes the image to be centered in the middle of the window, rather than the ldraw default of 2/3-of-the-way-down.
		For whatever reason, LDRAW sets the default origin to be 2/3 of the way down the screen; LDLITE keeps this tradition.
		Similar to the way LDRAW works, the name of the dat file is truncated and digits are appended, with less of the dat file name being used as the number increases.
