3D Modelling From a Sketch 215

hargettp writes "Happened to be skimming through the December BoingBoing and I noticed this link to research into 3D modelling by interpreting sketches. Basically, with a pen and tablet and a good Java applet, a user can start digitally modelling 3D structures about as easy as if they were molding clay with their bare hands. It was the demonstration video that made my jaw drop. Impressive!"

        Hmmm... There are several highly useful applications that sport exactly (well, close it it... they are more powerful than Teddy) that type of interface. They are the "secrets" of the 3D modelling world and once you use them you'll wish everything else worked like them.

        Mirai [izware.com] and Nendo [izware.com] are two commercial offerings and Wings 3D [wings3d.com] is a free modeling app that has a similar interface. Dispite all the Maya press, Mirai was used for some critical parts of LOTR.

        Izware (aka Winged Edge Technologies; aka Nichimen; aka Symbolics; aka ...) is the company that makes Mirai and Nendo. They have always been a strange company with very poor marketing and management skills so not many people know how great their stuff is. The company is always in a bizarre state of flux. For instance right now their main page says "We'll be right back" with no other links at all (it's been like this for ages; more than a year).

        Wings 3D fits between Nendo and Mirai. It's better than Nendo but doesn't offer all that Mirai does. However, it's free and open-source.

        The key to the useful UI is the context sensitive menus. All complex applications should work this way because it narrows down the possible actions to what you're working on. Instead of having hundreds or thousands of menus and buttons to push (*cough* 3DSMAX *cough*), you just have simple context menus based on what you have selected. It's a superb interface for managing complexity.

        Plus the help system is built right into the interface.
        • Oh yes, I am aware of the Nichimen products. I agree they have the style of interface I am talking about. Personally I have not used it, only seen it being used, but it just looks right to me, and the users have told me that it works and they love the larger visible area.

          Too bad they seem to be a niche market. Even Blender is better-known than their stuff.

        There's one catch - "doing what you want" is not always the easiest, nor the fastest way to do something. For example, what if, instead of just drawing a line, I want to draw a straight line. Suddenly, I need some kind of function that will constrain the movement along one axis. The alternative is to spend oodles of time trying to tweak a line until it's straight enough. What if I want to start out with a geographic primitive? Am I supposed to build one from scratch? Once I have that, what if I need to scale a part of it? Should that be done manually? Let's say I'd like to duplicate it and the flip it across an axis (often used for creating identical left/right portions of object)? Do I spend gobs of time doing this manually?

        Tools have their place- and often, if used correctly, they are there to help us produce superior results, and save significant amounts of time in the process. Just like an empty window, they aren't a substitute for talent and artistic skill, but they can sure provide ways to automate the purely tedious aspects of 3D modeling.

    I was researching 3D home design tools for my dad and came across a neat too called SketchUp 3D [sketchup.com] that sounds similar.
    SketchUp has a unique interface that allows 3D forms to be created, viewed and modified quickly and easily. The core of its simplicity is an interface that allows you simply to draw the edges of the desired model in 3D space, just as they would using a pencil and paper. Intelligent inferencing capabilities automatically determine the nature of the lines and "fill" shapes to create 3D geometry. SketchUp is used by all kinds of designers in many different industries. It is quick to learn, fast to use and hard to forget.
    • Actually SketchUp is very cool, plus they have a demo that lets you do everything you want for 6 hours of program-run time.

      Very simple to use, and they've thought of everything to make it simpler. Draw a line, and then click near the middle, it'll assume you want to find the center point (but you don't have to).
      It's really slick in realtime shading & rendering too.

      Wish I had the $$ to buy it, just 'cause it's fun.

      It's not true 3d though - they assume all the points drawn lie on a unit sphere, and project them onto that. However this is good enough to provide panoramic views from building sketches, for example.

    • Not really. Sketchup still relies on traditional polygonyl modelling techniques to create the models. SketchUps strength lies in its ability to render images that look like someone sketched the illustration but all the scale, shape and lighting are realistic. It's a very cool, though frustrating in some ways, program that does a good job of creating acrhitectural sketches, that can be updated easily and in real-time, from acrhitectural blueprints for client review.

However, most Sketchup functionality already exists in formZ. SketchUp just makes sketching (1) fun, (2) easy, and (3) look like pencil sketch lines or cartoon lines.

    Gamers out there might remember a game that game out about a year ago on the PS2 called Magic Pengel. It reminds me quite a bit of this project.

    In this game, you used a variety of different brushes to draw a monster. You had different options, such as picking a "head" brush to signify the object you were drawing was part of the monsters head, etc...but, for the most part, the game just saw the lines you were drawing. The AMAZING part of this game was that it would take your 2d sketch and, for the most part, flesh it out in 3d. Not only that, it would also fully animate the model through a built in algorithm.

    The impressive part was how well this worked. Not only did it do what it was supposed to do but, in most cases, it actually realistically animated the monster. It's a little cutesy, but you guys who are into this kind of thing should check it out!

    I downloaded SmoothTeddy when I first saw it on boingboing and have been playing with it a little. It's nice being able to create 3D images so flexibly, but there are bugs in the system. The interface has many elements of gestures (delete a shape by drawing a line from it to a trashcan, cut it apart by drawing a line across it, mirror it by drawing a line from a shape off into the air). However it's written in Java and it shows. It's more of a technology demo than something that can be used for real work at the moment. The program's only export format is to Alice, a combination 3D modelling/programming system (well... that's technically true at least, heh). The guy's page said that there's a commercial product in Japan that uses the Teddy technology, but that it's Japanese-only.

    Ignoring the bugs (many of which cause the program to freeze if an incorrect stroke is drawn), there are some cool elements to this. Most things you can draw end up looking almost exactly like a big pillow. You can draw objects on the pillow that intersect it and then adjust their location on the pillow's surface. When it gets where you want it you can "merge" it with the pillow. The program tries to create smooth meshes wherever it can, and making sharp corners is almost impossible without creative use of the cutting tool.

    Verdict: fun to play with if you have a good tolerance for bugs and don't mind that you won't be able to easily get your work into another program.
