CopperLicht

? [...] CopperLicht is a 3D engine as well. It is an abstraction layer above this simple drawing API and makes it much easier to create 3D Applications: Instead of writing hundreds of lines of code to draw a few triangles to form a 3d world with WebGL, you can simply start up CopperLicht to do all this for you with one single line of code.?

  
Q1

Ambiera is well-known for irrEdit a level editor for irrLicht engine. Why are you developing tools for other engines such as Flash and WebGL?

A1

Ambiera's goal has always been to develop tools to help game developers creating games. That's also why Ambiera is developing irrKlang, the 3d audio library, for example. There are many game developer currently switching from old-school application development to web development, and we want to support them as well with our tools like CopperCube for 3D graphics in Flash or CopperLicht for WebGL.

  
Q2Flash 3D engines such as CopperCube have made huge improvements at the beginning, but it seems that they are still limited especially for 
displaying large scenes. Do you think that Flash 3D engines will be able to handle more complex scenes in a near future? What is your opinion about that?
A2

Yes, that's true. The big problem here is that one is quite a bit limited by the Flash platform: Obviously it was never designed to do
realtime 3d graphics, and all 3D engines for Flash such as CopperCube are hitting the wall. There are simply limits, and for 3D in Flash, those limits are reached very easily. 
Should Adobe extend their Flash API, and make real hardware accelerated 3D drawing functionality with Z-Buffer, Shaders and more available, this could change the game again, of course.

  
Q3CupperCube can generate interactions without any knowledge of Action Script, how far can people go without coding?
A3

The idea was to make it possible to create very simple scenes without the need to know anything about programming. For example you can create a 3D scene in CopperCube and make it possible to walk around in it. You can define simple actions like opening doors, moving objects, playing sounds and music, opening websites etc, triggered by different events. For example when the user walks near a specific object or clicks on something. It's all still very simple, but with a bit of creativity, you can create nice 3d scenes. By the way, all these events and actions are working in CopperLicht, the WebGL engine as well.

  
Q4The demos of webGL on your website look very promising ! It seems that webGL is much more ready to handle 3D contents than Flash. Do you think that Flash will be less and less used as webGL will begining to be available on browsers?
A4

Thanks! I was surprised myself how fast WebGL and especially JavaScript is, after I created the first tests with it. The Quake 3 Level rendered in realtime by CopperLicht for example speaks volumes: I guess there will be a lot of WebGL games created in pure JavaScript in the near future. And yes, I think needing a plugin for doing 3d graphics in the web won't work for very long. Plugins have a big disadvantage: They're plugins. You can simply omit them.

  
Q5webGL is a kind of binding of OpenGL for JavaScript. What is the role of CopperLicht ?
A5

webGL and OpenGL is, like for example Direct3D as well, only a drawing API. It is very primitive and it takes a bit of efford to write something complicated like a whole 3D game with it. That's why there are 3D rendering engines, like Irrlicht for example. And CopperLicht is a 3D engine as well. It is an abstraction layer above this simple drawing API and makes it much easier to create 3D Applications: Instead of writing hundreds of lines of code to draw a few triangles to form a 3d world with WebGL, you can simply start up CopperLicht to do all this for you with one single line of code.

  
Q6Actually CopperLicht and CopperCube UI looks more or less the same, do you plan to unify them so that people can deploy their 3D content "everywhere" (.exe, webGL, flash3D) ?
A6Actually, CopperLicht doesn't have any UI, it is just some code, the 3d engine. CopperCube is a 3D editor, and yes, it already is unified: It can publish to .exe, Flash 3d and now even WebGL using CopperLicht as rendering backend.
  
Q7About WebGL, it seems that Javascript must handle a lot of thing : parsing 3D models, interactions, collision, animations. Do you think that script language are enought fast for creating games?
A7I think it can do it, yes. The next release of CopperLicht will include a complete collision and response system, it is already partially
implemented in the current version. So with the next release, you will be able to run around in the 3d worlds and interact with items in there.
  
A8CopperLicht introduces a new compress file format, what is the benefit ?
Q8For CopperLicht, the whole 3d scene is compiled into one small binary file, the .ccbjs file (created by CopperCube). Since WebGL is web based and to draw the 3d world it needs to be downloaded first by the web browser, it is better if the data to download is smaller. This reduces the bandwith needed by the users and increases the speed in which the game loads.
  
 A9 For developer that want to create small games with CopperLicht which workflow do you suggest ? Can they create contents comparable as the one created with Unity3D or Virtools?
Q9Unfortunately I never used one of these tools, but I heard good things about them. The workflow for CopperLicht goes like this: Create your 3D objects in your favourite 3D modeller and import them into CopperCube, the 3d editor supports about 17 3D file formats. From there, you can edit, adapt and publish your scene with one click as interactive 3d WebGL program already. If you want to go on and create a real 3d game, you can then use CopperLicht to write your game based on this. Of course, you can do this also without the 3d editor CopperCube, but I guess this is the simplest way.
  
A10What are the next milestones in CopperLicht developpement?
Q10The next version of CopperLicht will include a complete collision and response system, to make it possible to walk or fly around 3d scenes without moving through walls and to interact with 3d objects. It will for example also be possible to walk up stairs etc, so it's a basic physics engine. But also character animation and a more extensible material system is planned, so there is a lot of good stuff to come.
