No collaboration without integration

collaboration9.pngFirst we had e-mails. Our paper mails, artistic handwriting and other personalized communication was gone.Then we had websites. Our e-mails were reliefed and we could share information with everyone.Then we had blogs. Our websites were updated less frequently and all structured information was gone.Then we had rss feeds. Our custom look and style of blogs was gone and only raw information was left.Then we had technorati. Actually I forgot about it completely.Then we had ideajam. This was the first time we had a common place to share our ideas.Then we had planetlotus. Our rss feeds were gone and we got back our blogs, but this time all of them together.Then we had bleedyellow. Our blogs were still there, but we had also duplicate blogs, but we got also new ways of collaboration.Then we had twitter. Our collaboration tools screamed for integration into one single global place, as we have now to update information in 4 or more different places seperately.Planetlotus strikes again, and tries to keep all the places together. But it can do only so much, and it can't fix the source of the problem.I'd like to see one single place for global collaboration.I'd like to see it to running on Domino 8.0.1 on SUSE or AIX.I'd like it to have everything what all the above systems provide plus be easily expandable for future ideas.I'd like that the collaboration starts on the system level, and not only on the end user level.And actually I think it should be in IBM's own interest also to host a global server, as they have the iron. I'm sure they can hack some Blue Gene/P to run like an AIX, and I'm sure many companies and individuals would love to join for monthly fees to host their own virtual server, when they know their site is running on the best hardware in the world.And hey, collaboration could help also on the virtual server level, since not everyone needs their own virtual server, but they could be joined into communities, running on a common Domino server. Also those who prefer an own virtual server, could collaborate and share their idle time, then others, and themselves would have huge benefits from eachothers' idle times using IBM System p hypervisor technology.

      Documentation in Leadwerks 5 will start in the header files, where functions descriptions are being added directly like this:
      /// <summary> /// Sets the height of one terrain point. /// </summary> /// <param name="x">Horizontal position of the point to modify.</param> /// <param name="y">Vertical position of the point to modify.</param> /// <param name="height">Height to set, in the range -1.0 to +1.0.</param> virtual void SetHeight(const int x, const int y, const float height); This will make function descriptions appear automatically in Visual Studio, to help you write code faster and more easily:

      Visual Studio can also generate an XML file containing all of the project's function descriptions as part of the build process. The generated XML file will serve as the basis for the online documentation and Visual Studio Code extension for Lua. This is how I see it working:

      I am also moving all things private to private members. I found a cool trick that allows me to create read-only members. In the example below, you can access the "position" member to get an entity's local position, but you cannot modify it without using the SetPosition() method. This is important because modifying values often involves updating lots of things in the engine under the hood and syncing data with other threads. This also means that any method Visual Studio displays as you are typing is okay to use, and there won't be any undocumented / use-at-your-own risk types of commands like we had in Leadwerks 4.
      class Entity { private: Vec3 m_position; public: const Vec3& position; }; Entity::Entity() : position(m_position) {} It is even possible to make constructors private so that the programmer has to use the correct CreateTerrain() or whatever command, instead of trying to construct a new instance of the class, with unpredictable results. Interestingly, the constructor itself has to be added as a friend function for this to work.
      class Terrein { private: Terrain(); public: friend shared_ptr<World> CreateTerrain(shared_ptr<World>, int, int, int) }; The only difference is that inside the CreateTerrain function I have to do this:
      auto terrain = shared_ptr<Terrain>(new Terrain); instead of this, because make_shared() doesn't have access to the Terrain constructor. (If it did, you would be able to create a shared pointer to a new terrain, so we don't want that!)
      auto terrain = make_shared<Terrain>(); I have big expectations for Leadwerks 5, so it makes sense to pay a lot of attention to the coding experience you will have while using this. I hope you like it!

      An often-requested feature for terrain building commands in Leadwerks 5 is being implemented. Here is my script to create a terrain. This creates a 256 x 256 terrain with one terrain point every meter, and a maximum height of +/- 50 meters:
      --Create terrain local terrain = CreateTerrain(world,256,256) terrain:SetScale(256,100,256) Here is what it looks like:

      A single material layer is then added to the terrain.
      --Add a material layer local mtl = LoadMaterial("Materials/Dirt/dirt01.mat") local layerID = terrain:AddLayer(mtl) We don't have to do anything else to make the material appear because by default the entire terrain is set to use the first layer, if a material is available there:

      Next we will raise a few terrain points.
      --Modify terrain height for x=-5,5 do for y=-5,5 do h = (1 - (math.sqrt(x*x + y*y)) / 5) * 20 terrain:SetElevation(127 + x, 127 + y, h) end end And then we will update the normals for that whole section, all at once. Notice that we specify a larger grid for the normals update, because the terrain points next to the ones we modified will have their normals affected by the change in height of the neighboring pixel.
      --Update normals of modified and neighboring points terrain:UpdateNormals(127 - 6, 127 - 6, 13, 13) Now we have a small hill.

      Next let's add another layer and apply it to terrain points that are on the side of the hill we just created:
      --Add another layer mtl = LoadMaterial("Materials/Rough-rockface1.json") rockLayerID = terrain:AddLayer(mtl) --Apply layer to sides of hill for x=-5,5 do for y=-5,5 do slope = terrain:GetSlope(127 + x, 127 + y) alpha = math.min(slope / 15, 1.0) terrain:SetMaterial(rockLayerID, 127 + x, 127 + y, alpha) end end We could improve the appearance by giving it a more gradual change in the rock layer alpha, but it's okay for now.

      This gives you an idea of the basic terrain building API in Leadwerks 5, and it will serve as the foundation for more advanced terrain features. This will be included in the next beta.

      A new update is available for beta testers.
      Terrain
      The terrain building API is now available and you can begin working with it, This allows you to construct and modify terrains in pure code. Terrain supports up to 256 materials, each with its own albedo, normal, and displacement maps. Collision and raycasting are currently not supported.
      Fast C++ Builds
      Precompiled headers have been integrated into the example project. The Debug build will compile in about 20 seconds the first run, and compile in just 2-3 seconds thereafter. An example class is included which shows how to add files to your game project for optimum compile times. Even if you edit one of your header files, your game will still compile in just a few seconds in debug mode! Integrating precompiled headers into the engine actually brought the size of the static libraries down significantly, so the download is only about 350 MB now.
      Enums Everywhere
      Integer arguments have been replaced with enum values for window styles, entity bounds, and load flags. This is nice because the C++ compiler has some error checking so you don't do something like this:
      LoadTexture("grass.dds", WINDOW_FULLSCREEN); Operators have been added to allow combining enum values as bitwise flags.
      A new LOAD_DUMP_INFO LoadFlags value has been added which will print out information about loaded files (I need this to debug the GLTF loader!).
      Early Spring Cleaning
      Almost all the pre-processor macros have been removed from the Visual Studio project, with just a couple ones left. Overall the headers and project structure have been massively cleaned up.
