AlternativaPhysics at your disposal!

Today on December the 20th of 2011 we successfully released the first public build of AlternativaPhysics engine. The technology is provided as SWC-library. You can use it free of charge even in commercial projects, but it is required to put a link to alternativaplatform.com in your project.

AlternativaPhysics is a library for simulation of physics interaction of different bodies. It allows you to work with different geometric shapes and it is integrated with Alternativa3D for easy and convenient usage.

AlternativaGUI – an easy way to create an integrated interface

A library for creating user interfaces AlternativaGUI has been published. Download it from the official website of AlternativaPlatform company in GUI section. The library is free and can easily be used, including in commercial projects. According to the license agreement you only need to specify in the project the page link alternativaplatform.com.

AlternativaGUI provides greater flexibility in terms of creating new components or modifications of existing interface, which is achieved by using only the core classes. The library offers a wide range of user interface elements such as buttons, containers, container line, scrollbar, tools for working with raster graphics and more.

AlternativaGUI Features

  • High performance
    Performance is achieved by the efficient work of all components of the interface in a single system. At the base classes implement only the required functional, hence the low consumption of resources.
  • Flexibility
    The library allows to create various graphics and can control their properties. Simplicity and clarity of API library allows you to extend all the classes are very easy to add and it is so functional that you need.
  • LOD elements
    AlternativaGUI allows you to develop an interface for different screen resolutions. This is accomplished by using different LODs for UI-elements (LOD – Level Of Details) and the correct scaling (for components with raster graphics). Each element has several LOD graphics states. When switching LOD may change the font size, icon size, can be hidden unimportant elements or, conversely, offers additional information. This logic is described by the developer. LOD switching is automatic. A special use of LOD is the development of interfaces for mobile devices with different screen resolutions.
  • The quickness of creating unique component
    Through the use of base classes, the creation and management component runs on a deeper level. Base classes do not contain any graphics, and determine only the logic of the components.
  • User friendly API
    Working with components AlternativaGUI is like working with the standard classes such as Sprite.

For rapid prototyping interface was developed the skinned library AlternativaGUI Default Theme, which contains the basic components. This library is available with source code.

Online viewer updated

Meet fresh update of online 3D-models viewer editor.alternativaplatform.com.

Change list:

  • we added 3ds format support;
  • now you can display model animation;
  • we added possibility to export scene to A3D format;
  • we redesigned interface.

Also in new viewer version we realized more detailed diagnostics of Engine and Flash Player limits violation with uploaded model. For example, if vertices quantity in any object exceeds the limits, user receives notification.



Alternativa3D update and A3D format specification

In the new version we added 3DS format parser, the method of finding a ray intersects with an object of Mesh type and realised export to the binary format.
Download Alternativa3D 8 engine.

A3D binary format now supports the objects of Skin type and the light sources.
Download format specification.
Download 3DS Max 2010 plugins for exporting to A3D format.
Download 3DS Max 2011 plugins for exporting to A3D format.

Also we made changes in the model viewer editor.alternativaplatform.com.

New in Alternativa3D 8.17.0:

  • ParserA3D: added the import of objects of Skin type and the import of light sources;
  • Added Parser3DS class for import models from 3DS format;
  • Added intersectRay() – The method of finding a ray intersects with an object of Mesh type;
  • Added AxisAlignedSprite class to display plane oriented along one axis to the camera;
  • Export to the binary format A3D is supported;
  • Added debug mode displaying of objects bounds;
  • Added primitive Plane;
  • GeoSphere primitive has normals and tangents of vertices after creation;
  • Normalmaps supported with left-sided system of coordinates in StandardMaterial.

Changed in Alternativa3D 8.17.0:

  • Decal: removed the offset property and changed the logic of work;
  • StandardMaterial: fixed a bug with lighting of some light sources;
  • FillMaterial: color in construstor is grey by default now;
  • Box: constructor is optimized;

  • Automatic dividing of the skin with large quantity of bones;
  • Various improvements to the interface, fixed bugs.

AlternativaPlatform demonstrated its technologies in the Adobe MAX 2011

Adobe MAX 2011 conference takes place in Los-Angels from the 1st to the 5th October 2011. We are the gold sponsor of this event and present there our latest technologies for displaying hardware accelerated 3D graphics in Flash Player environment. As part of the “Amazing new possibilities in Flash with Alternativa3D” session CEO Alexander Karpovich and art-director Ivan Zykov told about the prominent features of the graphics engine Alternativa3D 8.

Developing and launching projects on Alternativa3D 8 is possible today as far as public version of the Flash Player 11 was successfully released. This marked the beginning of the next phase in the history of browser-based games and applications. To demonstrate the capabilities of the new Flash Player in an official presentation at Adobe MAX 2011, Adobe has used the browser-based online game “Tanki Online 2.0″ – one of our key projects.

For several years we have been working with Adobe Systems, acting as a regular participant of prerelease groups and as a successful developer of browser-based next-generation games. We are confident that in the near future major game projects move into browsers, as the boundary between the platforms will be erased. With graphics technology Alternativa3D and server side AlternativaCore you can create a common game space where users come from different browsers, operating systems, social networks and with different devices, whether compact notebook or bulky computer at home. It is for this principle the “Tanki Online 2.0.” game was developed.

Along with the graphics engine and server-side, we are developing our own online editor AlternativaEditor. Already, you can use it as a free tool for publishing 3D-models. After loading the model at editor.alternativaplatform.com user gets a link and code for embedding an object into his blog or website. Subsequently AlternativaEditor will also be available to our partners as a complete tool for changing the game parameters and moving objects in real time directly from inside the game.

AlternativaEditor

You can see some of our technologies in action in an interactive demonstration of “Tanki Online 2.0″ on the maps “Arena” and “Crash” as well as in a promotional game MAX Racer, created at the request of Adobe Systems to demonstrate the Stage3D (Molehill 3D APIs) at Adobe MAX 2010.
