General

Kreal designer is web-based 3D modeler that supports basic object transformations. It features easy-to-use user interface, support for 3 major browsers as running platform (Google Chrome, FireFox, Internet Explorer). Kreal designer can be run on PC for editing and saving scenes and on mobile devices (tables) for previewing saved scenes.

Editor

Editor is part of applications that enables users to create base elements or complete assemblies and scenes. Editor is intended to run on PC (desktop PC or notebooks) with keyboard and mouse because editing requires some amount of object manipulations.

Logged user or guest

Functionality is same for logged and guest users. Difference is in saved scenes: scenes saved by guest users are available to all guest users ("public" scenes), scenes saved by logged user are available only to that particular logged user ("private" scenes). Public scenes can be changed/edited by all users, private scenes are, as name suggests, private to each user.

Login and logout

User can login by clicking to button titles "Login" in top right corner of screen. User enters username and password in dialog window and press "Login". After successful login, user's username is displayed in top right corner.

Logout can be done with button "Logout". No additional action is necessary. User's logout status is confirmed by text "guest" displayed as current user.

Manipulating objects in scene

Editor enables user to easily manipulate objects on scene by rotating, scaling and moving objects/assemblies on scene - in scene coordinate system. To manipulate individual object, one has to click on part of object to select it. Selected object has extra coordinate system displayed at object's reference point and translation/scaling/rotation can be selected with buttons in bottom part of screen. Transformations can also be done by changing appropriate numbers in right part of screen.

scaling: After selecting scale, coordinate system is displayed with boxes. Scaling in each direction can be changed by dragging those boxes. translation: After selecting translate, coordinate system is displayed with arrows. Moving object is done by dragging appropriate arrow in desired direction. rotation: After selecting rotate, three circles are displayed - one for rotation about each axis. Rotation is done by click and drag on circle.

Manipulating objects on screen (changing view on object)

Editor enables user to easily manipulate objects on screen by rotating, scaling and moving objects/assemblies. All manipulations are done using mouse, as following:

Scene

Menu option "Scene" groups together options for dealing with scenes. All actions are performed on scenes for currently logged use - scene is saved for current user, load displays previously saved scene of logged user.

Using "public" scene as basis for new (user) scene

There is possibility to use "public" scene (or scene save by any other user) as basis for your scene. Procedure is quite easy:

Edit

Menu "Edit" groups together options to clone and delete of selected object, importing geometry from file or to export parts of scene.

Add

Menu "Add" enables user to add following objects to scene: element (simple object), assembly of multiple objects, full scale examples or directional light. Added object as also displayed on right side of screen in list of elements/objects that can be selected. Only added elements can be selected and manipulated with (delete, move, rotate, scale), e.g. if assembly has 3 elements, only whole assembly can be selected and manipulated with.

Background

Menu "Background" offers user to add/change scene background image. Background image can be selected from list on server (Select background) or loaded from computer local storage (disk, Load background). By selecting "Background on/off" from menu or clicking on button "Background on/off", user can temporary hide background image. Image is not deleted or removed, just hidden. With selecting same option again, image is displayed.

Viewer

Viewer is a "lightweight" version of Kreal designer, intended for use on mobile devices (tablets, mobile phones - device with touch screen, without keyboard and mouse) to preview already prepared scenes. Because input capabilities of mobile devices are very limited, there are no editing functionality but viewer offers same preview capabilities as editor. All functionalities are arranged in menu options, shown on right side of screen and all instantly accessible.

With loaded scenes, user can change view and position of objects in screen and also change background image.

Here is a preview of viewer's capabilities:

Manipulating objects (scenes) in screen

Viewer does not offer any editing functionality and only manipulations with objects in screen include: rotation, translation and scaling.
