The INT3D-editor has 10 main control panels.
All the command keys of the INT3D-Editor have instructions about their use: move the mouse over them and this information will be seen on the information bar (bottom of the screen).
The INT3D-editor has three main use modes:
1. "Build" - mode for building/editing the scene: makes it possible to set position, angle and properties concerning each object. This mode automatically starts when the INT3D-editor begins working, and it is also accessible by clicking on the "Build" key (Panel I).
2. "List" - mode for a preliminary viewing of the models from the catalogue. It allows choosing and adding models into the scene. Click on the "List" key (Panel I) to start this mode.
3. "Tour" - mode for interactively viewing (walking) the scene. By clicking on the "Tour" key (Panel I), or "PageDown" key, from the keyboard all the control panels go away. Pressing "PageDown" again makes it possible to return to the editing modes.
We advice starting the work after setting the right scale of all the panels on the screen. Click on "Adjust" (Panel I), click&drag the double arrow key and set your preferred panel dimensions. Then click on "Adjust" again to switch the central key off.
You can also move each panel like a normal "window" program.
If you want to edit an already finished scene you need to wait for it to loading fully before starting work.
Camera / Background
On first line of the "List of all elements in the Scene" Panel I, there is the "Camera" element.
Once selecting it on Panel I, it is possible with the "Object" key (Panel III):
- To set the field of view (degrees) of the camera in "Tour" mode.
- To modify the overall scale of the scene.
- To set the colour(s) of the background.
- To set the type of navigation in "Tour" mode: 1-walk, 2-study, 3-fly or 0-none.
- To set the height of the camera above the ground when you walk in the scene in "Tour" mode.
- To set the headlight: it is a directional light that always points in the direction the user is looking.
Changing such parameters should be very easy and intuitive. However, for a better explanation of how to do it, see below at "How to change properties of an object"
How to select an object
To change the position, angle or properties of an object, select that object. There are two ways of doing it:
- Directly select that element on the Panel I - click on the field of the object.
- In the "Build" mode, activate the "Find" (Panel III) function by clicking on the related key and then click on the object in the Scene.
How to modify the position of a selected object in the scene
It is easy to move each object on the scene with the INT3D-editor. You simply have to select the element/object to be moved and then set its position with Panel III. There are many ways of doing it:
- Click and drag with the mouse on the "directional arrows" keys (Panel III).
- Activate the "Linear" (Panel III) function which makes the three pertinent axes X,Y,Z visible. Then click directly on the axis along which you want to move the selected object and drag it with the mouse. In the same way, activating the "Angular", key, it is also possible to rotate the object in relation to the three axis. Functions "Snap to" and "inTour" are also very useful for this method.
- Activate the "Touch&Set" function (Panel III). Then click at the desired point in the scene. This method is very useful for inserting windows and doors quickly into the apertures in the wall. Activating only "Touch&Set", the object is positioned, maintaining its starting orientation (in relation to the axes X, Y, Z). Activating both "Normal" and "Touch&Set", changes orientation of the object, positioning it perpendicular to the clicked surface.
- Setting its co-ordinates. Just click on "Object" (Panel III) and put the numerical data (with Panel VI) on Panel VIII. It is possible to use the keyboard for setting position and rotation values - try using the "+", "-" keys and the "cursor arrows".
How to remove objects from the scene
Every object (but not the "Camera") can be easily removed from the scene. To do it, select it and click "Del" key on Panel I.
In some cases it could be very useful to hide an object/element from the scene without removing it.
To do it, select it and then click "Hide" key (Panel I). Click "Hide" again to make it reappear;
"All" reveals all the hidden elements/objects;
"None" hides all the elements;
"Inv" is used to invert (switch) hidden and visible objects: this function is very useful in complex scenes in making only one (or several) objects visible - first the element(s) that you want to view separately have to be hidden. Then click "Inv".
How to add objects to the scene
To add new objects to the scene you need to change mode, going to "List" (Panel I).
From the models catalogue (Panel IV) choose in consequence:
- Base elements or Furniture;
- Group of elements (Bases, Sofas, Tables ..);
- Model (for example: chair "Linda");
- Variant of the model ("a", "b", "c" ...).
The chosen model will appear on the screen and it will be possible to view it on all sides using the keys on Panel V. To add the chosen model to the scene, just click "Add" on the Panel V. You will see the new object in the list on Panel I. Going back to "Build" mode it will be possible to set its position on the scene.
How to copy objects into the scene
To copy objects/elements into the same scene just select it and click "Copy" (Panel I). ). The copied object/element will keep the same properties, position and orientation of the original. To change properties and position you have to use Panel III.
How to change the properties of the object
To change the properties of an objects (such as dimensions, proportions ...),
you have to select it and then click "Object" (Panel III in the "Build" mode)
or "Preset" (Panel V in the "List" mode). Panel VII (object properties) will appear on the screen and with it you will be able to set the new parameters (putting numerical values using Panel VI or with the keyboard).
How to set materials and textures
At the bottom of Panel VII in view (see previous paragraph) there are the "m1"-"m8" materials key. Clicking on each of them a further Panel X (Panel of materials and textures) will appear on the screen, with which it is possible to set or change all related colours and textures of materials.
The INT3D-Editor uses the two most common and important systems of colour setting: RGB and HSV to move from one system to the other just click on the "RGB/HSV" key(Panel X) with the mouse. This enables obtaining an infinite range of colours and effects.
If you click on "None" (at the top of Panel X), no textures will be applied to the selected object, but you can set its colour and futures by clicking on the "Textures/Materials" key and using the RGB/HSV parameters activate the: "diffuse color", "specular colour", "emissive colour", "ambient intensity", "shininess" and "transparency" functions. An infinity of solutions can be obtained such as, for example, metal, glass, plastic and other effects.
Note: On the left side of the "Transparency" key there is a small arrow. Clicking and dragging it with the mouse the panel can be enlarged with all its parameters, creating a wider and more precise possibility of choice.
260 textures are positioned on the panel which will be constantly increased and updated over time.
At present they are subdivided into 16 categories (wood, parquet, slab, stucco, greyscaled, stone, marble, leather, abstract, geometric, fabric, brick, ornament, tile, flora, plank). Just click on the desired texture to apply it automatically to the selected object (or a part of it). The "Rot" and "Scl" functions enable setting the rotation angle and the scale (proportion) of the texture, while the small black circle placed between "Rot" and "Scl" is useful when you need to fit the textures to the object/element.
Once the texture has been chosen, by clicking on the "Textures/Materials" key you can easily set features and effects such as:
- tonality: acting on the RGB or HSV parameters with the "emissive colours" function;
- light reflection capacity: with the "specular colours" function;
- brightness: with the "ambient intensity" function;
- brillaince: with the "shininess" function;
- lucidity: acting on the "V" parameter (in HSV mode) with the "specular colour" function;
- transparency: with the "transparency" function.
We advice becoming familiar with all the various functions of this editor, carrying out a number of trials and trying to set all the different parameters available, because the possibilities are truly endless.
We also recommend paying attention to the two "Copy" and "Paste" keys (Panel X). They are extremely useful, because they enable copying a type of colour and texture with all their related parameters and effects from a selected object and applying it to others.
To switch off the editor of the materials and textures panel, click on "OK" (bottom right).
How to save the scene
The scene can saved at any phase, even after disconnected from Internet (offline mode).
This function is not complicated, but it needs attention and accuracy.
To save the scene, click the "Save" key (Panel I). There are two different options:
- "Save to internal-format (for future edit)": this option allows the user to edit and modify the saved scene in the future.
- "Save to external-format (for publishing)": this option enables saving the scene as a normal vrml 3D scene prepared for viewing offline and for publishing on Internet. This format however does not allow future editing.
- "Save as external block for another scene": this option enables saving the scene in external-format as well, but without some irrelevant data. It must be used for saving scenes to be imported into other scenes (with the "Add object from URL" function). This format does not allow future editing.
The INT3D-editor will prepare the saving procedure in all three options.
This operation might take several minutes (depending on the number of elements in the scene) and a new window will appear on the screen with the text of your INT3D-scene.
It will also be possible to read the advice regarding the saving procedure in that window.
The obtained text needs to be saved as a file and this operation must be made in different ways for different Internet-browsers:
To save the scene correctly in Internet Explorer:
Choose "View" -> "in HTML" (or Source)-> opening Notepad;
In Notepad - "File" -> "Save As..";
The Name to be saved should have a structure such as: anyname.wrl (for example: great.wrl).
To save the scene correctly in Netscape Communicator:
Choose -"File" -> "Save As..";
The Name to be saved should have a structure such as: anyname.wrl (for example: my5.wrl).
It is possible, that from Netscape Communicator you should press button "Save" (Panel I) twice before new window with the text of your INT3D-scene will appear.
If you have problems with saving try another method:
Select and copy all the text in this page: press "Ctrl-A",then "Ctrl-C";
Open Notepad and paste text from memory: press "Ctrl-V";
In Notepad choose: "File" -> "Save As.. ";
Name for saving should have such structure: anyname.wrl.
To reload the saved scene, simply open that file.
