3D Editor User's Manual/Window


■Main window

This is a window for basic editing work.


■"File" menu

Performs file management such as input/output of model files. Processing such as termination is also executed from this menu.
◆Open
Open an already saved SG3 format file. If the file is already open, it will be automatically closed.
Note!
Only one map file can be edited with "3D Editor".

◆Save
Save the file you are currently working on in SG3 format.

◆Save as another name
Give the file you are currently working on a name and save it as a separate file.

◆1~4
Four files will be displayed in order from the most recently opened or saved files.

◆End
Close "3D Editor".

■“Edit” menu

Extend selection of polygons. You can also set the work environment for using "3D Editor" here.
◆Restore
Cancels the previous operation. Please note that some functions cannot be canceled.

◆Cut out
◆Copy
◆Paste
◆Delete
This currently can not be used.

◆Tools
Each submenu corresponds to a button in the toolbox.
Rotating the model
Moving the model
model scale
Polygon selection
Moving the cutout texture

◆Model selection
Selects the entire model, including the currently selected polygons.

◆Material selection
Selects all polygons that have the same material information as the currently selected polygon.

◆Select all
Select all polygons included in all models.

◆Deselect
Deselects all polygons in all models.

◆Properties
Configure various environment settings.

【Color】
Specifies the color assigned to the expression and function of each editing task.

●Background color
Specify the background color.

●Selection polygon
Specifies the color of the mesh used to represent the selection polygons.

●Transparent color
Specify the color to be treated as the transparent color when editing texture data.

●Custom color dialog
If checked, a custom dialog using RGB sliders will be displayed for the color selection dialog.
If not checked, the standard Windows color selection dialog will be displayed.

【drag】
Select how the model is displayed during mouse drag operations on the main window, such as rotating or moving. It is mainly used for the purpose of absorbing operability problems caused by speed differences between development machines.

●Displayed in wireframe
Displays the model in wireframe while dragging. This is the most comfortable way to operate.

●Displayed as flat polygons
While dragging, the model will be displayed as polygons (non-texture map) with light source calculations. Although the processing speed will be slightly slower, this method allows you to maintain the model's expression to some extent even while dragging.

●Displayed under all conditions
The display does not change even while dragging. Although the conditions vary depending on the content of the material information, this is the operation method that requires the most processing.


■"Display" menu

Show/hide subwindows and toolboxes. Target display processing compatible with "SS Monitor/SS Viewer" is also performed here.

◆Tool box
Show/hide the toolbox.

◆Attributes
Show/hide the attribute window.

◆Hierarchical structure
Show/hide the hierarchical structure window.

◆Texture list
Show/hide the texture list window.

◆Target display
Transfer/display the currently working file to the target. To use this feature, "SS Monitor" must be started and "SS Viewer" must be running in advance.

●Texture
Transfer texture data.

●Model
Transfer model data.
*For texture map data, only the texture number information of each surface's attribute data is transferred. Actually, in order to apply a texture map to each surface, it is necessary to separately transfer texture data corresponding to the model.

●Environment
Transfers environmental information such as the direction and color of the light source and the environment (ambient) color.

■“Options” menu

Set up the 3D environment such as light source, projection surface, camera, etc. Special operations on vertices and faces are also performed here.

◆Light source settings
Set the direction and color of the light source.
"direction"
Move the control point displayed as a red circle to specify the direction of the light source.
●Front
Specify the front hemisphere area.
●Back
Specify the back hemisphere area.

"Color"
Specify the color of the light source and environment.
●Light source
Specify the color of the light source.
●Environment
Specify the environment color (ambient).

◆Screen settings
Configure various settings related to the 3D projection surface (screen).
"Projection settings"
Select the projection method to the screen.
●Parallel projection
Projects ignoring depth (Z value).
●Perspective transformation
Perspective and project according to the depth. Normally, select this.

"Viewing angle"
●Slider
Specify the extent of the projection range relative to the line of sight in degrees. This is an invalid parameter if you select "Parallel projection".

◆Camera settings
Select the default camera (reserved viewpoint position) or custom camera (user-specified viewpoint position).

◆New camera
Adds the current viewpoint as a new custom camera with the number selected in the submenu. If you select a camera that already exists, it will be replaced with the current viewpoint.

◆ Rotation of vertices (only when selecting polygons)
Changes the definition order of the vertex numbers that make up the selected polygon. Mainly used when you want to change the texture mapping direction without changing the texture data. Please note that if you apply this menu to triangular polygons, the saved data may no longer be usable in SGL, etc.
・90 degrees clockwise
Rotates the vertex number definition 90 degrees clockwise when viewed from the polygon table.
・90 degrees counterclockwise
Rotates the vertex number definition 90 degrees counterclockwise when viewed from the polygon table.
・180 degrees
Rotates the definition of the vertex number 180 degrees clockwise when viewed from the polygon table.

◆Reverse front and back (only when selecting polygons)
Change the definition order of vertex numbers so that the normal vector of the selected polygon faces in the opposite direction. If a texture has been applied, manipulate the texture inversion flag in the attribute information to preserve the original image.

◆Plugin

●Groulow table generation
If real-time Gouraud (Gouraud shading that calculates the light source) is applied to the attribute information of the selected polygon, change it to Gouraud shading that uses a fixed table (does not calculate the light source). The Gouraud table is generated by applying the color and direction of the current light source.
It is mainly used for the purpose of easing the processing time of real-time Gouraud (which takes relatively long time to process).


■“Help” menu

Displays a help file that explains how to use "3D Editor". Also displays information about "3D Editor".

◆Table of contents
Displays the table of contents of the help file.

◆Version information
Displays information such as the version of "3D Editor".
