## View Header

There are buttons for controlling displays in the [View Header] on the top of each view.

### View change

When the title of a 3D view is clicked, the following menu will be shown. It switches a perspective view and an orthogonal view and also changes a view angle. In the three orthogonal views, it switches perspective, orthogonal, top, front, left, bottom, back and right views.

[Capture and save] saves the displayed image to a file or a clipboard.

### Point/Line/Face

When the buttons are clicked, points, lines or faces are shown or hidden.

When you click the buttons with Shift key, only the element of the button is shown.

### Simple

When the simple button is on, patches, blobs and so on are displays as simple shapes.

[Simple] is ON | [Simple] is OFF

When you right-click on the button, a menu will be shown. You can select the target to display simply.

### Front

When the button is on, only the front side of vertices and lines are shown.

ON | OFF

You can specify the opacity of backside of lines when the front option is off in [Display > Line > Back line opacity] in Configuration.

### Display

It selects display options for a view.

#### For each view

XY/YZ/ZX plane
  It displays the XY, YZ, or ZX plane as a mesh on the 3D view. When you click the icon, you can execute [Set Grid].
Scale
  It displays a scale by a constant interval on the X, Y or Z axis. When you click the icon, you can execute [Set Grid].
Axes
  It displays X, Y and Z axes.
Symmetry plane
  If [Edit Option > Sym] is available, [Symmetry plane] is displayed. This plane is the reference plane of symmetric edit.
Background image
  It specifies whether to display a background image in the view. When you click the icon, you can execute [Set Background Image].
Alpha
  It selects from [Disable] or [Enable], [Correct depth] how to display semi-transparent objects. Objects on the backside may be not displayed in the [Enable] mode when the semi-transparent objects overlap multiple in the depth direction. [Correct depth] displays them correctly, but it is not available in OpenGL display.
Textures
  It specifies whether to display textures.
Smooth shading
  It specifies whether the display a surface of an object smoothly. It can show the surface of the object smoothly. It delays a little to show.

  ON | OFF

Shader
  Specifies how to handle shaders other than Constant/Phong.

  Enable | Use all shaders.
  Without edge | The contour lines in the PMD/VRM shader will no longer be displayed.
  Disable | Disable shaders other than Constant/Phong, and display with Phong shader.

Lighting direction/color
  It specifies whether to apply lights' direction/color for displaying faces. When this check is off, only one light is applied. When you click the icon, you can execute [Lighting Settings].
Occlusion (only EX edition)
  It specifies whether to display dark areas in deep areas. The occlusion can be displayed in [Direct3D 11] only. When you click the icon, you can execute [Occlusion] setting.

  Occlusion ON | Occlusion OFF

Clip plane (only EX edition)
  It is to switch ON/OFF clipping display.
  When clipping display is available, objects are displayed only one side with the clip plane as the boundary.

  One side with the clip plane as a boundary is hidden.

  The position of the clip plane is specified in [View > Clip plane] command.
View Panel
  It can numerically input a direction and a position of the camera, clipping and shadow parameters, and can initialize the viewpoint. You can also change the target view in [Target]. When you choose this menu with pushing the shift key, the viewpoint is initialized without showing the dialog.

  Angle | Specify the orientation of the camera in the head, pitch and bank.
  Zoom | Specify the area visible from the camera by Zoom/Pers or FOV/Distance.
  Position | Specify coordinates of the rotation center and camera position.
  Clip | Specify the distance range from the camera to which objects will be displayed by front and back clips. If the front clip is too far away, the display of nearby objects will be lacking, but if it is too close, the distortion of nearby objects will increase. Also, if the clip range is too wide, the depth determination becomes less accurate and the front-to-back relationship may be displayed inaccurately.
  Occlusion | For [Occlusion] settings, specify Width, Power and Bias.
  Record | Up to eight viewpoints and edit options can be recorded and restored. Clicking with the Shift key or right-click menu will record the state, and simply pressing the button will restore. By default, you can also use (Shift+)F5-8 to do the same.

Reset
  It restores the view state to the initial one.

#### For all views

Show only faces in a current object
  It shows only faces in a current object.
Show line of uncurrent objects
  It specifies how to show vertices and lines of objects excluding a current object.

  Normal | It shows vertices and lines with the assigned color to the object.
  Dark | It shows lines by the color specified in [Display > Color > Dark] in Configuration.
  Hidden | It hides vertices and lines.

Show selected parts only
  It shows the selected vertices and lines only, and hides the unselected part.
Lines overwrite faces
  It always shows vertices and lines overwrite faces without considering for the z-order.
Show back faces by force
  It shows back side faces in red.

  ON | OFF

Highlight open edges
  It highlights lines that are not shared by other lines.

  ON | OFF

Show subdivision wires
  It displays or hides subdivision wires.

  ON | OFF

Display unit (only EX edition)
  It selects the display unit from [None], [mm], [cm], [m], [km], [in] and [ft].
Renderer
  It selects the rendering method for the preview.

  Direct3D | The default display in Windows. Please use this unless you have some troubles.
  OpenGL | [Occlusion] and [Correct depth] for alpha is not supported.

### Synchronize

Operations in the view header on each view (Point/Line/Face /Simple/Front display, view scaling, view move) are synchronized.

### Zoom

When you drag this icon, the view is scaled.

This operation is same as the wheel rotation in the view.

### Move

When you drag this icon, the view is moved.

This operation is the same as the middle-button dragging in the view.

### Rotate

When you drag this icon, the view is rotated.

This operation is same as the right-button dragging in the view.

### Layout

You can select the view layout.

And you can also add a current view layout as a new item by [Register current layout]. The registered layout can be deleted by clicking the icon.

### Single view / 4 views

It switches the display to a single view or 4 views.

Single view | 4 views
