3D Image

The 3D View | Tools | Import Image ()command imports an image and displays it as a slice in the 3D View window.

This image shows a 3D View with three images oriented over a surface topography grid.

Properties

Properties for an image in the 3D View are described below.

Properties available for an Image
in the 3D View.

General

Input File

The Input File lists the file path and file name of the imported image file

Reload

Click the button to load an updated version of the image from the Input file location

Change File

Click the button to display the Import dialog. This allows you to select a new image or an updated version of the current image to display. If the file exceeds the current model limits, you will be prompted to adjust the limits.

Pixel Format

All images are converted to 32 bits/pixel BGRA format for use in the 3D View.

Size (pixels)

Displays the pixel dimensions of the input image file

Size (bytes)

Displays the image file size in bytes.

Quality

Adjusts the quality of the image display. As the quality is decreased from 100, the number of pixels used to display the image is decreased. A quality value of 1 will result in a mostly unrecognizable image.

A lower quality may improve rendering speeds for large high resolution images.

Opacity

Change the Opacity of an image by entering a value from 0% (completely transparent) to 100% (completely opaque) or dragging the slider to change the opacity percentage.

Spatial Extents

The spatial extents are used to position the image in the 3D model.

GeoTIFF images are imported in the XY plane at the central Z position. By default, the X and Y coordinates of the georeferenced image are used to position the image on the XY plane.

All other images are imported to the YZ plane at the central X position by default.

Use Georeferencing

The Use georeferencing box is checked by default when a GeoTIFF is imported. Uncheck this box to manually adjust the XY coordinates of the image

Z position

Move the image up or down in the model by adjusting the Z position.

Type a new value or click and drag the to the desired Z value.

Orientation

Choose the direction of the image in the 3D model. Choices include XY plane (axial), XZ plane (coronal), or YZ plane (sagittal). To change the Orientation, click on the existing option and select the desired option.

XY

Images oriented on the XY plane have the following coordinate options. To adjust the orientation using these options, enter a value or click and drag the slider. The slider values are based on the corresponding axis extents.

  • The Z position determines where along the Z axis the image is placed.

  • Left X controls the placement of the left side of the image.

  • Right X controls the placement of the right side of the image.

  • Top Y controls the placement of the top of the image.

  • Bottom Y controls the placement of the bottom of the image.

XZ

Images oriented on the XZ plane have the following coordinate options. To adjust the orientation using these options, enter a value or click and drag the slider. The slider values are based on the corresponding axis extents.

  • The Y position determines where along the Y axis the image is placed.

  • Left X controls the placement of the left side of the image.

  • Right X controls the placement of the right side of the image.

  • Top Z controls the placement of the top of the image.

  • Bottom Z controls the placement of the bottom of the image.

YZ (default)

Images oriented on the XY plane have the following coordinate options. To adjust the orientation using these options, enter a value or click and drag the slider. The slider values are based on the corresponding axis extents.

  • The X position determines where along the X axis the image is placed.

  • Left Y controls the placement of the left side of the image.

  • Right Y controls the placement of the right side of the image.

  • Top Z controls the placement of the top of the image.

  • Bottom Z controls the placement of the bottom of the image.

Custom

Images with a custom orientation allow you to define the X, Y, and Z coordinates for the Top left corner, Top right corner, Bottom left corner, and Bottom right corner. To adjust the orientation using these options, enter a value or click and drag the slider. The slider values are based on the corresponding axis extents but any value can be entered.
