About the Paint tool

The Paint tool in Human Studio allows you to apply colors and visual effects to an anatomical structure or group of structures in your 3D model. Use Paint to:

• Distinguish multiple structures from one another (for example, the lobes of the brain)
• Demonstrate anatomical relationships, or identify specific structures within the larger context of the body or surrounding region (for example, show where the gallbladder is positioned in relation to the liver)

• Visually identify groups of structures

  Tip: Use labels to further reinforce and provide more information about these structural groups.

• Customize the look and feel of your model

Apply colors and effects with Paint

There are two ways to apply colors and effects to your model with the Paint tool:

• Select a color or effect from the Paint tool and then apply it directly to the model. This method is best for painting just a few structures.
• Select one or more structures in the Anatomy Tree, select a color or effect from the Paint tool, and apply it to those structures. This method enables you to paint many structures at once.

Choose the option that best suits your needs and follow the steps below:

• To quickly paint one or a few visible anatomical structures, take the following steps:
  1. Select the    brush icon in the toolbar in the upper-left corner of the canvas.
  2. Expand the Paint menu in the tool panel on the right.
  3. Select a color from the default palette, or create a custom color or effect. Your cursor will change to a paint brush icon.
  4. Click directly on the structure(s) you would like to paint.
  5. Repeat as needed to apply additional colors or effects.
  6. Click Save in the upper-right corner of the page to save your changes.

• To paint multiple structures at once, such as a whole organ system, or to paint structures that are hidden or difficult to select directly, take the following steps to paint them using the Anatomy Tree:

  1. Open the Anatomy tab on the left side of the page.
  2. Make sure “Tree” view is enabled, and select the structures you want to paint. Hold down the Shift key to select multiple structures or groups at once
  3. Select the    brush icon in the toolbar in upper-left corner of the canvas.
  4. Expand the Paint menu in the tool panel on the right.
  5. Select a color from the default palette, or create a custom color or effect.
  6. Repeat as needed for additional groups or structures.
  7. Click Save in the upper-right corner of the page to save your changes.

  Tip: You can also select one or more structures and then use the bulk-action menu to "Select Everything Else." This is particularly useful for apply de-emphasizing effects such as Grayscale and Glass to secondary structures in your model.

How to create custom paint colors

The default BioDigital palette comes with 10 ready-made colors and effects designed to work well across a wide range of 3D models. However, the possibilities are endless with our advanced Paint options.

To create a custom paint color, take the following steps:

Next steps

Now that you have learned to paint your model, you can:

• Create and manage custom paint palettes to access your custom paint colors and effects later
• Change your model's background color to complement your painted model
• Add labels to identify and distinguish structures on your painted model
