The Selection tools allow you to mask specific areas of the subject you are working on. Once a selection is made, it will appear with a blue overlay. When the mask is being applied, the overlay will turn red.

All three tools operate on the same basic principle: simply drag the cursor over the desired area, and than click the “Mask selection” button  Refresh icon  to apply the mask.

 

  • Rectangle selection: drag a rectangle and click the “Mask selection” button to mask the selected area.


  • Polygon selection: use the mouse “left-click” button to add nodes to the polygon path and double-click to automatically close it. Press the “Mask selection” button to confirm the selected area.


  • Lasso selection: drag the lasso and click the “Mask selection” button to mask the selected area.


A mask subsection can be removed using the “Clear mask selection” button  Refresh icon  with all the three Selection tools.

The Brush tools (also known as the Silhouetter tools) are used to manually create masks or refine those generated by the Automagic tool.
3DF Masquerade uses its algorithm to propagate the mask automatically, leveraging the strokes provided by the user. High contrast between the background and the subject improves the tool’s effectiveness in generating accurate masks.

 The tool requires at least the following strokes to function:

  • Foreground stroke (red): areas marked with the red stroke will be included in the mask.


  • Background stroke (blue): areas marked with the blue stroke will be excluded from the mask.


To start using the tool, click on the “Foreground stroke” (1) button to activate the red stroke, then left-mouse to mark areas of the image. To mark the background, either click the “Background stroke” (2) button or hold the “shift” key drawing with the “left-mouse” for applying the blue stroke. The brush size can be adjusted using the Brush size slider (3).


Clicking on the “Compute mask” button Refresh icon will generate the mask propagating the stroke, additionally the Automated Masking after each stroke command Refresh icon can be enabled to compute automatically masks after each stroke applied to the image.
