Masking Tools

The Lightform workflow is powered and automated by the scan image. In order to customize the look and feel, users add custom masks to control the desired outcome. Masks indicate the regions where content should be projected in a scene. 

Use the following masking tools to create a mask. 

  1. Pen Tool
  2. Shape Tools (Rectangle Tool, Ellipse Tool)
  3. Magic Wand
  4. Magic Brush
  5. Brush Tool

Pen Tool

Our Pen Tool is designed specifically for using vector paths to create clipping masks for projections. To activate the Pen Tool, click on the Pen Icon on the Toolbar or press P.

Click on the artboard to place a point. Click+Drag while placing a point to add control points to that point, which makes both edges it is attached to into a bezier curve. After you've placed a point, ⌘/CTRL+Click+Drag on the point to create a bezier curve with two control points, or ALT/option+Drag on the point to create one control point at a time. 

The same editing abilities in Edit Mode are also available here: Click+Drag a control point to edit the location of both control points - the control point that is clicked is freely translated and the opposing control point will move to keep the curve smooth. ALT/option+Drag will allow editing of only the control point clicked, leaving the opposing control point unaffected, which creates a corner in the curve. ⌘/CTRL+Click+Drag a control point to edit the location of both control points and to mimic the translations done to one control point on the opposing control point.

Finish a custom shape with the pen tool by closing the shape, clicking the Done button or pressing the enter key. To escape out of the pen tool, press esc.

Shape Tools

The Shape tools are the Rectangle and Ellipse tool.

Rectangle Tool

To activate the Rectangle Tool, click on the Rectangle Icon on the Toolbar or press RClick+Drag in the artboard to create a rectangle. SHIFT+Click+Drag to create a square. Release to finish the mask. (Make sure the SHIFT key is still pressed on release for square masking).

Ellipse Tool

To activate the Ellipse Tool, CTRL+Click on the Rectangle Icon on the Toolbar or press EClick+Drag in the artboard to create an ellipse. SHIFT+Click+Drag to create a circle. Release to finish the mask. (Make sure the SHIFT key is still pressed on release for circle masking).


Magic Wand

The Magic Wand tool selects pixels of the scan image (either color or disparity) that are similar to the pixel at the click location.

To activate Magic Wand, click on the Magic Wand Icon on the Toolbar or press W. Click the Done button when you are satisfied with your Magic Wand selection. A final mask with adjustable vertices will be created based on the selection.

Add & Subtract Mode

Choose between positive and negative strokes  the mask is continually updated based on new positive/negative strokes. Positive strokes provide information that we want to retain or add in the selection. Negative strokes provide information that we want to remove from the selection.

Tolerance

Adjust the color tolerance value with the Tolerance slider. When you click with the Magic Wand, your selection will consist of connecting areas that are a similar color to the original clicked pixel, based on the set color tolerance. A lower tolerance selects a smaller range of colors and a higher tolerance selects a larger range of colors, which results in a larger selected area (higher tolerance = larger selection).

Color/Disparity

Lightform Creator provides vision assisted tools that leverage both RGB information and Depth information. Toggle between Color and Disparity to switch from a color-based selection and a disparity-based selection.

Connectivity

If Connected is selected, all adjacent pixels within the tolerance range are selected. Otherwise, all pixels across the artboard in the tolerance range are selected.

Modify Edge

Grows or shrinks the selection by a set number of pixels (between 1px and 10px).

Fit Accuracy

Adjust the allowed error between the mask and the generated curve. Higher values mean more vertices and a closer fit.


Magic Brush

As you drag with Magic Brush, your selection stroke automatically extends to include parts of the image that have continuity in the RGB information.

To activate Magic Brush, click on the Magic Brush Icon on the Toolbar or press Y. Click the Done button when you are satisfied with your Magic Brush selection. A final mask with adjustable vertices will be created based on the selection.

Add & Subtract Mode

Choose between positive and negative strokes  the mask is continually updated based on new positive/negative strokes. Positive strokes provide information that we want to retain or add in the selection. Negative strokes provide information that we want to remove from the selection.

Brush Size

Adjust the brush tip size with the Brush Size slider. This will control the selection expansion size as you drag to expand it outward.

Tolerance

Adjust the color tolerance value with the Tolerance slider. When you click with the Magic Brush, your selection will consist of connecting areas that are a similar color to the original clicked pixel, based on the set color tolerance. A lower tolerance selects a smaller range of colors and a higher tolerance selects a larger range of colors, which results in a larger selected area (higher tolerance = larger selection).

Color/Disparity

Lightform Creator provides vision assisted tools that leverage both RGB information and Depth information. Toggle between Color and Disparity to switch from a color-based selection and a disparity-based selection.

Modify Edge

Grows or shrinks the selection by a set number of pixels (between 1px and 10px).

Fit Accuracy

Adjust the allowed error between the mask and the generated curve. Higher values mean more vertices and a closer fit.


Brush Tool

The Brush Tool is a "painting" way to create a pixel mask.

To activate the Brush Tool, click on the Brush Icon on the Toolbar or press B. Click and drag in the artboard to draw brush strokes. Finish a custom shape by clicking the Done button or by pressing the enter key. The mask will snap to the edges of your stroke.

Brush Size

Adjust the brush size with the Brush Size slider in the toolbar or with [ and ].

Add & Subtract Mode

Choose between positive and negative strokes — the mask is continually updated based on new positive/negative strokes. Positive strokes provide information that we want to retain or add in the selection. Negative strokes provide information that we want to remove from the selection.

Switch between positive and negative strokes by holding ALT.

    Add directions on how to make multiple mask shapes on a surface. In the right column, MASK area, you can add a path.

    Hi,

    1. How do you use the pen tool to do shapes that have a hole? Like a doughnut.

    2. How do you delete a mask point? I really need to do this because I almost always want to edit the mask once I published it.

    3. How do you combine multiple masks? Let's say, I have 2 separate masks for 2 separate objects but I want to project as one surface in a given slide.

    4. How do you delete bezier handles so the point / anchor behaves exactly like before the bezier handle was added?

    Thanks.
