As you drag with Magic Brush, your selection stroke automatically extends to include parts of the image that have continuity in the RGB information.
How to create a surface with Magic Wand
- To activate Magic Brush, click on the Magic Brush Icon on the Toolbar or press Y.
- In the options bar, specify any of the following:
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 to 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 paint 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.
- In the artboard, paint over colors and regions that you want to include in the Surface.
- Click the Create Surface button.
- In the options bar, make any of the following adjustments:
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.
- 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.
