A surface is a mapping preset that can be shared between all the layers of a same canvas. Each layer of a canvas can be bind to a surface and its mapping will be updated according to the surface.
With this, many layer can easily be mapped to the same place. If the mapping on stage changes, all the binded layers can have their mapping updated just by updating the surface.
Surfaces can be edited in the
Output window by clicking on the
Mapping button :
Then in the
Surface tab :
On the right of the tab, you can find a list of all the surfaces of the selected canvas :
Use on the
- buttons to add/remove surfaces. You can reorder surfaces by dragging-and-dropping them in the list. So a surface can be rendered above another one :
If you need to reuse these surfaces in another Millumin project, they can be imported or exported to a SVG file. Use the
… button to do so.
Lastly, such surfaces have a few properties :
Click on the colored square on the left to change it :
Edit it by double clicking the label :
Can be a triangle or a quadrangle. Clicking on the blue shape on the right to change it :
The surface’s position can be changed by dragging its shape in the workspace view, or dragging its corners :
Edit with numbers
The surface’s mapping can be edited with numbers by double-clicking a corner :
While dragging a surface or one of its mapping corner, the snapping can be activated by pressing the
SHIFT key of the keyboard.
If a surface’s mapping corner snap the mapping corner of another surface they will be attached together. The two corners will now move altogether as a same corner. They can be detached by clicking on them while holding the
SHIFT key pressed.
Display only contours
To easily the mapping in some case, use the box
display only contours option :
Binding a Layer to a Surface
When a layer is selected, the surface options can be found in the
properties-view in the
The surface property has 4 options :
- (no mapping)
It is the default option. The layer has no mapping applied to it. Selecting it when the layer has a mapping will remove the mapping and unbind it from its surface.
- (free mapping)
This option is set when the layer has a mapping applied to it without a surface. Selecting it while the layer is bind to surface will unbind the surface but keep its mapping.
- A surface’s name
By selecting a surface by its name will bind the layer to this surface. The mapping of the layer will be the one of the surface. And by updating the surface mapping, the layer’s one will follow.
- Edit Surfaces…
Selecting this option will open the surface setup.
Binding a layer
Clicking on one of the yellow surface in the surface view, under the surface property, will bind the layer to this surface. The surface will appear orange in the view :
Layers with unbinded mapping will appear as grey in the surface view :
Creating a new surface
By clicking on an unbinded mapping in the surface view will allow to convert it to a new surface :
