The Footprint Focus feature available in Release 23, enables you to change the footprint’s focus distance in wysiwyg’s Shaded Views. The result is more creative freedom, and an even closer-to- real-life simulation; it allows you to make the focus of the footprint “hard” or “soft”. (In previous versions of wysiwyg, the footprint focus has always been “hard”).

As you can see in the R23 Examples, the footprints can now be soft providing a truer visualization of real world situations.
R23 Footprint Example 3
Footprint Focus is available for conventional fixtures (in CAD mode through the Fixture Properties) and for automated fixtures (in Design mode through the new Footprint Designer Tool). It involves two basic steps:
1. Enable the Footprint Focus feature in the Shaded view.
2. Adjust the Footprint Focus of your fixtures.
As shown below, the focusing method differs between conventional and automated fixtures: conventionals are focused in CAD mode, while automated fixtures are focused in Design mode.
Note: In the next wysiwyg release, the Footprint Focus feature will be extended to function in Live Mode like all other Designer tools.
Enabling Footprint Focus in the Shaded View
Note: Custom Shaded View options are applicable only to the Shaded View in which they are set. For example, if you enable Footprint Focus in CAD mode on the Quad tab, you must do so again for the Shaded View in Design mode. Therefore, if you are adjusting Footprint Focus and see no variations, ensure that you have enabled the Footprint Focus feature in the particular Shaded View in which you are working.
1. Right-click in the Shaded view, and select View Options.
2. Click the Lighting tab.
3. Ensure that the Beam Type is set to Enhanced. (Note that this feature cannot be used with wysiwyg’s Classic Beams.)
4. Under Footprint Focus, click to select the Enable checkbox.
5. Click OK.
Adjusting Footprint Focus for Conventional Fixtures
As with other conventional fixture attributes (Pan/Tilt/Spin, Colour, Gobo, and so on), you must set Footprint Focus in CAD mode, as shown below:
1. Select the (conventional) fixture.
2. Right-click and select Properties.
3. Click the Fixture tab.
4. On the General tab, under Footprint Settings, click Enable Footprint Focus(Conventionals only).
5. Adjust the Focus Distance manually by using the slider, or by entering an actual distance in the Focus Distance box.
Note: Alternatively, you can wait to adjust the fixture’s Focus Distance until you have enabled Footprint Focus (by completing this procedure). In so doing, you will be able to adjust the Focus Distance on the fly, seeing the effect “live”. Simply select the fixture in a Wireframe View, right-click and choose Footprint Focus. (Its recommended that you leave the Focus Lines option enabled when doing so.) Then, adjust the focus distance by pressing and holding the Up / Down arrow keys on your keyboard. When finished, right-click and select Finish Footprint Focus.
6. Adjust the remaining footprint settings, as required:
• The Min and Max Focus Range values represent the minimum and maximum distance at whcih the distance at which the fixture may be focused. The The default values are suitable for most applications; it is recommended that you leave the default values unless the fixtures are very far away from the object upon which they are focused.
• The Sync to Focus Position option is enabled only if a focus position has been assigned to the fixture. Click this option to ensure perfect focus at the coordinate of the Focus Position assigned to the fixture. When this option is enabled, the Focus Distance controls (both the slider and the manual entry field) are disabled.
• The Focus Lines option is enabled by default and helps when adjusting Focus interactively. When enabled, a line is drawn (both in Wireframe and Shaded view) from the fixture to the focus target. The length of this line is equal to the Min and Max Focus Range values.
7. When you have finished setting the footprint options, click OK.
In the next two screenshots, note how the footprint appears differently on the wall, based on whether the focus is set to the mannequin or the wall. You can also see the handy Focus Lines.
Adjusting Footprint Focus for Automated Fixtures
As with other automated fixture attributes (Pan/Tilt, Gobo, Zoom, and so on), you must set Footprint Focus in Design mode. Before doing so, however, ensure that you enable Footprint Focus in the Shaded view’s View Options, as described in the procedure above, Enabling Footprint Focus in the Shaded View.
1. Select the (automated) fixture.
2. Use the Intensity Tool to turn it on.
3. Make any other necessary adjustments to the fix ture, such as selecting a colour, a gobo, and so on.
4. From the Design menu, select Footprint Tool.
5. Click the Enable checkbox.
6. Use the wheel (or the arrows) to adjust the footprint focus, or enter a value manually in the box provided.
7. To set the focus to the minimum or maximum Focus Range values, click the Min or Max button. (As with conventional fixtures, you can modify these values on the Properties page for the selected fixture.)
8. When the Focus Lines option is selected, as with conventional fixtures, a yellow line will appear between the fixture and the focus target.
9. The Sync to Focus Position option is enabled only if a focus position has been assigned to the fixture. Click this option to ensure perfect focus at the coordinate of the Focus Position assigned to the fixture. When this option is enabled the wheel in the Footprint Tool and all surrounding controls are disabled.
10. When you have finished setting the necessary options, select the next fixture and repeat.
In the next two screenshots, note how the footprint appears differently on the wall, based on whether focus is set to the mannequin or the wall. You can also see the handy Focus Lines.
Simulate Diffusion or Frost
You can use Footprint Focus not only to throw footprints/ beams out of focus, but also to simulate some basic frost or diffusion filters. Simply adjust the focus to blur the footprint, thereby creating your frost effect! Naturally, not all such filters can be simulated, especially those that modify the shape of the beam of the fixture (for example, silk frost); actual simulation for such filters will be implemented in the near future.
Using Fixture Point of View to Help with Footprint Focusing (Conventional Fixtures only)
The improved Fixture Point of View popup in R23 can be very helpful when adjusting the footprint focus because it shows you what the fixture is “seeing”, enabling you to adjust the focus accordingly. To enable Fixture Point of View:
1. In the Shaded View (or Shaded quadrant of the Quad tab), right-click and select Open in Popup Frame.
2. Once the popup window appears, right-click within it and select Popup Options.
3. On the General tab, in the Camera section, select POV of selected fixture from theCamera drop- down box.
4. Click OK.
5. Select a fixture. Note how the image in the popup changes to reveal what the fixture is “seeing”. Adjust the Footprint Focus as necessary (as described in the procedure above).
Using Footprint Focus More Efficiently
To use this feature for many (or all) of the fixtures in your plot, once your fixture placement is complete or nearing completion, it is recommended that you enable Footprint Focus for all fixtures simultaneously. Once Footprint Focus is enabled, you may use the interactive method described above to make the necessary adjustments.
1. In CAD, select all conventional fixtures in your plot.
2. Right-click and select Properties.
3. Click the Fixture tab.
4. On the General tab, click Enable Footprint Focus (Conventionals only).
5. Click OK.
6. Deselect the fixtures.
7. Select the first fixture that you want to adjust and use the interactive method described above (at the end of the Adjusting Footprint Focus for Conventional Fixtures procedure). When finished, select the next fixture and repeat.
