# AffectViewingBox

Influence of objects on the ViewingBox of a scene

## Value Summary

 Inherited FALSE, or TRUE

## Description

AffectViewingBox determines whether the ViewingBox of an object should be taken into account for the total ViewingBox of the graphical scene.

Usually, the visible area/volume of a graphical scene is automatically chosen as the smallest box containing all objects of the scene. Objects with AffectViewingBox = FALSE are ignored in the computation of this box.

## Examples

### Example 1

We plot the sine and the exponential function in one scene:

```plot(plot::Function2d(sin(x), x = -PI..PI),
plot::Function2d(exp(x), x = -PI..PI))```

The exponential function dominates the sine. We set AffectViewingBox = FALSE for exp. Now, only the sine function determines the visible area and exp is only visible where it is in the ViewingBox of the sine function:

```plot(plot::Function2d(sin(x), x = -PI..PI),
plot::Function2d(exp(x), x = -PI..PI,
AffectViewingBox = FALSE))```
