# Qt Quick 3D - Antialiasing Example

Demonstrates the antialiasing modes in Qt Quick 3D.

The Antialiasing example demonstrates how to control antialiasing in Qt Quick 3D. It shows a simple scene that exhibits antialiasing artifacts. There is a simple Qt Quick user interface that allows choosing between the antialiasing types, and setting the options that control them.

#### The test scene

This example shows a simple scene that contains a sphere and two rotated cubes. The scene is set up so that it clearly shows jagged edges when antialiasing is not enabled.

#### Controlling antialiasing

Antialiasing is controlled by the SceneEnvironment object. The values are set based on the selection made in the user interface.

The antialiasing mode can be set to `NoAA` to disable antialiasing, or to one of the following:

- `SSAA` for supersample antialiasing
- `MSAA` for multisample antialiasing
- `ProgressiveAA` for progressive antialiasing

The antialiasing quality can be set to `Medium`, `High`, or `VeryHigh`.

In addition, temporal antialiasing can be enabled independently. The temporal antialiasing mode can be set to one of the following:

- `TAADefault` for basic temporal antialiasing
- `TAAMotionVector` for higher-quality temporal antialiasing which uses motion vectors

          environment: SceneEnvironment {
              id: sceneEnvironment
              clearColor: "#002b36"
              backgroundMode: SceneEnvironment.Color

              antialiasingMode: modeButton1.checked ? SceneEnvironment.NoAA : modeButton2.checked
                                                      ? SceneEnvironment.SSAA : modeButton3.checked
                                                        ? SceneEnvironment.MSAA : SceneEnvironment.ProgressiveAA

              antialiasingQuality: qualityButton1.checked ? SceneEnvironment.Medium : qualityButton2.checked
                                                            ? SceneEnvironment.High : SceneEnvironment.VeryHigh
              temporalAAEnabled: temporalModeButton.checked
              temporalAAStrength: temporalStrengthSlider.value
              temporalAAMode: temporalModeDefault.checked ? SceneEnvironment.TAADefault : SceneEnvironment.TAAMotionVector
          }
