Qt Quick 3D - 抗锯齿范例

演示 Qt Quick 3D 中的抗锯齿模式。

The 抗锯齿 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.

测试场景

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.

控制抗锯齿

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 ，或 VeryHigh .

此外， temporal antialiasing can be enabled independently.

     environment: SceneEnvironment {
         id: sceneEnvironment
         clearColor: "#f0f0f0"
         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
     }
