如何在 Google 灯丝中为 Android 设置背景颜色?

How to set background color in Google Filament for Android?

我正在学习灯丝教程:https://medium.com/@philiprideout/getting-started-with-filament-on-android-d10b16f0ec67

如何将背景颜色设置为白色?

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        surfaceView = SurfaceView(this).apply {
            setContentView(this)
        }
        choreographer = Choreographer.getInstance()
        modelViewer = ModelViewer(surfaceView)
        surfaceView.setOnTouchListener(modelViewer)

        loadGlb("DamagedHelmet")

        modelViewer.scene.skybox = Skybox.Builder().build(modelViewer.engine)
        loadEnvironment("venetian_crossroads_2k")

    }

我试过在 SurfaceView 上设置背景颜色,但没用。

目前看起来是这样的(好像默认是黑色的):

我明白了。我需要设置天空盒颜色。

例如,这会将颜色设置为红色。

modelViewer.view.blendMode = com.google.android.filament.View.BlendMode.OPAQUE
modelViewer.scene.skybox = Skybox.Builder().color(0.81f, 0f, 0f, 0f).build(modelViewer.engine)
