Methods

e = e && e.destroy();

Throws

• DeveloperError : 此對象已被銷毀，即調用destroy（）。

See:

• Primitive#isDestroyed

Parameters:

var attributes = primitive.getGeometryInstanceAttributes('an id');
attributes.color = bmgl.ColorGeometryInstanceAttribute.toValue(bmgl.Color.AQUA);
attributes.show = bmgl.ShowGeometryInstanceAttribute.toValue(true);
attributes.distanceDisplayCondition = bmgl.DistanceDisplayConditionGeometryInstanceAttribute.toValue(100.0, 10000.0);
attributes.offset = bmgl.OffsetGeometryInstanceAttribute.toValue(Cartesian3.IDENTITY);

Throws

• DeveloperError : 必須在調用GetGeometryInstanceAttributes之前調用Update。

See:

• Primitive#destroy

Throws

• DeveloperError : 所有實例幾何必須具有相同的PrimitiveType。
• DeveloperError : 外觀和材料有一個統一的名稱。
• DeveloperError : Primitive.ModelMatrix僅在3D模式下受支持。
• RuntimeError : 需要頂點紋理獲取支持來渲染具有每個實例屬性的基本體。頂點紋理圖像單位的最大數目必須大于零。
