# Qt Quick 3D - Order Independent Transparency Example

Demonstrates the order independent transparency in Qt Quick 3D.

The OIT example demonstrates how to enable order-independent transparency in Qt Quick 3D. It has multiple examples using the feature in different ways.

#### The examples

Particles example shows the use of OIT with transparent particles. Instancing example shows the use of OIT with models rendered using instancing. Blend Value Correctness example demonstrates the sorting problem with transparent objects and lets one enable OIT to fix the issue.

#### Controlling OIT

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

The oit method is by default set to `OITNone` to disable the feature, or one can set it to `OITWeightedBlended` to enable OIT.

             environment: SceneEnvironment {
                 clearColor: "#000000"
                 backgroundMode: SceneEnvironment.Color
                 antialiasingMode: AppSettings.antialiasingMode
                 antialiasingQuality: AppSettings.antialiasingQuality
                 oitMethod: SceneEnvironment.OITWeightedBlended
             }
