##### Examples:

    const style = new Cesium3DTileStyle({
        show : '(regExp("^Chest").test(${County})) && (${YearBuilt} >= 1970)'
    });
    style.show.evaluate(feature); // returns true or false depending on the feature's properties

    const style = new Cesium.Cesium3DTileStyle();
    // Override show expression with a custom function
    style.show = {
        evaluate : function(feature) {
            return true;
        }
    };

    const style = new Cesium.Cesium3DTileStyle();
    // Override show expression with a boolean
    style.show = true;
    };

    const style = new Cesium.Cesium3DTileStyle();
    // Override show expression with a string
    style.show = '${Height} > 0';
    };

    const style = new Cesium.Cesium3DTileStyle();
    // Override show expression with a condition
    style.show = {
        conditions: [
            ['${height} > 2', 'false'],
            ['true', 'true']
        ];
    };

#### readonly style : object
engine/Source/Scene/Cesium3DTileStyle.js 174

Gets the object defining the style using the 3D Tiles Styling language.

Default Value: `{}`

#### translucencyByDistance : StyleExpression
engine/Source/Scene/Cesium3DTileStyle.js 869

Gets or sets the `StyleExpression` object used to evaluate the style's `translucencyByDistance` property. Alternatively a string or object defining a vec4 style can be used. The getter will return the internal `Expression` or `ConditionsExpression`, which may differ from the value provided to the setter.

The expression must return a `Cartesian4`.

This expression is only applicable to point features in a Vector tile.

##### Example:

    const style = new Cesium.Cesium3DTileStyle();
    // Override translucencyByDistance expression with a string
    style.translucencyByDistance = 'vec4(1.5e2, 1.0, 1.5e7, 0.2)';
    style.translucencyByDistance.evaluate(feature); // returns a Cartesian4

##### Experimental

This feature is using part of the 3D Tiles spec that is not final and is subject to change without Cesium's standard deprecation policy.

#### verticalOrigin : StyleExpression
engine/Source/Scene/Cesium3DTileStyle.js 1191

Gets or sets the `StyleExpression` object used to evaluate the style's `verticalOrigin` property. Alternatively a string or object defining a number style can be used. The getter will return the internal `Expression` or `ConditionsExpression`, which may differ from the value provided to the setter.

The expression must return a `VerticalOrigin`.

This expression is only applicable to point features in a Vector tile.

##### Examples:

    const style = new Cesium3DTileStyle({
        verticalOrigin : VerticalOrigin.TOP
    });
    style.verticalOrigin.evaluate(feature); // returns a VerticalOrigin

    const style = new Cesium.Cesium3DTileStyle();
    // Override verticalOrigin expression with a custom function
    style.verticalOrigin = {
        evaluate : function(feature) {
            return VerticalOrigin.CENTER;
        }
    };

##### Experimental

This feature is using part of the 3D Tiles spec that is not final and is subject to change without Cesium's standard deprecation policy.
