ViewportDepthNode

This node offers a collection of features in context of the depth logic in the fragment shader. Depending on ViewportDepthNode#scope, it can be used to define a depth value for the current fragment or for depth evaluation purposes.

Constructor

new ViewportDepthNode( scope : 'depth' | 'depthBase' | 'linearDepth', valueNode : Node )

Constructs a new viewport depth node.

scope

The node's scope.

valueNode

The value node.

Default is null.

Properties

.isViewportDepthNode : boolean (readonly)

This flag can be used for type testing.

Default is true.

.scope : 'depth' | 'depthBase' | 'linearDepth'

The node behaves differently depending on which scope is selected.

• ViewportDepthNode.DEPTH_BASE: Allows to define a value for the current fragment's depth.
• ViewportDepthNode.DEPTH: Represents the depth value for the current fragment (valueNode is ignored).
• ViewportDepthNode.LINEAR_DEPTH: Represents the linear (orthographic) depth value of the current fragment. If a valueNode is set, the scope can be used to convert perspective depth data to linear data.

.valueNode : Node

Can be used to define a custom depth value. The property is ignored in the ViewportDepthNode.DEPTH scope.

Default is null.
