Constructor
new ScreenNode( scope : 'coordinate' | 'viewport' | 'size' | 'uv' )
Constructs a new screen node.
| scope |
The node's scope. |
Properties
.isViewportNode : boolean (readonly)
This flag can be used for type testing.
Default is true.
.scope : 'coordinate' | 'viewport' | 'size' | 'uv'
The node represents different metric depending on which scope is selected.
ScreenNode.COORDINATE: Window-relative coordinates of the current fragment according to WebGPU standards.ScreenNode.VIEWPORT: The current viewport defined as a four-dimensional vector.ScreenNode.SIZE: The dimensions of the current bound framebuffer.ScreenNode.UV: Normalized coordinates.
Methods
.generateNodeType() : 'vec2' | 'vec4'
This method is overwritten since the node type depends on the selected scope.
- Overrides: Node#generateNodeType
- Returns: The node type.
.update( frame : NodeFrame )
ScreenNode implements Node#update to retrieve viewport and size information
from the current renderer.
| frame |
A reference to the current node frame. |
- Overrides: Node#update
