Documentation / scene / MorphBlurNode

Class: MorphBlurNode

Defined in: libs/scene/src/utility/blueprint/material/texture.ts:1750

Morph + blur node

Remarks

Applies channel morphology and Gaussian blur in a single node. The node short-circuits internally so that when one radius is zero it falls back to the corresponding single-stage path instead of always paying for the full combined cost.

Inputs:

• texture: source mask texture
• coord: UV coordinates, defaults to vertex UV when disconnected
• morphRadius: positive expands, negative shrinks, zero disables morph
• blurRadius: blur radius in texel units, zero disables blur
• channelMask: channel selector mask, defaults to R

Output:

• Result: scalar sampled value

Extends

• BaseGraphNode

toString()

toString(): string

Defined in: libs/scene/src/utility/blueprint/material/texture.ts:1973

Generates a string representation of the node

Returns

string

Empty string by default

Remarks

Subclasses should override this to return valid shader code or a meaningful description of the node's operation.

Overrides

BaseGraphNode.toString

---

validate()

protected validate(): string

Defined in: libs/scene/src/utility/blueprint/material/texture.ts:1976

Validates the node's current state

Returns

string

Error message string, or empty string if valid

Remarks

Default implementation checks if all required inputs are connected. Subclasses can override to add custom validation logic like:

• Type compatibility checking
• Value range validation
• Configuration validation

Example

protected validate(): string {
  const baseError = super.validate();
  if (baseError) return baseError;

  // Custom validation
  const type1 = this._inputs[0].inputNode?.getOutputType(0);
  const type2 = this._inputs[1].inputNode?.getOutputType(0);
  if (type1 !== type2) {
    return 'Input types must match';
  }

  return '';
}

Overrides

BaseGraphNode.validate

---

getType()

protected getType(): string

Defined in: libs/scene/src/utility/blueprint/material/texture.ts:2013

Gets the type name for a specific output slot

Returns

string

The type name (e.g., 'float', 'vec3', 'mat4')

Remarks

Must be implemented by subclasses to define type resolution logic. The type may depend on connected input types.

Example

protected getType(_id?: number): string {
  // Return type based on first input
  const inputType = this._inputs[0]?.inputNode?.getOutputType(this._inputs[0].inputId ?? 0);
  return inputType ?? 'float';
}

Overrides

BaseGraphNode.getType

---

getOutputType()

getOutputType(id): string

Defined in: libs/scene/src/utility/blueprint/node.ts:376

Gets the output type for a specific output slot

Parameters

id

number

The output slot ID

Returns

string

The type name of the output

Remarks

Default implementation delegates to the abstract getType() method. Can be overridden for more complex type logic.

Inherited from

BaseGraphNode.getOutputType

---

check()

check(): void

Defined in: libs/scene/src/utility/blueprint/node.ts:413

Validates the node and updates error state

Returns

void

Remarks

Calls the validate() method and stores the result in _error. Emits a 'changed' event if the error state changes.

Inherited from

BaseGraphNode.check

---

reset()

reset(): void

Defined in: libs/scene/src/utility/blueprint/node.ts:422

Clears the error state

Returns

void

Remarks

Sets _error to an empty string.

Inherited from

BaseGraphNode.reset

---

setInput(id, node, inputId): void

Defined in: libs/scene/src/utility/blueprint/node.ts:443

Connects an input slot to another node's output

Parameters

id

number

The input slot ID to connect

node

BaseGraphNode

The source node to connect from

inputId

Returns

void

Throws

Example

const addNode = new AddNode();
const constantNode = new ConstantNode(5.0);

// Connect constantNode's output 0 to addNode's input 0
addNode.setInput(0, constantNode, 0);

Inherited from

BaseGraphNode.setInput
