Constructor
new Texture3DNode( value : Data3DTexture, uvNode : Node.<(vec2|vec3)>, levelNode : Node.<int> )
Constructs a new 3D texture node.
| value |
The 3D texture. |
| uvNode |
The uv node. Default is |
| levelNode |
The level node. Default is |
Properties
.isTexture3DNode : boolean (readonly)
This flag can be used for type testing.
Default is true.
Methods
.generateOffset( builder : NodeBuilder, offsetNode : Node ) : string
Generates the offset code snippet.
| builder |
The current node builder. |
| offsetNode |
The offset node to generate code for. |
- Overrides: TextureNode#generateOffset
- Returns: The generated code snippet.
.generateUV( builder : NodeBuilder, uvNode : Node ) : string
Generates the uv code snippet.
| builder |
The current node builder. |
| uvNode |
The uv node to generate code for. |
- Overrides: TextureNode#generateUV
- Returns: The generated code snippet.
.getDefaultUV() : Node.<vec3>
Returns a default uv node which is in context of 3D textures a three-dimensional uv node.
- Overrides: TextureNode#getDefaultUV
- Returns: The default uv node.
.getInputType( builder : NodeBuilder ) : string
Overwrites the default implementation to return a fixed value 'texture3D'.
| builder |
The current node builder. |
- Overrides: TextureNode#getInputType
- Returns: The input type.
.normal( uvNode : Node.<vec3> ) : Node.<vec3>
Computes the normal for the given uv. These texture coordiantes represent a position inside the 3D texture. Unlike geometric normals, this normal represents a slope or gradient of scalar data inside the 3D texture.
| uvNode |
The uv node that defines a position in the 3D texture. |
- Returns: The normal representing the slope/gradient in the data.
.setUpdateMatrix( value : boolean )
Overwritten with an empty implementation since the updateMatrix flag is ignored
for 3D textures. The uv transformation matrix is not applied to 3D textures.
| value |
The update toggle. |
- Overrides: TextureNode#setUpdateMatrix
