Buffer node
|
|
~~~~~~~~~~~
|
|
|
|
The **Buffer** node samples its input into a texture of a given resolution and
|
|
outputs the result.
|
|
|
|
Buffers can be used either as inputs of complex nodes (to limit the combined
|
|
shader's complexity), or to create a cheap blur/pixelization effect (by using the
|
|
LOD output). Note that many complex transforms that are provided in the nodes library
|
|
already include buffers where necessary.

Inputs
|
|
++++++
|
|
|
|
The **Buffer** node has an input that will be stored into its buffer image.
|
|
|
|
Outputs
|
|
+++++++
|
|
|
|
The **Buffer** node has 2 outputs:
|
|
|
|
* the first output provides the image
|
|
|
|
* the second output generates a given mipmap of the image
|
|
|
|
Parameters
|
|
++++++++++
|
|
|
|
The **Buffer** node has two parameters:
|
|
|
|
* the *texture resolution*
|
|
|
|
* the *mipmap level* of its second output
