Nadir Patch

Complex

Description

This node provides functionality to patch over the central ground point (nadir) of a spherically mapped image. It can be used to hide or “clone out” an ugly nadir, or visible camera or tripod. It works like a Clone Patch, but with adjustments for spherically mapped images. The user selects a point elsewhere in the image, that is the cloned and blended in at the nadir. No other external inputs are required other than a single HDRI to process, but an external mask can be used as alpha for the patch effect.

effect can be quickly checked and validated with Nadir Extract.

Inputs

• Input: Color Input
• Mask Input: Grayscale Input
  Optional mask slot used for masking the patch. Function like an alpha.

Parameters

• Enable: False/True
  Enable or disable patching effect.

• Show Frames Helper: False/True
  Show or hide the helper lines, for debug purposes.

• Frame Thickness: 0.0 - 1.0
  Thickness of helper lines.

• Patch Scale: 0.0 - 1.0
  Global, uniform scale of patch. Affects both source and target.

• Patch Size: 0.0 - 1.0
  Non-uniform size of patch.

• Patch Rotation: 0.0 - 1.0
  Rotation of the patch. Affects source and target.

• Patch Alpha: Smooth Square, Gaussian, Mask Input
  Set what alpha is used to blend the patch with the background.

• Patch Hardness: 0.0 - 1.0
  Set hardness/contrast of alpha.

• Source Rotation Offset: 0.0 - 1.0
  Rotation only for source of the patch.

• Position Coordinates

  • Source Position:
