Image distortion
This pose will cover some distortion nodes.
Displace
Displace node shift the pixel around according to the brightness (or red and green channel) of the displace map.
Inputs |
Type |
Description |
Surface in |
Surface |
Image input. |
Displace map |
Surface |
Displace strength map. |
Position |
Float[2] |
Base displacement. |
Strength |
Float |
Displacement multiplication. |
Mid value |
Float |
Middle value to map from black to white. |
Use RG as vector |
Boolean |
Use red and green to displace in XY axis. |
Iterate |
Boolean |

Outputs |
Type |
Description |
Surface out |
Surface |
Image output. |
Texture remap
Texture remap use red and green channel to remap X,Y position of the image.
Inputs |

Mesh warp
Mesh warp node is a node in the transform section which allow you to warp an image using control points.
Mesh generation has to be activate manually by clicking on "Generate" button in inspector panel.
