Detailed Description

Sample code to install a pass-through Image Filter into Houdini

These filters can be used in:

Karma Image Filters
The AI Denoise COP
The idenoise application For example, after the code is build, the filters should appear when running idenoise -l.

To make this example, you can run:

hcustom -i ~/houdini/dso/img_filter TIL_NullFilter.C

To test the filter, you can try:

% idenoise -d null_filter --options '{"verbose":1,"test":3.2}"' Mandril.pic x.exr

% idenoise -d null_filter --normal N --extra_aovs P --options '{"verbose":1}"' Snail.pic x.exr
