Add-on functionality
To enable sliding of two images in Blender – in the Image Editor area, select the first image in the area header in the usual way. Select the second image in the “ICS” add-on panel. Click the “Compare Images” button to activate the sliding of the two selected images.
Drag the boundary by holding and moving the mouse cursor.
You can switch between horizontal or vertical delimiters in the add-on panel.
To exit the sliding mode – click the right mouse button or pressing the “Esc” key.
In addition to simple images, the add-on allows you to compare the “Render Result” and the output from the compositing “Viewer Node”.
Open the Compositor area and add a “Viewer” node (shift + a – Output – Viewer). Connect it to the node tree at the required place. To make it recalculate faster, activate the “Backdrop” checkbox in the Compositor area header.
In the Image Editor area, in the header select the render result – “Render Result”, and in the add-on panel select the “Viewer Node”. Click the “Compare Images” button to activate the slider.
When changing the compositor nodes, simply click the “Compare Images” button again to update the slider according to the compositor changes.
Image Comparison Slider also works in the 3D Viewport area.
You can use it for comparing Render result with the project scene or for verification meshes with the reference images.
