Script comes pre-installed in the Unofficial trueSpace Updates - https://www.united3dartists.com/forum/viewforum.php?f=55

Installation:

1. install the persistent base if not already installed
2. drag the node into the link editor
3. delete the node from the scene after install is complete

• Angle Tolerance - the maximum angle for comparison of normals
• Select Connected - option for the normals selection tool, if checked then the selection will be limited to neighboring mesh faces
• Object Mode - quadrangulate a selection of objects
• Quadrify By Normals - uses the triangle normals to control the quadrify process. This option is not used when Object Mode is active.

Selection:

1. select a face
2. press the button and all faces facing in the same direction will be selected
3. if Select Connected then only the faces near the initial selection will be considered.

TODO: rewrite the explanations below for May 24 changes

Quadrify - Object Mode

1. choose Object Mode from the panel
2. Select the object(s) to be quadrified
3. Set tolerance - low values will be more accurate, but will run much more slowly
   high values are less accurate, but will run faster
4. If run with high tolerance, fix any problems: Quadrify, Object Mode unchecked and run the tool on point edit selections

Quadrify - recommended

1. Quadrify By Normals off
2. Make a selection and run the quadrify tool - this runs very quickly
3. If good result, stop here
4. Press undo 3 times
5. Quadrify By Normals on
6. Make a selection and run the quadrify tool - this may take a while to finish
7. The result may be a little better, but no worse than before

Quadrify - not by normals ( the default )

1. Uncheck the Quadrify By Normals option
2. Select faces or triangles
3. Run the tool

Quadrify - by normals

1. Check the Quadrify By Normals option
2. mesh does not need to be in point edit mode to run
3. set the Angle Tolerance to a low value
4. run the tool
5. if triangles still exists steadily increase the tolerance between runs to get a clean mesh

Notes:

• The first face of the selection is used for the comparison normal
• Angle Tolerance can have values between 0.1 degrees and 90 degrees.
• Quadrify will run more quickly and less accurately with larger tolerances.
• Quadrify by normals can be limited to a selection, instead of running on the entire mesh.
• Quadrify by normals may not give you the quads you are expecting to get. Small tolerance and selection based limiting can help with this.
• Tools will not run on workspace NURBS objects, lights or cameras.

May 24, 2021

• fixed incorrect math and logic for normals comparisons
• new object mode with multi-object selection support
• new panels from trueBlue

February 28, 2021

• fixed extremely slow quadrify by normals - now just runs slowly
• add new quadrify without using the normals - much faster, works in most cases
• better completion feedback for the quadrify by normals
• changed initial triangle selection in quadrify to be the middle of the selection order - slightly better results in quad by normal
