Development Status

On this page I will update the development status of the Silhouette Operator. Keeping track of all the bugs, features and ideas.

Bugs

These are the bugs I can identify at the moment. Currently bugs often overlap and produce the same resulting failure due to different reasons. This list will most likely grow quicker than i can resolve most of the issues.

Priority

General

done

 looptris aren't recalculated properly or caches aren't updated

done

 Clamp out of bound values

to do

 find and resolve crashers

in progress 30%

 memory deallocation/free (mutex fix might have solved it)

Add Mode

done

 Inverse tube bug. (happens when the start point of a silhouette is in a tube segment.)

to do

 Normal issues with tubes.

Subtract Mode

to do

 Inverted Normals when primary ring is ccw

to do

 Mismatching ringlayout bugs

to do

 Flooding bugs

to do

 Clumped uneven fillets (Triangulation fails)

Priority

General

on hold

 u resolution scales with depth.

Add Mode

to do

 Double vertices in generated shapes.

to do

 Small end caps create undesirable nooks.

Subtract Mode

Features

This is a collection of features which are either mandatory, planned or ideas.

Mandatory

These features need to be implemented before the tool can be used. Without them the tool might be usable but doesn't fit into the workflow and is not very useful.

in progress 10%

 Undo/Redo

to do

 Draw on Geometry

When enabled drawing on the surface takes surface normal as draw plane and start point as anchor instead of the 3D cursor.

to do

 Adaptive Depth

The depth is currently not very intuitive to set. Blender units are not an intuitive measurement. One idea is an aspect ration depth setting. For example: "Set the depth 2x the width."

to do

 Object scaling and view scale influence silhouette size confusingly

Planned

These features are planned and will be implemented after the mandatory features. They are not crucial to the tool but very useful.

to do

 Clipping Mode

When enabled smoothness is set to 0% and depth is set to the target geometry thickness.

to do

 Spacing and other stroke options

Ideas

The Ideas are features which could be added to the silhouette operator but aren't fully developed concepts yet.

on hold

 Multistage drawing: You can see a mockup below (maximise). You have a virtual plane on which you can modify the already drawn strokes, as well as changing the tool settings after drawing.

on hold

 Manipulators after generating the silhouette. (When finishing a stroke the last silhouette can be dragged, rotated etc to rearrange)

on hold

 Two stroke system (Draw the footprint first and then extrude with a second stroke.)
