[Smtk-developers] Color Support Part 2

[Bob Obara]

Hi All,

As hinted in my previous email, we are going support inherited color support.  For example if you want to have all your surfaces colored white and your edges colored blue - you will be able to select the edges node in the model tree and set its color to blue - as a result, all edges will be by default blue.  If you then select edge 3 and set it to yellow you will have all your edges but edge 3 blue and edge 3 will be yellow - if you then change the edges node color to say red - all edges but edge 3 will be red and edge 3 will remain yellow.

The issue this brings up is how to easily identify to the user that a model entity  has an explicit color or is inheriting the color from the model tree.

Below are two possible solutions:

1. Change the shape of the “color swatch" associated with the model entity - in this case a rounded color swatch indicates that the entity is using an inherited color (in this case white) and a square shape indicates that it has an explicit color 

2. keep the shape of the color swatch the same and use a hash pattern  to indicate the color is inherited - a variation of this could be is to have just the icon (no border) to indicate that the color is inherited.

Comments?
