  • Next week

Week 109 : 4th - 10th Feb

  • Info

The "Edit mode wireframe drawing" refactor has been finished. It now draws the same on all platform using a geometry shader to draw arbitrary thick lines and use analytic AA instead of MSAA.

We also changed the active face color hint to be a mix between the active color and the face color. This is because drawing a contour line around the active polygon was not working well with the new drawing method.

  • Next week

Refactor object mode wires drawing as usual fix bugs.

Week 108 : 28th - 3rd Feb

  • Info

I've added support to transparency for solid mode. It is supported in object and material color mode. Transparency can be changed by tweaking the alpha of the main color. It uses the same Order Independant Transparency as the Xray mode.

I also started working on the edit wire refactor but it is not finalized. As it is a crucial feature I decided to not commit the changes yet. Changes should arrive in master this week.

Week 105 : 7th - 13th Jan

  • Info

This week was focused at finishing the UVedit and selection batch refactor started before vacation.

Edit mesh selection has been changed a bit and should behave more consistently when selecting vertices in mixed vertex and edge mode.
