Diary During Summer Vacation 11

This week I worked on adding the editing feature to the knot rendering engine. The first step is to add the ability to show editing balls on the control points on the cubic central line. Press S key is to toggle showing the editing balls. Next, a ball should be able to change its color when being selected. I reckon a world coordinator with X, Y, Z axes should appear as well to smartly response to the user's intention when an editing ball is selected. As shown in the log picture, these two features have been added. It was quite a busy week: Working 9 hours a day, coding, study, attending an English test, feeling exhausted.
