QUESTION
WHAT I'M DOING
I'm rendering circular points with varying vertex colors using a fragment shader. I in essence want the points to act as more performant spheres that are antialiased when zoomed all the way in.
PROBLEM
It works in one direction (see left photo), but the other direction has white corners (see right photo). How do I get rid of the white corners?
WHAT I TRIED
- If the points were all the same color, I could turn off depthTest and it would just work. However, the points must be varying colors. Turning off the depthTest with varying colors makes it look like a wormhole.
- I tried alphaTest to no avail. I did get alphaTest to work with textures instead of a custom fragment shader (png of a circle on transparent background), but it looked blurry when zoomed in sufficiently.
- I did notice that the colors of the corners was equivalent to whatever I passed into renderer.setClearColor.
- I've played around with blending options, but I'm not familiar enough with blending yet to understand what I'm doing.

1 - Move your Helloer class to inside ca.company package. Spring classpath scanning won't work if Helloer is at the same level as ca.company and you will get some error like below:

Answered 2017-Mar-23 at 23:50pip defaults to installing Python packages to a system directory (such as /usr/local/lib/python3.4). This requires root access.
--user makes pip install packages in your home directory instead, which doesn't require any special privileges.

Answered 2020-May-04 at 16:51The problem is not caused by the abstract class but because the QObjects do not have childItems, unlike the QQuickItem that does have that property.
The same thing you could see if you use QtObject:

QUESTION
The year is 2102 and today is the day of ZCO. This year there are N contests and the starting and ending times of each contest is known to you. You have to participate in exactly one of these contests. Different contests may overlap. The duration of different contests might be different.
There is only one examination centre. There is a wormhole V that transports you from your house to the examination centre and another wormhole W that transports you from the examination centre back to your house. Obviously, transportation through a wormhole does not take any time; it is instantaneous. But the wormholes can be used at only certain fixed times, and these are known to you.
So, you use a V wormhole to reach the exam centre, possibly wait for some time before the next contest begins, take part in the contest, possibly wait for some more time and then use a W wormhole to return back home. If you leave through a V wormhole at time t1 and come back through a W wormhole at time t2, then the total time you have spent is (t2 - t1 + 1). Your aim is to spend as little time as possible overall while ensuring that you take part in one of the contests.
You can reach the centre exactly at the starting time of the contest, if possible. And you can leave the examination centre the very second the contest ends, if possible. You can assume that you will always be able to attend at least one contest–that is, there will always be a contest such that there is a V wormhole before it and a W wormhole after it.
For instance, suppose there are 3 contests with (start,end) times (15,21), (5,10), and (7,25), respectively. Suppose the V wormhole is available at times 4, 14, 25, 2 and the W wormhole is available at times 13 and 21. In this case, you can leave by the V wormhole at time 14, take part in the contest from time 15 to 21, and then use the W wormhole at time 21 to get back home. Therefore the time you have spent is (21 - 14 + 1) = 8. You can check that you cannot do better than this.
Input:The first line contains 3 space separated integers N, X, and Y, where N is the number of contests, X is the number of time instances when wormhole V can be used and Y is the number of time instances when wormhole W can be used. The next N lines describe each contest. Each of these N lines contains two space separated integers S and E, where S is the starting time of the particular contest and E is the ending time of that contest, with S < E. The next line contains X space separated integers which are the time instances when the wormhole V can be used. The next line contains Y space separated integers which are the time instances when the wormhole W can be used.
Output:Print a single line that contains a single integer, the minimum time needed to be spent to take part in a contest.
