QUESTION
First I knew that Three.js does not have official support for occlusion culling. However, I thought it's possible to do occlusion culling in an offscreen canvas and copy the result back to my Three.js WebGLCanvas.
Basically, I want to transform this demo to a Three.JS demo. I use Three.js to create everything, and in a synced offscreen canvas, I test occlusion culling against each bounding box. If any bounding box is occluded, I turn off the visibility of that sphere in the main canvas. Those are what I did in this snippet. but I don't know why it failed to occlude any sphere.
I think a possible issue might be coming from calculating the ModelViewProjection matrix of the bounding box, but I don't see anything wrong. Could somebody please help?
...ANSWER
Answered 2021-Feb-01 at 03:07At a minimum, these are the issues I found.
you need to write to the depth buffer (otherwise how would anything occlude?)
so remove
gl.depthMask(false)you need to
gl.flushtheOffscreenCanvasbecause being offscreen, one is not automatically added for you. I found this out by using a normal canvas and adding it to the page. I also turned on drawing by commenting outgl.colorMask(false, false, false, false)just to double check that your boxes are drawn correctly. I noticed that when I got something kind of working it behaved differently when I switched back to the offscreen canvas. I found the same different behavior if I didn't add the normal canvas to the page. Adding in thegl.flushfixed the different behavior.depthSortwas not workingI checked this by changing the shader to use a color and I passed in
i / NUM_SPHERESas the color which made it clear they were not being sorted. The issue was this

QUESTION
I will try to describe my problem as best in English first starting from the top:
This starts with a structure named 't' which there needs to be 6 of (this never changes), which contains some simple variables - but also needs to contain an array of structures called 'p' which there needs to be 4 of per 't' object. 'p' will contain some further simple variables followed by a further array of structures called 'f' which will then finally just contain some simple variables.
See code below for how I would attempt this problem:
...ANSWER
Answered 2020-Jul-19 at 14:07The problem here is of the order of declaration/definitions.
You need to at least have the type declared before the compiler can understand and use it (which then would be an "incomplete type", since it's not yet defined. These incomplete type can only be used in certain cases, like declaring pointers to them etc). In your case however it needs to be defined since it is ODR used.
QUESTION
I can do fr"" and rf"" in python.
As far as I understand, here the order may be important, but I would like to understand if this is so?
And if that is, then I want to see an example, which will show possible problems.
It would also be interesting to hear about order issues, including the remaining u and b.
For example, fbr, what about it?
ANSWER
Answered 2020-Jun-21 at 22:48The order of f and r doesn't matter. Here's what I found from the docs:
'f' may be combined with 'r' or 'R', in either order, to produce raw f-string literals. 'f' may not be combined with 'b': this PEP does not propose to add binary f-strings. 'f' may not be combined with 'u'.

QUESTION
I am making an online game in node.js and trying to save a game replay on my game's server. I am using flatbuffers to serialize data for client-server communication and I thought it would be cool to save my game's state frame by frame in the file.
I created the following table in my .fbr file
ANSWER
Answered 2020-Jan-20 at 19:43The best way to do this is to make sure each individual FlatBuffer is a "size prefixed buffer" (it has a 32-bit size ahead of the actual buffer), which in JS you can create by calling this instead of the usual finish function: https://github.com/google/flatbuffers/blob/6da1cf79d90eb242e7da5318241d42279a3df3ba/js/flatbuffers.js#L715
Then you write these buffers one after the other into an open file. When reading, because the buffers start with a size, you can process them one by one. I don't see any helper functions for that in JS, so you may have to do this yourself: read 4 bytes to find out the size, then read size bytes, repeat.
