            Are OpenGL ordered as viewed by an internal or external viewer?
            Asked 2021-May-23 at 07:38

            I have written a WebGL program which displays a rotating cube. The indices are in counter-clockwise order as viewed from the outside. However, when I decide to enable cull faces, the faces that I understand to be "front" are culled, and the cube appears to be hollowed-out. I can fix this issue by telling WebGL to cull "front" faces instead.

            I declared the cube's vertex positions, texture coordinates, and indices as follows: image or text.

            My question is: am I supposed to declare points in counter-clockwise order as viewed from within the shape? If not, why are the indices I am using backwards?

            This program (which is already the minimum reproducible example) is below.

            No they are not. The indices of the 1st triangle are 0, 1, 2 and the vertices are (-1, 1, -1), (-1, -1, -1), (1, -1, -1).

            how to fill the hollow lines opencv

            As you can see that the black lines become hollow. I have tried erosion and dilation, but if I do them many times, the 2 entrances will be closed(meaning become connected line or closed contour).

            How could I make those lines solid like the below image while keep the 2 entrances not affected?

            I picked up @fmw42's post as answer as his answer is the most detailed one. It doesn't answer my question but points out the correct way to process maze which is my ultimate goal. I like his approach of answering questions, firstly tells you what each step should do so that you have a clear idea about how to do the task, then provide the full code example from beginning to end. Very helpful.

            Due to the limitation of SOF, I can only pick up one answer. If multiple answers are allowed, I would also pick up Shamshirsaz.Navid's answer. His answer not only points to the correct direction to solve the issue, but also the explanation with visualization really works well for me~! I guess it works equally well for all people who are trying to understand why each line of code is needed. Also he follows up my questions in comments, this makes the SOF a bit interactive :)

            The Threshold track bar in Ann Zen's answer is also a very useful tip for people to quickly find out a optimal value.

            Canny is an edge detector. It detects the lines along which color changes. A line in your input image has two such transitions, one on each side. Therefore you see two parallel lines on each side of a line in the image. This answer of mine explains the difference between edges and lines.

            So, you shouldn’t be using an edge detector to detect lines in an image.

            If a simple threshold doesn't properly binarize this image, try using a local threshold ("adaptive threshold" in OpenCV). Another thing that works well for images like these is applying a top hat filter (for this image, it would be a closing(img) - img), where the structuring element is adjusted to the width of the lines you want to find. This will result in an image that is easy to threshold and will preserve all lines thinner than the structuring element.

            To filter the Character array is a bit tricky because an empty string isn't actually a character.

            You need to group name elements by last.

            Since you're using XSLT 1.0 you'd need to use the Muenchian Method.

            This means creating a key (matching name and using last).

            Then you need to iterate over each of the first name elements that contain the matching key (this is the part of Muenchian grouping that you can either use generate-id() or count()).

            By using the value of last you can create the Crockett and Baseball elements.

            Then iterate over all of the name elements in the matching key. These all become the candidate elements.

            All that's left is to process the first elements (don't process last), strip the type attribute of the first elements, and change the first elements to last when the type attribute equals "informal".

            Give it a shot yourself, but here's an example just in case you get stuck...

            There are a couple of problems here.

            1. As others have pointed out, \n creates a new line,
              like so. \t on the other hand, creates an indent, like so. For your purposes, \t is what you want.

            2. In your squares function, you only print two ***s. Instead, print 3.

            3. Since squares already prints one line, you only need a single for loop going up to 2. The conventional way to do this is int i = 0; i < 2.

            Below is the full corrected code (I fixed the indentation, rebracketed, and added a main method):
