QUESTION
I am trying to make a function to genereate bezier curves and save each x,y position in a matrix. The row number indicates the number of objects I will set the coordinates to and the number of columns is the number of points (coordinates) generated by the function. I am trying to generate two curves for two objects using the same function but the new values generated by the function the second time are not saved in the vector and I don't know why.
This is my code
...ANSWER
Answered 2021-May-15 at 13:41The new values are saved to the vector, but you didn't read the new values and instead of that you are reading the values firstly added twice.
The new values are added to the vector without clearing the vector, so the new values will be added after the values that are already added.
If you want to read new values, you can store the offset to read before adding elements and use the information to read new values.
QUESTION
I am working on a flask app where I get the error above when I try to link my js file in my html page.
However, when I include the js logic under tag in the HTML file itself, I don't see the error and the page is rendered as expected
Approach used that causes error.
JS: stored in /static/js/alv.js
...ANSWER
Answered 2020-Oct-23 at 04:05This problem arises because you can't use Jinja templating in a file which is not rendered by flask but is a static file. In this question several methods of using flask variables in external js is explained. Pass parameter with Python Flask in external Javascript
Explanation of Problem
When you use {%%} or {{}} this code can't be understood by html or browser so when the flask renders it, it convert those logic and variables into html. But for this flask needs to know that you are rendering a file containing Jinja tags. We do this when we call render_template() and pass the html file in it. But in case of js files we don't tell flask that we are rendering a js file because in most cases it is used for client side coding so flask need not know that. But in some cases like yours you have to use flask variables in js. Unfortunately there is no direct way to do this so we have to do this in a hack(ish) way as you have seen in that thread.
QUESTION
I'm trying to create a PyPi package for my graphics framework Goopylib (https://github.com/BhavyeMathur/goopylib), and it is working for the most part.
All the package files are being created when I try to pip install my package - the only problem is that these package files are not being created in a directory of their own, rather just in the site-packages directory.
In these 2 screenshots, you can see that package files like the 'math' folder or the GraphWin.py file are being created in the site-packages folder and not a folder of their own.
Here what I would want my code to be organized like with the goopylib folder being inside the site-packages folder:

QUESTION
I want to draw a slightly bent line using bezier curve.
This is the bezier curve function:
function bezierCurve(controlPoint1, controlPoint2, line) { }
I don't know how to set control points to achieve a slightly bent line for any line.
I tried to find the perpendicular point of this line:
...ANSWER
Answered 2020-Mar-12 at 20:53The function
function bezierCurve(controlPoint1, controlPoint2, line) { }
Suggest that the curve is a cubic bezier (two control points) the function you give looks like its only finding a point mid way and offset some fixed amount. you will need more control over where the point is in relationship to the line.
Perpendicular offset from line.The following function will give you a little more control letting you specifty where along the line you want the point and how far that point should be from the line.
The argument along and dist are fractions of a line such the along = 0.5 is halfway and dist = 0.2 is 1/5th the length of the line away. dist > 0 and the point is offset to the right of the line dist < 0 and the offset is to the left (Y axis pointing down)

QUESTION
I am trying to create a line chart that presents score level from 1-100.
Line is static and needs to be curved
but the dot on the chart is dynamic value and by that it changes its location along the existing line.
First I was thinking to add additional data that represents only the dot itself, but Y(height) is unknown.
Second attempt led me to create a second line that crosses / intersects the first one in hope of finding intersection point and making it a dot.
Unfortunately, I couldn't find a way to locate intersection.

QUESTION
Using Chart.js with zoom/pan enabled, I am trying to write a function to export only what is visible on the canvas to CSV.
But I cannot figure out how to get only the visible datapoints after the user zooms/pans.
I know I can just look at myChart.data.datasets but that would fetch all the points in the chart, not just the currently visible ones.
ANSWER
Answered 2019-Nov-02 at 12:46The toBase64Image function does not what you want, it just gets the data URL from the canvas.
