            what is the meaning of "map" from map function?
            Asked 2021-Jun-15 at 11:06

            I'm happy to use "map function" in python for parallelized calculations. such as below.



            Answered 2021-Jun-14 at 20:26

            "Map" is also a synonym for "function" in the mathematical sense: something that sends an input to an output. You should be able to find it in any English dictionary. It can also be used as a verb for the process of transformation: "map each element to its square".

            The word "map" for a geographic drawing is related, in that it also "maps" each point of the real terrain to a point on the paper map, or vice versa.

            It is not an acronym.

            How to keep Opengl Scatter Instances size unchanged?
            Asked 2021-Jun-14 at 21:58

            Here is my question, i will list them to make it clear:

            1. I am writing a program drawing squares in 2D using instancing.
            2. My camera direction is (0,0,-1), camera up is (0,1,0), camera position is (0,0,3), and the camera position changes when i press some keys.
            3. What I want is that, when I zoom in (the camera moves closer to the square), the square's size(in the screen) won't change. So in my shader:


            Answered 2021-Jun-14 at 21:58

            Sounds like you use a perspective projection, and the formula you use in steps 1 and 2 won't work because VP * vec4 will in the general case result in a vec4(x,y,z,w) with the w value != 1, and adding a vec4(a,b,0,0) to that will just get you vec3( (x+a)/w, (y+b)/w, z) after the perspective divide, while you seem to want vec3(x/w + a, y/w +b, z). So the correct approach is to scale a and b by w and add that before the divde: vec4(x+a*w, y+b*w, z, w).

            Note that when you move your camera closer to the geometry, the effective w value will approach towards zero, so (x+a)/w will be a greater than x/w + a, resulting in your geometry getting bigger.

            glBitmap: bitmap size issue
            Asked 2021-Jun-14 at 10:38

            I have a doubt trying to understand and use glBitmap function. I started from this example and trying to draw a 40x40 "bitmap" and avoiding a situation like this I tried this:

            40 x 40 is 1600 bits -> so I need 200 bytes of info (1600/8)



            Answered 2021-Jun-14 at 10:38

            You missed to set the alignment. By default OpenGL assumes that the start of each row of the raster is aligned to 4 bytes. This is because the GL_UNPACK_ALIGNMENT parameter by default is 4. Each row in the raster has 5 bytes (40 / 8 = 5). Therefore you need to change the alignment to 1:

            JavaFX Canvas.setScaleX/Y(2) not scaling to twice the size
            Asked 2021-Jun-13 at 13:23

            Maybe I'm misunderstanding something basic, but I'm experimenting with JavaFX and am baffled why scaling a Canvas (using .setScaleX/Y) with value of 2 doesn't result in canvas with two times bigger width/height.

            The relevant code is this: (I'm not using any .fxml at this point)



            Answered 2021-Jun-13 at 11:18

            You've already added canvas to the pane, try to apply .setScaleX/Y before pane.getChildren().add(canvas).

            Group toggle buttons in vb.net winform
            Asked 2021-Jun-13 at 13:04

            I'm working on a theme for a little app where I need to place some toggle buttons. Like showed in many place this site, I've done it using a checkbox and changing the apparance by a custom onpaint event ,(basically a draw it like a button). Then I realize that checkbox not grouping like radio buttons, so I've done the same with a radio buttons, but even if I place 2 of them in a groupbox, I still can "checked" them both; which is the best way to do that? here sample code that I used to make some test:



            Answered 2021-Jun-13 at 13:04

            Yes you can imitate the behavior of a group of RadioButton controls in a container. Just find the controls of the same type in the Parent.Controls collection and uncheck them when the current instance is checked.


            Add this method to MyToggleButton class.

            Answered 2021-Jun-13 at 09:00

            The mask simply isn't big enough to cover the shape. You've not set any height/width for it so you'll get the defaults of 120%. That's not enough in this case for the width.

            Increasing the viewBox width corrects things as the mask width is a percentage of that viewBox width so you're indirectly increasing the mask width.

            threebox "projectToWorld" returns values exceeding canvas, how do I fix this? (with sample code)
            Asked 2021-Jun-12 at 22:39

            I recently found out there is a very handy method in three-box for placing three.js objects on the map which is "projectToworld".

            While trying to place my three.js objects using the method, I realized that the Vector3 the method returns are really huge and not on the map.

            According to the documentation of threebox, it says


            tb.projectToWorld(lnglat) : THREE.Vector3

            Calculate the corresponding THREE.Vector3 for a given lnglat. It's inverse method is tb.unprojectFromWorld.

            So I decided to use this method to locate my animated object in three js canvas. But what the methods returns are really huge.

            So as I expected, these values don't place the three objects on the map and all the objects disappeared because they presumably are placed at very distant locations.

            How do I fix this issue?

            I made a minimal code to demonstrate this issue as below.

            1. instantiating map


            Answered 2021-Jun-12 at 22:39

            It's strange that no one could answer this question. So I finally figured out how to make it by myself.

            The solution is in the following link.

            The primary reason was that mapbox plots things not based on its vector configuration. It renders things through its matrix as follows.

            var m = new THREE.Matrix4().fromArray(matrix); var l = new THREE.Matrix4().makeTranslation(modelTransform.translateX, modelTransform.translateY, modelTransform.translateZ) .scale(new THREE.Vector3(modelTransform.scale, -modelTransform.scale, modelTransform.scale))

            Animate a UIBezierPath hexagon like UIActivityIndicatorview
            Asked 2021-Jun-12 at 18:48

            I'm trying to achieve exactly the same animation shown below


            and my output using UIBezierPath and CABasicAnimation is this below.

            Here is my LoaderView code



            Answered 2021-Jun-03 at 13:46

            The problem is - the code is rendering the complete path - start-to-end each time and start is same for all animations.

            The idea for loaders is - start point has to change after each animation - something like -

            1. Start at angle 0
            2. Go up to angle 45 /// or 60 whatever you want this to be
            3. Change start angle to next logical step - say 30
            4. Then render up to 75 /// or 90 depending on what you chose previously

            In this arrangement, you have to keep drawing a certain portion of the shape by changing start point continuously.

            In practice, achieving a smooth transition between different start point values may prove out to be difficult than it seems. You can find an example here - https://github.com/SVProgressHUD/SVProgressHUD/blob/master/SVProgressHUD/SVIndefiniteAnimatedView.m#L48-L102


            The link I shared above has all the hints in it. This library uses an image as a mask and then rotate that continuously. Mask shape can be anything you like - you already have code for that.

            You just need to create an image that's appropriate for your animation. See what their asset looks like

            and AFTER masking what their animation looks like -
