            How to combine two polar charts?
            Asked 2022-Mar-29 at 17:28

            I founded a very interesting code that allows to combine two differents charts.

            I would like to do the same with two polar charts to permit multiple scale, but there is no renderer as line and shape or bar. Is there nevertheless a way to do that ?

            The aim is to plot to series with big dynamic difference like distance & site of laser shoots for each azimuth, something like that:

            While I'm not aware of any support for nesting multiple polar plots with differing scales, jfreechart does support zooming, as described here. Absent a domain axis, zooming is limited to the range axis. Because the zooming controls may be counterintuitive in this context, the variation below adds plot-specific controls: The getZoomOutAction() simply invokes the chart panel's restoreAutoBounds() method, like this, while the getZoomInAction() extends the range by 50%, like this.

            Intermittent errors with Bitmask Collisions
            Asked 2022-Feb-23 at 04:47

            I'm making a 2D scrolling shooter in Swift with SpriteKit. I've set up SKPhysicsBody and using bitmasks for collisions. I keep getting intermittent errors, where the collisions will work fine and then stop working. The error I get is Fatal error: Unexpectedly found nil while unwrapping an Optional value. I don't understand why I get nil value sometimes, when it gets a value other times. I have a few different sprites in the game and after testing a lot to see if there is any difference in the collisions, I can't seem to find the problem. For example, a few play throughs and I shoot an asteroid with the laser and it will work fine. The next day the exact same thing crashes the game. Another example asteroid hits player head on and works fine, asteroid hits player from the side crashes game but next day could work fine. I don't know if the problem is with the way I've set the PhysicsBody for each sprite, as I've tried changing that and still had problems, or have I got the SKPhysicsContact set up all wrong. Any help would be mostly appreciated, Thank you.

            Callback functions in ROS ? How to properly update them?
            Asked 2022-Jan-14 at 20:51

            So I make robot, which should get data from laser sensor and then move until some distance and stops.

            But I find problem in callback functions. Is there somewhere better explanation how to update variables with callback properly ? I had same problem with python and there I found out that time.sleep(0.2) let the class to update properly. Even this is little bit magic for me. Because I was thinking that in python this works automatically because separated threading.

            In c++ I know that the basic is using spinOnce() and spin(). This works how it should in normal non-object-oriented case. But in the class again I found out that the class is not updated properly. Why is this a case ? I can not find why the callback function is not working properly. I could see if it was the case by print full range from reading, but it never happens. I have ros::spinOnce() and I think I have correctly member functions. Can someone please help me ? And help me to understand ?

            I found the problem. Basically with callbacks. You have to be sure, that the publisher catches up. So before you call the spinOnce() which checks if it is something there. You have to call some sort of wait function. ros::rate/ros::Duration and wait. Then when you call spinOnce(). You will have new incoming data, which the callback function can read.

            Your issue is because you're immediately calling move after finishing the constructor; where you setup the subscriber. This means there is relatively 0 chance that any data has been received. Instead, you should be validating that you have enough data before trying to slice the list and other operations on the data; because these operations assume you do have data. Something like this:

            THREE.JS & Reality Capture - Rotation issue photogrammetry reference camera's in a 3D space
            Asked 2022-Jan-03 at 14:57

            Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!

            Introduction

            Currently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?

            Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.

            Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:

            The challenge

            As a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).

            Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).

            Answered 2022-Jan-02 at 22:26

            At first glance, I see three possibilities:

            • It's hard to see where the issue is without showing how you're using the createCamera() method. You could be swapping pitch with heading or something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.

            • Secondly, do you know in what order the heading, pitch, roll measurements were taken by your sensor? That will affect the way in which you initiate your THREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be 'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.

            • Finally, you have to think "What does heading: 0 mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards -Z axis, but your sensor might have it pointing towards +Z, or +X, etc.

            Edit:

            I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.

            Increasing variables that are in use in pygame
            Asked 2021-Dec-25 at 09:30

            I am coding a space invaders game in pygame, and wanted to make it so that when the player reaches 50 points, the game increases the number of invaders from 6 to 10. In the game, the enemies respawn near the top half of the screen immediately after dying. The game functions perfectly normally until you reach 50 points, at which it immediately crashes. How do I make it so that the variable storing the number of enemies (num_of_enemies) increases, while the game is still running?

            In the code I have put here, I removed my attempt to change the num_of_enemies variable, but fyi, I placed it just above "pygame.display.update()". my crappy attempt to resolve the issue boiled down to:

            if score_value >= 50: num_of_enemies += 10

            I have also tried this code while assigning num_of_enemies a global value, but it simply defects the game, and messes up again.

            To write into endpoint 0, you'll need the device.ctrl_transfer(bmRequestType, bmRequest, wValue, wIndex, packet) instead of endpoint.write(packet).

            The bmRequestType, bmRequest, wValue and wIndex correspond to the same elements in the USB control request. The fact that the Windows software uses hidapi suggests the control transfers are done according to the USB HID specification.

            This answer here on Stack Overflow describes how to make USB HID set/get operations on plain PyUSB.

            But since the source code you're porting uses hidapi, using the Python hidapi interface might make the process more straightforward. This question has an example of using hidapi in Python, and the answers also talk about alternatives.
