How can I draw a line starting from one point in the direction of the angle between the points seen here? This is what I have for calculating the angle double angle1 = atan2(point_1_y – point_2_y, point_3_x – point_2_x); double angle2 = atan2(point_1_y – point_3_y, point_3_x – point_2_x); double result = angle1 – angle2; Source: ..

So I am taking picture using the following code https://superkogito.github.io/blog/CaptureScreenUsingGdiplus.html#id4 I only modified it so that it can take particular window handle (HWND) that I am interested in. It works flawlessly unless I pass the handle to Chrome-based app (this includes any Electron app etc.) Does anyone have a clue what might be the issue ..
I have device and want to calculate its tilt (theta) angle using 3 axis accelerometer? For the reference, I attached an image which showing how the device position in hand and need to calculate theta showing in the image. enter image description here SO, anyone can give me the formula to calculate the theta angle ..
I want to implement the ear-clipping algorithm, and I found a code which just does that. The problem is, that it sometimes goes into infinite loop, because the function which is determining if three point in the polygon is convex or not, returns with an incorrect value. Here’s the code: bool isConvex(Point* active) { Point* ..
From picture: I have to calculate alpha, defined as the angle between the lines that connects two points and the y-axis, with a range 0 to 180 in the direction that can be seen in the image, and with a range of 0 to -180 in the opposite (arrow pointing from current starting point to ..
I have two different configurations of a project and I wish to link one against one against windows’ standard opengl32.lib and the other against Angle. The trouble is, both of these libraries implement the OpenGL interface and I see no way of choosing between them other than removing one library from vcpkg. It seems to ..
I’m making a game for my cpp class. I have a player which I want to emit a particle beam out the front following the path the player will follow (for aiming). In order to make the particles shoot out in front of the player they have to be moving at a greater speed than ..
how to compute the yaw of the some object in 3d space? I know the coordinates my current position(start vector) and my target (end vector). If I explained it oddly here is the thing: for example, im facing north so my current yaw im facing is 0 degrees or 360, and object is located on ..
I tried to write a program where a vector is calculated that bisects the angle between two lines that share one common point. For that I’ve come up with some code (Since this it not the only thing I’m trying to do the code is a bit longer but I’ve boiled down the problem to ..
I’m trying to draw a dialog box with sfml and I’m using a VertexArray with quads. I want it to have a corner with 2 points like in the image. Could someone help me with the math on how to get the length of A? Or maybe someone has a suggestion to do it in ..
