quaternion | brief introduction to the quaternions and its applications | Graphics library

I am trying to Instantiate a tree prefab based on transforms (specifically the position and rotation) that are loaded from a firebase database.

The problem here is that the foreach loop only iterates one time even though there are a total of 4 children in snapshot.Children, so I am confused as to why it only runs once.

This is the method

i made a function in unity that takes a Binode - and making it into a2d tree, but here the problem: my so called idea to display the tree is this:

make a recursive function, and every time the level will go up by 1, and it will also send the function a bool(is the right or is the left of the old node) and then if its true it will get the root of the tree and - the y by level * 55, then it will either x = level * 55, if it right, and if its left the x = level * -55.

now the problome is lets say i have a tree that has 3 levels, then if i will put a right node to the left tree it will just put it were the most right node is and it will overlap, kinda hard to explain in text but i hope you understand.

heres the repository: git

code:

I'm really struggling here and I can't get it right, not even knowing why. I'm using p5.js in WEBGL mode, I want to compute the position of on point rotated on the 3 axes around the origin in order to follow the translation and the rotation given to object through p5.js, translation and rotatation on X axis, Y axis and Z axis.

The fact is that drawing a sphere in 3d space, withing p5.js, is obtained by translating and rotating, since the sphere is created at the center in the origin, and there is no internal model giving the 3d-coordinates.

After hours of wandering through some math too high for my knowledge, I understood that the rotation over 3-axis is not as simple as I thought, and I ended up using Quaternion.js. But I'm still not able to match the visual position of the sphere in the 3d world with the coordinates I have computed out of the original point on the 2d-plane (150, 0, [0]).

For example, here the sphere is rotated on 3 axis. At the beginning the coordinates are good (if I ignore the fact that Z is negated) but at certain point it gets completely out of sync. The computed position of the sphere seems to be completely unrelated:

It's really hours that I'm trying to solve this issue, with no result, what did I miss?

Here it follows my code:

I'm trying to have an object oscillate between -45 and 45 degrees, and the following is the code I am using. Note that direction is initialized to 1, zRotation to 360, and speed to 100. This works perfectly fine. However, when I change speed to 1000, the object does a complete 360 rotation before continuing to oscillate correctly. I'm confused why that happens.

This is my code(inside the Update method):

I'm trying to make the coroutine spawn one object at a time every 0.2 seconds, but when I run the coroutine, it spawns multiple objects at once without any delay. How can I fix this and achieve the desired result?

My code:

In the game I'm making, I clone a Ball object whenever a "split ball" power-up is acquired. Everything works as intended except the TrailRenderer material. The Ball prefab has a default material used for TrailRenderer in the beginning. This, however, changes when the ball hits an object controlled by the player (which is called a "bumper"). The material changes work perfectly on collision. Here is the shortened script for the Ball object:

Scenario

I'm using unity c# to re-invent a google-earth like experience as a project. New tiles are asynchronously loaded in from the web while a user pans the camera around the globe. So far I'm able to load in all the TMS tiles based on their x & y coordinates and zoom level. Currently I'm using tile x,y to try and figure out where the tile should appear on my earth "sphere" and it's becoming quite tedious, I assume because of the differences between Euler angles and quaternions.

• I'm using the angle of Camera.main to figure out which tiles should be viewed at any moment (seems to be working fine)
• I have to load / unload tiles for memory management as level 10 can receive over 1 million 512x512 tiles
• I'm trying to turn a downloaded tile's x,y coordinates (2d) into a 3d position & rotation

Question

Using just the TMS coordinates of my tile (0,0 - 63,63) how can I calculate the tile's xyz "earth" position as well as its xyz rotation?

Extra

• in the attached screenshot I'm at zoom level 4 (64 tiles)
• y axis 0 is the bottom of the globe while y axis 15 is the top
• I'm mostly using Mathf.Sin and Mathf.Cos to figure out position & rotation so far

I've figured out how to get the tile position correct. Now I'm stuck on the correct rotation of the tiles.

The code that helped me the most was found with a question about generating a sphere in python.

I modified to the code to look like so:

Mac Big Sur C++ OpenGL attempting to learn quaternions from a tutorial. The gtx headers are under usr/local/include/glm. Can anyone figure out what is wrong with my header includes or header search path? Thanks.

Minimum reproducible code that fails for this issue:

I'm trying to build a controller for a unity gameobject to move it similary to a normel quadrotor drone. So the drone should be able to ascend and descend by mobing the left stick up and down, turn around by moving the left stick sidewards and move horizontally by using the right stick.

I tried implementing it with the unity inputSystem, but unfortunately, it doesn't really work the way it is supposed to. Movements are mostly not smooth and the rotation causes the horizonzal movement to move in wrong directions.

Here is my code:
