kandi X-RAY | torus Summary
Torus is an open source project for distributed storage coordinated through. Torus provides a resource pool and basic file primitives from a set of daemons running atop multiple nodes. These primitives are made consistent by being append-only and coordinated by [etcd]. From these primitives, a Torus server can support multiple types of volumes, the semantics of which can be broken into subprojects. It ships with a simple block-device volume plugin, but is extensible to more. Sharding is done via a consistent hash function, controlled in the simple case by a hash ring algorithm, but fully extensible to arbitrary maps, rack-awareness, and other nice features. The project name comes from this: a hash 'ring' plus a 'volume' is a torus.

QUESTION
Is there a way in Julia to constrain the argument type of a function type? Let's say I have a function f = p::Int -> sqrt(p) and I need to pass this function to other functions, is there a way to specify that these other functions take in functions which themselves take in Int, something like my_func(f::Function{Int}) = ....
I am working on a raymarching implementation which uses functions to encode geometry. To combine two geometric objects, I need to take the minimum of their respective functions. Right now, I have this

the #num is just a name given to un-named variables.

I tried to import OrbitControls but it isnt working.
I imported three.js and then tried impoting OrbitControls but it isnt working
I imported three.js in the body of the html with this command
script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/104/three.js"
NOTE: I do have a scene and a camera and a renderer but i cant post this post with them here
ANSWER
Answered 2022-Feb-13 at 14:27You're using the jsm version of the OrbitControls, which means that you need a module for the Javascript file. Change:
to
That should do the trick.

I'm trying to install react-twitter-embed on my react app. I have tried deleting and reinstalling my node_modules folder and clearing my npm cache. I've tried upgrading my node and npm to the latest version as well.
Here's the error I'm getting:

I'm drawing some static geometry (a sphere, a cube, etc.) together with some dynamic geometry (a rotating torus.)
I can see that there is a problem because specular lighting on the torus is static and the torus is rendered dark when the rotation angle changes...
I'm targeting OpenGL 2.1 (desktop), OpenGL ES2 (mobile) and WebGL1 (web). Here is a gist with the full code. There is also a WebGL demo.
The framework used is chronotext-cross. It provides a level of abstraction above GL. It should be straightforward to understand. In any case I can provide pointers, as the author.

QUESTION
Recently I started working with matplotlib. Can you help how I can rotate(spin) animation a torus around Oz? I tried to change the values of x,y,z in the update function, but this changes the location of the torus, not its rotation.
...ANSWER
Answered 2021-Nov-27 at 18:30One way to do this is to just change the value of the azim argument of the ax.view_init function in your update function. You can for instance add the line ax.view_init(azim=360*num/100, elev=10). That way, the point of view rotates around the z-axis at every frame.

QUESTION
I have been working on a personal project of mine using Three JS as my main 3d object renderer and I wanted to randomly generate spheres at random x, y, and z coordinates with a specified range, I was able to do so, but now I need each of these randomly generated objects to have a randomly placed rotation speed along its x y and z from a range of 0.005 to -0.005. But no clue how to approach this and any help would be greatly appreciated, he is my random generation code, and also the code to animate 3d objects I have already dealt with:
...ANSWER
Answered 2021-Oct-13 at 02:21You could store the random value of rotation on creation and animate it on each render.
QUESTION
Here is a Hopf torus created in Python with PyVista:
...ANSWER
Answered 2021-Oct-05 at 12:44As a side note, at least to me it's clearer to compute the magnitude of the points yourself and set those as scalars (rather than relying on the magnitude of vector data as scalars for colour mapping, even though this is supported and valid).
What you're missing is just a choice of colourmap. The default, just like with matplotlib, is viridis. Instead it seems you want jet (although I'd recommend against this; perceptually uniform colourmaps are preferable in most cases for data visualization):
QUESTION
ANSWER
Answered 2021-Oct-05 at 12:37I think what's going on here is that there's no connectivity information where the two ends of your structured grid meet. One way to fix this is to turn your grid into a PolyData using the extract_geometry() method, and then using clean with a larger tolerance. This will force pyvista to realise that there's a seam in the mesh where points are doubled, causing the points to be merged and the seam closed:
