Css Problem Overview

tl;dr: I would like to create an actual 3d sphere with CSS - not just an illusion

Note: some of the snippet examples are not responsive. Please use full screen.

With pure CSS you can create and animate a 3d cube like so:

#cube-wrapper {
  position: absolute;
  left: 50%;
  top: 50%;
  perspective: 1500px;
}

.cube {
  position: relative;
  transform-style: preserve-3d;
  animation-name: rotate;
  animation-duration: 30s;
  animation-timing-function: linear;
  animation-iteration-count: infinite;
}

@keyframes rotate {
  0% {
    transform: rotate3d(0, 0, 0, 0);
  }
  100% {
    transform: rotate3d(0, 1, 0, 360deg);
    ;
  }
}

.face {
  position: absolute;
  width: 200px;
  height: 200px;
  border: solid green 3px;
}

#front_face {
  transform: translateX(-100px) translateY(-100px) translateZ(100px);
  background: rgba(255, 0, 0, 0.5);
}

#back_face {
  transform: translateX(-100px) translateY(-100px) translateZ(-100px);
  background: rgba(255, 0, 255, 0.5);
}

#right_face {
  transform: translateY(-100px) rotateY(90deg);
  background: rgba(255, 255, 0, 0.5);
}

#left_face {
  transform: translateY(-100px) translateX(-200px) rotateY(90deg);
  background: rgba(0, 255, 0, 0.5);
}

#top_face {
  transform: translateX(-100px) translateY(-200px) rotateX(90deg);
  background: rgba(0, 255, 255, 0.5);
}

#bottom_face {
  transform: translateX(-100px) rotateX(90deg);
  background: rgba(255, 255, 255, 0.5);
}

.cube {
  transform: rotateX(90deg) rotateY(90deg);
}


<div id="cube-wrapper">
  <div class="cube">
    <div id="front_face" class="face"></div>
    <div id="right_face" class="face"></div>
    <div id="back_face" class="face"></div>
    <div id="left_face" class="face"></div>
    <div id="top_face" class="face"></div>
    <div id="bottom_face" class="face"></div>
  </div>
</div>

I want to create and animate a 3d sphere in the same manner.

So... the first idea I get is to use border-radius and...well... it doesn't work.

#cube-wrapper {
  position: absolute;
  left: 50%;
  top: 50%;
  perspective: 1500px;
}

.cube {
  position: relative;
  transform-style: preserve-3d;
  animation-name: rotate;
  animation-duration: 30s;
  animation-timing-function: linear;
  animation-iteration-count: infinite;
}

@keyframes rotate {
  0% {
    transform: rotate3d(0, 0, 0, 0);
  }
  100% {
    transform: rotate3d(0, 1, 0, 360deg);
   
    ;
  }
}


.face {
  position: absolute;
  width: 200px;
  height: 200px;
  border: solid green 3px;
  border-radius: 100vw
}


 

#front_face {
  transform: translateX(-100px) translateY(-100px) translateZ(100px);
  background: rgba(255, 0, 0, 0.5);
}

#back_face {
  transform: translateX(-100px) translateY(-100px) translateZ(-100px);
  background: rgba(255, 0, 255, 0.5);
}

#right_face {
  transform: translateY(-100px) rotateY(90deg);
  background: rgba(255, 255, 0, 0.5);
}

#left_face {
  transform: translateY(-100px) translateX(-200px) rotateY(90deg);
  background: rgba(0, 255, 0, 0.5);
}

#top_face {
  transform: translateX(-100px) translateY(-200px) rotateX(90deg);
  background: rgba(0, 255, 255, 0.5);
}

#bottom_face {
  transform: translateX(-100px) rotateX(90deg);
  background: rgba(255, 255, 255, 0.5);
}

.cube {
  transform: rotateX(90deg) rotateY(90deg);
}


<div id="cube-wrapper">
  <div class="cube">
    <div id="front_face" class="face"></div>
    <div id="right_face" class="face"></div>
    <div id="back_face" class="face"></div>
    <div id="left_face" class="face"></div>
    <div id="top_face" class="face"></div>
    <div id="bottom_face" class="face"></div>
  </div>
</div>

So, I reconsidered my approach and looked for a different method.

I looked at:

Then I tried again...the best I got were overly complicated 3d object illusions.

Like this:

body {
  overflow: hidden;
  background: #333;
}

.wrapper {
  margin: 1em;
  animation-duration: 20s;
}

.planet,
.planet:before,
.planet:after {
  height: 300px;
  width: 300px;
  border-radius: 100vw;
  will-change: transform;
  margin: 0 auto;
}

.planet {
  box-shadow: inset 0px 0px 10px 10px rgba(0, 0, 0, 0.4);
  position: relative;
}

.wrapper,
.planet,
.planet:before {
  animation-name: myrotate;
  animation-duration: 20s;
}

.wrapper,
.planet,
.planet:before,
.planet:after {
  animation-timing-function: linear;
  animation-iteration-count: infinite;
}

.planet:before,
.planet:after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
}

.planet:before {
  box-shadow: inset 20px 20px 100px 00px rgba(0, 0, 0, .5), 0px 0px 5px 3px rgba(0, 0, 0, .1);
}

.planet:after {
  filter: saturate(2.5);
  background: linear-gradient(rgba(0, 0, 0, 1), transparent), url("https://i.stack.imgur.com/eDYPN.jpg");
  opacity: 0.3;
  box-shadow: inset -20px -20px 14px 2px rgba(0, 0, 0, .2);
  animation-name: myopacity;
  animation-duration: 5000000s;
}

@keyframes myrotate {
  0% {
    transform: rotatez(0deg);
  }
  100% {
    transform: rotatez(360deg);
  }
}

@keyframes myopacity {
  0% {
    background-position: 0px;
    transform: rotatez(0deg);
  }
  50% {
    background-position: 100000000px;
  }
  100% {
    background-position: 0;
    transform: rotatez(-360deg);
  }
}


<div class="wrapper">
  <div class="planet"></div>
</div>

And this:

body {
  background: #131418;
}

.wrapper {
  margin: 1em;
  max-width: 100%;
  position: fixed;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}

.planet,
.planet:before,
.planet:after {
  height: 500px;
  width: 500px;
  max-height: 30vw;
  max-width: 30vw;
  border-radius: 100vw;
  will-change: transform;
}

.planet {
  box-shadow: inset 0px 0px 100px 10px rgba(0, 0, 0, .5);
  position: relative;
  float: left;
  margin: 0 2em;
}

.planet,
.planet:before,
.planet:after {
  animation-name: myrotate;
  animation-duration: 10s;
}

.wrapper,
.planet,
.planet:before,
.planet:after {
  animation-timing-function: linear;
  animation-iteration-count: infinite;
}

.planet:before,
.planet:after {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
}

.planet:before {
  box-shadow: inset 50px 100px 50px 0 rgba(0, 0, 0, .5), 0 0 50px 3px rgba(0, 0, 0, .25);
  background-image: -webkit-radial-gradient( top, circle cover, #ffffff 0%, #000000 80%);
  opacity: .5;
}

.planet:after {
  opacity: .3;
  background-image: -webkit-radial-gradient( bottom, circle, #ffffff 0%, #000000 -200%);
  box-shadow: inset 0px 0px 100px 50px rgba(0, 0, 0, .5);
}

@keyframes myrotate {
  0% {
    transform: rotatez(0deg);
  }
  100% {
    transform: rotatez(-360deg);
  }
}

.bg {
  background: wheat;
}


<div class="wrapper">
  <div class="planet bg"></div>
</div>

Which are okay until you try to actually rotate them on either the x-axis or the y-axis like the cube in my first example...here's what happens then: (simplified example)

.sphere {
  background: black;
  width: 300px;
  height: 300px;
  border-radius: 100vw;
  animation: myrotate 10s linear infinite
}

@keyframes myrotate {
  0% {
    transform: rotate3d(0, 0, 0, 0);
  }
  100% {
    transform: rotate3d(0, 1, 0, 360deg);
  }
}


<div class="sphere"></div>

All you get is a flat 2d object - which is expeceted considering that it's what the element is

The closest thing I found is the following shape created in a tutorial by Timo Korinth

@-webkit-keyframes animateWorld {
  0% {
    -webkit-transform: rotateY(0deg) rotateX(0deg) rotateZ(0deg);
  }
  50% {
    -webkit-transform: rotateY(360deg) rotateX(180deg) rotateZ(180deg);
  }
  100% {
    -webkit-transform: rotateY(720deg) rotateX(360deg) rotateZ(360deg);
  }
}

html {
  background: #FFFFFF;
}

. world {
  -webkit-perspective: 1000px;
}

.cube {
  margin-left: auto;
  margin-right: auto;
  position: relative;
  width: 200px;
  height: 200px;
  -webkit-transform-style: preserve-3d;
  -webkit-animation-name: animateWorld;
  -webkit-animation-duration: 10s;
  -webkit-animation-iteration-count: infinite;
  -webkit-animation-timing-function: linear;
}

.circle {
  position: absolute;
  width: 100%;
  height: 100%;
  border: 2px dashed #009BC2;
  border-radius: 50%;
  opacity: 0.8;
  background: rgba(255, 255, 255, 0);
}

.zero {
  -webkit-transform: rotateX(90deg);
}

.two {
  -webkit-transform: rotateY(45deg);
}

.three {
  -webkit-transform: rotateY(90deg);
}

.four {
  -webkit-transform: rotateY(135deg);
}

.five {
  width: 173px;
  height: 173px;
  margin: 14px;
  -webkit-transform: rotateX(90deg) translateZ(50px);
}

.six {
  width: 173px;
  height: 173px;
  margin: 14px;
  -webkit-transform: rotateX(90deg) translateZ(-50px);
}

So here's my

Question:

How do I create an actual 3 dimensional sphere with pure CSS? More specifically, one that is covered - not just a frame - and doesn't involve hundreds of html elements.

Notes:

  1. Three dimensional spheres have height, width and depth - just like the cube in my first example snippet
  2. I don't need any physics and there's no need for any user-interaction. Just an animated spinning sphere.

Solution 1 - Css

Strictly speaking, any "3D" shape on a flat screen is more an illusion of a 3D object. All we see is a 2D projection of that shape on the screen plane, and our brain does its best to guess which shape could give the projection we see. If the projection changes, our brain interprets it as a 3D object changing its orientation, which helps it to determine the shape of this object better.

It works well with non-symmetric objects and objects made from polygons (e.g., cubes), but the sphere is a very special case: its projection on the plane always gives just a circle. The static sphere and the rotating one have the same projection, the same circle. Even in real life, if we look at a sphere with a uniform surface without any marks on it (e.g., a polished metal ball), it is hard to determine if it stands still or rotates. Our eyes need some hints, some details that are moving along the surface of the sphere according to its geometry. The more such details move the way you expect from points on the spherical surface to move, the clearer is the perception (well, illusion) of the rotating sphere.

And here is the key to the problem in making a CSS scene that would give such perception: to make this illusion strong enough, we need many marks moving along the paths that lie in different planes. And the only way to get this in CSS is to have each mark as a separate CSS box (element or pseudo-element). If our sphere consists only of moving marks, we really need many of them to see it as a sphere — thus "hundreds of elements" in most demos you have seen.

So if you want to make a sphere look realistic with a reasonably small number of elements, you would probably need to combine the effects that make an "illusion" of a static basic spherical shape (a circle with radial gradients, inner shadows etc.) with some elements that are relatively small (to make it less obvious that they are actually flat), oriented along the surface of the sphere with 3D transforms, and animated — basically the same way as the faces of the cube in your first demo.

Below is my own attempt to put this approach into practice. I used 20 circular elements oriented roughly as the faces of the regular icosahedron (like white hexagons on the classic soccer ball). I grouped them into two groups each making one hemisphere for convenience (it was not necessary, but it made styling a bit simpler). The whole 3D scene consists of the sphere itself and the background frame (pseudo element) which crosses the sphere near its centre (a bit closer, to reduce "flickering" of the circles as they go from the near side to the far side and back) and always faces to the screen. So 24 elements in total (not literally "hundreds", at least:). To make the circles look more "bulging" (like spherical segments), I added two pseudo elements to each of them and elevated them slightly one above other. Works best in Chrome and Firefox 57+ (in Firefox 56- and iOS Safari there is still some "flickering" near the edges). If you hover the circle, you can see the scene without the background frame (and also without "flickering"). A slightly modified version is also available on Codepen.

Solution 2 - Css

How do I create an actual 3 dimensional sphere with pure CSS?

Well, as many have stated in answers and comments it is simply impossible to create a single 3D entity in a browser with html and css only at this point in time, but it is possible to create an illusion of a 3D Object. Below is my approach to solving the problem.

>To give a human eye the ability to see a spherical object, points of reference are needed for the eye to follow. In my case it is lines that define the shape of the sphere. The lines are achieved by giving a border to 5 elements that are in the X-axis set and 5 elements that are in the Y-axis set. Only X/Y sets are given a border, because that alone provides enough reference to make the illusion of a sphere. Additional lines on the Z axis are simply clutter and are unnecessary. If all lines are turned off, the entire thing appears like a solid "perfect" sphere (Looks like a circle, but all parts of it are moving and are present on the 3D plane in the browser!).

What I have done:

  1. Created 15 html elements that each will represent a circle split in 3 sets of 5 >The reason for all of these sets, is that when the entire contraption is rotated on x, y, z axis the backgrounds of each of the elements in x, y, z sets are filling the empty spaces for each other.
  2. Each set of 5 elements is rotated on X,Y,Z axis respectively in 36 degree increments. enter image description here
  3. All elements are rounded using border-radius:50%; 3 sets of 5 rounded elements for X Y Z axis
  4. Set background of the circle elements to a solid color Filled sets if 5 rounded elements
  5. Put the sets together, so they overlap
    enter image description here
  6. Clipped minor gaps that came as a result of not enough elements covering the empty spaces between x,y,z circles using clip-path: circle(96px at center); on the container, and threw a cool shade/light effect on to seal the deal
    enter image description here vs enter image description here >More circles will result in a less "edgy" sphere, but since the performance is stressed in the question, a quick clip of the entire thing seemed like the thing to do

As a closing thought, I wanted to express my appreciation of the question being asked, it really made me think and was a great project that lead to me learning a lot of things about 3D capabilities of html/css.

Also thanks to all the people who have spent the time to pry this open, and came up with awesome approaches to the problem.

I hope the fruits of my research are of use. Cheers!

Solution 3 - Css

As already mentioned above, CSS3 can't provide you with a real 3d shapes but just with the illusion. A good sphere illusion that use minimum HTML elements and use image as a texture can be done by a combination of what you have done and masking all with CSS shadows.

A nice touch that can make the mask more realistic is the use of the :after pseudo element for creation of an additional spark in shifted location and smaller size. A key thing for a successful effect is to remember that different materials reflect light differently. meaning if you're trying to create a metallic sphere the lighting created by the box-shadow will be different from the lighting of a plastic sphere.

Another nice addition is the use of the :before pseudo element for creation of reflection effect. Adding a premade image of the world on a sphere with some opacity can create a very persuasive effect. notice also with the reflection the material you are trying to create will determine the amount of opacity you want for the reflection.

Notice, I used octagonal prism for having the image behind the scene to look more round when the 3d trasform apply its perspective. Even with using only 8 elements the result is quite realistic. More realistic result can be done with more polygons and more complex shapes and texture mappings but even then no need for too many elements due to the addition of the shadow and the spark above everything.

Last, in order to hide the rest of the octagonal prism and display only the parts inside the sphere bounds I'm using clip-path: circle(99px at center);.

Solution 4 - Css

Making a realistic 3d css sphere, without some level of 2d illusion, would require many elements for it to have a smooth perimeter.

However, I made a version of Timo Korinth's example with:

  • Clipping of the "back facing" grid lines
  • Approximate spherical shading by moving a radial gradient

Can be rotated arbitrarily as long as the shading animation is recalculated.

This page has some of the maths behind implementing spherical shading with CSS that could be used for this.

Edit: Other answers look nicer, so converted it to a Death Star

Solution 6 - Css

No, it's not possible under your criteria. All examples of 3D stuff using only HTML and CSS have performance issues, because that's not its purpose.

When it comes to heavy graphical effects, HTML and CSS are really bad at it.

The best way to make a real 3D sphere is using WebGL, which is an JavaScript API for creating 3D content.

Solution 7 - Css

Have a look at this - sound like what you need and with code snippes you could hopefully edit to your liking. https://codepen.io/Mamboleoo/post/sphere-css

HTML

.mommy
.daddy
  - for (var x = 1; x < 300; x++)
    span

Solution 8 - Css

Only way I can see without JavaScript+WebGL is to use custom filters to write a vertex shader that maps the vertices of the 6 cube faces to a sphere. You take the vertex normals and multiply them by the sphere radius. There will be some stretching, but it's as good as it gets in CSS
