Webgl hover effects

The reveal hover effect on images has become a very popular pattern in modern websites. It plays an important role in taking the user experience to a higher level. Natural movements with a realistic feel are much more enjoyable for the user.

The aim is to add fluid and interesting motion to the effects. We will be exploring three different types of animations. This dynamic experience consists of two parts:.

We assume that you are confident with JavaScript and have some basic understanding of Three. The markup for this effect will include a link element that contains an image and some other elements that are not of importance for our effect :. As a result, each effect will extend EffectShell. First of all, we need to create the Three. In our markup we have links with images inside. The next step is to get each link from the DOM and put them in an array.

Because we will use the images as a texture, we have to load the textures through Three. Otherwise our texture will be fully black.

At this point we get an array of items. Each item contains an ElementImageIndex and Texture. Then, when all textures are loaded we can initialize the effect. Once we have created the scene and loaded the textures, we can create the main effect. But we need to scale the plane in order to fit the image dimensions otherwise the texture will be stretched. Here comes the first mathematical part of this tutorial.

So, we need to remap the mouse coordinate to the view size of our scene. First, we need to get the view size of our scene.

This solution is provided by ayamflow. We are going to remap the normalized mouse position with the scene view dimensions using a value mapping function. Once correctly animated, we have to put uAlpha as alpha channel inside fragment shader of the plane material.

Then we multiply it by the uOffset value that we calculated beforehand and we get the curve distortion thanks to the velocity. To make a trail-like effect, we have to use several planes with the same texture but with a different position animation duration. The main purpose of this tutorial was to show how to create motion-distortion effects on images, but you can play around with the base effect and add something else or try something different.

The playground reacts on mouse movements. Just cross it to see the effect in action. It also has the ability to return to its original state. The canvas features dozens of particles that smoothly but chaotically move in various directions. Use your mouse to create links between two neighboring points. The solution is pretty popular nowadays: it can be seen in numerous creative websites and even in regular corporate ones. This idea can come in handy when you need to spice up galleries or grid-based displays of portfolio pieces.

Since this is just an experiment, it works only in the latest versions of Chrome, Opera and Safari. Renato Ribeiro has equipped a mouse cursor with a vibrant relatively long bubble-style fading trail.

They will make your website come to life and burst with freshness. There are many animation libraries to choose from. Before we take a look at some cool ones, it may be a good idea to spend some words on JavaScript effects and animations generally.

What are they? Design and functionality have both evolved steadily with that evolution, and are now more advanced than anyone could have predicted. The very first text-only websites were instruction-like tutorials.

Not much more than an extensive Ikea manual. Now we have an entire society of active participators in the creation of wonderfully new and unique forms of online media. The early result: vertically-structured text pages with few graphics. We got blue underlined hypertext to make navigating easier — great!

But we needed more, and along came CSS. Cascading Style Sheets, or CSS, made styling and formatting easy to implement across multiple pages of a single website. Web design templates helped people create and publish their own websites. We need the power of JavaScript! CSS is still very much alive. But JavaScript is more advanced.Interactivity and play were big. Sound, shape and movement marked the most interesting web presences around and we are excited to see what's coming next.

It doesn't matter if you are a beginner or intermediate, start learning CSS now. I started to dig into WebGL a couple of months ago and love such effects. In this demo, I think it would have been better to order the examples in a pagination, the site is very laggy. And maybe it could be optimized with reducing the console output? Work very poorly on Chrome about 0. It plays well locally on Edge, and intermittently on Firefox. Good morning, thanks for all your work, means a lot to me, and help me always!!

Thanks for all your fantastic work…. Great work, very inspiring! It really is nice work though. This is such a fun transition! Thank you for sharing. I am experimenting with the code and it is only allowing effects on the page? Is that something in the three. Do you know how to change to an indefinite amount of usage?If you remember the launch of Windows 95, then you might remember the Hover. If you had any free time on your hands back then, you may have even been good at it like this guy!

And you can download our WebGL boilerplate project and create your own 3D shader. Game on! Hover was among the first 3D games that ran on Windows. Even though its multimedia capabilities were sophisticated for the time, by modern standards it is a pretty simple game.

This makes it a perfect example to help you learn the basics of WebGL and even discover some practical application to your project. Thinking in 3D can also be a lot different than writing a 2D game. While WebGL is a general purposes graphics library, its best known for its 3D capabilities and, prior to its introduction, there was no way to render real 3D scenes in a browser without using a plug-in.

Beyond games, 3D can be used in a variety of ways to enhance learning and understanding in web pages and apps. This enables all kinds of exciting experiences on the web without the need for plugins, including games like Hover! More importantly, WebGL is becoming mainstream and with its introduction in Internet Explorer 11it has some level of support in all major browsers.

In the original Hover game, most of the 3D came in the form of walls and floors—flat objects with perspective applied to them.

Those 2D graphics were scaled and positioned to match the 3D game, but there was no real 3D processing applied to them. Models are definitions of the physical objects in the scene.

In Hover, for example, we created models for each of the crafts and all of the pickups. Where the fundamental unit of a regular 2D graphic is a pixel, the fundamental unit of a 3D model is a polygon, typically a triangle in 3D space. When you place enough of those polygons next to one another, a three-dimensional object emerges much like many pixels combine to create a 2D image. They paint life onto the model to make it seem more realistic. Here is an example of a texture that we use when rendering one of the crafts in the game:.

Finally, after you place the models into the scene and apply their corresponding textures, you finalize the 3D effect by placing lights into the scene. Some lighting is pretty basic. An ambient light, for example, will light the entire scene in a roughly even way.

You can also create spotlights, directional lights and point lights, all of which can light objects within the scene in different ways. This is a mathematically intense operation, but one that modern GPUs are very good at! In fact, the high framerate animation in a game like Hover means that the scene is being rendered and rerendered up to 60 times per second.

Because that code needs to be very fast, some of it gets executed directly on the GPU. That code is called a shader. All the objects added into the 3D scene are eventually processed by two special shaders: the vertex shader and the fragment shader. The vertex shader operates on each vertex within the scene and transforms the vertex from 3D space in to 2D space for rendering to the screen. Remember that a vertex defines the boundary between two triangles in a model. Custom vertex shaders can transform the way that boundaray looks on the, maybe deforming it to smooth out a surface or create realistic effects like water ripples or waves.
