External 3D Models:
is a fast Script Library to animate HTML+CSS pages in 2D and 3D using HTML 5 canvas, tries to use WebGL™ and hardware graphic acceleration with 2D canvas fall-back. It integrates well with HTML and CSS to animate many CSS formatted HTML elements (like <img> and <p>).

Under good conditions the library directly uses hardware graphic acceleration and its performance critical parts run directly on the computers graphic unit. This provides an extreme performance gain compared to DOM and script based animations and allows you to run smooth animations with thousands of elements.

If no hardware acceleration is present (or if it is not usable because of the browser or the graphics driver) the library uses the HTML 5 - 2D canvas which provides quite fast animations with restricted features on fast computers as well.

For slow graphic accelerators and/or slow processors that can not handle the full screen resolution smoothly, the library plays the animations only on a portion of the screen or becomes completely inactive to not interfere normal operations on the page.

On older browsers that do not support HTML 5 canvas and no animations show up.

The library is written in JavaScript and GLSL (a C like vector programming language). If supported, the GLSL parts are downloaded into the graphics card and executed there; possibly in parallel on several processors, which gives a dramatic performance gain.
taccgl™ is an HTML 5 library making special use of the new canvas feature. HTML 5 means that the library explicitly runs only on newer browsers, e.g. IE 9.0 and up, current versions of most other browsers. For older browsers it becomes inactive, the idea is that users can still view pages that include the library, however without the animations.

taccgl™ can display CSS formatted HTML elements with the new HTML5 3D canvas which makes the benefits of canvas 3D available for HTML elements as well:

For example HTML elements can be animated using GPU acceleration, they can be moved, accelerated, deformed, bent, lighted etc. and they can enjoy the performance of the GPU which normally has enough power to separately animate thousands of copies of (parts or fragments of) HTML elements.

Also HTML elements can be fully integrated into a 3D scene, e.g. they can rotate in 3D, they can be displayed before or behind other HTML elements even partially, and they can cast shadows or shadows can be casted on them. In addition HTML elements can be mapped on 3D objects such as cubes or spheres.

taccgl™ allows you to create WebGL™ animations with very few lines of javascript, by
  • animating CSS formatted HTML elements
  • mapping of HTML elements on 3D objects
  • displaying 3D objects created with a modelling program (e.g. Blender) and aligning them with HTML and CSS

The new HTML 5 canvas feature in its 3D version brings fantastic new graphic and animation features, such as

  • direct access to the clients GPU graphic acceleration unit,
  • performing of animations with thousands of triangles,
  • separately controlling every pixel and to calculate each pixel's color once per frame,
  • loading shader programs into and executing them in the GPU thereby bypassing javaScript and DOM performance bottelnecks,

and also special 3D features such as

  • 3D depth buffering for hidden surface handling,
  • 3D lighting for simulating light sources and reflection on 3D objects, and
  • automatic 3D shadow calculation.

In pure HTML 5 canvas 3D/WebGL™ the content to be displayed must be individually programmed. The taccgl™ library greatly simplifies this process. by allowing the user to use CSS formatted HTML elements togehter with 3D Models created with a modelling program.

Hover or click on the various green links on this page to see pop-ups containing additional explanations.

The appearing pop-up window is displayed using taccgl™ and WebGL™, mostly (performance of the GPU permitting) to correctly display its shadows. Note that the shadow can be quite complex, since the underlying page is not flat but seen as a 3D surface.

In addition opening and closing animations are played. The opening animation is choosen randomly from various opening animations that are e.g. morphing the element from a circle or a wavs from to its final rectangular form. The closing animation makes the element explode into many parts.

Hover or click on the various 3D objects and screenshots to see animations enlarging and rotating the objects.

taccgl™ Features

  • Library for 2D and 3D graphics and text, transitions and animations using WebGL™ for Webdesign of general purpose HTML pages.
  • Detect browsers/clients without appropiate WebGL™ and keep pages operational; assist in or automatically showing alternative content (e.g. canvas 2D)
  • Animates CSS formatted elements, Canvas 2D drawings, parts, slices, and deformed fragments thereof, and 3D objects from model files.
  • Provides transitions for linear and accelerated motion, rotation, color, fading, clipping, growing, shrinking, texture motion, deformation, morphing, etc as detailed below.
  • Consistent hidden surface handling, lighting, and shadows over all animated elements including HTML elements and 3D objects.
  • Perform many thousands of parallel transitions using GPU acceleration.
  • Per pixel calculation of lighting, colors, shadows, and user defined functions.
  • Easy content creation with HTML, CSS, and simple javaScript.
  • Fluent interface to apply transitions on multiple selected elements/objects.
  • Initial and permanent measurements and estimates of performance and frame rate and based on that Fall-Back and Graceful Degradation mechanisms for browsers/clients that do not support WebGL with the required performance including, disabeling shadows, dynamically reducing canvas size, using HTML5 canvas 2D instead of WebGL™, and finally completely disabeling animations (e.g. IE 8).
  • Depending on client/browser uses HTML 5 canvas 3D (WebGL™) or canvas 2D.
  • Even in canvas 2D mode simulates some 3D features, see below.
  • Animates 3D Models (OBJ and MTL files) in WebGL™ Mode.
  • Automatically generated and user defined shader programs.
  • Open source, BSD like license.

3D Features in Detail

In fact most of the animations shown in 2D so far work in 3D as well: Move back (z>0) and forward (z<0), Rotate around X, Y, and Z axis, Move and Rotate around X, Y, and Z axis, Rotate around XY, YZ, and XZ diagonal.

All HTML/CSS elements displayed normally appear in a z=0 plane. Elements displayed using taccgl™ use the same x and y coordinates (in pixel with origin in the top left corner of the current window or frame) and may have a positive z coordinate when moving behind and a negative z coordinate for moving in front.

Hidden Surface Elimination / Depth Buffering

Correclty displays Elements depth information, even if elements cut through each other, see also Introduction Cube

CSS Transition Visibility

Comparision of taccgl™ transitions and CSS transitions for the visibility property. more

CSS Transition Display

CSS transitions on the Height property can gradually display / un-display elements in a way that other elements fill up the resulting empty space, like display:none, which does not work gradually. These can easily be combined with taccgl™ transitions more

HTML5 Canvas Animation

Morphing and Deforming of CSS formatted HTML elements

taccgl™ includes functions for deformation and morphing of HTML elements. For example an element can be morphed from a rectangle into a circle or it can be mapped on an uneven waveformed surface more

When showing, viewing, or developing animations and/or computer games take care about epilepsy. A warning message shows up before viewing the examples.

Beta Version 0.59 Released

HTML5 Canvas 3D Animation

Version 0.59 was released on November 17, 2014, providing methods for parallax scrolling more

The development of mobile and responsive sites is explicitely supported and a beta of the mobile home page of taccgl™ demonstrates this. Read more about development of Responsive and Mobile Layouts. Also the taccgl™ tutorial and most of the documentation pages now have a responsive layout.

The library now also works locally on file:// urls (see Installing the Library) and can so be tested without the need of a web server (local or remote).

This is a beta release and quite naturally it contains bugs and is not yet completely implemented (e.g. does not yet implement all HTML tags and not all CSS properties). See Restrictions. We would be happy for bug reports and comments.

taccgl™ is provided under an open source BSD like License. You can download the library and place it on your test web server.
