If "Fixed width" is checked, the canvas width is stretched to the value of the "Width" field. If not, each swap will use "Swap width" pixels. For more details check this blog post.

This is a test of the MojoMagnify Javascript Image Magnifier script posted here. Move the mouse over the images to see it in action. The first image uses a larger version to get a magnification effect, the second image uses a b/w and a color version of the same image (the same size) to get another effect. The image is also automatically made to link to the high res version (if the image is not a
Render lights Lighting Backface culling Z-sorting Filled faces Wireframe Texture Texture shading Select a model from the list. Click and drag mouse to rotate. Use +/- to zoom in and out. This application loads arbitrary 3D models and renders them using "2d" context on the <canvas> element. It was made to test the possibility of displaying (very) simple 3D models using just javas
This is another small demo, testing the capabilities of the Javascript/Canvas 3D renderer. This time we're doing a bit of special effects in Javascript. The excanvas support for Internet Explorer is currently broken in the 3D renderer, so only Firefox, Safari and Opera users get to experience cool Javascript smoke and fire in the browser for now. Click and drag mouse to rotate, use "w"/"s" to zoom
This is a test of the GPS part of the Javascript EXIF library previously posted here. Below you should see a small gallery and an empty Google map. Click one of the images to show a larger version. GPS coordinates embedded in the image are read via JavaScript before they are fed to the Google map, which should center on the position where the image was taken. The binary file access happens in
Click the effect names in the table to apply effects to the sample image. Original image: Processed image: Effect Compatibility This library tries to enable different client side image effects. IE has long had its filters, which have provided a few basic effects for IE. With canvas, some of these effects can also be achieved in Firefox and Opera. Safari lacks the getImageData/putImageDa

This is a work-in-progress 3D Javascript chess game, rendered using the canvas element and this Javascript 3D renderer. Special chess moves are not implemented yet and the interface needs a bit of work. Click and drag the mouse to rotate the board. Either move pieces by clicking on them (valid target squares will be shown in green) or use numpad 2,4,6,8 to move the selector square and 5 to se
Below is a list of the experiments related to JavaScript game development here at Nihilogic.dk. Head over to the blog for the most recent updates and developments. Be warned that most of these games are highly experimental and should not be seen as complete games but rather as technical demos and proof-of-concept experiments. Due to the nature of these demos, some of them only work in certain brow

This is a test of the Javascript EXIF library posted here. Click the images to see it in action. The first image tests reading single tags, while the other two simply show all available data. The binary file access happens in binaryajax.js and the EXIF data reading happens in exif.js. Also check out the jQuery plugin, if you're into that sort of thing!
