Implementing iBooks page curling using a conical deformation algorithm
One of iPad's most talked about apps is Apple's own iBooks e-reader. Perhaps its most eye-catching but completely superfluous feature is the beautiful, dynamic page curling effect that follows your finger naturally as you drag to turn pages. Unlike cheap implementations using simple masks and gradients, iBook's page curling is very realistic, with content that bleeds through and deforms accurately
Or to be technical, I made a thing that makes things like that thing. (If your device doesn’t render it, it looks like this.) Backstory: a month and a half ago I left my job to make an indie game. One of the many things on my to-do list was “Learn shader programming”, and around that time I ran across this blog post by Roger Alsing about using genetic algorithms to create images. So I tried the sa
Bumpy Metaballs | Click and drag to rotate, mouse wheel to zoom. Double-click to go fullscreen.Go fullscreen Isosurface created with Marching Cubes, and bump added with normal mapping. The metaballs don't have generated UV coordinates, and tangents can't be calculated with the usual method because it relies on texture coordinates. Following the triplanar mapping explained in this GPU Gems 3 articl

Drag n Drop panels are great to let the user control how he/she wants to see the information as he can arrange various information blocks according to his preference. This type of functionality is often provided by web portals or personal homepage services like iGoogle. Similarly, WordPress dashboard also lets user control how the various boxes are displayed. Today, i am going to show you how to c

ドラッグ＆ドロップAPIを理解する近道は、ドラッグ＆ドロップという処理は「ドラッグ元」と「ドロップ対象の要素」という2種類の要素が関連していることをきちんと意識することである。 ドラッグ元はWebページ内の要素であったり、他のアプリケーションかもしれない。「ドロップ対象の要素」は、デフォルトではドラッグ＆ドロップを受け付けないということを覚えておくとが重要である。 ドラッグ元の指定（draggable属性） Webページ内の要素をドラッグ元とする場合は、その要素にdraggable属性を指定する。draggable属性がとりうる値は3つある。"true"、"false"、そして価なし、という状態である。"true"と"false"はそれぞれドラッグ可能／不可能を明示的に指定している。値を指定しない（例： ）場合は、「デフォルト」の動作をそのまま使用するという意味になる。デフォルトの動作とは
