Obesity represents one of the most important health risks for a steadily increasing part of the population. The effort to prevent it or fight it is often hindered by the fact that a considerable percentage of individuals perceive their body image as healthier than it actually is. It is, therefore, essential to enhance awareness on actual body figure and weight state. In the current work we attempt to achieve this goal through visual feedback on the actual individual's image, increasing the impact by animating the transition from the initial state to the future outcome. The proposed module commences from a current body figure image and, relying on lifestyle and dietary information, gradually warps it to reflect expected changes. The mechanism relies on pure WebGL/Javascript, animating the transition at a selectable pace and to the extent chosen by the user, based on triangulation of the body figure outline and warping of the resulting polygon and corresponding texture according to input parameters. The WebGL/Javascript platform in combination with the absence of usage of external libraries allows for a small footprint of the module while offering high portability due to its native support by most modern day browsers.

肥胖对于不断增加的一部分人口来说是最重要的健康风险之一。事实是，很多人认为自己的身体比实际状况更健康，因此阻止或预防这种疾病的努力常常受到阻碍。因此，必须提高对实际身材和体重状态的认识。在当前的工作中，我们尝试通过对实际个人图像的视觉反馈来实现此目标，并通过动画化从初始状态到未来结果的过渡来增加影响。拟议的模块从当前的人体形象开始，并根据生活方式和饮食信息逐渐变形以反映预期的变化。该机制依赖于纯WebGL / Javascript，根据人体轮廓的三角剖分以及根据输入参数生成的多边形和相应纹理的变形，以可选的速度和用户选择的程度对过渡进行动画处理。WebGL / Javascript平台与不使用外部库的结合，使模块占用空间小，同时由于大多数现代浏览器的本机支持而提供了高可移植性。
