The world's 1st interactive sunlight & shadow app. Visualize light for any location, time, and date. Perfect for solar energy, real estate, architecture, photography & more!

SunCalc shows the movement of the sun and sunlight-phase for a certain day at a certain place. You can change the suns positions for sunrise, selected time and sunset see. The thin yellow-colored curve shows the trajectory of the sun, the yellow deposit shows the variation of the path of the sun throughout the year.

下一篇文章我们就开始讲讲point light和spot light怎样使用shadow map来产生阴影。 效果如下： 最后强烈推荐大家看一下LearnOpenGL对于shadow map的解释：

2015年2月12日 · This app connects an interactive Google World Map to a 3D Sun-path diagram, shadow map generator and a 2D SVG chart displaying a range of solar information. The SVG chart defaults to showing the annual variation in day-length, but you can also select an analemma chart or several different types of 2D Sun-path diagram.

ShadowMap是实时渲染中阴影的一种实现方式，其原理是： 我们在 光源视角 下渲染一张 场景深度图，这张深度图保存了在光源视角下 最前面的物体的深度，然后我们在渲染自己场景时，将在 相机视角 下的点转化到 光源视角 下（LookFromLight），再通过裁剪矩阵（Project）投影到视图上，此时我们可以知道场景中某一点在光源视角下应当对应那个位置的像素，通过比较之前得到的 深度图 对应位置像素的值，我们可以知道，当前视角下的这个点在光源位置来看，是否被遮 …
