Abstract
When the wind stops and the wave of the surface of the water disappear, the surface of the water acts like the mirror. Distant view of high mountain and high building and trees in riverside and lakefront are reflected the water. Actually Kinnkakuji and Taj Mahal were built that intended to reflect the water. The purpose of this paper is to analyze the reflection landscape through simple mathematical models. First, we show four features on the reflection landscape for a building by the concept of size of appearance. Second, we focus on the reflection landscape for a tree, and we calculated the amount in which green was seen based on solid angles.
