コードは波の形と色を決める部分に大きく分けられる。

• 形
  • noise
  • octave(重ね合わせ)
  • choppy(鋭さ)
• 色
  • fresnel的な屈折光と反射光の合成(拡散光で良い)
  • 白いギラギラした照り返しを表現するspecular

• 深度とカメラ距離の加味（浅さと深さで明るさ調整）

I succeeded with this modification. I'm making static library and its test.

add this to Application.mk

APP_PLATFORM := android-9
APP_STL := gnustl_static
NDK_TOOLCHAIN_VERSION=clang

APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -std=c++11 -fsigned-char # you can reduce this options
