# TerrainWithHole
This repository was made to learn how to make hole in terrain.
I tried two methods. The first is to partly remove geometry data from terrain by using memoryview.
The second is to draw a shape on a hightmap by OpenCV, make the shape transparent, and use 'discard' in a shader, which was inspired by the panda3D community site "https://discourse.panda3d.org/".
The first way does not need to use 'discard' in shaders.
And made it possible for the character to go through the hole by embedding a plane model under ground near the hole, and ignoring the collision between the character and terrain if the embedded plane model is detected by ray cast.
