Bending a mesh with a shader using a sine function in Unity

This is a simple shader for Unity to bend a mesh with a sine function. Useful when you want to simulate the bending caused due to some force(like weight) being applied to an object. The sine function is being plotted along the Z axis, if you want to bend along the X axis edit line 36 vertexPos.z to vertexPos.x like this:

float4 result = (float4(0.0 , ( sin( ( _OffsetSin + ( vertexPos.x * _Frequency ) ) ) * _Amplitude ) , 0.0 , 0.0));

The more vertices your mesh has along the axis you want to bend the smoother it will look.

If you don't want to download or clone the whole project here's the shader only.

Tested with Unity 2018.2
