Displacement Shaders

The basic displacement function is:

public void displacement(output point P; output normal N)
{
      //initialize m_shadingCtx variable just in case it had been used before
      m_shadingCtx->init();

      //assign m_hump variable based on wavelet noise
      exampleVariable = something_To_Make_It_Change_Like_A_Map

      //displace based on m_hump
      m_shadingCtx->displace(vector(normalize(N)),exampleVariable, "displace");

      //reinitialize m_shadingCtx
      m_shadingCtx->init();
}

Which creates the sphere on the right. If the last "m_shadingCtx->init();" is omitted, the shader turns into a toon shader like the one on the left! Hooray for experimentation!
