//============================================================================
// cone_uniform_vector
//============================================================================
// Returns uniformly distributed unit vector on a [0, 0, 1] oriented cone of
// given apex angle and uniform random vector xi ([x, y] in range [0, 1]).
// e.g. cos_half_apex_angle = 0 returns samples on a hemisphere (cos(pi/2)=0),
// while cos_half_apex_angle = -1 returns samples on a sphere (cos(pi)=-1)

// When creating shaders for Universal Render Pipeline you can you the ShaderGraph which is super AWESOME!
// However, if you want to author shaders in shading language you can use this teamplate as a base.
// Please note, this shader does not necessarily match perfomance of the built-in URP Lit shader.
// This shader works with URP 7.1.x and above
