perform a component-wise greater-than-or-equal comparison of two vectors
bvec2 greaterThanEqual(ivec2 x, ivec2 y)bvec3 greaterThanEqual(ivec3 x, ivec3 y)bvec4 greaterThanEqual(ivec4 x, ivec4 y)bvec2 greaterThanEqual(vec2 x, vec2 y)bvec3 greaterThanEqual(vec3 x, vec3 y)bvec4 greaterThanEqual(vec4 x, vec4 y)x: Specifies the first vector to be used in the comparison operation.y: Specifies the second vector to be used in the comparison operation.greaterThanEqual returns a boolean vector in which each element i is computed as x[i] ≥ y[i].
