投影点

Applies a projection matrix to a point. Specifically, this node turns the given Euclidean vector (X, Y, Z) into the homogeneous vector (X, Y, Z, 1), multiplies the given projection matrix by it, and turns the resulting homogeneous vector back into a Euclidean one by dividing it by the absolute value of its W component. This last step is also known as perspective division.
