Detailed Description

[AI] 4D point class for floating point values.

[AI] This class extends the Vector4 class, adding storage for 4D point coordinates using float precision. It provides various constructors and utility methods to manipulate 4D points, such as setting/getting each coordinate, assignment, and array-style access. This is especially useful in graphics or spatial transformations where a homogeneous coordinate is needed.
