Detailed Description

Four-component float vector for homogeneous coordinates, RGBA values, and shader constant payloads.

Wraps Vector<float, 4> with the same accessor pattern as Vector2D and Vector3D, adding a W component. Reach for it when a value has to survive a Matrix4 transform with its translation intact (w = 1 for points, w = 0 for directions), or when you are packing four floats for the GPU.

using Sleak::Math::Vector4D;
 
Vector4D point(1.0f, 2.0f, 3.0f, 1.0f);      // a position
Vector4D direction(0.0f, 1.0f, 0.0f, 0.0f);  // a direction
Vector4D tint(1.0f, 0.95f, 0.85f, 1.0f);     // RGBA
 
float alpha = tint.GetW();
