Struct hkVector4

#[repr(C)]
pub struct hkVector4 {
    pub quad: hkQuadReal,
}

Represents a 4D vector using SSE-aligned floating-point values in the Havok system.

This struct wraps a hkQuadReal (__m128) for vector operations.

Memory Layout:

• quad: SSE-aligned 128-bit vector (0x00 - 0x0F)

Fields

quad: hkQuadReal

The 128-bit SSE vector containing x, y, z, and w components.

• Offset: 0x00
