Function Documentation

ALIGN()

union ALIGN

(

16

)

3D vector compute type (16 bytes, 16-byte aligned).

4D vector compute type (16 bytes, 16-byte aligned).

Memory Layout:

• [0]: x component (used)
• [1]: y component (used)
• [2]: z component (used)
• [3]: w component (padding, zero-initialized)

The W component acts as padding to maintain 128-bit alignment and is kept at zero for safety when accidentally using 4D operations.

Memory Layout:

• [0]: x component (used)
• [1]: y component (used)
• [2]: z component (used)
• [3]: w component (used)

All components are active. Commonly used for:

• RGBA colors
• Quaternions
• Homogeneous coordinates (x, y, z, w=1.0)
• 4D transformations
