Z80Lib3D::Primitives::Rotation¶ ↑

The elements of this object can be used to construct rotation matrices Rα, Rβ, Rγ.

Each Rotation member is a 16-bit fixed point, twos complement signed number with the integral part in its high 8 bits and the fractional part in its low 8 bits, in the range: [-1.0, 1.0].

Rotation members:

• sin_a: word

• cos_a: word

• yaw: SinCos alias of (sin_a, cos_a)

• sin_b: word

• cos_b: word

• pitch: SinCos alias of (sin_b, cos_b)

• sin_c: word

• cos_c: word

• roll: SinCos alias of (sin_c, cos_c)
