Bit Resolution - Rotation
For storing a 2D rotation as a bit sequence, the bit depth determines the angular resolution of the rotation.
The forumula 360 / 2 ^ bitDepth gives the angular resolution in degrees;
The finest turn possible for a given bit depth.
| Bit Depth | Resolution | Steps | |
|---|---|---|---|
| ↓ | 1 bit | 180° | 2 |
| ↓ | 2 bits | 90° | 4 |
| ↓ | 3 bits | 45° | 8 |
| ↓ | 4 bits | 22.5° | 16 |
| ↓ | 5 bits | 11.25° | 32 |
| ↓ | 6 bits | 5.625° | 64 |
| ↓ | 7 bits | 2.8125° | 128 |
| ↓ | 8 bits | 1.40625° | 256 |
| ↓ | 10 bits | 0.3515625° | 512 |
| ↓ | 12 bits | 0.0878906…° | 4096 |
| ↓ | 14 bits | 0.0219727…° | 16384 |
Notes
The above example works best on touchscreens just for zooming in and looking closer.
