Attract Geometric¶

The geometric mode renders clusters of semi-transparent rotating rectangles with sinusoidal fade cycles, distance-based glow effects, and drifting pseudocode text fragments. The effect is a 1:1 port of the website's geometric background animation into the CyberHUD display system, preserving all mathematical formulas, constants, and visual behavior from the original TypeScript source.

Options¶

Key	Type	Description	Default	Allowed Values
`speed`	float	Animation speed multiplier controlling how quickly geometric clusters rotate and shift position	1.0	any valid float (0.1–10.0 recommended)
`density`	float	Cluster count scaling factor from sparse (0.1) to maximum cluster coverage (1.0)	0.5	any valid float (0.1–1.0)
`glow_intensity`	float	Glow effect strength from subtle (0.0) to full luminous bloom on cluster elements (1.0)	1.0	any valid float (0.0–1.0)
`fragment_rate`	float	Pseudocode fragment spawn rate controlling how frequently text fragments drift across the display	1.0	any valid float (0.0–2.0)

Policy Fields¶

Field	Type	Range	Default	Description
speed	float64	[0.1, 10.0]	1.0	Animation speed multiplier
density	float64	[0.1, 1.0]	0.5	Cluster count scaling
glow_intensity	float64	[0.0, 1.0]	1.0	Glow effect strength
fragment_rate	float64	[0.0, 2.0]	1.0	Pseudocode fragment spawn rate

CLI Examples¶

Query the current policy values:

cyberhudctl display attract_geometric

Set a faster animation speed with higher cluster density:

cyberhudctl display set 0 attract_geometric speed=2.5 density=0.8

Configure glow and fragment rate on an active region:

cyberhudctl display config main.0 glow_intensity=0.6 fragment_rate=1.5

Panel Compatibility¶

Color TFT — full-color rendering with semi-transparent rectangles, distance-based glow layers, and smooth sinusoidal opacity fades.
Monochrome OLED — rectangles and glow rendered in grayscale intensity; pseudocode fragments remain legible against the animated background.
Slow Refresh — a single static frame is produced at time=0 with all clusters at full fade-in and no fragment text, avoiding refresh artifacts.

Slow Refresh Behavior¶

On slow-refresh panels, the geometric mode produces a single static frame suitable for displays that cannot handle continuous animation. All clusters are rendered at full fade-in with no pseudocode fragments, and the RenderCacheKey remains stable after the initial frame to prevent unnecessary refreshes.
