Expand description

System globals shared across all nodes

Bound to @group(0) @binding(0) in all shaders. This provides common values that are the same for all nodes in a render pass.

Layout follows std140 rules:

vec2 = 8 bytes, 8-byte aligned
vec4 = 16 bytes, 16-byte aligned
Total size must be multiple of 16 bytes

Fields§

§time: f32

Time since engine start in seconds

§delta_time: f32

Delta time since last frame in seconds

§frame_count: u32

Current frame count

§resolution: [f32; 2]

Screen resolution in pixels (width, height)

§mouse: [f32; 2]

Mouse position normalized to 0.0-1.0 (x, y)

§audio_volume: f32

Audio analysis: overall volume (0.0-1.0)

§audio_bass: f32

Audio analysis: bass frequencies (0.0-1.0)

§audio_mid: f32

Audio analysis: mid frequencies (0.0-1.0)

§audio_high: f32

Audio analysis: high frequencies (0.0-1.0)

§beat_bpm: f32

Current BPM (beats per minute)

§beat_phase: f32

Beat phase (0.0-1.0, 0.0 = on beat)

§beat_count: u32

Cumulative beat count

§external_input_1: f32

External input 1 (OSC, sensor, SNS, etc.)

§external_input_2: f32

External input 2 (OSC, sensor, SNS, etc.)
