- Created analysis/visual_output_comparison.md with detailed architectural comparison
- Added capture utilities for output comparison (capture_output.py, capture_upstream.py, compare_outputs.py)
- Captured and compared output from upstream/main vs sideline branch
- Documented fundamental architectural differences in rendering approaches
- Updated Gitea issue #50 with findings
- demo_oscilloscope_pipeline.py: Switches between text mode and Pygame+PIL mode
- 15 FPS frame rate for smooth viewing
- Mode switches every 15 seconds automatically
- Pygame renderer with waveform visualization
- PIL converts Pygame output to ANSI for terminal display
- Uses fonts/Pixel_Sparta.otf for font rendering
Usage:
uv run python scripts/demo_oscilloscope_pipeline.py --lfo --modulate
Pipeline:
Text Mode (15s) → Pygame+PIL to ANSI (15s) → Repeat

- demo_oscilloscope_mod.py: 15 FPS for smooth human viewing
- Uses cursor positioning instead of full clear to reduce flicker
- ModulatedOscillator class for LFO modulation chain
- Shows both modulator and modulated waveforms
- Supports modulation depth and frequency control
Usage:
# Simple LFO (slow, smooth)
uv run python scripts/demo_oscilloscope_mod.py --lfo
# LFO modulation chain: modulator modulates main oscillator
uv run python scripts/demo_oscilloscope_mod.py --modulate --lfo --mod-depth 0.3
# Square wave modulation
uv run python scripts/demo_oscilloscope_mod.py --modulate --lfo --mod-waveform square
Related to #46
- Add --lfo flag for slow modulation (0.5Hz)
- Add --fast-lfo flag for rhythmic modulation (5Hz)
- Display frequency type (LFO/Audio) in output
- More intuitive LFO usage for modulation applications
Usage:
uv run python scripts/demo_oscilloscope.py --lfo --waveform sine
uv run python scripts/demo_oscilloscope.py --fast-lfo --waveform triangle
- demo_oscilloscope.py: Real-time oscilloscope display with continuous trace
- Shows waveform scrolling across the screen at correct time rate
- Supports all waveforms: sine, square, sawtooth, triangle, noise
- Frequency-based scrolling speed
- Single continuous trace instead of multiple copies
Related to #46
- Implements pipeline hot-rebuild with state preservation (issue #43)
- Adds auto-injection of MVP stages for missing capabilities
- Adds radial camera mode for polar coordinate scanning
- Adds afterimage and motionblur effects using framebuffer history
- Adds comprehensive acceptance tests for camera modes and pipeline rebuild
- Updates presets.toml with new effect configurations
