ofxBbbDmx

openFrameworks (v0.12.1+) integration layer for bbb-dmx / bbb-artnet, header-only:

• Art-Net receive: bbb::dmx::ofx::artnet_receiver wrapping

bbb::artnet::managed_node (standalone asio), per-universe buffers + stats.

• Show loading: bbb.dmx.fixture.profile.v1 / bbb.dmx.patch.v2 JSON via

the bbb-dmx C++ layer, resolved fixture views.

• Parameter evaluation: u8/u16/u24 sampling mirroring fixture_mapper

layout, shutter ranges tables (closed/open/strobe/pulse/random), semantic fixture state (color mixing RGB/CMY/W/A/UV, GDTF device-orientation beam direction, photometry beam angles).

• GDTF / MVR import: emits bbb.dmx JSON byte-identical to

bbb-dmx-utils (profiles with photometry/ranges, patch.v2 with coordinates: "gdtf", MVR Matrix -> position/rotation).

Usage

Header-only. In exactly one translation unit:

#define OFX_BBB_DMX_IMPLEMENTATION  // embeds miniz
include "ofxBbbDmx.h"

namespace lsim = bbb::dmx::ofx;

Clone with submodules (git clone --recursive): dependencies live under libs/ (bbb-artnet, standalone asio, bbb-dmx, vendored miniz with a one-line C++ compilation patch).

The coordinate model is the GDTF (DIN SPEC 15800) device-orientation convention adopted by bbb.dmx patch.v2: identity rotation = hanging device, beam rest = device -Z, pan about +Z, tilt about +X.
