Vessels
vessel_mesh builds a named lower-limb artery or vein. Connected centerlines preserve the major arterial branches and venous junctions.
The solids live in extensions/humanoid/skeleton/leg/vessels/. add_leg can draw them with VESSELS. See Leg.
This is not a three.js port. See Extensions.

var person = HumanoidSpec(Length(6.0, FOOT), MALE)
var artery = vessel_mesh(person, FEMORAL_ARTERY)side picks RIGHT or LEFT. A right leg is the default.
The solids live in the leg frame. The origin is the tibiofemoral joint line. Plus y is proximal. Plus x is body-right. Plus z is anterior.
The labeled set follows the standard adult lower-limb courses.
| Part | Role |
|---|---|
FEMORAL_ARTERY |
Femoral triangle through the adductor canal and hiatus. |
POPLITEAL_ARTERY |
Adductor hiatus through the posterior knee to the tibial branch point. |
ANTERIOR_TIBIAL_ARTERY |
Branch point through the proximal interosseous route and anterior leg. |
TIBIOPERONEAL_TRUNK |
Short common segment from the popliteal split to the posterior/fibular split. |
POSTERIOR_TIBIAL_ARTERY |
Tibioperoneal split through the deep posterior leg and behind the medial malleolus. |
FIBULAR_ARTERY |
Tibioperoneal split along the deep posterior fibula. |
PERONEAL_ARTERY |
Compatibility name for FIBULAR_ARTERY. |
FEMORAL_VEIN |
Popliteal continuation through the adductor hiatus to the groin. |
POPLITEAL_VEIN |
Deep-vein confluence through the posterior knee. |
GREAT_SAPHENOUS_VEIN |
In front of the medial malleolus, along the tibia's medial border and the medial knee, then femoral vein. |
SMALL_SAPHENOUS_VEIN |
Posterior lateral malleolus and calf, then popliteal vein. |
The femoral artery ends exactly where the popliteal artery starts. The anterior tibial artery and tibioperoneal trunk share the popliteal split.
The trunk then splits into posterior tibial and fibular arteries. The saphenous veins end exactly on their deep-vein junctions.
Physical radii drive distance, containment and analytic mass. The mesh alone applies a diagrammatic minimum radius for visibility.
The model ends at the ankle. It omits profunda, genicular, plantar, dorsalis-pedis and paired distal deep-vein branches.
is_artery returns True for the five named arteries.
arterial_tissue() and venous_tissue() hold wet density 1.06 g/cm³ as a named whole-blood template. Water fraction is 0.80.
Arterial circumferential modulus is 0.50 MPa. Venous circumferential modulus is 0.30 MPa. Poisson's ratio is 0.45.
Water fraction is metadata. Mass uses wet density times envelope volume. Do not scale by one minus water fraction again.
These values are named research metadata. This extension does not implement a constitutive model.
