Geometry Measure

Face Tangent

Creates Direction Vector that points from Face center to its edge

Order: Selects to which face edge vector points
Aligh to Direction: Choses direction that are closest to the Direction input

Direction: Direction
Corner Tangent: Creates Direction Vector that points from Face center to its vertex

Gradient Direction

Creates directional vector from gradient

Gradient: Gradient float input
Solenoidal: Divergence-free vector field

Mesh Ambient Occlusion

Calculates mesh ambient occlusion

Rays Samples: Amount of rays for sampling
Rays Angle: Angle that rays direction will be randomly rotated. Bigger angle will give more accurate results but with more noise
Seed: Random seed of the rays random direction
Blur Iterations: Smooth ambient occlusion map
External Mesh: Uses external mesh that rays will hit from main mesh to calculate ambient occlusion map

Attribute: Name of the thickness value attribute on point domain

Warning

Node can be really slow depending on mesh density and rays samples. You can “bake it” by applying geometry nodes modifier and the “ao” attribute will be stored on the mesh

Mesh Curvature

Calculates different types of mesh curvatures

Angle Unsigned

Angle Signed

Gaussian Curvature

Mean Curvature

Mesh Fresnel

Calculates mesh fresnel from camera point of view

Camera/Origin: Uses Camera or Custom origin location for calculating direction
Origin: Location of hte origin
Bias: Offset of the fresnel
Scale: Intensity of the fresnel
Exponent: Falloff of the fresnel

Mesh Island Measure

Calculates Area, Center, Area Center of Mass for each mesh island

Area: Area of the mesh
Center: Position from average vertex locations
Area Center of Mass: Position of Area Center of Mass

Mesh Measure

Calculates mesh total Volume, Area, Volume Center of Mass, Area Center of Mass

Volume: Volume of the mesh
Area: Area of the mesh
Volume Center of Mass: Position of Volume Center of Mass
Area Center of Mass: Position of Area Center of Mass

Mesh Tension

Creates Compression and Tension masks by comparing edge lenghts before and after mesh deformation

Rest Position: Position attribute that needs to be captured/stored before the mesh deformation happens. If using Armature use “rest_position” attribute by enabling it in properties/data tab

Strength Tension: Strength of the Tension mask
Strength Compression: Strength of the compression mask
Bias Tension: Offset of the tension values
Bias Compression: Offset of the compression values
Clamp: Clamps tension and compresions mask values between 0 and 1

Mesh Thickness

Calculates mesh thickness

Rays Samples: Amount of rays for sampling
Rays Angle: Angle that rays direction will be randomly rotated. Bigger angle will give more accurate results but with more noise
Seed: Random seed of the rays random direction
Normalize: Fits values between 0 to 1
Attribute: Name of the thickness value attribute on point domain

Warning

Node can be really slow depending on mesh density and rays samples. You can “bake it” by applying geometry nodes modifier and the “thickness” attribute will be stored on the mesh

UV Tangent

Creates directional vector from UV map on face domain

UV: UV map input for direction calculation
U/V: Choses UV map alightment axis to U or V
