IN:3 OUT:3

SUMMARY

Nexus Postprocess takes the three outputs of a Nexus solver (Geometry, Constraints and Target Geometry) and finishes the result for display. It fuses welded seams into one connected surface, smooths the mesh with blur iterations and subdivides it with crease control.

The Visualize page colors collided points and draws guides for thickness, pins, stitches and attachments. Property colors the mesh through a ramp by a constraint measure such as stretch or bend stress, stretch ratio, plastic flow, volume change or broken constraints, and Output Attributes keeps the chosen measures as point attributes for shading or further processing.

PARAMETERS

PAGEOperations

Apply Weld	Applyweld	Fuse welded points into their weld root, so welded seams become one connected surface.
Blur Iterations	Bluriterations	Number of smoothing iterations to apply to the mesh. Set to 0 to disable smoothing.
Blur Strength	Blurstrength	Sets the blend between the original and smoothed positions for each iteration.
Depth	Depth	Number of subdivision levels to apply to the mesh. Set to 0 to disable subdivision.
Crease Weight	Creaseweight	Controls edge sharpness during subdivision. Higher values preserve hard edges.
Simple Coefficients	Simplecoeffs	Uses simplified subdivision coefficients for faster computation.

PAGEVisualize

External Collisions	Collisions	Display the points that collide with external geometry.
[+]Color	Collisionscolor	Sets the color of the external collision display.
Self Collision	Selfcollision	Display the points that collide with the geometry itself.
[+]Color	Selfcollisioncolor	Sets the color of the self collision display.
Thickness	Thickness	Display a sphere at each point, sized by its thickness.
[+]Color	Thicknesscolor	Sets the color of the thickness display.
Pin to Target	Pintotarget	Display the hard and soft pinned points.
[+]Color	Pintotargetcolor	Sets the color of the pin to target display.
Stitch Points	Stitchpoints	Display the stitch constraints as lines.
[+]Color	Stitchcolor	Sets the color of the stitch display.
Attach to Geometry	Attachtogeometry	Display the constraints that attach points to collision geometry, as lines.
[+]Color	Attachtogeocolor	Sets the color of the attach to geometry display.
Radius	Radius	Sets the size of the pin to target display points.
[+]Property	Property	The constraint property that colors the geometry, mapped through the color ramp from Min Value to Max Value.
Display Property	Displayproperty	Show the selected property visualization on constraints.
Min Value	Minvalue	Sets the property value mapped to the start of the color ramp.
Max Value	Maxvalue	Sets the property value mapped to the end of the color ramp.

PAGEOutput Attributes

Stretch Stress	Stretchstress	Output StretchStress: the largest force on the point's stretch constraints.
Bend Stress	Bendstress	Output BendStress: the largest force on the point's bend constraints.
Stretch Distance	Stretchdistance	Output StretchDistance: the average stretch of the point's distance constraints from their rest length.
Stretch Ratio	Stretchratio	Output StretchRatio, the average length over rest length of the point's distance constraints. 1 means at rest.
Bend Angle	Bendangle	Output BendAngle: the average bend of the point's bend constraints away from their rest angle, in degrees.
Stretch Plastic Flow	Stretchplasticflow	Output StretchPlasticFlow: the average plastic deformation of the point's stretch constraints.
Bend Plastic Flow	Bendplasticflow	Output BendPlasticFlow: the average plastic deformation of the point's bend constraints.
Volume Stress	Volumestress	Output VolumeStress: the pressure force of the volume the point belongs to.
Volume Distance	Volumedistance	Output VolumeDistance: how far the point's volume is from its rest volume.
Volume Ratio	Volumeratio	Output VolumeRatio, the point's volume over its rest volume. 1 means at rest.
Broken Constraints	Brokenconstraints	Output Broken: the number of broken constraints at each point.
