Triangulated Mesh Ribbon Tab

Context-sensitive tab — appears when the Triangulated Mesh context is active.

Commands available on the Triangulated Mesh ribbon tab, grouped by panel.

Attribute​

Facies Attribute​

A group of two controls:

  • Create — Add new facies attribute
  • Target — Target facies attribute

Radius​

Tooltip: Attribute brush radius (world units)

Radius of the sphere used by Paint Attribute. The texture brush has its own Radius on the Texture Overlay panel.

Paint Attribute​

Tooltip: Paint mesh attribute

Paint the active facies attribute onto mesh vertices inside the brush sphere.

Facies​

A group of three controls:

  • Facies — Add a new facies
  • Apply — Apply to selected vertices
  • Active facies (drop-down) — Active facies

Show Attribute​

Tooltip: Colour the mesh by its active attribute

Colour the mesh by the active attribute layer's ramp. This is the per-vertex attribute, not the painted texture overlay; while it is on, Display Blend decides how much of the texture shows through.

Texture Overlay​

Paint Texture​

Tooltip: Paint mesh texture

Paint colour directly onto the mesh texture at the cursor position.

Radius​

Tooltip: Texture brush radius (world units)

Radius of the texture-paint brush, in world units. Separate from the attribute brush radius on the Attribute panel.

Hardness​

Tooltip: Fraction of the brush painted at full strength

How much of the brush is painted at full strength before the falloff starts. Discrete facies layers write hard at the half-strength contour, so this shapes their footprint rather than fading it.

Opacity​

Tooltip: Stroke opacity for continuous layers

Stroke opacity for continuous (float) layers. Discrete facies layers write their value outright and ignore this.

Eraser​

Tooltip: Erase painted texels

Clear paint back to the underlying texture instead of adding to it.

Magic Wand​

Tooltip: Fill by texture colour instead of brushing

Click to fill outwards from that point for as long as the texture colour stays within Tolerance of it. The fill stops at the edge of the UV island under the cursor, so a face split across several islands or texture pages needs one click per piece.

Tolerance​

Tooltip: How far the wand fill may stray from the seed colour

How different from the clicked colour a texel may be and still be filled. Low values follow a tight colour band; high values on a low-contrast image will run until the texel limit stops them.

Track​

Strength​

Tooltip: Power of the attribute tracking

The higher the power the more impact larger differences have (weighting = power(difference,tracking_power)

Balance​

Tooltip: Balance between attributes and distance

The higher the balance (0-1) the more impact the distance between the vertices has.

Distance​

Distance Metric

Tracker​

Tooltip: Auto-track a surface

Auto-track a surface across the mesh using the active attribute and tracking parameters.

Dropdown items:

  • Track Initial Value — Track initial attribute value
  • Track Minimum — Track local minimum
  • Track Maximum — Track local maximum

Drainage​

Tooltip: Trace drainage

Trace a drainage pathway downslope

Control Points​

GCP​

Tooltip: Add a ground control point

Add tiepoints (and matching targets) used to constrain mesh registration.

Dropdown items:

  • Add Tiepoint — Add a tiepoint
  • Add Tiepoint and Target — Add a tiepoint and target

Corrections​

From GCP​

Tooltip: Correct from GCPs

Apply a corrective transform to the active mesh computed from its tiepoints.

Dropdown items:

  • From GCP — Correct from GCP only with no scaling
  • From GCP with Scaling — Correct from GCP only with scaling enabled

From Orientation​

Tooltip: Correct from orientation

Apply a corrective transform computed from the active mesh's orientation control points.

From Both​

Tooltip: Correct from GCPs and orientation

Apply a corrective transform that combines tiepoints and orientation control points.

Rescale​

Tooltip: Rescale the mesh

Apply a scale correction to the active mesh based on its tiepoints.

Rescale GCP​

Tooltip: Rescale from GCPs

Rescale the mesh from tiepoints, isotropically or anisotropically.

Dropdown items:

  • Rescale From GCP — Rescale From GPC
  • Anisotropic Rescale GCP — Anisotropic rescale from GCPs

Lock Position​

Tooltip: Lock the mesh position

Lock the active mesh against further corrections or transforms.

Translate​

Tooltip: Translate or rotate the mesh

Apply a translation or rotation transform to the active mesh.

Dropdown items:

  • Along X Y or Z — Translate along an axis
  • Along Vector — Translate along a vector
  • Rotate — Rotate the mesh

Undo Transform​

Tooltip: Undo last transform

Undo the most recent translate or rotate transform applied to the mesh.

Redo Transform​

Tooltip: Redo last transform

Redo a translate or rotate transform that was previously undone.

Textures​

Add Texture​

Add a projective texture to the mesh

Edit​

Edit a projective texture

Iterative Closest Point​

See ICP Alignment.

ICP​

Tooltip: Run iterative closest point

Align the active mesh to a mesh or point cloud shown in the view. With several shown, a menu asks which. Click it again during a run to stop.

Split View​

Tooltip: Toggle split view

Split the 3D view into two panes side by side, each with its own viewpoint. In the OpenGL view the second pane shows only the active mesh.

Overlay​

Tooltip: Overlay reference mesh

Has no effect on what is drawn, and the Vulkan view does not offer it.

Sampling​

Tooltip: ICP sampling fraction

Fraction of mesh vertices sampled when running ICP (lower values run faster).

Keep Closest %:​

Tooltip: Share of correspondences kept

ICP keeps this percentage of its correspondences, the closest ones, and drops the rest (100 keeps them all). It already down-weights outliers, so lower this only to drop the farthest pairs outright.

Max Distance​

Tooltip: Maximum correspondence distance

Maximum distance allowed between a pair of corresponding ICP points.

Tooltip: Show correspondence links

A toggle kept per mesh. Neither 3D view draws these links.

Use Tiepoints​

Tooltip: Use tiepoint centroids

Seed ICP using the centroids of existing tiepoints to constrain the initial alignment.

Point to Plane​

Tooltip: Point-to-plane ICP

Minimise distance from each source point to the closest target plane (faster convergence on smooth surfaces). Against a point cloud, the target plane is the one through each of its points' nearest neighbours.

Point to Point​

Tooltip: Point-to-point ICP

Minimise distance between corresponding source and target points (classic ICP).
