Filters

Filters change the simulation on the server. You set the options in the sidebar. The server runs them and sends back a new surface, which appears as a child under Source.

Which filter to use

You want to… Choose
Show displacement, a mode shape, or an exaggerated deformation Warp
Look inside the model, or cut it on X, Y, or Z Planar clip
Hide the mesh without adding a new result Stage visibility
Keep only a region you draw on screen Extract cells or Extract points, under Tools along the top — separate from the Filters card

Warp

  1. Open Filters and select Warp.
  2. In Filter properties:

- Warp mode — None, Warp by vector, or Warp by scalar

- Warp field — a field on the source

- Warp scale — how far the displacement is exaggerated. A small scale can look like no change

  1. The server builds the warped surface.
  2. A Warp row appears in the scene tree.

Vector mode uses a vector field. Scalar mode uses a single value per point and needs a scale before the shape reads clearly.

Planar clip

  1. Select Planar clip in Filters.
  2. In Filter properties:

- Enable planar clip — turn the cut on or off

- Clip axis — X, Y, or Z

- Clip offset — where the plane sits. 0 is the center of the model. Negative and positive move it along the axis

- Show clip plane in viewport — a plane you can drag

  1. Drag the plane in the view, then release. The server applies the new position.
  2. A Clip row appears when the surface is ready.

Use the eye icons to compare the full source with the cut.

Stage visibility

Stage visibility shows or hides the mesh without creating a Clip or Warp row. Use the eye icon on a scene-tree row when you only want to hide that one result. Cameras, lights, and guides are not in this control yet.

While the server works

On a volume, warp and clip are applied on the server:

  • You may see *Applying clip filter* or *Applying warp filter*.
  • Wait until the scene tree and the view refresh before you change the settings again.
  • Move a slider, then pause. The server applies the value where you left it.

Changing color, opacity, or display style does not rebuild the mesh. Those stay in the browser.

Tools along the top

Control What it does
Align model Camera and display style. It does not filter the simulation
Extract cells / Extract points Draw a region, then the server keeps the cells or points inside it
Point probe / Cell probe Read a field value where you click. The mesh is not rebuilt

Editing a filter you already made

Select the Clip or Warp row. Filter properties shows that result’s settings, and a change rebuilds the same row.

Select Source when you want the filter list again, so you can add another filter beside the ones you have.

Troubleshooting

What you see Likely cause
The Filters card is hidden Nothing is loaded yet
The overlay never finishes The server is disconnected or busy. Check Infrastructure
The view is empty after a clip The source is hidden, or the plane misses the mesh. Move the offset
Warp looks unchanged The scale is very small, or the field is the wrong one
