WEMSelectPatches¶

MLModule¶

genre	`WEMProcessing`

package	`MeVisLab/Standard`

inherits from	`WEMProcessor`
keywords	`create`, `filter`

Purpose¶

The module WEMMDSSelectPatches allows for selecting patches of a WEM and creating new WEM from them.

Usage¶

Connect a WEM to the input field. Select the parameters described below to define which patches shall be copied to the new WEM.

Click Apply to create the new WEM (or alternatively enable the Auto Apply option).

Hitting the Clear button clears the output WEM (removes all patches).

Details¶

This module creates a new WEM based on the WEM/patches connected to its input.

Each time the Apply button is clicked, a new WEM is created that consists of all patches from the WEM connected to the input that match the criteria specified in the Selection Settings box.

The input WEM is not altered.

If the option Auto Apply is enabled, all parameter changes automatically trigger the creation of the new WEM.

Hitting the Clear button removes all patches from the output WEM.

Tips¶

If the Allow only one single output patch option is enabled, the Label and the Description attributes need to be set - otherwise they will be erased (or overwritten with the default - empty - value, respectively).

Visible Fields¶

Auto Apply¶

name: autoApply, type: Bool, default: FALSE¶: If checked, the module selects the output patch on changing any parameter.

Update Mode¶

name: updateMode, type: Enum, default: AutoUpdate, deprecated name: autoUpdate¶: Defines the update mode of this module.

Apply¶

name: apply, type: Trigger¶: If pressed, the module selects the output patch(es) on base of the paramters.

Clear¶

name: clear, type: Trigger¶: If pressed, the module clears its output.

Overwrite Label Description¶

name: overwriteLabelDescription, type: Bool, default: FALSE¶: If checked, label and description strings are set in the output WEM to Label and Description.

Label¶

name: label, type: String¶

Sets the label string to the output WEMPatch.

Available only if Allow only one single output patch is checked.

Description¶

name: description, type: String¶

Sets the description string to the output WEMPatch.

Available only if Allow only one single output patch is checked.

Selection Mode¶

name: selectMode, type: Enum, default: Patch Number¶: Defines which property of the input WEM patches shall be used for selection.

Values:

Title	Name
Patch Number	Patch Number
Patch ID	Patch ID
Primitive Value: LUT	PrimitiveValue: LUT
Primitive Value	PrimitiveValue

Selection Value¶

name: selectValue, type: String¶: Sets a value to selected the WEMPatch. The use of the value depends on Selection Mode.

Primitive Value Name¶

name: primitiveValueName, type: String¶: Sets a primitive value list name to select a WEMPatch, if Selection Mode is set to PrimitiveValue. A patch is selected if the mean PVL value is equal to the given value specified in Selection Value.

Allow only one single output patch¶

name: singleOutputPatch, type: Bool, default: TRUE¶

If checked, generally only one (the first, if more than one is available) patch is copied.

In this case it is posssible to edit the attributes of the patch(see Triangulate Patches).

Some options selectable for the Selection Value parameter result in only one patch being copied to the output WEM (e.g. Patch ID), others result in multiple patches being copied (e.g. Primitive Value: LUT).

Triangulate Patches¶

name: triangulatePatches, type: Bool, default: TRUE¶

If checked, all patches will be triangulate before adding them to the output WEM.

Remember: some WEM modules support arbitrary polygons, others do not.

Normally, all patches from the input WEM are copied to he output WEM “as they are” (i.e. with the same number and type of faces like in the input WEM).

Available only if Allow only one single output patch is not checked.
