CuttingPlane

class cee.ug.CuttingPlane()

Specification of a cutting plane (both parameters and attributes) in a RemoteModel

Use this object to control the position, settings and visual attributes of a cutting plane. The position of the cutting plane is defined with point and normal You can map a scalar result onto the cutting plane with mapScalarResultId and show vectors sampled in a regular grid with mapVectorResultId The spacing of this regular grid is defined with vectorGridSpacing

You can specify whether to clip the model in the cutting plane’s plane with clipping show the intersected element mesh with showElementMesh and set its opacity

Please note that cutting planes are more that just geometric clipping planes. They intersect the volume elements and produce a surface onto which results can be mapped.

To create a cutting plane, use RemoteModel.addCuttingPlane

Example: Create two cutting planes:

var modelDir = myModel.modelDirectory;

// Find basis for position and map scalar result
var bb = myModel.getBoundingBox();
var halfExtent = bb.getExtent().x/2;
var mapScalarId = -1;

if (modelDir.scalarResultArray.length > 0) {
    mapScalarId = modelDir.scalarResultArray[0].id;
}

// Create plane 1
var plane1 = myModel.addCuttingPlane();
plane1.point = cee.Vec3.add(bb.getCenter(), new cee.Vec3(0.5*halfExtent, 0, 0));
plane1.normal = new cee.Vec3(1,0,0);
plane1.mapScalarResultId = mapScalarId;

// Create plane 2
var plane2 = myModel.addCuttingPlane();
plane2.point = bb.getCenter();
plane2.point = cee.Vec3.sub(bb.getCenter(), new cee.Vec3(0.5*halfExtent, 0, 0));
plane2.normal = new cee.Vec3(1,0,0);
plane2.mapScalarResultId = mapScalarId;
plane2.showElementMesh = true;

// Set model to outline to show the cutting planes
myModel.setDrawStyleAllParts(cee.ug.DrawStyle.OUTLINE);

Accessors

cee.ug.CuttingPlane.clipping

Whether the model should be clipped. If true, the model will be clipped at the cutting plane position

cee.ug.CuttingPlane.computeFromVisibleParts

If set to true, the cutting plane will be computed from only the visible parts. Any part that is not visible will not contribute to the cutting plane.

cee.ug.CuttingPlane.crinkleCutSurface

Specify if the cutting plane should show a crinkle cut surface.

If enabled, the cutting plane surface will be the combined surface of all elements intersected by the cutting plane. So the cutting plane will show the tesselation of all intersected elements.

This is useful for inspecting and visualizing the mesh of a volume element model.

The default is false.

cee.ug.CuttingPlane.eyeLift

The eye lift mode to use for this cutting plane.

Eye lift can be used when facing z fighting issues (triangles rendered in the same plane). By applying eye lift to one part, it will be moved slightly towards the eye, resolving the z fighting issues. The current version offers 3 eye lift factors to choose from.

cee.ug.CuttingPlane.highlight

Whether the cutting plane should be highlighted.

cee.ug.CuttingPlane.id

The id of the cutting plane. This is assigned by the system when you call RemoteModel.addCuttingPlane and is used to identify the cutting plane.

cee.ug.CuttingPlane.isPrecomputed

Is true if the cutting plane is precomputed and cannot be changed

cee.ug.CuttingPlane.lighting

Toggle lighting of the cutting plane on/off.

cee.ug.CuttingPlane.mapScalarResultId

The id of the scalar result to show on the cutting plane. This id must refer to one of the scalar results in ModelDirectory.scalarResultArray You can change the settings for the scalar in the ScalarSettings object.

Set to -1 to show no scalars on the cutting plane.

cee.ug.CuttingPlane.mapVectorResultId

The id of the vector result to show on the cutting plane. This id must refer to one of the vector results in ModelDirectory.vectorResultArray The vectors are shown in a regular grid. The spacing of this grid can be set with vectorGridSpacing The settings for the vector arrows can be changed with the VectorSettings object.

Set to -1 to show no vectors on the cutting plane.

cee.ug.CuttingPlane.normal

The normal of the cutting plane. Defines its orientation.

cee.ug.CuttingPlane.opacity

Opacity of the cutting plane. 0.0 means fully transparent (invisible), 1.0 means fully opaque.

cee.ug.CuttingPlane.point

A point in the plane. Together with the normal property this defines the plane that the cutting plane is in.

cee.ug.CuttingPlane.projectVectorsOnPlane

If true, the regular grid vectors are projected onto the cutting plane, making all the vectors parallel to the cutting plane surface.

The default is false.

cee.ug.CuttingPlane.showElementMesh

Whether the intersected element mesh should be rendered. If true, the mesh resulting from the intersection of the cutting plane with the element model will be overlaid on the cutting plane.

cee.ug.CuttingPlane.showSurface

Whether the surface of the cutting plane should be visible.

The default is true.

cee.ug.CuttingPlane.surfaceColor

The color of the cutting plane surface if not showing a result and useSourcePartColor is false

cee.ug.CuttingPlane.useSourcePartColor

If set to true, the cutting plane will be colored by the source part, so this plane will end up with different colors based on the color of the parts the cutting plane intersects

cee.ug.CuttingPlane.vectorGridSpacing

The spacing of the vectors shown on the cutting plane. The vector arrows are resampled into a regular grid before being rendered on the cutting plane. This property defines the spacing between each vector arrow on the cutting plane. The value is relative to the current extent of the model.

The default is 0.02

cee.ug.CuttingPlane.visible

Visibility of the cutting plane. Use this to show or hide a cutting plane in the 3D Viewer.
