Detailed Description

Remove parts of a mesh that is on the back side of a plane. Replaces removed parts with triangles aligned with the plane. Link the camera property to move the camera along the plane, or to align plane with view direction. Coordinates are specified in world space.

Supports SimpleMesh and BasicMesh

Inports

inputMesh Input mesh

Outports

clippedMesh Clipped output mesh
clippingPlane Plane used for clipping the mesh in world space coordinate system

Properties

Move Plane Point Along Normal Enable slider for adjusting plane position
Plane Point Along Normal Move Offset plane along its normal
Move Camera Along Normal Moves camera along with plane movement.
Plane Point World space space position of plane
Plane Normal ... World space space normal of plane
Camera Camera used for moving or aligning plane.
Align Plane Normal To Camera Normal Aligns plane normal with camera
Enable clipping Pass through mesh if disabled.

Member Function Documentation

◆ clipGeometryAgainstPlane()

std::shared_ptr< Mesh > inviwo::MeshClipping::clipGeometryAgainstPlane	(	const Mesh *	mesh,
		const Plane &	plane
	)

protected

Clip mesh against plane. Replaces removed parts with triangles aligned with the plane.

Exceptions

Exception if mesh is not a SimpleMesh or BasicMesh

Parameters

mesh	to clip
plane	in world space coordinate system.

◆ process()

void inviwo::MeshClipping::process ( )

overrideprotectedvirtual

Deriving classes should override this function to do the main work of the processor. This function is called by the ProcessorNetworkEvaluator when the network is evaluated and the processor is invalid, i.e. some of its inports or properties has been modified, and is ready i.e. all non optional inports have valid data.

See also: ProcessorNetworkEvaluator; Inport; Property

Process overview

Take axis-aligned bounding box (AABB) mesh as input.
Call clipGeometryAgainstPlane(...) with input and plane_ as arguments
Extract and store an edge list from the input mesh's triangle list
Start with an empty outputList and empty outputEdgeList. Iterate over the edge list extracted from the triangle list and check each edge against the clip plane. Store verts and edges in outputList and outputEdgeList as you go.
Use outputEdgeList and, indirectly, outputList to rebuild a correctly sorted triangle strip list.
Build new mesh from the triangle strip list and return it.

Reimplemented from inviwo::Processor.
