intersects

fun PartitionedMesh.intersects(box: Box, meshToBox: AffineTransform): Boolean

Returns true when a PartitionedMesh intersects with a Box.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToBox transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun Box.intersects(mesh: PartitionedMesh, meshToBox: AffineTransform): Boolean

Returns true when a Box intersects with a PartitionedMesh.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToBox transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun Parallelogram.intersects(
    mesh: PartitionedMesh,
    meshToParallelogram: AffineTransform
): Boolean

RReturns true when a Parallelogram intersects with a PartitionedMesh.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToParallelogram transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun Vec.intersects(mesh: PartitionedMesh, meshToPoint: AffineTransform): Boolean

Returns true when the point (a Vec) intersects with mesh. meshToPoint transforms the coordinate space of mesh to the coordinate space that the intersection should be checked in (that of the point). All points along the boundary of the mesh and the meshs interior are considered for intersection.

Performance note: it is expensive to apply a transform to a mesh. To avoid unnecessary calculations, the inverse of meshToPoint is used to perform the mathematically equivalent intersection of the point in mesh’s object coordinates.

intersects

fun Segment.intersects(
    mesh: PartitionedMesh,
    meshToSegment: AffineTransform
): Boolean

Returns true when a Segment intersects with a PartitionedMesh.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToSegment transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun Triangle.intersects(
    mesh: PartitionedMesh,
    meshToTriangle: AffineTransform
): Boolean

Returns true when a Triangle intersects with a PartitionedMesh.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToTriangle transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun PartitionedMesh.intersects(
    parallelogram: Parallelogram,
    meshToParallelogram: AffineTransform
): Boolean

Returns true when a PartitionedMesh intersects with a Parallelogram.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToParallelogram transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun PartitionedMesh.intersects(point: Vec, meshToPoint: AffineTransform): Boolean

Returns true when the PartitionedMesh intersects with point. meshToPoint transforms the coordinate space of mesh to the coordinate space that the intersection should be checked in (that of the point). All points along the boundary of the mesh and the meshs interior are considered for intersection.

Performance note: it is expensive to apply a transform to a mesh. To avoid unnecessary calculations, the inverse of meshToPoint is used to perform the mathematically equivalent intersection of the point in mesh’s object coordinates.

intersects

fun PartitionedMesh.intersects(
    segment: Segment,
    meshToSegment: AffineTransform
): Boolean

Returns true when a PartitionedMesh intersects with a Segment.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToSegment transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun PartitionedMesh.intersects(
    triangle: Triangle,
    meshToTriangle: AffineTransform
): Boolean

Returns true when a PartitionedMesh intersects with a Triangle.

Note that, because it is expensive to apply a transform to a mesh, this method takes a meshToTriangle transform as an argument. This transform maps from the PartitionedMesh's coordinate space to the coordinate space that the intersection should be checked in.

intersects

fun PartitionedMesh.intersects(
    other: PartitionedMesh,
    thisToCommonTransForm: AffineTransform,
    otherToCommonTransform: AffineTransform
): Boolean

Returns true when a PartitionedMesh intersects with a PartitionedMesh.

Note that, because it is expensive to apply a transform to a mesh, this method takes two AffineTransform objects: thisToCommonTransForm and otherToCommonTransform. These transforms map from the respective PartitionedMeshs' coordinate spaces to the common coordinate space that the intersection should be checked in.
