Example 6 with Plane

use of maspack.matrix.Plane in project artisynth_core by artisynth.

the class EditingAgent method intersectViewPlane.

/**
 * Intersect a ray with a view plane defined by the current eye direction and
 * a reference point.
 */

    return res;
}

Example 7 with Plane

use of maspack.matrix.Plane in project artisynth_core by artisynth.

the class EditingAgent method intersectClipPlane.

/**
 * Intersects a ray with a viewer clip plane and returns the corresponding
 * point. If there is no intersection because the plane is perpendicular to
 * the eye direction, then null is returned.
 */

    Point3d res = new Point3d();
    Plane plane = new Plane();
    clipPlane.getPlane(plane);

        return null;
    } else {
        return res;

use of maspack.matrix.Plane in project artisynth_core by artisynth.

the class ParticlePlaneConstraint method transformGeometry.
