Example 6 with IsRenderable

use of maspack.render.IsRenderable in project artisynth_core by artisynth.

the class ImagePlaneProbe method getRadius.

public double getRadius(ModelComponent e) {
    double radius = 1.0;
    if (e instanceof IsRenderable) {
        IsRenderable r = (IsRenderable) e;
        Point3d max = new Point3d(-inf, -inf, -inf);
        Point3d min = new Point3d(inf, inf, inf);
        r.updateBounds(min, max);
        if (max.x != -inf) {
            // then the renderable provided bounds, so use to
            // compute radius
            Vector3d vdiag = new Vector3d();
            vdiag.sub(max, min);
            radius = vdiag.norm() / 2;
