Examples of com.ardor3d.intersection.PickData

com.ardor3d.intersection.PickData
PickData contains information about a picking operation (or Ray/Volume intersection). This data contains the mesh the ray hit, the triangles it hit, and the ray itself.

            return;
        }


        // act on drag
        final PickData pickData = _results.getPickData(0);
        final Spatial picked = (Spatial) pickData.getTarget();
        if (picked instanceof Mesh && pickData.getIntersectionRecord().getNumberOfIntersections() > 0) {
            final PrimitiveKey key = pickData.getIntersectionRecord().getIntersectionPrimitive(0);
            ((Mesh) picked).getMeshData().getPrimitiveVertices(key.getPrimitiveIndex(), key.getSection(),
                    new Vector3[] { _calcVec3A, _calcVec3B, _calcVec3C });
