继承 TShape



A box with faces perpendicular to the axes.
It has 6 parameters:
  - name:       name of the shape
  - title:      shape's title
  - material:  (see TMaterial)
  - dx:         half-length of the box along the x-axis
  - dy:         half-length of the box along the y-axis
  - dz:         half-length of the box along the z-axis
