ABSTRACT:
An artist's drawing device for maintaining a constant three-dimensional perspective while rendering a subject or object. The drawing device includes a first visually-defined perimeter of a planar geometric figure having a first size, a second visually-defined perimeter of a planar geometric figure having proportionate dimensions but a larger overall size than the first planar figure, and means for seeing the first and second planar geometric perimeters in a concentric spaced relation along the artist's line of sight, the smaller geometric perimeter being closer to the artist. The artist secures the device in position for viewing a subject or object therethrough such that the perimeter of the second geometric figure is eclipsed from sight by the perimeter of the first geometric figure. This fixes the artist's perspective on said subject/object in all of three dimensions, and any deviation from said fixed perspective becomes immediately apparent when the state of eclipse is lost.
