Need to have a 3D design created to to make it look like there's a hole in floor, from a certain angle (known as an anamorphic projection) for a result similar to the attached images. Hole in floor, and possibly tile floor only. No walls. The floor area is about 8x10 ft. The checkerboard design is for maximum contrast. The final design is to cut into a flat stencil.
Viewpoint still to be determined, the attached examples are just for reference, this would need to be designed to look right in the particular space, some details need to be determined.
Need file preferably in CorelDraw, but Illustrator, or other common vector formats are OK, or a Photoshop image is OK, I can convert it to vector if needed. No autocad.
