Palazzo Spada. Facade of the Palazzo Spada.
Forced perspective gallery by Francesco Borromini. The corridor is much shorter, and the sculpture much smaller, than they appear. The palace accommodates a large art collection, the Galleria Spada.

When you assign a lens to a Rhino viewport using ViewportProperties, the resulting image you will see is what that lens would look like on a standard SLR 36mm x 24mm film gate camera.
If the viewport is not in a standard 1.5:1 aspect ratio, the minimum dimension will always be 24mm; the major dimension can be calculated by multiplying the minimum by the aspect ratio. Lens length is the distance from the focal node to the film plane. So with a 50mm lens, the focal node of the lens is, you guessed it, 50mm from the film plane. So with our standard Rhino viewport (and a SLR camera) the resulting view angle in plan view would be 39.6 degrees: Now, if we pop that same 50mm lens onto a motion picture camera, the film plane size changes to 24mm (this format is called Super35): So although you are keeping the same lens length, by changing your film size, you change your field of view.

This House by Roy Lichenstein Will Trip You Out. Located in the Sculpture Garden at the National Gallery of Art in Washington, DC is Roy Lichenstein’s famous House 1.
From a distance it simply appears to be a cartoon-ish facade of a simple 1-storey home. Peculiar but not trippy… However, as you approach you’ll begin to notice something very strange. What looks like an an outward facing home is indeed an inward facing sculpture. It’s quite mind bending and wonderful. Here’s the official description from the National Gallery of Art: Untitled. As mentioned in this previous post, I was very keen to see how AutoCAD could be used to help streamline the process of generating what I’ve now found out can be classified as anamorphic street art.
Leon Keer had mentioned that the technique dates back to Leonardo Da Vinci and – sure enough – Wikipedia agrees. As part of my research, I found the original video that inspired my interest in Leon’s work, which should help put this post in context: To make the process reasonably realistic – and to some degree replicate the approach Leon has taken in his projects – I managed to track down a free 3D model of a LEGO mini-figure.

Problems in the Perception of Linear Perspective. It is well know that the shape and size of objects visually changes if the object’s distance from the viewer and the position of the object change, but it needs specific theoretical training in the construction of perspective.
For these reasons, drawing three-dimensional objects on the picture plane demands not only knowledge of their external peculiarities, but also skills in matching the shape of objects to the peculiarities of visual perception which allows us to represent objects “truthfully”. However, this is one of the hardest tasks in drawing. It needs specific theoretical training in the construction of perspective. A review of textbooks and resource books on drawing published in different countries during the last 30 years reveals that a body of rules for linear perspective has evolved which is stable and interpreted similarly. Perspective sculpture geometry. Georges Rousse. Geometric Art By Georges Rousse Is Only Visible From One Angle. With his mind-bending perspective art, renowned artist Georges Rousse has proved that he is both an artist and a magician.
His amazing paintings create order out of what, from any angle but the right one, seems like total chaos. What seems like Photoshop is actually meticulously and carefully hand-painted artwork. With an architecture photographer’s eye, Rousse presents his work with a single photo taken from the single “perfect” angle that makes everything come together. The accompanying photos taken from the side, however, reveal just how chaotic and strange his works looked when viewed from the “wrong” perspective. Gödel, Escher, Bach. Gödel, Escher, Bach: An Eternal Golden Braid, also known as GEB, is a 1979 book by Douglas Hofstadter.
The tagline "a metaphorical fugue on minds and machines in the spirit of Lewis Carroll" was used by the publisher to describe the book. Illustrating Geometry with POV-Ray. POV-Ray has very good application in geometry learning, but this aspect is almost never utilized.
In this page, i give some examples showing how POV-Ray, or any other 3D Graphics engine, can be put to good use in understanding math theorems, understanding perspective in art, and learning physics of optics. Perspective in Visual Art In visual art, one important concept is perspectivity. Sculpture.org. A Question of Perspective: Sculpture by Charles Ginnever by Bruce Nixon Charles Ginnever was on vacation in Maine in 1993 when he went to work on a design that had already been in his mind for a while.
He started, as he often did, by tinkering with shapes cut from foam core; when he was done, he had produced an object that could stand freely in 11 positions. By the time a full-scale version of the piece was constructed at mid-decade, further adjustments enabled it to stand in 15 positions, and as a design it fully declared the sculptural concerns that had occupied him for more than 30 years. He called it Rashomon, borrowing the title from Akira Kurosawa’s film version of a novella by the early Japanese Modernist Ryunosuke Akutagawa: after a number of witnesses to a particularly heinous crime are questioned at length, police investigators are startled to find that each story differs from the others in some distinctive way.
Ginnever was not surprised. Ginnever’s Early Works Lost to Fire. Language agnostic - Calculating diminishing size in perspective. Mathematics of Perspective Drawing. Andrejs Treibergs University of Utah Department of Mathematics 155 South 1400 East, Rm. 233 Salt Lake City, UTAH 84112-0090 E-mail address:firstname.lastname@example.org Abstract. We present some mathematical ideas that occur in art and computer graphics. We touch upon the geometry of similar triangles, rigid motions in three space, perspective transformations, and projective geometry. We discuss computations behind rendering objects in perspective. Matrices - Perspective view and calculating based on it. Language agnostic - Calculating diminishing size in perspective. 3D projection. 3D projection is any method of mapping three-dimensional points to a two-dimensional plane. As most current methods for displaying graphical data are based on planar( pixel information from several bitplanes) two-dimensional media, the use of this type of projection is widespread, especially in computer graphics, engineering and drafting.
Orthographic projection When the human eye looks at a scene, objects in the distance appear smaller than objects close by. Orthographic projection ignores this effect to allow the creation of to-scale drawings for construction and engineering. Orthographic projections are a small set of transforms often used to show profile, detail or precise measurements of a three dimensional object. If the normal of the viewing plane (the camera direction) is parallel to one of the primary axes (which is the x, y, or z axis), the mathematical transformation is as follows; To project the 3D point onto the 2D point Weak perspective projection Which results in:
