Therefore, as t changes from 0 to 1, the transformed curve C1(u) sweeps out a surface. The curve C1(v) may be rotated and scaled, so for each t in the domain of curve C2(v), curve C1(u) is moved to the point C2(t), with possible rotation and/or scaling. The swept surface is the surface generated by moving curve C1(v) along curve C2(u). Swept Surfaces are created by two curves C1(u) and C2(v).The image below shows four possible types of continuity:įrom The Inventor Mentor: Programming Object-Oriented 3D Graphics with Open Inventor™, Release 2 Continuity is defined when the endpoints of two curves meet.What this means is that our visual system assumes that we are viewing something from a non-accidental point of view, and we believe what we see unless there is information to the contrary. External lines are viewed as the boundary of the shape.Acute and obtuse angles are interpreted as 90° angles in perspective.Continuous straight lines are interpreted as continuous straight lines.Two-dimensional parallel lines should be interpreted as three-dimensional parallel lines.Two-dimensional straight lines should be interpreted as three-dimensional straight lines.The Generic View Principle is our assumption that we are viewing images from a generic, or general, view. given the chance to interpret a drawing or image as three-dimensional, we will. As our visual system automatically assigns depth to each point in an image. The 2D drawing above is not impossible, but our three-dimensional interpretation of it is. In support of this release the band will once again be touring around the United States, releasing various thematic videos, and a Cassette Box Set Compendium which features six hour long tapes of all of the band’s released material, and some unreleased material spanning 1998 - 2007.A form is called impossible when our mind tries to interpret it as a three-dimensional object in Euclidean space, with straight edges and planar faces, instead of interpreting it as a two-dimensional object drawn on the paper plane.Ī family of impossible figures studied by knot theory, by Corinne Cerf It is simultaneously a celebration of the triumph of virtual technologies, and a wake for the end of our old and sacred biology.
It is in fact a “Secret Operation”, but also a call to humanity to stop consuming art, and just “Make Art” instead. It is not right out there in the open for all to see, and yet it is. The message is hidden in the dirt, the excrement, the unconscious, and written in a secret language - “Dreamspeak”. The message concerns mushrooms and gurus and vegetable wisdom - “Let The Mushroom Teach”. The message concerns the art of magick and making things happen in conformity with the Will - “Hey! Let’s Make It Happen”. The title of this album is a sigil (but you can call it The Impossible Shapes), a potent symbol of desire - the desire to quickly spread a message to all of humanity, as revealed by the various entities encountered in dreams, visions, and astral travel. Eventually the band ended up recording these 11 songs to extra sticky analog tape in their own makeshift warehouse studio on South Walnut street in Bloomington. These recordings have been through a lot - starts and stops and false starts and falser stops.

Songwriter Chris Barth translates a cosmological view as psychedelic nursery rhymes or rock n roll cracked into free form strata. At the root these four long-hairs are a pop band - kinda like how Byrds became a meta group - who’ve been strained through British folk as well as the whole post/beat/mystic literate gob. This album is their pinnacle song mound that could have been issued by Zapple, if times had been different.
With this release the band has recorded songs which were flushed out over many live performances over many tours all across the globe. The Impossible Shapes have been merrily musickmaking - mostly under the radar - for a decade now.
