Platonic Solids
From Ultrafractal Wiki
Platonic Solids is a Transformation in sam.ufx.
Contents |
What is it?
This transformation draws the five Platonic Solids. These are the five polyhedron which admit one type of regular polygons as sides. They are the tetrahedron, the cube, the octahedron, the dodecahedron and the icosahedron. Some pseudo 3D tools such as lightning and a kind of fog effect are available. The object rotation/translation part has been borrowed to Frederik Slijkerman's well known 3D mapping, so these parameters work the same.
Parameters
Polyhedron
Choose your polyhedron...
Side Type
The sides can be either solid, "framed" (the inside is transparent) or "unframed" (the border is transparent). The Mix types set some sides to "Frame" and other ones to "Solid".
Mode
- Mapping : The standard mode. The image is mapped on the sides of the polyhedron.
- Lightning : It should be used on a "Pixel" formula with the "Gradient" coloring in Standard.ucl. A black and white gradient is appropriate. It simulate the lightning produced by a source set at the point defined by the "Light Source (x/y/z)" parameters. You may have to change the color density to get a convincing result.
- Ghost : It should also be used on "Pixel" with the "Gradient" coloring. The distance to the observer determine the color of the pixel. With some practice, it can be used to give a nice volume impression. It could also produce a kind of fog effect.
- Sides A/B/C/D/E : Allow you to color some tiles separately (on some polyhedrons, not all of these parameters will have an effect).
X/Y/Z Rotation/Translation
These parameters are the same as in the "3D Mapping" transformation. The x axis is horizontal, the y axis vertical and the z axis perpendicular to the screen.
Mapping Center/Rotation/Magnification
Define which part of the original image will be mapped on the sides.
Frame Width
The frame width for the "Frame", "Unframe" and "Mixt" side types.
Light Source (x/y/z)
The location of the light source for the "Lightning" mode.
