HELP for DP21 (in htm format, taken from WPU21.HLP)


Here are the keyboard commands of Puertra. They take effect when done or after some seconds. If not, check if Lock Shift (Capitals) is set ‒it should not‒ and check if the Puertra Window is active ‒click on it with the mouse.

Many of these commands can be reached on the Puertra Window Menu too. The special commands used in Rige and Lattice editions appear at edition time.

Plane Transformations

          This section deals with movements and transformations of the whole figure across the plane or, according to the actual Spatial Surface across to it. The possible transformations are:

1. Change of the scale of a single figure, governed by '>' and '<' keys.

2. Change of the scale of a multiple figure, governed by the ')' and  '(' keys.

3. Displacements in horizontal and vertical directions, governed by the corresponding arrows.

Clockwise plane turning: each TE (Translation Element) in the positive (clockwise) direction, but holding their centers unmoved, Governed by 'v' key.

Block Displacements

 These commands affect the relative position of repeated TE, and their number. The formal relationship between contiguous TE’s is so important as their interior features. Therefore, the vertical and horizontal distances between them have an important repercussion on the general aspect of the whole figure. Let us comment each particular commands, usually in pairs 'increase-decrease':


Distances between contiguous TE:

     Horizontal                                       X                                               x

     Vertical                                           Y                                               y


Relative position of two vertical TE: We call it 'Lateral', the command '=' placing the TE rows in an alternate basis.

     Lateral                                            Z                                               z

     Bee Panel (hexagonal)                                             =


 Number of TE in the display: The TE cut by the display limits can be shown or not, the switching command being:

     Fill display limits                                                     %


The following commands also regulate the number of TE that appears around the central one, with respect to the display limits: the actual number of each one of the four parameters (down) are added to or subtracted from these limits:

     Right Num.TE                                Shft+k                                       Shft+l

     Left  Num.TE                                 Shft+j                                        Shft+h

     Up    Num.TE                                 Shft+i                                        Shft+u

     Down  Num.TE                              Shft+m                                      Shft+n

     Back to Display limits                                             Shft+o


This parameter controls the possible turning of TE when translated:

    Gyrated Translation                              Q                                              q

Spatial Transformations

The Rige and its Lattice can be considered to be in the three-dimensional space, rather than on a plane coinciding with the computer display. Therefore they can approach the spectator eye, they can go far away, move around the display, even disappear by crossing the display limits, turn on themselves. They became moving objects in space.

            These movements or transformations are controlled by the following commands:

Spatial Surface

The Rige is usually drawn on a plane; but it can be also done on a different surface. Puertra does it on a sphere, in which case four alternative projection methods of a plane on the sphere can be adopted. These methods are titled s1, s2, s3, s4. The user should try them out to choose the one he considers adequate. (s3 is taken by default). Commands:
