i wanted to find out if i was able to use Digits superduper interpolation script contained here (http://www.cyber-webs.com/zbrush/ztools/widgets/Digit_Widget_Script.zip) for something "on purpose" this time and decided i’ll give an earth/moon/phases pic a try (i assume the distance-ratio to be mucho perverted and the pic to be everything but a realistic representation but for those who are interested in exploring the script but have not done so up-to-now i’ll give some settings below anyway).
:qu: as far as i get it, the moon’s "shape" as we see it from down here is determined by the partition that earth’s shadow is covering upon it’s surface. is there a way to simulate this in a setting like this one? which type of light (i had no luck with the sun and the radius for point or glow light was too short to reach the moon) would you use? hmm, as i think about it, i believe that it can’t be done within one pic as the main light has to be shifted, right? any hints would be highly appreciated!
so here is what i did using Digits interpolate script for doing an orbit like the one above:
:b4: i loaded the Digits Widgets Interpolates.txt script out of the Widgets folder.
:b4: on a layer of its own i "created" earth in a second :) by applying texture 24 to a sphere. by default it’s center is set at z-depth 0. while in transformation mode i hit the "use current" button in the © davey "nose pointer" section of the script’s commands in order to make the moon face the earth in the same way from all directions (as i think that is what it does in "reality", too). (PS: in other cases it might be appropriate to leave this step out and instead use the rotate-functions, that Digits implemented in his fantastico script... in order to do so you might want to set the objects at mark1 and mark2 and the attractor point(s) (see below) each with differing rotations and press the C-rotateit instead of the C-point button in the last step below)
:b4: i created a new layer and the moon by applying texture 28 to a smaller sphere which i drew beside the earth to have it’s center a z-depth 0, too. i hit "w" and dragged it to the left (only a small part of the gyro was still visible). i went to the "curve objects interpolates" section of the script’s commands and clicked the "3point" command, thus activating the load point_1 command, which i clicked, too. doing so, i saved the "attractor" for the curve i had in mind.
:b4: i dragged the moon back into view again and moved it in front by dragging the cursor downwards outside of the gyro several times. while doing so i kept an eye onto the z-settings in the transform-palettes info-panel and when i had reached -800 (for instance; as you probably know, negative values indicate, that pixols are getting in front) i hit "e" to be able to scale the moon. i enlarged it to what i thought to be double size (but as you can see i did not enlarge it sufficiently :(), hit "w", dragged it into the lower right corner and snapshot it. furthermore i hit the save-button in the "position marks" section of the script after making sure, that "selectMark1" was active. with this, i set the position from which the curve would start (Mark1).
:b4: i started dragging the cursor upwards out of the gyro until the z-depth in the info-panel read about 800 (positive to make the pixols sit "behind" the 0-level that earth was sitting on). i dragged the further away moon a bit upwards, hit "e" to be able to scale it and by dragging the cursor outside of the gyro i minimized the moon. i snapshot it and in the "position marks" section of the script hit the m+ button, so selectMark2 showed up... followed by a click on "save" to save the settings of the endpoint of the curve (Mark2).
:b3: end of setting the settings! :D
:b4: now for the fun: back into the "Curve Object Interpolates" section of the script’s commands: i activated C-moveit, C-sizeit, C-snapshot and C-point and hit "run interpolation"... ploinkploinkploink, here they come! if you are not satisfied with the number of moons (or whatever you are interpolating) make them disappear with command-z (after leaving transformation mode) and change the settings in the Ctime box. draw a new moon anywhere and try again by hitting "run interpolation". i think i did it at Ctime .18 but playing around with these settings is mucho fun so don’t miss it.
sorry for the long explanation, but i want to turn those on, who did not give the Digits Widgets a try! :D don’t be afraid: it’s not that complicated at all! i hope i did not make any mistakes, though!
