gear teeth profiles are very customizable

you'll even be able to make daisies, or stars or hexagonal, octogonal nuts/bolt heads

-----

note that they are crowns, in the image below, one is mounted on a mcjFlyWheel and another one is mounted on a mcjPlateOnePipe

fig3 - redesigning the teeth for edge sharpening morphs

this is not a donut

this is a gear

32 teeth

16 rings of 16 vertices per tooth

---

but there will probably be more polygonally economical versions of the supermorphable gears

mCasual · November 2014

see, it will even be able to be a crown gear ( teeth above the torus ) or a ring gears ( teeth inside the torus )

this is just a demonstration, in fact this morph was created using mcjElevate and a displacement map

mCasual · November 2014

well today is Sunday so, chances are the super gears will be ready in the next 8 hours time slot :)

this date also coincides with Hivewire's Dawn SR2 arrival

( which by the way, like any vertex based figures could be made to work moderately well in old versions of Poser and Daz, given a little effort )

=============

Fig 2 - Same donut with sharpen morphs

Fig3 - it's basically a higher resolution de-evoluted version of the mcjPlateOneHole
and instead of 4 corners, we want 32 teeth

Fig 4 - Costom teeth shapes ( 16-steps curves )

fig 5 getting there ...

MilosGulan · November 2014

Very interesting. I am curious about Dawn figure too :) Thanks for info.

mCasual · November 2014

sinewave teeth

note that the "sharpen" morphs are not there yet

Figure 2 : Tada ! the sharp-Edge morphs

mCasual · November 2014

not sure yet how the presets will be included/applied

that's the preset for the most common type of gear

------

the "stretch" visual effects are a bit annoying ... but come to think of it, maybe ..... turning the material's "smoothing off" ... yeah it works
but it's a trick ... guess i'll add a few vertex rings

=====

figure 3 there you go, i went for this solution. each one of the 16 rings of facets has its own material
so but turning "smoothing" off on the top, bottom and hole-walls, we get rid of "stretch marks"

mCasual · November 2014

neato !

ring gears and crown gears !

mCasual · November 2014

the shape of all 32 teeth will be fine-tunable using 16 "radius" morphs and 16 "rotate" morphs

figure 5 - problem with sharpness
possibly due to the order in which the radius and sharp morphs are applied

mCasual · November 2014

here you can see my problem to solve

the small gear edge sharpness morph is all messed up by the teeeth-morph

but the large 32 teeth gear doesnt have that problem

maybe .... the Poser scale is causing a loss of precision?

hmm, i know, i'll compare teeth number 0's deltas in both props

( pretty sure i did normalize my "push" vectors" so they should not be influenced by the initial vertex position )

.
.
.
Found it !!! i think .... the teeth morph maker was working on the assumption that there were 32 teeth, not 8
.
.
.
yep that was it , my script was probably piling up morph deltas 4 times

.
.

--------

there will probably be 5 x 2 x 3 ... that's 30 props

8, 12, 16, 24, 32 teeth

though the 32-teeth prop will be able to morph into a 64 and 128 teeth gear

4, 8 or 16 "slices" per tooth

8 or 16 segment per "slice"

so a minimal resolution 32-teeth gear will be 8 x 4 x 32 = 1024 faces
a full-resolution 32-teeth gear will be 16 x 16 x 32 = 8192 faces

mCasual · November 2014

well i'm wrote most of the script to generate the 30 props and their hundreds of morph channels

Figure 1 and 2 the 256-faced morphing donut - which will "carry" a slider to turn it into an 8-teeth gears

but since those props are very versatile, i dialed-in an octagon nut !

FIG 3

fig 4 the 6 resolutions for the 8-sided or 8-toothed props

mCasual · November 2014

since i automatized the production of the morphing props,
and since it can be used for other things than gears
i will include 3, 4, 5, 6 teeth props ( each in 5 resolutions )
for a grand total of 54 props

in the very distant future i may make the same without the center hole

Fig 2 note that if you google a bit you can find online gear design apps
http://hessmer.org/gears/InvoluteSpurGearBuilder.html

and with some photoshopping you could create transparency and/or displacement maps, and build fake 1-polygon gears

fig 3 maximum teeth will probably be 128, using the 32-teeth torus

fig 4 fake gears using an opacity and displacement map ( negative image of figure 3 )

fig 5 - half way done adjusting the default teeth for the 3, 4, 5, 6, 8, 12, 16, 24, 32 teeth gears

Miss B · November 2014

WOW, these look wonderful. I'm already thinking how I could use them. :coolsmile:

MilosGulan · November 2014

Looking good :) will try to use them too.

mCasual · November 2014

each prop will have a master slider to turn it into a

- spur gear
- top face gear ( crown gear )
- bottom face gear
- Internal ring gear

when you load the prop, it will be a spur gear, with moderately sharp edges, and an appropriate hole size

i mean if the Timbits were larger than the donuts and it wouldn't make sense would it?

( the base prop is a smooth torus with no teeth )

-----
figure 2, the result of applying the spur-gear's teeth profile to the crown gears and the ring gears .... i'll probably improve on this

ThatGuy · November 2014

these look really cool. Can't wait for you to make them available!

high hopes for a Thursday release

i just have to see if the poser-prop exporter part of my script is ready to export the 54 , now, fully functional props

---

figure 2, had to change the teeth growing master controls, so the teeth grow outward, though i may retain the teeth carving control

stronghands · November 2014

Wow. Awesome work on these. Excellent tooth profile too.

today or tomorrow i'll post the .obj grouping tool
it was hardcoded in a way only i could use it,
but now it should work for anyone
provided you have windows/msdos
and you can write and run a batch file like this:

though i will publish the cpp source code so someone else could compile it and run it in Mac or Linux

the file named GROUP_mcjSLWomanJumper.bat
located in the same folder as mcjObjGroupByProximity .exe


SET MCJA="C:\\\\Program Files (x86)\\\\DAZ\\\\Studio\\\\content\\\\Runtime\\\\libraries\\\\Character\\\\SL Avatar\\\\SL_Female.obj"
SET MCJB="C:\\\\Program Files (x86)\\\\DAZ\\\\Studio\\\\content\\\\Runtime\\\\libraries\\\\Character\\\\SL Avatar\\\\old_mcjSLWomanJumper.obj"
SET MCJC="C:\\\\Program Files (x86)\\\\DAZ\\\\Studio\\\\content\\\\Runtime\\\\libraries\\\\Character\\\\SL Avatar\\\\mcjSLWomanJumper.obj"
mcjObjGroupByProximity %MCJA% %MCJB% %MCJC%
pause

the free SecondLife avatar is a poser compatible figure, it has the proper groups

SL_Female.obj is the "reference" figure, or donor

old_mcjSLWomanJumper.obj is the non-grouped clothing item i modeled

mcjSLWomanJumper.obj is the resulting clothing item with all its 6000 faces grouped by the proximity to the facets in the reference figure
