Standard infinity curve.
step 1 of 18
step 2 of 18
Standard sphere, front polygons selected ready to be cut away.
step 3 of 18
Front polygons from step 2 moved in to a new layer to be used as the glass.
step 4 of 18
Add a new poly to front of the sphere for the face.
step 5 of 18
Standard cylinder was created and beveled back, then placed inside the sphere where extra edges where added using the edge slice tool ready to add new polygons for the SDS surface.
step 6 of 18
Vertices are selected in a clock wise order for the new polygons.
step 7 of 18
All the polygons added.
step 8 of 18
S.D.S surface
step 9 of 18
S.D.S surface need a little more tweaking with edge slices as there was still some pinching.
step 10 of 18
Chain links was made with a single cylinder which was bent over 180 degrees then duplicated and bridged together. Then completed chain was bent round the circumference of the sphere.
step 11 of 18
Start of the gears made from the top of a cylinder.1 segment anything from 80 to 102+ sides. Quick tip all ways remove the front and back polygons when doing this. will save you a lot of mesh clean up……. especially if it will be a S.D.S surface.
step 12 of 18
Another gear front and back polygons are sliced and then removed and then bridged.
step 13 of 18
Few more hours later and more gears.
step 14 of 18
Cover plates for the gears first try. Many of the same principals as previous steps.
step 15 of 18
Final S.D.S surface many hours of work 100’s re-works and that’s an understatement.
step 16 of 18
Clay scene to check lighting is correct. Always do this before any textures or materials are added. Light for this was one single low level photometric light and a mirror ball for the window reflection. Very experimental not sure if it worked or not…
step 17 of 18
Render preview
step 18 of 18
This step is just to show that the chain is actually touching the sphere. Although in the final render is looks like it is not. Will have to put this anomaly down to camera angle and the bouncing of light.
