Zsphere Philosophy: complex meshes with inner components.
Dear Zbrush experts and forumers.
All of you, presently having gained more experience with Zballs, may give me a few recommendations as to the difficulties I encounter when building complex meshes with other meshes introduced into the outer.
I used to compose anatomical structures. The plastic flow can be achieved amazingly punctual by the Zspheres all right. But, to show the inner anatomy of the objects in question, I manipulate spheres inside the primary ones, as though filling the cavity. Thus the result comprises both the skin and the inner contents. The whole formation can be visualized either within Zbrush, if you mirror the 3D mesh within the Tool palette or you might prefer, like me, to Flip normals.
Zbrush 1.5 can beautifully display by the Dot mode, which it better, I feel, to be called āWireFrameā mode. By that you can see the whole object as if transparent.
Other programs, possessing Dots mode and Wireframe mode or Transparent mode, help me when I wish to check up the resulting mesh without displacing the Zballs construction.
Of these I enjoy 3D exploration (growing up to become Deep Exploration) and Poser.
Regretfully Zbrush 2 lacks the dots mode possibility (dots, not mesh lines).
Normally, Zspheres are good to branch the mesh out. The next skinning fills the gaps to conform. We may build arms, elevations and crevices in the surface. The skin goes from one sphere to another in a regular even way. There are instruments to affect spheres prior to the mesh and then, afterwards, we may deform the mesh itself. It is great: the Zsphere as a unit building element.
Now let me speak about the problem. I have already sent you letters regarding the innter mesh.
In difference to other 3D artists, I apply the plunging Zspheres not only to compose excavations but the canals and cavities.
For instance have a look at the image of the uterus I built mainly in Zbrush: the cavity and the cervical canal also shown (A).
To perform such, one should insert the zsphere branch inside the outer branch.
Only, if the zphere goes too deep inside the outer one, the opening closes and the resulting mesh may become like shown in (B).
That is all right in terms of anatomy at a glance. But it happens so, that, in difference to the outer- from outer linkage (branch) the mesh makes a crossroad! I.e. the plunging Zsphere sends the mesh to the other side of the canal Ā©. This drawback can prevent to normally deform this part of the mesh afterwards. C shows beautifully the bug when one zsphere enters another.
I have tried a lotta means, all plugging of yours too, with intent to rotate the mesh, but all in vain! It would be great if one could control the behavior of the Zsphere in this regard!
I definitely hope the next addition of Zbrush might cope with this worry or obviate it with the new rig. In the meantime you may find some resolution earlier.
Also, it woud be great if the Zspheres could be able to connect entirely, in a way of a circle, suggested, artificially, in (D). The whole structure may then be planned in Zballs!
:rolleyes:
