Base model and morphing with targets

[michael_polak]

Hi all,
I see there is a base.obj file in the data/3dobjs folder but this object does not match the one I get if I just load the program and export the body as an .OBJ file. Can someone explain why is this so?
Thanks!

The starting point does have quite a few morphs applied it's explained a bit more fully somewhere here on the forum as well a search should find it as your question has been asked before.

Enjoy the Choice

The start model has 33% caucasian, 33% african and 33% asian applied. This makes it look different than base.obj.

Thanks for the info Joel.

Thanks for the info Joel.

One more thing... can someone point me to a resource that describes how the morphing works? I think I understand it but I'd like to see some docs to make sure. If the base model is female with the 33% of each african, asian, and caucasian targets (asian-female-young.target for example) then when a separate target is applied it is simply the weighting [0,1] multiplied by the delta vectors for each point listed in the target added to the base model (that already has those other 3 targets applied). If that is not the case, please explain or point to the docs and I'll RTFM.

Thanks!

That's the video I watched to get the understanding that I currently have about how targets work. If they are not any more complicated then what I described, that is great.

This is basically it. Nothing more magical is happening outside this.

If two targets influence the same vertex in the same direction, the vertex will move the combined distance. If the targets move the vertex in opposite directions, the movement will be canceled out.

To see what targets have been applied, you can use the scripting plugin and run printDetailStack(). On a default model, it will give this output:

Code: Select all

So as you can see you have both male and female versions of the ethnicity and average weight targets applied from start. Basically in combination 33% of each ethnicity and 100% of average weight.

That logging is useful. Thanks for the listing and the explanation.
