How to "clean" the transforms of a gdp

[Guest xionmark]

Hello,

How do you "clean" or reset a gdp (GEO_Detail *gdp) of any previous transformations from calling gdp->transform() ?

I can't find anything in the docs and I've tried something like:

   UT_Matrix4 xform(1.0);
   xform.identity();
   gdp->transform(xform);

But no luck, the transforms continue to accumulate every time I transform the gdp to a new location.

Thanks!

In general, you can't because when you're transforming the geometry, you are modifying the point positions directly. So you have to decide what you want the "rest" position to be and transform it again to that.

Ah ha! That's it!

Mucho gracias Edward!
