- added G.editMesh->derived pointer... idea is to use this
for mesh derived from editmesh instead of Mesh->derived (as the
derived mesh tends to vary depending on what it came from).
This part could be cleaner, also there may problems with it not
being invalidated correctly.
- And most importantly: In case people were beginning to worry all
these edits were just crazy zr stuff, the big point comes about:
Incremental subsurf calculation is now enabled. This gives massive
speed improvements when editing a large mesh.
For the eye-candy happy: try setting G.rt==52 before entering editmode
and the edges and vertices (in optimal mode) will switch to displaying
visually the age since a region has last been calculated. Lots of
fun!
overrated. Turns out there was a bug in recalc code where
in editmode mesh was getting reevaluated all the time (because
ob->disp doesn't get built in editmode). This should fix.
- Fix some normal calculation/backwards face drawing
to determine if element should be drawn and to set draw options),
which meant some could be combined - eases implementation of new
DerivedMesh types and keeps more app specific logic out of DerivedMesh
implementations.
- removed DL_MESH displist type!!!! Now store a DerivedMesh directly.
- May still be some issues left having to do with releasing this
at the right time (old code just splashed free_displist all
over the place).
- switched drawmesh.c to use new functions
- WHEE! This is last such function that has to be written for the time
being, and also effectively marks the end of DL_MESH! DispListMesh still
hangs around as a kind of interchange format but should also die once
DerivedMesh provides more intimate mesh access.
DL_MESH (the displist type for DispListMesh) is still used to hold
the DispListMesh, but that will die as soon as new subsurf switches to
using a bonafide DerivedMesh implementation. There is also one silly
usage for the decimator that is easy to kill.
- Oh, and I also made potatoe mode draw mesh vertex colors - seemed to
be more uniform behavior.
- cancelled previous commit to add RE_findTFAce, instead just added
a MemArena to render struct... free'd at end of render, can be used
to store other data as well
- switch rendering to using DerivedMesh API... this is slightly more
inefficient now because it is doing some unnecessary copying. Can
be fixed by defining a DerivedMesh function to convert the object
into a render object (on todo list)
implementations (slightly redundant, could implement draw in terms
of first... can be cleaned later)
- switch to use of new APIs... all uses of EditVert->ssco are now
clean (read: ready to die as soon as a proper DerivedMesh implementation
is swapped in with ccgsubsurf)
implementations
- updated drawobject selection code to use DerivedMesh (last DispListMesh
usage in drawobject.c that needs to be replaced! Woot!)
- interface could still be a lot cleaner, mostly calculating indices for
the various things to pass to selection color routine is hacky.
this is to ease migration.
- updated particles and STL converter to use DerivedMesh interface. This
is a bit wasteful at the moment, but these are not key performance areas.
Can update once DerivedMesh has accessors for faces and face data.
