- rename "Regular end cap" to "BSplineBasis end cap"
- revert templating and add EndCapType into PatchTablesFactory::Options.
- make EndCapFactories internal in PatchTablesFactory.
- move end cap stencils into PatchTables, keep them relative to the max level.
- add a utility StencilTablesFactory::AppendEndCapStencilTables to splice and factorize endcap stencil tables.
This change moves all gregory patch generation from Far::PatchTablesFactory
so that we can construct patch tables without stencil tables as well as client
can chose any end patch strategies (we have 3 options for now: legacy 2.x style
gregory patch, gregory basis patch and experimental regular patch approximation).
Also Far::EndCapGregoryBasisPatchFactory provides index mapping from patch index
to vtr face index, which can be used for single gregory patch evaluation on top
of refined points, without involving heavier stencil tables generation.
PatchTablesFactory fills 20 indices topology into patchtable, and use it for eval and draw.
note: currently screen-space adaptive tessellation of gregory basis patches is
broken and cracks appear around them.
- extend Far::PatchTables data structures & interfaces to store requisite
information for channels of face-varying bi-cubic patches
- implement gather function in Far::PatchTablesFactory to populate face-varying
channels with adaptive patches
- extend accessor interface in Vtr::Level
- propagate code fall-out throughout OpenSubdiv code base, examples & tutorials
- extend vtrViewer code to visualize tessellated bi-cubic face-varying patches
- renamed Sdc::Type to SchemeType and TypeTraits to SchemeTypeTraits
- renamed TYPE_ prefix to SCHEME_
- updated all usage within core library
- updated all usage in examples, tutorials, etc.
- move level of refinement / isolation into the Options structs
- fix splash damage in rest of the code
note 1: this is less than ideal, because most compilers accept the previous
call to these functions with an incorrect parameter list (ie. passing
the level instead of the struct issues no warnings and compiles...)
caveat emptor...
note 2: the level parameter names may not be final for adaptive modes
as we will likely want independent controls over crease vs.
extraordinary vertex isolation.
Const' declared instances of Vtr::Array do not protect the pointer held
privately by the class properly. In order to force the compiler to
protect this pointer, we removed all non-const accessors from Vtr::Array
(now renamed Vtr::ConstArray) and moved them to a child class (Vtr::Array),
which requires const_cast<> operators internally to allow access.
The change & renaming is then propagated to all internal dependencies.
- make sure we don't get conflicting enums (CODE_ERROR)
- fix template specialization for Far::TopologyRefinerFactory in regression/common/vtr_utils
- fix remaining error reporting code around osd
- split Far::PatchDescriptor into its own class (mirrors Far::PatchParam)
- hide PatchArray as a private internal structure
- add public accessors patterned after Far::TopologyRefiner (returning Vtr::Arrays)
- propagate new API to all dependent code
note: some direct table accessors have not been removed *yet* - see code for details
- adding support for StencilTables creation from a Gregory basis
- fix a bug in the prot-stencil allocator (slow memory pool was not being cleared properly)
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
