- 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.
- don't rotate (s,t) coordinates but rotate the patch instead !
- refactor osd/cpuEvalLimitKernels to share Far::PatchTables cubic spline
interpolation functions : this replaces tensor product formulation with
weight matrices, which does not really impact performance here, but would
have to be replaced when implementing regular gridding functions.
- fix OsdCpuEvalLimitController to not rotate coordinates and pass the rotation bitfields
- expose Far::PatchTables spline interpolation API (protected -> public)
- fix glEvalLimit tangent buffers (remove empty padding - see below)
- change policy for tangent buffers : the output buffer descriptor is
**NO LONGER APPLIED** to tangent output buffers. Tangent primvar data
buffers are no longer applying the offset and stride from the descriptor
(because it doesn't make sense to share it). If more flexiblity is
required, we will consider adding independent descriptors for the tangent
buffers. This change will impact existing code that generates tangents
with the EvalLimit controller.
fixes#370
- change topology refiner to check for edge sharpnesses when selecting faces for isolation
- add face-aggregator for edge tags to Vtr::Level
- fix logic in Far::PatchTablesFactory to correctly tag single-crease patches along infinitely sharp edges
note : this fix is a bit of a cludge - barfowl confirms that the vertex crease tags (VTags) are intended to
carry neighborhood information, which they currently do not. we will revisit this shortly and fix the tags,
which will allow us to simplify the traversal logic when isolating topology features.
fixes#369
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.
- VVarBoundaryInterpolation is now VtxBoundaryInterpolation
- enum prefix change from VVAR to VTX
- generel cleanup / doxyfication
- update of beta / release notes
- add error reporting callback to Vtr::Level::validateTopology
- switch printfs to callback
- add error code enums to Vtr::Level
- route Far::TopologyRefinerFactory::reportInvalidTopology through Vtr::Level callback
note:
- Vtr::Level::validateTopology needs to check creaase tag indices
- topology validation should be client-code driver in TopologyRefinerFactory (turned off in the code at the moment)
- 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
- change error codes from situational to general (fatal / coding / run-time...)
- pull error functions from Osd into Far
- add a templated topology validation reporting system to Far::TopologyRefinerFactory
- fix fallout on rest of code-base
- add python script to generate ReST from the C++ tutorial source files
- add css stylesheet for C++ syntax highlighting (based on my nedit settings)
- add functionality to CMake build to make it all happen
- add hyperlinks to tutorials.rst file
- 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
This empty cpp file is added to address some cmake dependency resolution issues
with XCode project-based build generation.
I may add some functionality to version.cpp in the future
Thanks stopiccot for investigating the issue and doing most of the leg-work.
fixes#356
Torii (and other planar topologies) are made entirely of regular b-spline patches and do not
generate sub-patches through adaptive isolation: we need to make sure that we construct
stencil tables with singular stencils for the coarse vertices instead of returning empty
tables (and crash in the limit stencils factory)
- added detection of sharp corners in generic scheme limit mask query
- tweaked Loop limit mask to simplify the regular case
- updated TopologyRefiner::Limit() methods to support all schemes
