- changed ptex layout data types in shaders to match srv format
- changed ptex srv type to unorm format for uchar data
- fixed hlsl compiler warning: initialized edgeDistance of OutputVertex struct in domain shader even if we are not in wireframe mode
- added directx debug device and enabled automatic break points to easily spot dx errors
- all Factory<MESH> methods to specialize now return bool
- added topology validation of base level as indicated by option
- added populateBaseLevel() back to simplify premature failure
- 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.
- 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.
- fixed naming consistency of protected methods used by Factory
- removed other unused and/or redundant protected methods
- update Far Factories to reflect changes to Refiner methods
- updated usage in tutorials and regression
- changed template parameter to runtime method parameter
- added traits as static methods of all schemes
- constructed internal table of traits from all schemes
- 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.
