Changes for 1.9.17

DATAKIT, Express, IGES, JT, openNURBS, Parasolid, SAT, SolidWorks, STEP, STL, VDAFS: Update version numbers for release. 2015-02-01
Patch shared_ptr usage for latest Apple compilers. 2015-01-26
Latest LLVM apparently doesn't like tr1/memory. 2015-01-23
DATAKIT, openNURBS: Change _MSC_VAR typo to proper _MSC_VER. 2015-01-23
Add support for v25 and v26 schemas. 2015-01-18
DATAKIT: Merge changes from latest utiltslib.cpp. 2015-01-12
STEP: Silence SHAPE_DIMENSION_REPRESENTATION error. Exact same effect (it is ignored) but now it is ignored quietly. 2015-01-08
STEP: Port last AP242 fix to STEP. 2015-01-08
Express: Skip SHAPE_FEATURE_DEFINITION shape reps. This appears to be some sort of AP242 annotation, marking information about faces which are already included in other geometry constructions. 2015-01-07
STEP: Add shape_dimension_representation to STEP schema. 2015-01-07
STEP: Better message when we cannot process an entity. 2015-01-07
Express: Slightly more informative errors. 2015-01-07
Express: Explicitly ignore SHAPE_DIMENSION_REPRESENTATION. This cuts out a bunch of annoying messages from the translator. If we ever actually support doing something with shape dimensions, this would presumably be removed. 2015-01-07
Express: Better problem feedback. 2015-01-07
Switch $*DISTRO to $*KERNEL.name. 2014-12-22
STEP: Improve to-do comment. 2014-12-17
Express: Get Express working with new HwFilename. This adds a C-interface which takes wchar_t pointers for the path arguments. It also adds tests that utf8 filenames work with the C char * interface. 2014-12-09
openNURBS: Make linked files work. 2014-12-09
openNURBS: Add HwFilename argument to high level ON import. This is needed in case we need to construct a full path from a relative path in a link. 2014-12-09
Add HwFilename::RemoveLeadingDotSlash. This removes leading "./" or ".\" from filenames. 2014-12-09
Pull in the HwFilename changes needed for on-linked-files. 2014-12-09
Add InPlaceUtf16ToUtf32IfNeeded. This is needed because openNURBS (and presumably others) use utf16 in wchar_t / wstring structures even on platforms where wchar_t is 4 (or 8?) bytes and should properly be utf32. This function does an in-place conversion from utf16 to utf32 if sizeof(wchar_t) > 2. 2014-12-09
VDAFS: Don't send non-ASCII characters to islower. 2014-12-08
DATAKIT: DATAKIT / HwFilename update take two. 2014-12-08
DATAKIT: Bring DATAKIT up to new HwFilename. 2014-12-08
SolidWorks: Try to make SW work with current HwFilename. 2014-12-08
JT: Rearrange comparison for portability. We were checking sizeof(wchar_t) == 4, but it might also be 8 on evil platforms. So switch to checking for the sizeof(wchar_t) == 2 case. 2014-12-07
JT: Rework Unicode support a tad. 2014-12-07
IGES, VDAFS: TestUnicodeFilenameExport => utf-8/wchar_t tests. Instead of choosing to do utf-8/wchar_t based on the HW_ALLOW_UNICODE_FILENAMES flag, always do both. 2014-12-06
Remove unused member variables from HwFilename. 2014-12-06
SAT, STEP: Kill operator + (char const *, HwFilename const &) It was only used two places, and those are clearer now without it. 2014-12-06
IGES, JT, openNURBS, SAT, STEP, VDAFS: Complete overhaul of HwFilename. This makes it clear that the HwFilename either stores a utf8 string or a wstring, rather than pretending the former is ASCII and the later Unicode. Also makes conversions between the two more robust, and wstring now always works rather than only working when HW_ALLOW_UNICODE_FILENAMEs is set. 2014-12-06
Add HwStdString.clear. 2014-12-06
openNURBS: WIP Check-in of ON linked instance handling. 2014-12-05
Express, IGES, SAT, STEP, SolidWorks, VDAFS, JT, openNURBS, Parasolid, DATAKIT: STACKS -> HW_STACKS, RMATRIX -> HW_RMATRIX. 2014-12-03
When looking for surface color, consider internal. 2014-11-28
Add GetContainedSurface. This makes it easy to walk down all the contained surfaces until you find what you're looking for. 2014-11-28
Express: Port Baugruppe fix to Express. 2014-11-25
STEP: Further refinement of the desperation case. 2014-11-24
STEP: Try inverting the "nothing makes sense" logic. 2014-11-23
Colorless trimmed surfaces get surface color. If available. 2014-11-20
Add iges_assembly.cpp, etc. to the distributions. 2014-11-20
If no face color, use surface color instead. 2014-11-20
Lose HwNlibOperators.h ref from HwNlibAttribute.h. 2014-11-07
Quick HwUtf32ToUtf16 which will work for now. 2014-11-05
STEP: Don't allow illegal strings to shut down export. 2014-11-05
Templateize HwAssembly::AddObject. 2014-10-23
Try to fix some MSVC++ warnings. 2014-10-21
DATAKIT, Express, IGES, JT, openNURBS, Parasolid, SAT, SolidWorks, STEP, STL, VDAFS: Update version numbers for next development cycle. 2014-10-20

Changes for 1.9.16

STL: Add STL to the version number system. 2014-10-18
DATAKIT, Express, IGES, JT, openNURBS, Parasolid, SAT, SolidWorks, STEP, VDAFS: Update version numbers for release. 2014-10-18
JT: Streamline ReadMbString. 2014-10-15
JT: Use utf-8 instead of STEP string format. 2014-10-14
STL: Always export STL in little endian. 2014-10-14
Allow STEP to export and import levels using the layer mechanism. This writes levels as layers named "Level N", and reads layers named like that as levels. 2014-10-14
STL: Detect endianness for binary STL import. 2014-10-14
DATAKIT: Skip degenerate coedges in loops. I think these may be vertex coedges?. 2014-10-09
openNURBS: Correctly count extrusion surfaces as B-reps. 2014-10-02
openNURBS: Plug memory leak in extrusion support. 2014-10-02
openNURBS: Convert standalone extrusion surfaces to B-reps. 2014-10-01
openNURBS: Count surfaces as surfaces rather than curves. 2014-10-01
DATAKIT: V2014.4 changes. 2014-10-01

Parasolid: Trap weird SP curves and make them more sensible.

         This looks for cases where an SP curve is an entire loop by itself,
        but the UV curve in it is an isocurve which is NOT closed in 3D space.
        In that case we substitute a similar isocurve which does go across the
        (presumably closed) surface's entire parameter space. 2014-09-29

Add HwNlibCurveOnSurface::AssumeNewCurve. 2014-09-29

Parasolid: Revert the logic unless negative radius torus.

         Previously we had switched the orientation logic on all degenerate
        surfaces. This reverts to the previous behavior unless the major
        radius is negative. 2014-09-20

Parasolid: Remove the prohibition on negative radii in torus. 2014-09-20
Express: Only dump curve type if it is non-null. 2014-09-15
STL: Fix capitalization of include file name. 2014-09-12

IGES: Tweak IGES import settings for Gridgen.

         If Gridgen is detected, p_face_orientation_is_surface_only is set to
        false. 2014-09-12

Add primitive basic STL translator feature to master. 2014-09-08

STL: Switch STL export to use HwLowLevelBinaryWriter.

         This abstracts things more, and should make it easier to deal with
        32-bit / 64-bit and endian issues. 2014-09-08

Straightforward class HwLowLevelBinaryWriter. 2014-09-08
STL: HwNlibStlWriter to use HwLowLevelBinaryFileOutput. 2014-09-07
Add HwLowLevelBinaryFileOutput class. 2014-09-07
Add HwLowLevelBinaryOutput virtual class. 2014-09-07
IGES, STEP: Port classic Pro/E hacks to CREO PARAMETRIC. 2014-09-06
Add missing HW_CORE_EXPORT for Windows. 2014-09-05
Don't trigger an assertion in GetSamplePoints if one of the curves is incredibly short. (If we don't do that here, then the short curve will be properly deleted later.). 2014-09-03
Express: Tweak things to make different APs work again. 2014-08-30
Express: Add AP203 E2 to the infrastructure. 2014-08-30
DATAKIT, Express, IGES, JT, openNURBS, Parasolid, SAT, SolidWorks, STEP, VDAFS: Update version numbers for next development cycle. 2014-08-27

Changes for 1.9.15

DATAKIT, Express, IGES, JT, openNURBS, Parasolid, SAT, SolidWorks, STEP, VDAFS: Update version numbers for release. 2014-06-12
Fix HwNMTLibObjectWrapper point attributes. I had forgotten to add this. 2014-07-24
Add examples dealing with points. This helps explain HwWrapObjectWithIwAttributes in a practical way. 2014-07-24
STEP, Express: This adds support for STEP files which reference external STEP files using the DOCUMENT_FILE entity. 2014-07-23
Fix glaring hole in SurveyCounts need_expansion. 2014-07-21
Adds support for DATAKIT V2014.3. 2014-07-17
STEP, Express: Fix the parameterization of circles, ellipses, cones, cylinders, spheres, and toruses. 2014-07-16
Catch more cases of small loop on big sphere. 2014-07-15
Add GetBaseSurfaceSameNormal. 2014-07-15
Express: Clean up trimmed curve code a tiny bit. 2014-07-08
Express: Allow broken coordinate systems for spheres. Since all we absolutely need from it is the center... 2014-07-01
Express: Wire up CLOSED_SHELL processing. 2014-06-30
Express: Properly pass HwExpressFlags in to assembler. 2014-06-30
STEP: Check for a valid entity. This prevents a fatal assertion failure. 2014-06-30
Express: When import is going badly, grasp at a unit. Ported over from STEP translator. 2014-06-29
Express: Don't abort counting if a shell object errors out. Also, if it does, don't count it as a B-rep. 2014-06-29
Express: Don't just assume the FACE_BOUND is good. 2014-06-29
Express: Only look at MAPPED_ITEMs and not their subtypes. There's weird stuff going on with the intersection of GetEntitiesT and ExpExternalMappingEntity, so for now just look at explicit MAPPED_ITEMs. 2014-06-29
CopyWithChange takes a tolerance now. Which allows PullOutObjectArray to give you the actual tolerance. 2014-06-29
Express: Filter out duplicate coordinate systems caused by looking at both CONSTRUCTIVE_GEOMETRY_REPRESENTATIONs and SHAPE_REPRESENTATIONs. Incidentally will also filter out things if they are used more than once by the same SHAPE_REPRESENTATION. Dunno if the later behavior is correct or not, I'm not seeing any downsides at the moment. 2014-06-29
Express: Do a better job counting geometric sets. 2014-06-28
Express: Hook up constructive geometry representation. This may open up issues where a coordinate system is loaded more than once. Next step is to try to find a file where that would happen... 2014-06-28
openNURBS: Fix illegal memory access. This was an issue that somehow snuck in with the latest openNURBS changes. 2014-06-25
openNURBS: Support for face colors in standalone faces. 2014-06-22
openNURBS: Move HwNoMaterials to a header. Needed this for face material support (or lack there-of). 2014-06-22
openNURBS: Fix material table. This makes face color export work again, for the first time in years. 2014-06-19
openNURBS: Work around missing face loop info. When we only have one loop on a face, assume it is the outer loop. Either it really is the outer loop, in which case the assumption is okay, or it is a loop on a closed analytic and openNURBS won't be able to handle it correctly anyway. 2014-06-19
openNURBS: Add material name based on color info. 2014-06-19
openNURBS: Create UUIDs for materials. 2014-06-19
openNURBS: Write version 5 files by default. 2014-06-19
openNURBS: Test for correct UUID creation. Okay, this isn't a sophisticated test, but it does check that the openNURBS UUID creation function is doing something. By default (in the current source) UUID creation is disabled on Linux. Without it the export will be very confused. I've patched it in my development source to use uuid-dev on Linux, and that seems to work. 2014-06-19
Add HW_VERSION_NUMBER to the version management. New bump_version.pl6 script for bumping. 2014-06-18
openNURBS: Rework how colors are written. 2014-06-18
openNURBS: Attempt to handle recent OpenNURBS properly. Two things here. First, most of the #ifs have been rewritten to use defined(HW_OLD_OPENNURBS). This means you're compiling with OpenNURBS 2.0 or 3.0. This has not been tested, and is mostly to keep the old code around in case someone needs it. The second thing is an attempt to implement face colors properly for more recent openNURBS. This commit includes code for importing them, but it is mostly untested as well, since we do not have any convenient files to test it on. 2014-06-17
openNURBS: Refactor to get GetMaterialIndex. 2014-06-13
STEP: Add step_treat_manifold_surface_shape_representation_as_object option, hook it up so that it works. 2014-06-13
STEP: Basic code for processing MSSR as single entity. This allows handling manifold surface shape representation as a single entity. The logic to control turning this on and off is not yet included. 2014-06-13
STEP: More refactoring of shell_based_surface_model. 2014-06-13
STEP: Refactor ProcessShellBasedSurfaceModelInternal. 2014-06-13

Rip out the edge curve tweaking bits of HwTSLibTrimmingTools::CleanGeneratedEdgeCurves. They might (in theory) be useful, but in practice they were doing a half-assed, incomplete, and possibly incorrect job, and turning them off makes no apparent difference to the performance of our test suite. 2013-04-23.
Don't skip the first knot when checking to see if the knot you want to add is already present in the curve. 2013-04-23.
