Methods D0, D1, D2, D3, DN of the class GeomEvaluator_OffsetSurface are extended by additional tweak to compensate failure of normal calculation in degenerated points on triangular surfaces.
If the point where normal has failed to calculate is located on parametric boundary of the base surface, one more attempt is made with the point shifted towards interior by Precision::PConfusion().
STL Reader and Writer tools have been refactored to improve performance and usability:
- Basic reading of STL file is separated to abstract class RWStl_Reader which is not bound to particular data structures; the target data model can be bound via inheritance.
- RWStl package uses class Poly_Triangulation to represent triangular mesh.
- Obsolete data structures and tools (packages StlMesh and StlTransfer) are removed.
Image_VideoRecorder - added new class for video recording using FFmpeg framework.
Draw Harness command vanimation has been extended with new options for video recording.
New optional dependency has been introduced - CSF_FFmpeg.
The following implementation has been made:
- CMake procedure is extended to compile Qt tools. This is optional and is handled by USE_QT_TOOLS option(OFF by default)
- It is possible to build Qt tools using Qt5 or Qt4, it is settled with USE_QT4 option.
- Sample of DFBrowser tool is available in samples/tools/TInspectorEXE. It is build with tools, executable is placed in binaries. To start the sample, use dfbrowser.bat command.
- DFBrowser tool may be started from DRAW
Eliminated GCC warning -Wsign-compare introduced by patch for #0028786.
Eliminated (false) GCC warning -Wuninitialized introduced by patch for #0027117.
Suppressed GCC warning "-Wunused-but-set-variable" with OCCT_DEBUG defined
AIS_LengthDimension interface was extended to allow setting a custom dimension direction.
The value of dimension in this case is equal to projection of the distance between dimension attributes(points) to this direction.
vlengthparam command is implemented to set custom length direction in DRAW.

StdPrs_ToolTriangulatedShape::ComputeNormals() now calls Poly::ComputeNormals() for triangulation-only surfaces.
Poly::ComputeNormals() now averages normal considering triangle size.
Template for LaTeX header used in generation of PDF manuals is corrected to avoid multiple errors during processing by LaTeX (which can eventually lead to LaTeX aborting if their count exceeds 100).
Names of log files generated by gendoc command are made dependent on target format and (for PDF output) document name.
Formatting bug is fixed in DRAW User Guide
Graphic3d_AspectFillArea3d now stores array of textures.
Graphic3d_TextureParams stores texture unit for mapping texture.
OpenGl_Context::BindTextures() - context now manages the set of active textures.
Related code has been removed from OpenGl_Workspace.
OpenGl_Sampler has been extended to hold texture parameters structure.
OpenGl_Texture now holds OpenGl_Sampler instance as class field.
OpenGl_Texture inherits new class OpenGl_NamedResource and holds
texture identifier used for sharing resource in OpenGl_Context.
OpenGl_RaytraceGeometry now creates bindless textures taking
Sampler object directly from OpenGl_Texture.
OpenGl_Context::BindTextures() automatically recreates immutable
Sampler Object on texture parameters change.
Declared new structure OpenGl_ArbSamplerObject for platform-neutral
usage of related functionality.
Related functions are now loaded within OpenGL ES 3.0+.
Declarations.glsl - occActiveSampler has been renamed to occSampler0
with aliases occSamplerBaseColor (main) and occActiveSampler (for compatibility).
Additional texture samplers should be declared explicitly
within specific GLSL program as occSampler1, occSampler2, etc.
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.
vshaderprog now accepts Shader source code as parameter.
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.
OpenGl_Context::SetTextureMatrix() - fixed inconsistent handling
of texture cooridnates translation vector.
vtexture command has been extended to handle new arguments:
* -trsfTrans, -trsfScale, -trsfAngle defining transformation matrix
* -setFilter, -setAnisoFilter to setup texture filtering
Modify mfc and qt samples for supporting VS 2017.
Create general vcxproj files for all mfc samples.
Correction msvc.bat and msvc_D3D.bat in CSharp sample
Added support of Visual Studio 2017 (15) in CMake build procedure.
CMake 3.7.2 or above is required to generate projects for VS 2017.
Since version of compiler and toolset remained at 14 (now they are 14.1), and they use the same run-time, the same third-party products as for VS 2015 (14) can be used.
Also the name of the folder for installation of OCCT binaries in OCCT-standard layout (default on Windows) remains "vc14".
Support of Visual Studio 2017 is added in genproj generator and relevant environment, with format specifier "vc141".
The syntax of the genproj command is revised:
- UWP is considered as separate platform ("uwp" alternative to "wnt"), not part of IDE specification
- Option "IDE" is renamed to "Format"
- Obsolete name of local variable "aWokStation" is replaced by equivalent "theFormat"
In environment scripts, additional variables are defined (derived from VCVER, see adm/vcver.bat):
- VCLIB defines name of the subdirectory specific to VS version; it is the same as VCVER except that for VCVER=vc141 VCLIB=vc14 and for VCVER=141-uwp VCLIB=vc14-uwp
- VCFMT is VCVER without optional suffix "-uwp"
- VCPROP is "NativeDesktop" for normal builds or "Universal" for UWP builds
Command genconf is amended to:
- Detect presence of VS 2017 (separately for desktop and UWP)
- Use only two first digits after "vc" in format specification for search of third-party libs
- Have more space in user interface for VS specification
All supported variants of VCVER variable are documented in dev guides / buiding / msvc
V3d_View::SetComputedMode() - removed implicit View update.
Graphic3d_CView::SetComputedMode(), ::ReCompute() - fixed
uninitialized bounding box of Computed structure.
PrsMgr_Presentation::Compute() - fixed computation of Computed structure
with transformation within Connected presentation.
StdPrs_HLRPolyShape::Add() now creates Graphic3d_ArrayOfSegments instead of
inefficient Graphic3d_ArrayOfPolylines with boundaries at every segment.
Fixed error in test case bugs/vis/bug24388_1.
DeviceLost flag has been moved from Graphic3d_GraphicDriver to Graphic3d_StructureManager,
so that all Viewers sharing the same Driver instance are properly invalidated.
Fixed clearing of objects by vclear command in case of multiple Viewers.
