Introduced NCollection_AliasedArray collection defining a general byte array
to be aliased as array of elements of mutable type.
Poly_ArrayOfNodes specializes this interface for collecting 2d/3d points with single/double precision.
Poly_Triangulation relies on this new class for definition of 3D nodes and UV coordinates
using gp_Pnt and gp_Pnt2d by default as before.
RWGltf_CafReader now fills in triangulation using single precision by default (as stored in the file).
OpenGl_LayerList::renderLayer() - fixed usage of wrong camera while rendering shadowmap,
and apply Z-Layer origin shift to shadowmap matrix while applying shadow.
1) Remove unnecessary includes of "Standard_OStream.hxx" file and add it only into files where it is really used.
2) Create the base interface for a file stream provider OSD_FileSystem and its inheritor OSD_CachedFileSystem that keeping last stream to be reused for opening a stream with the same URL.
3) Use OSD_CachedFileSystem object instead of RWGltf_GltfSharedIStream during Gltf reading.
Added new class AIS_LightSource representing a light source presentation.
Graphic3d_TMF_CameraPers - added new mode to Graphic3d_TransformPers
defining 3D point relative to camera Eye position
- Upgraded files using new version of WinFlexBison
- Removed global variables within StepFile_Read.cxx
- Upgraded error message during bison analyzing ( added a expected expression information )
- Used 'Interface_ParamType' as argument type for the StepFile_ReadData::Argument
for a compatibility with the StepData/StepData_StepReaderData
- Added handling parse errors and transferring it to the StepData_StepReaderData
- Now parsing and referencing errors save in the check and non output by default
- Step_file's and Step_Data's output info prints according by trace level of printer
- Removed useless location.hxx
- Removed TraceLevel for the StepFile_Reader ( now it useless,
it is 0 by default and newer and nowhere change )
- Translate error message into English within StepData_StepReaderData
- Replace "Error" word in the output messages
Added image formats Image_Format_RGF_half/Image_Format_RGBAF_half
with manual conversion between 32-bit float and 16-bit half-float values.
PBR LUT table is now converted into GL_HALF_FLOAT_OES data format in case of OpenGL ES 2.0.
Added OpenGl_Context::hasUnpackRowLength property for using GL_UNPACK_ROW_LENGTH in runtime.
OpenGl_Texture now uses GL_UNPACK_ROW_LENGTH on OpenGL ES 3.0 when necessary.
OpenGl_Texture::InitCubeMap() now allows uploading vertically-stacked cubemaps
without GL_UNPACK_ROW_LENGTH requirement.
Added "#define occLight_Index(theId) 0" workaround allowing to compile
a single light source PBR shading program on OpenGL ES 2.0,
as it disallows non-constant index expressions (even trivially deducable at compile-time).
PBR lookup table is now automatically resized to RGBA format
when RG texture format is unsupported (OpenGL ES 2.0).
OpenGl_ShaderManager now allows compiling PBR shaders
using WebGL 1.0 + GL_EXT_shader_texture_lod extension.
PBR IBL baking GLSL program has been redisigned to use
if/else to avoid non-constant index expressions.
Diffuse baking implements packing float values into a temporary RGBA8 texture
as a fallback solution on WebGL 1.0 implementations supporting float textures
but not as FBO render targets.
OpenGl_PBREnvironment now uses GL_FRAMEBUFFER instead of GL_DRAW_FRAMEBUFFER
for compatibility with OpenGL ES 2.0.
Graphic3d_TextureRoot::convertToCompatible() - fixed handling of
Image_Format_BGR and Image_Format_BGRA formats.
OpenGl_Texture - added error message for unsupported pixel format;
error messages have been extended by resource id.
OpenGl_Texture::InitCubeMap() now does not release cubemap
on mipmaps generation failure.
Image_PixMap::ImageFormatToString() - added method returning name of pixel format.
1) Add empty constructor for Poly_Triangulation(),
2) Add Poly_Triangulation::HasGeometry() method to check that triangulation has any geometry.
3) Add possibility to cache bounding box in Poly_Triangulation and use it later in case of empty triangulation.
4) Add Poly_Triangulation::MinMax() to extends input box with bounding box of triangulation.
5) Add Poly_Triangulation::UpdateCachedMinMax() to cache min - max range of this triangulation with bounding box of nodal data.
6) Add virtual Poly_Triangulation::computeBoundingBox() to calculate bounding box of nodal data.
7) Update BRepBndLib::Add/AddOptimal/AddOBB algorithms to check empty triangulation and use cached box in this case.
8) Update BRepGProp::roughBary/surfaceProperties/volumeProperties to skip empty triangulation.
9) Remove additional myBox from RWGltf_GltfLatePrimitiveArray and some hack to save this box as nodes of base Poly_Triangulation.
10) Cache min-max range from JT file during its parsing
Error messages in TKOpenGl package have been improved to format
GLenum values as string constants or hex values.
OpenGl_VertexBuffer::init() now logs a message with error details
instead of just returning Boolean flag.
Multiple changes in BRepOffset_MakeOffset algorithm:
- correct fusing vertices;
- correct building intersection edges;
- correct intersecting new edges in 2D;
- correct building wire on a new face;
- correct building history.
- moved creating of V3d_View::myTrihedron from constructor to first attempt of displaying or calling it;
- moved creating of V3d_Viewer::myRGrid and V3d_Viewer::myCGrid to to first attempt of displaying or calling them;
- renamed V3d_Viewer::IsActive() to V3d_Viewer::IsGridActive();
- redefined V3d_View::Trihedron() and V3d_Viewer::Grid() by adding new argument toCreate
for opportunity to check the existence of the objects without their recreating.
Fixed multitouch input.
Module is now exported with global functions hidden via MODULARIZE
as global object OccViewerModule created by createOccViewerModule().
Global Module setup has been moved to occt-webgl-viewer.js.
Use EMSCRIPTEN_KEEPALIVE attribute istead of listing C functions via EXTRA_EXPORTED_RUNTIME_METHODS.
WasmOcctView now exports static methods as Module functions using EMSCRIPTEN_BINDINGS.
Standard_ASSERT_DBGBREAK_() is now defined using emscripten_debugger().
- Added checking for null objects
- Added support to find layers according to visible attr
- Fixed problem with same names of layers:
Now, layers are grouped by names and visibility parameter
Extrema_GenExtCS.cxx : added solution refinement, if solution seems to be "bad" according to special criteria.
Extrema_FuncExtCS.cxx : "cosmetic" modifications
BOPAlgo_PaveFiller_3.cxx : adding control of shape index to prevent exception in ShapeInfo
bugs/moddata_3/bug32058 : new test
Shadowmap sampler is now passed as a dedicated argument
to occDirectionalLightShadow() to workaround strict GLSL syntax validator.
Fixed texture coordinates clamping range.
Shadow antialiasing is disabled on OpenGL ES 2.0.
Graphic3d_RenderTransparentMethod has been extended by Graphic3d_RTM_DEPTH_PEELING_OIT,
which is handled by OpenGl_LayerList::renderTransparent().
OpenGl_FrameBuffer::Init() now does not silently ignore unknown color attachment format and return failure.
OpenGl_FrameBuffer::InitWrapper() - added constructor wrapping existing color textures.
v3d/transparency/oit: test case added
Information about normals are stored in BinOCAF, XmlOCAF, BRep and BBRep (in case of triangulation-only Faces).
Versions of formats have been changed (11 for TDocStd, 4 for BRep Shape and 3 for Binary BRep Shape)
theWithNormals parameter added to BRepTools::Write()
IsWithNormals()/SetWithNormals() function added to BRepTools_ShapeSet
-normals/-noNormals option added to StoreTriangulation DRAW command
-normals/-noNormals option added to writebrep DRAW command
Tests for writing to brep/binary brep/BinXCaf/XmlXCaf added
Test for StoreTriangulation options -normals/-noNormals added
Draw::ParseOnOffIterator() - added auxiliary wrapper over Draw::ParseOnOff() for more compact syntax.
strncasecmp() definition for msvc compilers has been moved to Standard_CString for consistency with strcasecmp().
vmanipulator command has been refactored to use more straightforward parser.
vmanipulator now accepts "-adjustPosition {0|center|location|shapeLocation}" options
adjusting position to object's AABB center (existed before), object's local transformation or TopoDS_Shape location.
