Handled __EMSCRIPTEN__ macros to:
- Workaround atomics (__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 is undefined, but GCC atomics are provided).
- Suppress non-standard header <sys/signal.h> warning.
- Return OSD_LinuxREDHAT.
- Avoid inclusion of XLib headers.
- Skip fontconfig library.
- Enable EGL+GLES path (translated by Emscripten into WebGL).
- Skip eglCreatePbufferSurface() not implemented by Emscripten EGL.
Fixed Graphic3d_Vec4.hxx usage within Quantity_ColorRGBA.hxx.
OpenGl_ShaderManager::defaultGlslVersion() now prefers GLSL 300 es when WebGL 2.0 is available,
as there no any OpenGL ES greater than 3.0 emulation so far.
Shaders_Declarations.glsl - added workaround for GLSL compilation on WebGL 1.0
by defining Light properties accessors as macros instead of functions
('[]' : Index expression must be constant).
OpenGl_FrameBuffer::Init() - added workaround for initialization of GL_DEPTH24_STENCIL8
depth-stencil attachment on WebGL 1.0 + GL_WEBGL_depth_texture extension.
OpenGl_Context::Vec4FromQuantityColor() now considers myIsSRgbActive flag
to handle use case, when Immediate Layer is drawn directly into window buffer,
which is not sRGB-ready.
Added new sample - OCCT WebGL viewer.
Font_FTFont::FindAndCreate() now loads embedded fallback font within Font_StrictLevel_Any level.
Font_FontMgr::FindFont() - fixed misprint in message, and customized message for range fallback error.
Font_FontMgr - added one more fallback Korean font for Linux.
vfont command has been extended with options to clear Font Manager content.
When collecting the points to build plane use the points on the curve instead of poles (in case of BSpline and Bezier curves).
Side effect changes:
Changes in Geom2dHatch_Elements are to increase the chance of correct 2d classification (by the means of Geom2dHatch_Classifier) by taking more than just one point on the edge to construct the classification ray and by checking if this ray is not tangent to the edge itself.
AIS_ConnectedInteractive::connect() now throws exception on connecting already displayed object.
AIS_TextLabel::AcceptDisplayMode() - added missing Display Mode filter.
Commands vconnect, vconnectto and vaddconnected have been corrected to
replace dispalyed AIS_Shape with AIS_ConnectedInteractive in context.
Introduced new attribute XCAFDoc_VisMaterial storing visualization material definition.
XCAFPrs_Style has been exteneded Material() property.
XCAFPrs_AISObject::DispatchStyles() maps new XCAFPrs_Style::Material() property onto graphics aspects.
RWGltf_GltfJsonParser and RWObj_CafReader now put Material definition into XCAF document instead of a color label.
RWGltf_MaterialMetallicRoughness - added missing properties AlphaMode, AlphaCutOff and IsDoubleSided;
fixed default values in constructor for Metallic and Roughness.
Added commands XGetAllVisMaterials, XGetVisMaterial, XAddVisMaterial,
XRemoveVisMaterial, XSetVisMaterial, XUnsetVisMaterial for working with
new visualization materials table in the document.
OpenGL rendering is now done into sRGB framebuffer.
OpenGl_ShaderManager::prepareStdProgramFboBlit() has been extended
by programs resolving MSAA texture and applying gamma correction as fallbacks.
Quantity_Color definition has been modified to store RGB components
in linear color space within Quantity_TOC_RGB type.
Standard colors defined by Quantity_NameOfColor enumeration has been updated accordingly.
New Quantity_TOC_sRGB type has been introduced to handle RGB components in non-linear sRGB color space.
OpenGl_TextureFormat class definition has been moved to dedicated files.
New method OpenGl_TextureFormat::FindFormat() replaces OpenGl_Texture::GetDataFormat().
New method OpenGl_TextureFormat::FindSizedFormat() replaces OpenGl_FrameBuffer::getColorDataFormat()
and OpenGl_FrameBuffer::getDepthDataFormat().
Graphic3d_TextureRoot::IsColorMap() - introduced new property defining
if RGB(A)8 image formats should be loaded as sRGB(A) textures or as data RGB(A) textures.
OpenGl_Texture initialization methods have been extended with new theIsColorMap argument.
vreadpixel - added argument -sRGB printing color in sRGB color space.
Test cases have been updated to new sRGB rendered results.
The table of named colors has been compressed and moved out
from Quantity_Color.cxx into Quantity_ColorTable.pxx.
Quantity_NameOfColor - grayscale enumeration values have been re-ordered to fix discontinuity.
Duplicating colors has been merged within enumeration:
CHARTREUSE=CHARTREUSE1, GOLD=GOLD1, GREEN=GREEN1, ORANGE=ORANGE1,
ORANGERED=ORANGERED1, RED=RED1, TOMATO=TOMATO1, YELLOW=YELLOW1.
Added aliases to several other common colors:
BLUE=BLUE1, CYAN=CYAN1, LIGHTCYAN=LIGHTCYAN1, MAGENTA=MAGENTA1.
Quantity_Color class definition has been cleaned to follow OCCT coding style.
Quantity_Color now stores NCollection_Vec3<float> as class field instead of separate components.
Removed unused class Quantity_ColorDefinitionError.
New methods Quantity_Color::Convert_LinearRGB_To_sRGB() and Quantity_Color::Convert_sRGB_To_LinearRGB()
converting RGB components from linear to non-linear sRGB colorspace and vice versa.
Image_PixMap::PixelColor() and Image_PixMap::SetPixelColor() methods have been extended
with an optional argument for performing linearization/delinearization of 8-bit sRGB pixel formats.
Draw Harness command AISColor has been corrected to take color name instead of enumeration index.
1. Correct building history: the case of closed spine.
2. Rollback method GeomFill_CorrectedFrenet::InitInterval - correct processing singularities on spine.
3. Correct test cases.
Changes for using Axis Placement(not used during creation of assembly) as transformation for root Shape Representation.
Test for bug 29068 and auxilary command are added.
When splitting the shell/face with internal faces/edges use the 'internal' criteria of the face to choose the way to create loops.
Side effect changes:
- When performing Boolean operation - move the objects located far from Origin to the Origin to increase the accuracy of intersections.
1. BRepLib.cxx: calculation of 2d tolerance is changed in method BRepLib::SameParameter(Edge..)
2. Geom2dConvert.cxx: incorrect comparing
"SquareDistance < tolerance"
is replaced by
"SquareDistance < tolerance*tolerance"
because tolerance is linear value.
1. src\BRepSweep\BRepSweep_NumLinearRegularSweep.cxx
Fix bug by adding result in list of generated shapes, if initial shape is vertex, edge or face.
2. src\BRepLib\BRepLib.cxx
Add protection against treatment not geometric edge in BRepLib::UpdateInnerTolerances(...)
3. Add test case for bug and correct test for bug 30346 according to new behavior of algorithm
Methods of classes Geom_ElementarySurface, Geom_Conic, and Geom2d_Conic setting or returning values of fields are made inline and return const& to avoid copying
Updated OCC logo.
Replaced some external links to https.
Added references to VS2019 support.
Added glTF, OBJ, IFC, JT into listing within appropriate sections.
Replaced dead URLs.
Fixed misleading information.
BRepMesh_ModelHealer - recognize a small face with 1 wire and 2 small edges as a face for refinement.
BRepMesh_DefaultRangeSplinner - reduce tolerance on tiny faces to improve the meshing results.
Added new test cases: bugs mesh bug25044_*.
Existing test cases updated to reflect improvements.
Modifications added to upgrade guide:
- Font_FontAspect enum digits have different values (0030439),
- Graphic3d_PolygonOffset default value change (0030716),
- AddZLayer inserts layer before Graphic3d_ZLayerId_Top, the previous implementation inserted it above all layers(0030668).
Undefined behavior caused by left shift operations in TopLoc_Location::HashCode() function is fixed.
HashCode() function overload for Standard_Size type is made available only if Standard_Size and "unsigned int" are different types (it is usually true for 64-bit platforms). The overload for "unsigned int" is made simple non-templated function (so it behaves the same on 32-bit and 64-bit platforms).
HashCode() function overload for Standard_Utf32Char type is made available only if Standard_Utf32Char and "unsigned int" are different types (it is needed for some old compilers).
