- class Graphic3d_HatchStyle is added to provide a possibility to set up custom and predefined hatching;
- added the ability to set custom hatch patterns through bitmaps;
- test case for issue #28107
Patch extends GL-state caching mechanism of OpenGl_Context by new methods.
The methods allow setting/inquiring polygon rasterization and hatching modes:
- OpenGl_Context::SetPolygonMode
- OpenGl_Context::SetPolygonHatchEnabled
- OpenGl_Context::SetPolygonHatchStyle
With these methods OpenGl_Text is able to configure shading as necessary.
And this configuration is done irrespectively of currently defined face aspect.
Code of OpenGl_Workspace is also modified to use these methods as well.
Porting notes:
- OpenGl_LineAttributes now require OpenGl_Context instance for calling GL API.
- OpenGl_LineAttributes has new flag IsEnabled, it turns on/off hatching without changing the hatch type.
By default this flag is turned on and can be never modified for compatibility with old code.
- OpenGl_LineAttributes is not anymore a field of OpenGl_Workspace::myLineAttrib.
This resource is directly created by an OpenGl_Context instance on demand.
If you use custom implementation of hatch patterns please create and share custom resource
under resource-key "OpenGl_LineAttributes" in corresponding OpenGl_Context before using
methods SetPolygonHatchEnabled, SetPolygonHatchStyle.
Quantity_ColorRGBA has been introduced as convenient structure holding Vec4 for OpenGL.
Graphic3d_PolygonOffset has been added as replacement for TEL_POFFSET_PARAM.
Duplicating definition of Hatch Styles TEL_HS_*** has been removed;
Aspect_HatchStyle enum now follows values of TEL_HS_*** for compatibility.
TelCullMode enum has been removed.
Aspect_AspectLine has been merged into Graphic3d_AspectLine3d.
Aspect_AspectMarker has been merged into Graphic3d_AspectMarker3d.
Aspect_AspectFillArea has been merged into Graphic3d_AspectFillArea3d.
Graphic3d_CAspectFillArea have been removed.
OpenGl_AspectLine now stores Graphic3d_AspectLine3d as class field.
OpenGl_AspectMarker now stores Graphic3d_AspectMarker3d as class field.
OpenGl_AspectText now stores Graphic3d_AspectText3d as class field.
OpenGl_AspectFace now stores Graphic3d_AspectFillArea3d as class field.
Graphic3d_AspectFillArea3d - back face culling is now enabled by default.
TKOpenGl now relies on Graphic3d_Group::IsClosed() flag to disable face culling.
StdPrs_ShadedShape now does not modify aspect for different culling modes.
Headers InterfaceGraphic_Graphic3d.hxx, InterfaceGraphic_telem.hxx, InterfaceGraphic_tgl_all.hxx
defining obsolete structures CALL_DEF_COLOR, CALL_DEF_POINT,
CALL_DEF_MATERIAL, CALL_DEF_TRANSFORM_PERSISTENCE, TEL_POINT, TEL_COLOUR
have been removed.
Useless and broken test case bugs/vis/buc60821 has been removed.
OpenGl_Workspace::myAspectFaceApplied and myAspectMarkerApplied have been replaced
from OpenGl_AspectFace*/OpenGl_AspectMarker*
to Handle(Graphic3d_AspectFillArea3d)/Handle(Graphic3d_AspectMarker3d).
This eliminates reading from freed memory
(e.g. when OpenGl_AspectFace is allocated on stack like in OpenGl_Trihedron).
OpenGl_PrimitiveArray::drawEdges() - fix drawing non-indexed array from VBO (access violation due to NULL handle).
AIS_Dimension::DrawArrow() - added missing initialization of 3D arrow aspect.
AIS_Manipulator::Compute() now creates dedicated Face Aspect for each axis.
V3d_CircularGrid, V3d_RectangularGrid now create dedicated line aspects with different color.
AIS_InteractiveObject::SetMaterial() - do not modify global ShadingAspect.
OpenGl_Clipping - do not setup clipping planes using FFP when it is disabled.
OpenGl_ShaderManager - apply 2d texture coordinates transformation in GLSL programs.
OpenGl_Context::SetTextureMatrix() - move texture matrix assignment from OpenGl_Workspace::setTextureParams() to OpenGl_Context.
Add test case demo/samples/dimensionsglsl with FFP turned OFF.
Add test case v3d/glsl/texture_trsf applying texture transformation.
Small correction of test case for issue CR26122
OpenGl_LineAttributes - drop display lists for stipple lines.
OpenGl_Context - add methods OpenGl_Context::SetTypeOfLine() and OpenGl_Context::SetLineWidth() to setup line aspects.
OpenGl_ShaderManager::prepareStdProgramFlat() - support new bit OpenGl_PO_StippleLine.
vaspects command - add -setlinetype option.
OpenGl_Caps::contextCompatible - new option to request compatibility/core OpenGL profile.
OpenGl_Window - request core profile when requested (WGL and Cocoa).
OpenGl_Context::CheckExtension() - retrieve extensions using glGetStringi().
OpenGl_Context::init() - set backward-compatible functions to NULL within core profile:
core11, core15, core20, core32back, core33back, core41back, core42back, core43back, core44back.
OpenGl_Context::BindDefaultVao() - create default VAO required for core profile.
OpenGl_Context::ReadGlVersion() - make method public.
OpenGl_ShaderManager - create programs using GLSL version 150 when available.
OpenGl_VertexBuffer, OpenGl_ShaderProgram, OpenGl_ShaderObject - use
functions set from core profile instead of compatibility.
TKOpenGl - escape deprecated functionality with runtime checks.
Command vcaps - add option -compatibleProfile to request core/compatibility profile.
NIS_View - prevenr rendering within Core profile (unsupported).
Test case for issue CR25854
Aspect_GraphicCallbackStruct::IsCoreProfile - add new field to the struct for NIS
All inclusions of "config.h" were removed.
All places where macros defined by config.h were checked and removed
Small corrections for mac os.
Unused code in file OSD_Disk.cxx was removed.
Unused macros and includes were removed from samples and code.
Added necessary includes for MacOS.
Correct new additional compilation warning on Linux platform.
Fix for error in OSD_Chronometer on Debian70/Fedora18
OpenGl_Element destruction and resource deallocation methods now accept
a pointer to OpenGl_Context instead of a handle to avoid double deletion
of the context.
