dir^up becomes a zero vector when the view direction and up vector are parallel, producing an invalid zero-normal plane. Plane::distanceToOrigin() then asserts/aborts (CVF_ASSERT, always active). Fall back to an arbitrary axis to compute a valid right vector in this degenerate case.
* #11371 Remove GLEW dependency and use Qt's QOpenGLFunctions
Replace embedded GLEW library with Qt's native OpenGL function loading
(QOpenGLFunctions/QOpenGLExtraFunctions) to resolve Qt 6 compatibility
warnings about GLEW conflicts with qopenglfunctions.h.
- Update CVF_CALLSITE_OPENGL macro to provide QOpenGLExtraFunctions pointer
- Replace GLEW initialization with Qt OpenGL context validation
- Keep direct calls for fixed-function GL (glBegin, glEnd, glMatrixMode, etc.)
- Remove glew/ directory containing embedded GLEW source
* #11371 Remove GLU dependency to fix Windows build error
GL/glu.h conflicts with Qt's OpenGL headers on Windows due to APIENTRY
redefinition. Replace gluBuild2DMipmaps with glTexImage2D + glGenerateMipmap,
and gluOrtho2D with glOrtho.
* Refactor to deprecate existing QGLWidget derived widget
Renamed cvfqt::OpenGLWidget to cvfqt::GLWidget_deprecated
Renamed cvfqt::CvfBoundQGLContext to cvfqt::CvfBoundQGLContext_deprecated
Renamed cvfqt::OpenGLContext to cvfqt::OpenGLContext_QGLContextAdapter_deprecated
Added cvf::OpenGLUtils
* Marked existing QtMinimal and QtMultiView as deprecated
* Additional deprecated renaming
* Added missing type
* Added missing include
* Fixes to get snippets up and running before introducing new OpenGL widgets
* Added class for OpenGLInfo
* Refactored cvf::OpenGLContext and cvf::OpenGLContextGroup, and added first cut impl of cvfqt::GLWidget and cvfqt::OpenGLWidget
* Removed unused TriggerTBBCopy.txt
* Initial support for compilation on Qt6
* Added QtMinimal and QtMinimal_GLWidget
* Refactored SnippetRunner to handle utilize cvfqt::OpenGLWidget
* Removed unused code
* Fixes and workarounds from compiling on linux
* Fixes by clang-format (#11056)

Housekeeping in VizFwk in preparation for introducing support for QOpenGLWidget and Qt6
* Adjusted unit tests to changes in source code
* Use Qt5 as default and removed copying of Qt DLLs
* Removed support for Qt4
* Removed the CVF_OPENGL_ES define. If we ever want to re-introduce support fro OpenGLES/Angle it should be handled differently.
*Added include of <locale.h>
* Added target for running Glsl2Include in order to build cvfShaderSourceStrings.h
* Removed all usage of CVF_USING_CMAKE
* Removed visual studio project files
- Update the minimum required CMake version to 3.15 for Fwk folders
that might be used as top level projects.
- Remove the minimum required CMake version from projects that is just
included from other top level projects.
Since version 3.19 CMake has been warning that CMake versions below 3.5
is deprecated and support will be removed in the future. This will
silence those warning.
By removing the minimum required version check from projects that is not
intended as top level projects we avoid redundant checks and simplifies
future maintenance.
Closes#10957
* Set warning level to /W3 for MSVC to catch more warnings
* remove several excluded checks for clang
* removed several unused variables
* Hide warnings qwt
* add missing parentheses in logical expressions
* Remove double check on same logical expression
Pdm fields can contain a forward declared Pdm object without the include
file
VizFwk: Added VertexColoring shader to be able to use per vertex color
used from drawableGeo::setColorArray()
