vdisplay no longer opens BREP file in case if Draw variable is not found.
Draw::Get() unused Complain argument has been removed from method definition.
Added Draw::GetExisting() and DBRep::GetExisting() commands never performing picking.
A new tool for debugging shaders has been introduced.
The new method OpenGl_ShaderProgram::UpdateDebugDump() allows dynamically
dumping/restoring certain shader program (vertex and fragment shaders) to/from external file.
The file name is generated from the program's name with suffix ".vs" or ".fs" for shader type.
The environment variable CSF_ShadersDirectoryDump specifies the folder for dumps.
If the file does not exist (first frame), then it is automatically saved.
When the file date/time is changed in comparison with recent cached date,
then the file will be automatically loaded from external file,
thus this file can be modified in any editor.
OpenGl_ShaderManager now generates a human-readable resource ids for standard GLSL programs.
Draw Harness command vshader has been extended with arguments -list,-dump and -reload
for debugging shaders within OpenGl_Context.
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.
OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).
vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.
ViewerTest::ParseColor() now parses RGBA color.
Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
OpenGl_View::runPathtrace() has been extended with alternative multi-pass
Adaptive Screen Sampling mode, not relying on atomic floating point operations.
Although atomic operations on floats allows single-pass rendering,
such operations leads to instability in case of different calculation order.
Atomic float operations are also currently supported only by single GPU vendor.
Fixed GLSL compilation on Intel drivers (follow ARB_shader_image_load_store
specs rather than EXT_shader_image_load_store).
Graphic3d_RenderingParams::AdaptiveScreenSamplingAtomic option has been added
to activate 1-pass Adaptive Screen Sampling mode when supported by hardware.
vfps command has been extended with -duration argument allowing to limit command execution time.
vactivate command has been extended with -noUpdate argument.
OpenGl_TileSampler has been refactored to better describe its logic:
- Offset image now defines tile index instead of offset to tile origin.
- Added 2D array defining the number of times to sample tile for straight-forward debugging.
Graphic3d_RenderingParams has been extended with property
RayTracingTileSize for testing various tile configurations.
Default behavior is the following:
- Target number of tiles (e.g. upper limit per frame): 256
- Tile size: 32x32.
OpenGl_View::runPathtrace() has been split into two methods per rendering stage.
OpenGl_Texture::Init() now returns FALSE immediately on 0 input dimensions.
Added Image_PixMapTypedData template class allowing to work with image data of known pixel format.
Occurrences of removed method vtkDataArray::InsertNextTupleValue() have been replaced by InsertNextTypedTuple().
Fixed misprint in vtkTypeMacro usage for class IVtkTools_ShapeObject.
Patch #0030452 (SelectMgr_ViewerSelector::Deactivate() raises exception when called twice) has been propagated to IVtkOCC_ViewerSelector.
OpenGl_ShaderObject::LoadAndCompile() - added method combining Load() and Compile() with optional error logging.
OpenGl_ShaderProgram::Link() now logs failures by default.
Removed unused SelectMgr_SOS_Sleeping enumeration value.
SelectMgr_ViewerSelector::Deactivate() now checks activation status before updating tolerance map.
Two classes TDataXtd_Presentation and TPrsStd_AISPresentation were improved so that they accept a list of selection modes.
A new non-regression test is added: caf presentation N1
Font_FontMgr has been redesigned to:
- Store fonts in a map instead a list.
- Allow mapping multiple fonts to a single alias.
- Log informative message about usage of non-requested font (fallback).
- Register all font files within standard folders on Linux when "fonts.dir" is not found.
- Prefer specific alias ("serif") as default fallback font instead of arbitrary one in a system.
A couple of obsolete and broken font aliases have been removed;
instead, new aliases of fonts popular on Linux platform have been added.
Font_NameOfFont.hxx has been extended with more neutral aliases
"monospace", "serif", "sans-serif", "cjk" and "korean".
Font_FontAspect enumeration values have been renamed Font_FA_ -> Font_FontAspect_
with old values preserved as alias.
Font_SystemFont has been extended with a list of paths to Font_FontAspect styles,
so that entire Font Family is now defined within a single Font_SystemFont instance.
Non-resizable fonts are now ignored by Font Manager.
Add new command "vstatprofiler" to manage rendering parameters and print them.
If there are some input parameters - print corresponding statistic counters values,
else - print all performance counters set previously.
Frustum culling is now managed by Graphic3d_RenderingParams::FrustumCullingState flag
and can be switched into Graphic3d_RenderingParams::FrustumCulling_NoUpdate state
useful for debugging the algorithm.
Draw Harness command vrustumculling has been replaced by vrenderparams -frustumCulling.
1) Added method Graphic3d_Camera::FrustumPoints() returning corner points of camera frustum.
2) Refactored methods OpenGl_BVHTreeSelector::isFullOut(...) and OpenGl_BVHTreeSelector::CacheClipPtsProjections()
3) Changed computation algorithm of frustum planes (build them by corner points)
4) Added interactive object AIS_CameraFrustum to draw camera frustum.
5) Extended Draw command "vcamera" with option displaying camera frustum.
When DRAW on Windows is launched with option -c, the command is now properly transferred to Tcl thread (separate thread that runs Tcl interpretor on Windows except when DRAW is run in batch mode) for execution, instead of being evaluated in the main thread.
Execution of DRAW in batch mode (option -b) is fixed by enabling proper initialization of the Tcl interpretor and replacement of backslashes in path to startup script by straight slashes on Windows in that mode.
Declaration of global variables used for communication of console command between threads is moved to Draw_Window.hxx to ensure consistency.
Function wscpy_s is used instead of memcpy to avoid possible buffer overrun.
Implementation of method "IsDeleted(...)" for MakeRevol and MakePrism algorithms.
Problem (exception) occurs during history building and was caused by an attempt to obtain generated shape for subshape, which was really "deleted" by algorithm - this input subshape and its possible generated shape was not used in result.
OpenGl_Context::MakeCurrent()/OpenGl_Context::IsCurrent() have been modified to NOT fail
in case if myWindow is EGL_NO_SURFACE (valid off-screen rendering case within EGL).
OpenGl_GraphicDriver::InitEglContext() now finds EGL surface config in case if it has not been passed by argument.
OpenGl_Window constructor now allows wrapping an off-screen rendering surface EGL_NO_SURFACE.
However, it still creates a dummy surface eglCreatePbufferSurface() to workaround bugs in some GLES drivers (Vivante GC2000).
V3d_View::SetWindow()/V3d_View::MustBeResized()/V3d_Viewer::SetViewOn() have been modified
to avoid implicit View redraw (leading to undefined behavior/crashes in case if rendering
should be done into default FBO defined right after V3d_View initialization).
Methods IsParallel() and SetParallel() have been added to BVH_Sorter, BVH_DistanceField and BVH_BuilderTransient to control parallel execution on low-level.
Fix compilation errors for old compilers without support of c++11 (std::begin, std::end)
Explicit calls to TBB in BVH_DistanceField, BVH_LinearBuilder and BVH_RadixSorter have been replaced.
Task functors have been separated on execution and state parts for the sake of usage by OSD_Parallel.
The following changes have been made for improving the offset algorithm:
1. Multi-connexity support - intersection of the faces connected to the edge belonging to more than two faces is now performed.
2. Avoid intersection of the faces connected through internal edge.
3. Filling gaps (holes) in the splits of the created offset faces to increase possibility of creation of the closed volume from these splits.
Test cases for the issue.
Implementation of the new class *BOPAlgo_MakeConnected* for making the group of touching same-dimensional shapes connected.
Provide the material association for the first sub-elements of the input shapes.
Provide possibility to make the connected shape periodic.
Draw commands for new algorithm:
* makeconnected - make the input shapes connected or glued, performs material associations;
* cmaterialson - returns the materials located on the requested side of a shape;
* cmakeperiodic - makes the connected shape periodic in requested directions;
* crepeatshape - repeats the periodic connected shape in requested directions requested number of times;
* cperiodictwins - returns all periodic twins for the shape;
* cclearrepetitions - clears all previous repetitions of the periodic shape, keeping the shape periodic.
Documentation & test cases for the new algorithm.
Implementation of the new class *BOPAlgo_MakePeriodic* for making the shape periodic in 3D space.
Periodicity of the shape means that the shape can be repeated in any periodic direction any number of times without creation of the new geometry or splits.
The idea of this algorithm is to make the shape look similarly on the opposite sides or on the period bounds of periodic directions.
It does not mean that the opposite sides of the shape will be mirrored. It just means the the opposite sides of the shape should be split by each other and obtain the same geometry on opposite sides.
Such approach will allow repeating the shape, i.e. translating the copy of a shape on the period, without creation of new geometry because there will be no coinciding parts of different dimension.
Draw commands for the new algorithm:
* makeperiodic - makes the shape periodic in required directions;
* repeatshape - repeats the periodic shape in requested periodic direction;
* periodictwins - returns the periodic twins for the shape;
* clearrepetitions - clears all previous repetitions of the periodic shape.
Documentation & test cases for the algorithm.
