# Conflicts:

# src/SelectBasics/SelectBasics_SensitiveEntity.hxx
Added const for method BVH_Builder::Build().
Added missing Standard_OVERRIDE to overridden methods.
Merged code from .lxx in BVH package directly into .hxx headers.
OpenGl_PrimitiveArray::Render() - removed obsolete code, which become redundant (and broken)
after moving rendering of transparent objects into OpenGl_LayerList::renderTransparent().
Graphic3d_RenderingParams - introduced new parameters CameraFocalPlaneDist and CameraApertureRadius managing DOF effect.
TKOpenGl - added new ray generation logic to RaytraceBase.fs.
vrenderparams command - added -focal and -aperture parameters.
OpenGl_View.hxx - function for ray generating was split into two functions (ray tracing and path tracing).
OpenGl_View_Raytrace.cxx - fixed interaction between adaptive sampling and stereo camera
OpenGl_ShaderProgram::Initialize() - precision declarations have been moved
after the list of enabled extensions.
Declarations.glsl - the fragment shader outputs have been re-declared as array
for proper assignment of default locations (draw buffers).
OpenGl_FrameBuffer - GL_HALF_FLOAT is now used instead of GL_HALF_FLOAT_OES on OpenGL ES 3.2+.
OpenGl_Texture - fixed initialization of Image_Format_RGB32 image format on OpenGL ES 3.0+.
Use Quantity_ColorRGBA instead Quantity_Color in XCAFDoc_Color attribute
Add methods to color tool for processing RGBA
Update Color driver
Update Draw commands
Weighted, Blended Order-Independent Transparency algorithm has been added rasterization pipeline.
In contrast to classical blending transparency it makes transparent objects look independent
from point of view. It also gives better depth occlusion when being used together with a weight factor
based on value of a GL depth buffer. The feature supports desktop OpenGL, OpenGL ES 3.0, ANGLE
and can be used together with MSAA on desktop GL.
To be used it require availability of:
1) Shaders pipeline.
2) Floating point color format for framebuffer (GL_ARB_color_buffer_float).
3) Multiple render targets (GL_ARB_draw_buffers).
Patch does not modify API and does not require application porting.
It adds new rendering options to Graphic3d_RenderingParams structure:
a) Transparency method from enumeration.
b) Scalar factor [0-1] controlling influence of a fragment's depth to its visibility.
Patch also simplifies processing of transparent objects for standard method:
rendering priority of transparent graphical structures is managed automatically,
therefore there is no need to care about it at application's side.
OpenGl_AspectMarker::Resources::BuildSprites(), fixed uninitialized theMarkerSize
in case if aspect has been already initialized for specified marker type.
Draw Harness command vaspects has been extended with new options -setMarkerType and -setMarkerSize.
Graphic3d_RenderingParams::RenderResolutionScale - added new option
defining scale factor for allocating off-screen rendering buffers
relative to native resolution of window buffer.
Scale factor can be below 1.0 (lower resolution) or higher (as analog of super sampling),
but can not be combined with MSAA settings.
Draw Harness command vrenderparams has been extended with option -rendScale
managing introduced option Graphic3d_RenderingParams::RenderResolutionScale.
vcaps has been extended with option -useWindowBuffer for managing
OpenGl_Caps::useSystemBuffer option.
vrepaint has been extended with option -immediate
for testing immediate layer redraw
OpenGl_View::blitBuffers() - eliminate compiler warning on Android
Existing OCCT path tracing engine used very simple additive material (BSDF) model, so it was possible to reproduce
behavior only of very basic materials such as metal, glass, or plastic. However, some important in CAD industry
materials like car paint or ceramic could not be modeled well. In this patch, OCCT BSDF was significantly improved
by replacing additive model with two-layered scattering model. Therefore, we have base diffuse, glossy, or transmissive
layer, covered by one glossy/specular coat. The layers themselves have no thickness; they can simply reflect light or
transmits it to the layer under it. Balancing different combinations of layer properties can produce a wide range of
different effects. At the same time, disabling the first (coat) layer allows to keep full compatibility with previously
supported scattering model. All new parameters are available via 'vbsdf' command.
Location of new sample for few material examples:
samples\tcl\pathtrace_materials.tcl
Fix shader compilation issue.
Fix test case sample_ball_alpha.
Shaders_PathtraceBase_fs.pxx - regenerate resource from origin
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
# Conflicts:
# dox/dev_guides/upgrade/upgrade.md
Fixed uninitialized fields in several classes.
Body of trivial methods have been moved to class definition (header file).
Ensure that non-primitive types are returned by reference, when possible.
Removed unused class Prs3d_PlaneSet.
To read only visible roots from IGES file in the XCAF document Test Harness command "ReadIges" was modified to take into account value of the Test Harness parameter "read.iges.onlyvisible".
- Add the flag UseInfini in the method BRepOffset_Tool::EnLargeFace, defining whether it is needed to use infinite enlarge of a face or not.
- Add the method TopExp::MapShapesAndUniqueAncestors().
- Increase the value of extension in EnlargeGeometry to provide proper intersection of adjacent faces.
Generation of 3D-steps shorter than 3D tolerance has been allowed in the fix to build Walking-line.
Now, 3D-step is limited by Precision::Confusion value.
AIS_InteractiveContext::Load() now loads the object regardless specified selection mode and decomposition flag.
AIS_InteractiveContext::Load() and ::KeepTemporary() now register object in the Viewer
in the same way as ::Display() does.
Draw Harness command vdisplay has been extended with new flag -erased to load object into context in erased state.
