V3d_View/Graphic3d_CView pair has been extended to define subview within the other V3d_View instance.
The initialization is done in form of V3d_View::SetWindow() taking parent V3d_View instance on input.
Subview definition includes dimensions defined as a fraction of a parent view and offset from a corner.
This scheme allows splitting window into several subviews automatically occupying entire viewport,
like splitting window into two vertial subviews (100%x50% + 100%x50%),
three horizontal subviews (33%x100% + 30%x100% + 30%x100%),
1 + 2 stacked subviews (50%x100% + 50%x50% + 50%x50%),
as well as thumbnail-alike subviews displayed on top of another larger view.
OpenGl_View::Redraw() blits content of subviews into the window within immediate redraw step.
AIS_ViewController::FlushViewEvents() has been extended
to re-calculate mouse input into local subview coordinates.
AIS_ViewController::handleViewRedraw() first redraws subviews and then parent views.
Introduced new callback AIS_ViewController::OnSubviewChanged()
to switch input focus to another subview on mouse click,
implemented by ViewerTest_EventManager (has to be done at application level).
vinit command has been extended with parameters -subview and -parent to create a subview.
In addition, view dimension arguments now can be defined as a fraction of screen size instead of pixels.
Image_PixMap has been extended to support definition of 3D bitmap (as an array of 2D slices).

Added new flag OpenGl_Caps::buffersDeepColor disabled by default.
OpenGl_Window now tries to find a RGB10_A2 pixel format using wglChoosePixelFormatARB().
OpenGl_TextureFormat::FindSizedFormat() - added handling of GL_RGB10_A2 internal format.
OpenGl_View::SetWindow() now selects preferred FBO color format basing on parameters.
OpenGl_Context::DiagnosticInformation()/OpenGl_View::DiagnosticInformation() now include
information about window pixel format / FBO texture format.
Added new enumeration Graphic3d_DisplayPriority.
Graphic3d_Layer now defines a fixed-length array of priorities.
Properties Graphic3d_CStructure::Id, Priority, PreviousPriority have been wrapped into methods.
Including system OpenGL headers has been moved from OpenGl_GlFunctions.hxx to OpenGl_GlNative.hxx.
Added OpenGl_GlTypes.hxx providing basic OpenGL 1.1 types.
Wrappers of system OpenGL 1.1 / OpenGL ES 2.0 functions have been moved to OpenGl_GlFunctions.cxx.
Avoided usage of global OpenGL functions in OpenGl package outside of OpenGl_GlFunctions.cxx.
OpenGl_FrameBuffer::Init() now creates MSAA render buffer in case if MSAA textures are unsupported.
In this case OpenGl_View::prepareFrameBuffers() creates MSAA render buffer for main content
and non-MSAA FBO for immediate content as blitting of MSAA render buffers into MSAA targets is unsupported by OpenGL ES 3.0.
env.bat.in has been corrected to include path to custom ANGLE (GLES2_DIR)
in front of Qt which might include its own older ANGLE build.
Added method V3d_View::SetImageBasedLighting() for managing IBL.
OpenGl_View implementation has been revised to handle IBL updates in a more straightforward way,

OpenGl_Buffer - added new class as a base for OpenGl_VertexBuffer, OpenGl_IndexBuffer, OpenGl_TextureBuffer.
OpenGl_TextureBufferArb has been renamed to OpenGl_TextureBuffer.
OpenGl_FrameBuffer - added initializers taking vec2i instead of (int,int) for dimensions.
OpenGl_LayerList::renderTransparent() - color mask is now set to write into Alpha channel of depth peeling FBOs.
OpenGl_View::blitBuffers() - avoid using undefined color for glClear(GL_COLOR_BUFFER_BIT) operation.
OpenGl_GlFunctions no more loads unused FFP functions.
OpenGl_GlCoreXX function tables no more defined two hierarchies with and without FFP functions,
and OpenGl_Context::coreXXback fields have been removed.
Introduced OpenGl_Context::core11ffp as more straightforward naming for obsolete FFP function set.
Graphic3d_Aspects::ToSuppressBackFaces() bool flag has been replaced by
Graphic3d_Aspects::FaceCulling() property defined by Graphic3d_TypeOfBackfacingModel enumeration.
Graphic3d_TypeOfBackfacingModel_Auto corresponds to old ToSuppressBackFaces()==TRUE;
Graphic3d_TypeOfBackfacingModel_DoubleSided corresponds to old ToSuppressBackFaces()==FALSE;
Graphic3d_TypeOfBackfacingModel_BackCulled allows enabling back face culling regardless of Graphic3d_Group::IsClosed() flag.
XCAFDoc_VisMaterial::IsDoubleSided() bool flag has been replaced by
XCAFDoc_VisMaterial::FaceCulling() property defined by Graphic3d_TypeOfBackfacingModel enumeration.
glTF reader now maps "doubleSided" material flag into
Graphic3d_TypeOfBackfacingModel_BackCulled (forced back face culling) and
Graphic3d_TypeOfBackfacingModel_Auto (e.g. practically doubleSided as there is no closed/open info in glTF).
glTF writer by default writes materials as "doubleSided" save the Graphic3d_TypeOfBackfacingModel_BackCulled property set
(in future, extra logic might written for automatically defining singleSided materials for Solid B-Rep objects).
Removed obsolete unused types V3d_TypeOfPickCamera, V3d_TypeOfPickLight, V3d_TypeOfRepresentation, and V3d_Coordinate.
Deprecated types V3d_TypeOfBackfacingModel, V3d_TypeOfLight, and V3d_TypeOfShadingModel.
Added image formats Image_Format_RGF_half/Image_Format_RGBAF_half
with manual conversion between 32-bit float and 16-bit half-float values.
PBR LUT table is now converted into GL_HALF_FLOAT_OES data format in case of OpenGL ES 2.0.
Added "#define occLight_Index(theId) 0" workaround allowing to compile
a single light source PBR shading program on OpenGL ES 2.0,
as it disallows non-constant index expressions (even trivially deducable at compile-time).
PBR lookup table is now automatically resized to RGBA format
when RG texture format is unsupported (OpenGL ES 2.0).
OpenGl_ShaderManager now allows compiling PBR shaders
using WebGL 1.0 + GL_EXT_shader_texture_lod extension.
PBR IBL baking GLSL program has been redisigned to use
if/else to avoid non-constant index expressions.
Diffuse baking implements packing float values into a temporary RGBA8 texture
as a fallback solution on WebGL 1.0 implementations supporting float textures
but not as FBO render targets.
OpenGl_PBREnvironment now uses GL_FRAMEBUFFER instead of GL_DRAW_FRAMEBUFFER
for compatibility with OpenGL ES 2.0.
Error messages in TKOpenGl package have been improved to format
GLenum values as string constants or hex values.
OpenGl_VertexBuffer::init() now logs a message with error details
instead of just returning Boolean flag.
Graphic3d_RenderTransparentMethod has been extended by Graphic3d_RTM_DEPTH_PEELING_OIT,
which is handled by OpenGl_LayerList::renderTransparent().
OpenGl_FrameBuffer::Init() now does not silently ignore unknown color attachment format and return failure.
OpenGl_FrameBuffer::InitWrapper() - added constructor wrapping existing color textures.
v3d/transparency/oit: test case added
Graphic3d_CLight::ToCastShadows() - added new property defining if light should cast shadows (ignored by Ray-Tracing).
OpenGl_ShaderManager::stdComputeLighting() now implements shadow mapping for directional lights.
OpenGl_ShaderManager::prepareGeomMainSrc() now handles copying of arrays.
OpenGl_Context::ShadowMapTexUnit() - added property defining an offset for shadow map texture units.

OpenGl_View::prepareFrameBuffers() - added resizing of shadow map FBOs.
OpenGl_View::Redraw() - added section redrawing scene into shadow map FBOs via OpenGl_View::renderShadowMap() method.
vrenderparams - added new parameters -shadowMapResolution and -shadowMapBias.
OpenGl_ShaderManager::pushLightSourceState() now pre-multiplies headlight transformation.
Built-in shading GLSL programs have been updated to remove special handling if headlight flag;
also removed redundant pre-normalization of light source direction
(already normalized implicitly by Graphic3d_CLight interface).
Graphic3d_CLight::SetHeadlight() now raises exception in case of ambient light type.
OpenGl_ShaderManager::SetLastView() - removed unused property.
Added V3d_View::SetBackgroundImage() accepting Graphic3d_Texture2D on input.
Graphic3d_CView/OpenGl_View have been modified to merge Graphic3d_CView::SetBackgroundImage()
and ::SetBackgroundCubeMap() implementations into a single method.
Graphic3d_TextureRoot::GetCompressedImage() - added new interface for fetching compressed texture image.
Default implementation detects DDS image files using Image_DDSParser parser.
Graphic3d_TextureRoot::GetImage() has been extended with new parameter
- the list of image formats supported by OpenGL driver.
Graphic3d_TextureRoot::convertToCompatible() implicitly converts
BGRA image to RGBA on OpenGL ES, which normally does not support BGR formats.
OpenGl_Caps::isTopDownTextureUV - new property defines how application defines
UV texture coordinates in primitive arrays.
OpenGl_Context::SetTextureMatrix() compares this flag with OpenGl_Texture::IsTopDown()
and automatically flips V coordinate in case of mismatch.
OpenGl_Texture now holds exact number of mipmap levels
instead of Boolean flag indicating that they are defined.
This allows loading DDS files with incomplete mipmap level set
by setting GL_TEXTURE_MAX_LEVEL to appropriate value instead of default 1000
(causing black textures in case if mipmap levels are not defined till 1x1).
Fixed order of texture coordinates transformation within GLSL program to match FFP matrix:
Rotate -> Translate -> Scale (previously Rotation was applied afterwards).
V3d_View::AutoZFit() is now called only before redraw
within methods V3d_View::Redraw() and V3d_View::Update().
Graphic3d_CView now holds Aspect_ExtendedRealitySession object.
Aspect_OpenVRSession implements new interface via optional OpenVR library.
Graphic3d_CView::ProcessInput() - added new interface method
which should be called for processing positional input (head tracking).
Graphic3d_Camera now allows setting custom stereoscopic Projection matrices.
OpenGl_Context::Camera() - context now holds Camera object
in addition to active camera matrices.
genproj.tcl has been extended to handle optional CSF_OpenVR dependency.
OpenGl_ShaderManager - metallic-roughness, emissive, occlusion
and normal texture maps are now supported by PBR.
Emissive, occlusion and normal texture maps are now supported by Phong shading model.
Path-Tracing now handles metallic-roughness and emissive texture maps.
Graphic3d_TextureUnit enumeration has been extended by
new values corresponding to supported texture maps.
OpenGl_TextureSet and OpenGl_ShaderProgram have been extended with
bitmask Graphic3d_TextureSetBits identifying texture slots read from GLSL Program
and slots defined within Texture Set to avoid undefined behavior by binding mock textures.
OpenGl_TextureSet now duplicates texture unit information to handle
textures shared across multiple slots (like Occlusion [R] + Metallic-Roughness [GB]).
OpenGl_Context::BindTextures() has been extended with active GLSL program paramter
to set mock textures to texture units used by program but undefined by texture set.
OpenGl_Workspace::ApplyAspects() has been extended with parameter to avoid bining texture set.
Metallic-Roughness shading model Graphic3d_TOSM_PBR has been implemented.
New materials descriptors Graphic3d_PBRMaterial have been added to Graphic3d_MaterialAspect.
PBR shading model requires OpenGL 3.0+ or OpenGL ES 3.0+ hardware.
Environment cubemap is expected to be provided for realistic look of metallic materials.
occLight_IsHeadlight() now returns bool instead of int.
Avoid using lowp for enumerations to workaround occLight_IsHeadlight()
ignorance on Adreno 308 caused by some GLSL optimizator bugs.
OpenGl_Texture::EstimatedDataSize() - fixed estimation for Cubemap textures.
OpenGl_Sampler::applySamplerParams() - fixed uninitialized GL_TEXTURE_WRAP_R in case of GL_TEXTURE_CUBE_MAP target.
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.

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.
V3d_Viewer::AddZLayer() has been replaced by
V3d_Viewer::InsertLayerBefore() and V3d_Viewer::InsertLayerAfter() methods
allowing to specify Layer settings and index of existing layer to insert new one before/after.
The behavior of V3d_Viewer::AddZLayer() has been adjusted to append
new Layer before Graphic3d_ZLayerId_Top
(between Graphic3d_ZLayerId_Default and Graphic3d_ZLayerId_Top).
Graphic3d_Layer now provides LayerId() property.
Graphic3d_ZLayerSettings has been extended with IsRaytracable() property;
Ray-Tracing now processes multiple layers instead of Graphic3d_ZLayerId_Default.
Moved some methods from OpenGl_View to the base class Graphic3d_CView.
Renamed classes (moved from TKOpenGl to TKV3d):
- OpenGl_Layer -> Graphic3d_Layer;
- OpenGl_BVHClipPrimitiveSet -> Graphic3d_BvhCStructureSet;
- OpenGl_BVHClipPrimitiveTrsfPersSet -> Graphic3d_BvhCStructureSetTrsfPers;
- OpenGl_BVHTreeSelector -> Graphic3d_CullingTool.
Method OpenGl_Layer::Render() has been moved to OpenGl_LayerList::renderLayer().
Standard Z-layers list definition has been moved
from OpenGl_GraphicDriver to base class Graphic3d_GraphicDriver.
Use .get() method instead of operator->() where result can be NULL.
STEPCAFControl_Reader::ReadLayers(), XCAFDoc_ColorTool,
XCAFDoc_LayerTool::SetVisibility() - fixed static functions syntax.
Graphic3d_AspectFillArea3d, Graphic3d_AspectLine3d, Graphic3d_AspectMarker3d
and Graphic3d_AspectText3d have been merged into new class Graphic3d_Aspects.
The old classes are preserved as dummy sub-classes of Graphic3d_Aspects
preserving different per-aspect defaults.
Methods IsGroupPrimitivesAspectSet(), GroupPrimitivesAspect(), FillAreaAspect(),
LineAspect() and MarkerAspect() have been removed from Graphic3d_Group.
Instead, a new method Graphic3d_Group::ReplaceAspects() has been introduced
for replacing existing group aspects.
AIS_Shape now uses new method AIS_InteractiveObject::replaceAspects()
for updating computed groups with new aspects without presentation recomputation
in places where SynchronizeAspects() is not applicable.
OpenGl_AspectFace, OpenGl_AspectLine, OpenGl_AspectMarker
and OpenGl_AspectText have been merged into new class OpenGl_Aspects.
