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_ShadowMap - added new class storing shadow map FBO with parameters.
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.
Base normal map support has been implemented in path tracing (just geometry normal replacement).
Smooth normal adaptation has been implemeneted in order to avoid black areas artefacts during path tracing.
Tangent normal space calcuation has been moved to separate unified function.
Tangent space orthogonalization algorithm has been changed in order to handle all orientations and combinations of UV coordinates.
"Range" parameter of point light sources (positional and spot) concidering in PBR has been added.
Angular attenuation parameter of spot light in PBR has been reimplemented based on existing "concentration" parameter.
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.
Generation of header files from resource files was added to CMake and genproj procedures.
Message_MsgFile has been extended with new method ::LoadFromString()
for loading messages from embedded resources.
Message_MsgFile::LoadFromString() is now a preferred way
for loading message resources by application
as alternative to environment variables.
TObje/TObj.msg is now embedded into TObj_Application.cxx.
TObj_Application now loads its global messages
on instantiation of the first class instance.
UnitsAPI/Lexi_Expr.dat now completely embedded into Units_Lexicon.cxx.
UnitsAPI/Units.dat now embedded into Units_UnitsDictionary.cxx
but can be regenerated from resource file.
The definition of the following units have been removed:
benne à charbon, calorie (diététique).
Unused message files XSMessage/IGES.us and IGES.fr have been removed.
Related code IGESData.cxx has been removed as well.
XSMessage/XSTEP.us is now embedded into Interface_StaticStandards.cxx
and used for fallback initialization in case when file resources
defined by CSF_XSMessage environment variable are missing.
SHMessage/SHAPE.us is now embedded into ShapeExtend.cxx
and used for fallback initialization in case when file resources
defined by CSF_XHMessage environment variable are missing.
Duplicating code has been removed from ShapeProcess_OperLibrary.cxx.
Shaders/Declarations.glsl and Shaders/DeclarationsImpl.glsl
are now embedded into OpenGl_ShaderProgram.cxx.
CSF_ShadersDirectory is no more required for using OCCT 3D Viewer.
Ray-Tracing GLSL programs from Shaders are now embedded into OpenGl_View_Raytrace.cxx.
File resources are still used instead of embedded programs
when CSF_ShadersDirectory is defined, but this functionality
is intended for OCCT development.
Enumeration Graphic3d_ShaderProgram::ShaderName_Phong
demonstrating custom GLSL program usage has been removed.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
