Some corrections; test cases were added; coding standards in MFC samples & presentations
Request stencil buffer for Linux.
correct test cases; correct compilation errors
compilation warnings (gcc/Linux)
The purpose of this functionality is to bring a basic ray-tracing solution to existing OCCT visualization toolkit (TKOpenGL).
Currently ray-tracing visualization core supports sharp shadows, specular reflections, transparency and adaptive anti-aliasing.
However, the basis for all ray-tracing algorithms is versatile, allowing you to add new ray-tracing features easily (such as ambient occlusion).
All ray-tracing computations are performed on the GPU using OpenCL framework, allowing real-time rendering performance.
It is important to note, that real-time ray-tracing is possible using high-performance GPUs with support of OpenCL 1.1 and higher (such as NVIDIA GeForce 660 or ATI/AMD Radeon 7850).
When using low-end GPUs (such as NVIDIA GeForce 640) the ray-tracing performance may slow down significantly.
Therefore, even with NVIDIA GeForce 640 you can render scenes with the millions of triangles. The support of OpenCL-enabled CPUs and integrated graphics cards is not guaranteed.
Overall revision of of CSharp sample code:
- Pure C++ project "OCC" deleted as unnecessary
- C++/CLI project "shell" renamed to OCCTProxy and refactored to implement all required interface to OCCT functionality.
- In About dialog, date corrected in Copyright statement
- CSharp files re-layouted with 2 spaces indentation
- ReadMe converted to MarkDown format and revised
- Generation of names of views refactored to avoid calling C++ level
- Project files corrected to run on 64-bit systems
- Batch scripts refactored to use OCCT default configuration
WPF front-end added to demonstrate usage of OCCT in WPF applications.
WPF sample was modified, operation Export has been fixed
Exception "Cannot create this file", which appeared by export to image format, has been corrected.
Option "Export image to .xwd" removed.
Introduce new class Font_BRepFont for conversion of font glyph in vector format into BRep representation.
New text2brep Draw Harness command.
bottle.tcl - draw text on the bottle side using new functionality.
ViewerTest - process Delete key in 3D-Viewer to delete selected presentations.
Font_FontMgr::FindFont - return correct font when font alias and not default aspect is requested.
bottle.tcl - use prism instead of pipe
TKViewerTest - add required FreeType dependency
verase - display the list of erase objects
TKViewerTest - add required FreeType dependency for projects generation
Fixed graphic structure recompute after closing view.
Removed collector and all corresponding logic and methods from AIS_InteractiveContext.
Method AIS_InteractiveContext::Erase() now hide object from viewer without deleting resources.
Erased objects now properly recomputed after closing view.
Samples update
Removed useless method AIS_InteractiveContext::EraseMode()
Documentation update
Warnings fix
Regressions fix
Introduce Point Sprites usage.
Graphic3d_Group - drop Marker(),MarkerSet() methods - markers should be drawn using AddPrimitiveArray.
Added new Draw Harness commands vcaps, vmarkerstest.
Project file extension corrected for VS 2010/2012 solutions
Sources and resource files from Common and Interface sub-foldrs added to qmake project files from their original location.
RES_DIR environment variable redirected to the binary directory, all resource files copied there to keep the source tree intact.
RES_DIR environment variable corrected under Linux/MacOS similalry to Windows.
Makefile generation corrected under MacOS:
- filenames used as the output for the extra compilers instead of the absolute paths.
- mkdir and cp command options corrected
WNT_Window::Dump method calls were replaced with V3dView::Dump calls
Type casts were removed
Added supported image formats in file filters of Export methods, edited documentation for Image_AlienPixMap class
Supported image formats filter for 2dsample was extended
void FreeTexture() in OpenGl_TextureBox.cxx - avoid possible NULL-pointer dereference
after debug x64 compilation the executable viewer3d had been moved to the bin folder. now executable viewer3d located in bind folder.
Removal of VoxelClient
VoxelDemo sample is redesigned so that it doesn't require compilation of OpenGl classes. It refers to TKOpenGl.dll as to an external library.
Some minor bugs are fixed in OCAF and Viewer 3d standard MFC samples
Tcl samples moved from src/DrawResources to samples/tcl.
Scripts VisualisationDemo.tcl and ModelingDemo.tcl fixed to work on Windows.
File wing.brep moved from src/DrawResources to data/occ, and DataExchangeDemo.tcl corrected.
OCAFDemo.tcl removed, as it has little sense and referred data files are lost
Added sample Tcl script creating a model defined on the 'Open CASCADE challenge' web page
