0026344: Visualization - provide a support of zoom persistent selection 1) New Graphic3d_TransformPers structure for defining parameters and algorithm methods, featuring: a) application of transformation to projection and world view matrices; b) computation of model-world transformation of persistent object; c) computation of transformed bounding box of persistent object. 2) Transform persistence algorithm does not make any changes to model-world transformation of object (deals with projection and world view matrices only), thus making possible to employ local transformation in a usual way. 3) Support of BVH selection for transform persistent objects (pan, rotate, zoom, trihedron persistence only). 4) Support efficient frustum culling for transform persistent objects (pan, rotate, zoom, trihedron persistence only). 5) Support of z-fitting algorithm for world-view space transform persistent objects (rotate, zoom persistence only). 6) Rewrite usage of transform persistence structures and utilities classes: a) Replaced Graphic3d_CTransPers, TEL_TRANSFORM_PERSISTENCE by Graphic3d_TransformPers; b) Move functions from OpenGl_Utils.hxx to Graphic3d_TransformUtils.hxx; c) Extract matrix stack class from OpenGl_Utils.hxx to OpenGl_MatrixStack.hxx; 7) New class Graphic3d_WorldViewProjState to keep track of projection, world view matrices changes for a camera. 8) New test case bugs/vis/bug26344. 9) Renamed method Graphic3d_Camera::ModelViewState of to ::WorldViewState for consistency.
0024624: Lost word in license statement in source files License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast Wrong license statements corrected in several files. Copyright and license statements added in XSD and GLSL files. Copyright year updated in some files. Obsolete documentation files removed from DrawResources.
0024288: Provide flipping text for AIS_Dimensions - OpenGl_Flipper class added to provide text flipping. - Added Graphic3d_Mat4, OpenGl_Mat4 definitions for use with TKOpenGl matrix types. - Added flipping parameters for dimensions with 3D text labels at AIS_Dimension class. - Test cases.
0023457: Slow text rendering Added class Font_FTFont wrapper over FreeType face Unify collections methods NCollection_Array1, NCollection_Sequence, NCollection_Vector: declare Upper, Lower, First, Last, ChangeFirst, ChangeLast methods for all these collections. Added method NCollection_DataMap::Find() with check key is bound + retrieve value within single call interface. OpenGl_Context::ReleaseResource() method now supports lazy release of shared resources. Added class OpenGl_Font which implements textured fonts support. Added class OpenGl_TextFormatter for text formatting using OpenGl_Font. OpenGl_Text was redesigned to use OpenGl_FontFormatter. OpenGl_FontMgr class was removed. All methods related to text rendered removed from OpenGl_Display class. OpenGl_Trihedron and OpenGl_GraduatedTrihedron classes were redesigned to use OpenGl_Text. OpenGl_PrinterContext instance was moved to OpenGl_GraphicDriver fields (eliminated usage of global instance). Added test cases into 3rdparty/fonts grid to check different font styles and perform FPS tests (no automated results - requires manual analysis or snapshots comparisons). Removed unused CSF_FTGL dependency. OpenGl_Text::setupMatrix - do not apply floor for myWinZ
