1. DRAW-commands for curve/surface continuity returning were changed.
2. Output of "distmini" DRAW-command is amended.
3. Function MinMax() was moved from Standard_Real to IntPatch_ImpImpIntersection_4.gxx.
4. Incorrect computing of nbcurveC1 in Geom2dConvert::C0BSplineToC1BSplineCurve(...) function was liquidated.
Test cases were changed.
Existing method of Cylinder-Cylinder intersection computing is based on finding the analytic line (as a function of one argument) and converting one into the walking-line with set of equidistant (along the line parameter) points.
The main advantage of applied method is using adaptively computed step. Necessary step is computed into every point of the obtained walking-line. At that we receive final walking-line directly (without preliminary analytic line) and we determine moments more precisely, when it should be split (see IntPatch_ImpImpIntersection_4.gxx).
The main disadvantages is bad working this method for non-trimmed cylinders (with infinite bounds), because step value is depend on the boundaries values.
More over, new method always returns walking-line, while intersection result can be an analytic curve (lines, circle, ellipse). That is NO good. Therefore, analytic curve is computed by existing method.
In conclusion, in spite of covering almost all more often meeting cases, new method has limited application. Then we should use the existing old method.
Additionally, method MinMax() is added (see Standard_Real.hxx file). It uses into new algorithm.
Some test cases is changed according to their new behavior.
Test case for issue CR24915 is added.
Into GeometryTest_APICommands.cxx only tabulations were chaged.
"Extending" of isolines (see Geom2dHatch_Hatcher.cxx).
Small correction of test case for issue CR24915.
Implement SAT intersection tests and frustum culling algorithm using BVH trees.
New Draw command vfrustumculling to manage frustum culling.
Add test cases bugs/vis/bug24307_1 and bugs/vis/bug24307_2.
Remove CALL_DEF_BOUNDBOX and CALL_DEF_BOUNDS.
Implementation of global functions STANDARD_TYPE() for types not inheriting Standard_Transient or Standard_Persistent are eliminated.
Global functions and class methods ShallowCopy() are removed; also removed unused classes Visual3d_PickPath and Visual3d_PickDescriptor.
Global functions and class methods ShallowDump() are removed, except for classes Standard_GUID, TopLoc_Datum, and TopLoc_Location as the latter are still used in some Debug printouts.
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.
