Bugfixes

Compile

• Confirm which the path is C:\DXSDK for DirectX files．
• Applying the SP6 to the VC6．If not, errors may happen in "TVector.h" area．
• if errors is ocurred in SETUPAPI.H during compiling，delete "HID/WBHID.*" from the "WinBasis.dsp"．
• we could not assure that this program might work well in VC7.1・BCB6 environments．If you have a trouble about this，please we recommend that you use the old version． Build of this morning is useful for resolving compiling problems of your program．

• the renewal note? memo or record concerning up-to-date source tree(VSS)

Projection Matrix

• there is information of the Projection in GRCameraData(src\Graphics\GRCamera.h), but there is no form of matrix, entering front or back disjointedly.
• Where is used the information, is src\ImpD3D\D3Render.cpp L107 around.
• As for GRCameraData, you can acquire with D3Render::camera->data.

Source Tree

Anyway, workable sample:Sample/DynaHaptic with VC6 environment is put on archieve: http://springhead.info/archive/． The latest version refers to the setting method of the VSS?．

Setting of object's position

When U use PHSolid，don't use SGFrame::SetPosture(). Because，it overwrits Solid every time． PHJoint and PHSolid is also the same． It doesn't work well if it doesn't rewrite it with PHJoint.
