Dear Open Source developer I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate. You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it. With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development. With many thanks for your participation, Benno Luthiger PS: The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/. We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_de.html for registration to this mailing list. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

Ahha, some more bad coding from me. Argh. Replace BoxVisibility in DXObjectUtil.cpp (starts on line 126) with this: int __fastcall BoxVisibility(TDXPoint Point,TDXVector Front,TDXBoundingBox* Box, float AngleViewed,float MaxViewRange) { //Check Center TDXPoint Pointing = Box->Center; Pointing = Pointing - Point; if(TDXVector(Pointing).LengthNS()>MaxViewRange*MaxViewRange) return OUT_VIEW; float Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return IN_VIEW; //Check 8 corners Pointing = Box->Center + TDXPoint(-Box->LengthX,-Box->LengthY,-Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(-Box->LengthX,-Box->LengthY,Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(-Box->LengthX,Box->LengthY,-Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(-Box->LengthX,Box->LengthY,Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) Pointing = Box->Center + TDXPoint(Box->LengthX,-Box->LengthY,-Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(Box->LengthX,-Box->LengthY,Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(Box->LengthX,Box->LengthY,-Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; Pointing = Box->Center + TDXPoint(Box->LengthX,Box->LengthY,Box->LengthZ)*Box->World; Pointing = Pointing - Point; Angle = TDXVector(Pointing) ^ Front; if(Angle<0) Angle = -Angle; if(Angle<=AngleViewed) return PART_VIEW; //After all this it's outside return OUT_VIEW; } Note: if it still doesn't work reply and I'll give you the DXMath units to try to fix it again. :-( ----- Original Message ----- From: "wayne" <lov...@16...> To: <ris...@ho...> Sent: Friday, August 24, 2001 10:07 PM Subject: Why I can't install this component? > can't compile > [C++ Warning] transip.h(241): > W8022 'CTransInPlaceFilter::Transform(IMediaSample *)' > hides virtual function 'CTransformFilter::Transform > (IMediaSample *,IMediaSample *)' > [C++ Warning] source.h(169): W8022 'CSourceStream::Run()' > hides virtual function 'CBasePin::Run(__int64)' > [C++ Error] DXObjectUtil.cpp(136): E2285 Could not find a > match for 'TDXMatrix::TDXMatrix(const TDXMatrix)' > [C++ Error] DXObjectUtil.cpp(136): E2342 Type mismatch in > parameter 'O' (wanted 'TDXMatrix', got 'TDXMatrix') > [C++ Error] DXObjectUtil.cpp(142): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(148): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(154): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(159): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(165): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(171): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > [C++ Error] DXObjectUtil.cpp(177): E2094 'operator+' not > implemented in type 'TDXPoint' for arguments of > type 'TDXMatrix' > |
