EWDraw3D ActiveX is a powerful vector graphics ActiveX for 3D and 2D visualisation and animation. You can use it for CAD,CAM,GIS and others. The EWDraw3D ActiveX is based on Open CASCADE geometric kernel and openGL. <BR> The library is realized as a run-time Windows 32 bit OCX (ActiveX control). Either can be used with applications written in the popular Visual IDE languages such as Visual Basic, Delphi, C++ Builder , Visual C++, .NET and INTERNET <BR> Version 5.5 August 8 2008<BR> .Add Animation mode<BR> .Add Perspective view<BR> .Add SetAnimationMode to Active or Deactive Animation mode<BR> .Add SetDeviationCoefficient function to set deviation coefficient for Amnimation mode<BR> .Add SetPerspectiveMode to Active or Deactive perspective view.<BR> .Add SetCamera function to set a camera in a perspective view.<BR> .Add SetCameraAngle function to set angle of a camera in a perspective view.<BR> .Add RevolByAngle function to build revolved entity with angle degree.<BR> .Improve Boolean opration<BR> .Improve import/export for STEP or IGES.<BR> .Optimize code for display a 3D solid<BR> .Fix a bug for import STEP or IGES<BR> .Fix some bug for view<BR> Version 5.0 May 6 2008<BR> .Add IMPStep214 function to import STEP file,This function improve import speed and support color.<BR> .Add ExpStep214 function to export STEP file,This function improve export speed and support color.<BR> .Add IMPIges214 function to import IGES file,This function improve import speed and support color.<BR> .Add ExpIges214 function to export IGES file,This function improve export speed and support color.<BR> .Add Get3DSolidSection to get section from 3D solid by a plane.<BR> .Add SetMeshSectionPlan to get section from mesh by a plane.<BR> .Add CalculateNormalize function to get normalize from 3 points.<BR> .Add ProjectLineToPlan function project a line on the plane<BR> .Fix some bug for mesh<BR> .Fix some bug for zoom<BR> .Fix some bug for ToDrawScale<BR> .Fix some bug for ToDrawEllipse<BR> .Fix some bug for ToDrawEllipseArc<BR>
