I am looking at developing an application that requires manipulation of a 3D graphics image by inputting numbers from text boxes or spin controls. The modifiable points on the complex object are at set areas, whereas the rest of the object must then expand and contract to a graduated fill with the changes. For instance, if I change set point X to 24 then X + 1 will be 23.5, X + 2 will be 23, etc.<br>I understand that vector images are composed of a number polygons - the more polygons the smoother the image outlines. To do the math for the polygon changes seems like a real chore. I don't want to create another autoCAD program. The image will also have a textures laid on top of the polygonal image.<br><br>I have glanced at the following:<br>- DirectX (DirectDraw) (looks like you have to learn C? akkk!)<br>- Direct manipulation of the graphics in VB6 (holy carp!)<br>- ActiveX manipulation of AutoCAD 2000 files (unsure of availability of interactive viewer for AutoCAD?)<br>- ActiveX manipulation of Visio 2000 files (unsure of availability of interactive viewer for Visio?)<br><br>Does any one have ideas as to the best tool for graphics manipulation using/working with VB6? possibly an OCX or ActiveX tool already written?<br><br>thanks for the thoughts<br>
