问题 I am using GLScene in my delphi project. I add some freeform on my scene (for example tooth). in the past I don't use material libs.

Thanks for any answer or tip 回答1: Apparently the texture is not active. Did you enable it in the

问题 I'm writing a 3D modeling application using GLScene , so I need to move some vertices under mouse position to new position by grabbing the vertex. First of all, I load a sphere and pick up a vertex by mouse,then I try to drag it but I realize that the vertex doesn't move under mouse caret correctly. unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Math, //GLScene

I use Delphi/GLScene 回答1: If you wish for your vector to have the same direction as the camera, you can simply use the GLCamera.Direction vector property. So, e.g. if your camera is currently pointing along the x axis the Direction property will be (1,0,0). You can use this vector and simply copy these x,y,z values and assign them to your x,y,z values of your
