在Helix Toolkit中,相机用于控制场景的视角和视野范围,而渲染器用于将场景中的3D对象呈现在屏幕上。
以下是如何使用相机和渲染器的简单示例:
Viewport3D viewport = new Viewport3D();
PerspectiveCamera camera = new PerspectiveCamera();
camera.Position = new Point3D(0, 0, 5);
camera.LookDirection = new Vector3D(0, 0, -1);
camera.UpDirection = new Vector3D(0, 1, 0);
viewport.Camera = camera;
Model3DGroup modelGroup = new Model3DGroup();
// 添加3D模型到modelGroup中
ModelVisual3D modelVisual = new ModelVisual3D();
modelVisual.Content = modelGroup;
viewport.Children.Add(modelVisual);
HelixViewport3D helixViewport = new HelixViewport3D();
helixViewport.Children.Add(viewport);
MainWindow.Content = helixViewport;
通过这些步骤,您可以创建一个基本的3D场景,并在屏幕上呈现出来。您还可以进一步探索Helix Toolkit的各种功能和属性,以实现更复杂的3D场景和交互。
