14. Tools to fire up a 3D Area!
• Set the desired area
– Viewport3D
• Light the area with a DirectionalLight!
– new ModelVisual3D
{
Content = new DirectionalLight
{
Color = Colors.White,
Direction = new Vector3D(0, 0, -1)
}
});
• Set a camera to look around!
– PerspectiveCamera
20. So, Let’s start!
• Set the desired area
• Light the area with a DirectionalLight!
• Set a camera to look around!
• Draw whatever u want!
