How do I show multiple camera views on the screen by dividing up the screen? I would like to show multiple perspectives of the same object/scene.

As always:
- A code snippet would be nice
- Please check back if you post if I have question.


Thanks Much

Check the help for dbSetCameraView(). You can use that command on any camera, including the default camera (camera zero).

I want all the 4 camera to be visible on the screen by splitting the screen up into four squares.

Speaking of this - IanM, is it possible to set the render target of a camera or something to a texture on an object? Think of, like, a security camera thing.

Edit: Durr.

Quote: "dbSetCameraToImage
This command will direct all camera output to the specified image. This command is ideal for performing the fastest method of creating textured polygons that show a different view within your 3D world. You can use this command to create mirrors, security cameras within your game or dynamically moving the camera view around on a polygon shape such as a floating panel.
"


I guess so.

int iCamera = camera's id
float fLeft = view position x on screen
float fTop = view position y on screen
float fRight = view's lower right corner's position x on screen
float fBottom = view's lower right corner's position y on screen

I think he meant the viewport of the camera.

Math...splitting a screen into 4 equal boxes is the screen dimensions(width and height) divided by 2.

By the way, if I were you, I would add this:



Makes black lines separating the panels. It just looks better.
