The basics for a 3D program

3D programming is the same as 2D programming but there are a few things you need to know before starting, 3D images are displayed in Frames per second, you need to set up a camera object to view the frames then render the frames so the Camera can see them.

• The Camera is like your eyes in the rendered frames.
• Only 3D objects can be used in 3D mode, no 2D objects like Sprites are allowed
• Most other programming elements are the same as 2D programming except in 3D programming you have 3 coordinates to a point instead of 2. Example :
• X,Y,Z X = Horizontal, Y = Vertical and Z = Depth

A basic 3D program looks like this:

Program Simple3DExample

      Method Main()

            // Hide the Phrogram tool bar

            HideToolbar()

            // Switch Phrogram to 3D mode, 3D Sprites are not available

// in this mode, only model3D and SkyBoxs3D are.

            SwitchTo3D()

            // define a camera object to view the frames

            Define cam As Camera

            // define a SkyBox3D object, this object is the container

// that all models will be displayed and moved in

            Define sky As Skybox3D

            // load the mesh file that is the SkyBox

            sky.LoadMesh( "Skybox1a.x" )

            // Start the main render loop

            While Not IsKeyDown( Escape )

                  // Point the Camera object at the 3dPoint you wish to

// view

                  cam.PointAt(0,0,0)

                  // Render the image so the camera can see it

                  RenderFrame()

            End While

      End Method

End Program

This Example only displays a Skybox, you can add models and keyboard control very easily, to see how open Alen3D.kpl in the Phrogram Examples.
