This function sets the projection mode of a camera.

Syntax

• void SetProjectionMode(int projectionmode)

Parameters

• projectionmode: the new field of view to set.
• Camera::Orthographic: flat 2D rendering.
• Camera::Perspective: 3D perspective rendering.

Example

#include "Leadwerks.h"

        light->SetRotation(35, 35, 0);
