This function sets a camera's field of view (FOV). The field of view is an angle that controls how broad the visible region is on the vertical axis.

The default camera FOV is 90.0.

Syntax

• void SetFOV(float fov)

Parameters

• fov: the new field of view to set.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

int main(int argc, const char *argv[])
{
        Leadwerks::Window* window = Leadwerks::Window::Create();
        Context* context = Context::Create(window);
        World* world = World::Create();
        Camera* camera = Camera::Create();
        camera->Move(0, 0, -3);
        Light* light = DirectionalLight::Create();
        light->SetRotation(35, 35, 0);

        Model* model = Model::Box();
        model->SetColor(0.0, 0.0, 1.0);

        while (true)
        {
                if (window->Closed() || window->KeyDown(Key::Escape)) break;

                model->Turn(0, Leadwerks::Leadwerks::Time::GetSpeed(), 0);

                float deltazoom = (window->KeyDown(Key::Up) - window->KeyDown(Key::Down)) * Leadwerks::Leadwerks::Time::GetSpeed()*0.5;
                float fov = camera->GetFOV() - deltazoom;
                fov = Math::Clamp(fov, 5, 179);
                camera->SetFOV(fov);

                Leadwerks::Leadwerks::Time::Update();
                world->Update();
                world->Render();

                context->SetBlendMode(Blend::Alpha);
                context->DrawText("FOV: " + String(camera->GetFOV()), 2, 2);
                context->DrawText("Zoom: " + String(camera->GetZoom()), 2, 22);

                context->Sync();
        }
