This function reverses the triangle order and inverts the normals of the entire surface, effectively "lipping" the surface inside out.

Syntax

• void FlipNormals()

Returns

Returns the number of vertices in the surface.

Example

#include "App.h"

using namespace Leadwerks;

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

App::~App() { delete world; delete window; }

Model* model = NULL;

bool App::Start()
{
        window = Window::Create();
        context = Context::Create(window);
        world = World::Create();
        camera = Camera::Create();
        camera->SetRotation(35,0,0);
        camera->Move(0,0,-3);
        Light* light = DirectionalLight::Create();
        light->SetRotation(35,35,0);
        
        model = Model::Box();
        model->SetColor(1.0,0.0,0.0);
        Surface* surface = model->GetSurface(0);
        surface->FlipNormals();
        
        return true;
}

bool App::Loop()
{
        if (window->Closed() || window->KeyDown(Key::Escape)) return false;
        
        model->Turn(0,Leadwerks::Time::GetSpeed()*1.0,0);

        Leadwerks::Time::Update();
        world->Update();
        world->Render();
        context->Sync();
        
        return true;
}
