This function updates a surface after it has been modified. This will update the binormals and tangents, update the AABB, and create a new shape for picking.

Syntax

• void Update(bool force=false)

Parameters

• force: if set to true everything will be updated, otherwise only required updates will be made.

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->SetRotation(35, 0, 0);
        camera->Move(0, 0, -3);
        Light* light = DirectionalLight::Create();
        light->SetRotation(35, 35, 0);

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

        Surface* surface = model->AddSurface();
        surface->AddVertex(-0.5, -0.5, 0, 0, 0, -1);
        surface->AddVertex(0.5, -0.5, 0, 0, 0, -1);
        surface->AddVertex(0.5, 0.5, 0, 0, 0, -1);
        surface->AddVertex(-0.5, 0.5, 0, 0, 0, -1);
        surface->AddTriangle(2, 1, 0);
        surface->AddTriangle(0, 3, 2);
        surface->Update();
        model->UpdateAABB(Entity::LocalAABB | Entity::GlobalAABB);

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

                Leadwerks::Time::Update();
                world->Update();
                world->Render();
                context->Sync();
        }
        return 0;
