This function adds the contents of one surface to another. This can be used to collapse multiple surfaces into one.

Syntax

• void Add(Surface* surface, const Mat4& mat)

Parameters

• surface: the surface to add.
• mat: surface positions and normals will be transformed by this 4x4 matrix before adding.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

Model* model = NULL;

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);

        //Create  model
        Model* box = Model::Box();
        box->SetColor(0.0, 1.0, 0.0);
        Surface* surface1 = box->GetSurface(0);

        //Create a second model
        model = Model::Cylinder();
        model->SetColor(0.0, 0.0, 1.0);
        Surface* surface2 = model->GetSurface(0);

        //Add the first surface to the second one
        Mat4 mat;
        mat[3][0] = 1.5;// Offset the matrix position by 1.5 on the x axis
        surface1->Add(surface2, mat);
        model->UpdateAABB(Entity::LocalAABB | Entity::GlobalAABB);

        //Release the first model
        box->Release();

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

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

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