This function transforms a position in global space onto a position in screen space.

Syntax

• Vec3 Project(const Vec3& position)

Parameters

• position: the position in global space to transform.

Returns

Returns a position in screen space. The X and Y components correspond to 2D screen coordinates, while the Z component contains the foreward distance to the projected point.

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, -8);
    Light* light = DirectionalLight::Create();
    light->SetRotation(35, 35, 0);
    camera->SetProjectionMode(2);
    camera->SetZoom(50);

    //Create a model
    Model* model = Model::Box();
    model->SetColor(0.0, 0.0, 1.0);
    model->SetRotation(0, -90, 0);
    
    while (true)
    {
        if (window->Closed() || window->KeyDown(Key::Escape)) break;

        //Make the model move in a circle
        model->Turn(0, Leadwerks::Time::GetSpeed()*0.5, 0);
        model->Move(0, 0, 0.1);

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

        Vec3 p = camera->Project(model->GetPosition());

        std::string text = "This is a box!";
        Font* font = context->GetFont();
        p.x -= font->GetTextWidth(text) / 2;
        p.y -= font->GetHeight() / 2;

        context->SetBlendMode(Blend::Alpha);
        context->DrawText(text, p.x, p.y);

        context->Sync();
    }
