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

Syntax

• Vec3 UnProject(const Vec3& position)

Parameters

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

Returns

Returns a position in global space.

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, 1, -3);

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

        //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;

                //UnProject mouse coordinates from screen space to world space and position the box there
                Vec3 p = window->GetMousePosition();
                p.z = 3;//distance in front of the camera to project to
                p = camera->UnProject(p);
                model->SetPosition(p);

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