This functions sets a camera to render directly to a texture. The texture can be used in a material and applied to an object, or drawn onscreen. You can use this feature for making CCTV systems, rear-view mirrors, or other visual effects.

Syntax

• SetRenderTarget(Texture* target)

Parameters

• target: the texture to render to. If this is NULLthe camera will render to the current buffer or context.

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, -6);

        Camera* camera2 = Camera::Create();
        camera2->Move(0, 0, -4);
        camera2->SetClearColor(1, 0, 0);
        Entity* pivot = Pivot::Create();
        camera2->SetParent(pivot);

        Texture* tex = Texture::Create(512, 512);
        Material* mtl = Material::Create();
        mtl->SetShader("Shaders/Model/Diffuse.shader");
        mtl->SetTexture(tex);
        camera2->SetRenderTarget(tex);

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

        Model* model = Model::Box();
        model->SetPosition(-2, 0, 0);
        model->SetMaterial(mtl);

        model = Model::Cylinder();

        model = Model::Cone();
        model->SetColor(0.0, 0.0, 1.0);
        model->SetPosition(2, 0, 0);

        while (true)
        {
                pivot->Turn(0, 0.5, 0);
                if (window->Closed() || window->KeyHit(Key::Escape)) break;

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