Example

This example creates a box brush from scratch.

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a world
    auto world = CreateWorld();

    //Create a camera    
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->Turn(35, 0, 0);

    //Create light
    auto light = CreateBoxLight(world);
    light->SetRange(-20, 20);
    light->SetArea(20, 20);
    light->SetRotation(35, 35, 0);
    light->SetColor(2);

    //Create brush
    auto brush = CreateBrush(world);
    brush->SetColor(0, 0, 1);

    //Add brush vertices
    float w = 1; float h = 1; float d = 1;
    brush->AddVertex(w * 0.5, h * 0.5, d * 0.5);

    face->AddIndice(0);
    face->AddIndice(3);
    face->AddIndice(7);
    face->AddIndice(4);

    //Finalize the brush
    brush->Build();
