Drawing the object

Now that we have completed the prerequisites, let's draw a triangle:

1. In source.cpp, include Camera.h and ObjectRenderer.h:

#define GLFW_INCLUDE_VULKAN 
#include<GLFW/glfw3.h> 
 
#include "VulkanContext.h" 
 
#include "Camera.h" 
#include "ObjectRenderer.h" 

2. In the main function, after initializing VulkanContext, create a new camera and an object to render, as follows:

int main() { 
 
   glfwInit(); 
 
   glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API); 
   glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE); 
 
   GLFWwindow* window = glfwCreateWindow(1280, 720, 
                        "HELLO VULKAN ", nullptr, nullptr); 
 
   VulkanContext::getInstance()->initVulkan(window); 
 
   Camera camera; 
   camera.init(45.0f, 1280.0f, 720.0f, 0.1f, 10000.0f); 
   camera.setCameraPosition(glm::vec3(0.0f, 0.0f, 4.0f));
