Texture loading is done with:

and
tdogl::Texture (requires few additional tdogl headers)

#pragma once

Sphere class inherits from Models class. It is partly rewritten from tutorial http://in2gpu.com/opengl-3/.

#pragma once

#include <vector>

#include "../IGameObject.h"

#include <glm/glm.hpp>
#include <glm/gtc/type_ptr.hpp>

			virtual void Destroy() override;

			virtual GLuint GetVao() const override;
			virtual const std::vector<GLuint>& GetVbos() const override;

		protected:

			GLuint program;
			std::vector<GLuint> vbos;

			unsigned int verticesSize;
			tdogl::Texture* gTexture;

			static glm::mat4 projectionMatrix;
		};
	}
}

 

#include "Model.h"

using namespace Rendering;
using namespace Models;

glm::mat4 Model::projectionMatrix = glm::perspective(glm::radians(35.0f),
	800.0f / 600.0f,
	0.1f, 10.0f);

Model::Model()
{
	verticesSize = 0;
	gTexture = NULL;
}

Model::~Model()
{
	Destroy();
}

void Model::Draw()
{
	//this will be again overridden
}

void Model::Update()
{
	//this will be again overridden
}

void Model::SetProgram(GLuint program)
{
	this->program = program;
}

GLuint Model::GetVao() const
{
	return vao;
}

const std::vector<GLuint>& Model::GetVbos() const
{
	return vbos;
}

void Model::Destroy()
{
	glDeleteVertexArrays(1, &vao);
	glDeleteBuffers(vbos.size(), &vbos[0]);
	vbos.clear();
}

And IGameObject is…

#pragma once

#include <vector>
#include <iostream>

#include "..\..\packages\nupengl.core.0.0.0.1\build\native\include\GL\glew.h" 
#include "..\..\packages\nupengl.core.0.0.0.1\build\native\include\GL\freeglut.h" 

#include "VertexFormat.h"

namespace Rendering
{
	class IGameObject
	{
		public:
			virtual ~IGameObject() = 0;

			virtual void Draw() = 0;
			virtual void Update() = 0;
			virtual void SetProgram(GLuint shaderName) = 0;
			virtual void Destroy() = 0;

			virtual GLuint GetVao() const = 0;
			virtual const std::vector<GLuint>& GetVbos() const = 0;
	};

	inline IGameObject::~IGameObject()
	{//blank
	}
}

VertexFormat is defined as:

#pragma once
#include "glm\glm.hpp" //installed with NuGet

namespace Rendering
{
	struct VertexFormat
	{
		glm::vec3 position;
		glm::vec4 color;
		glm::vec2 texture;

		VertexFormat(const glm::vec3 &iPos, const glm::vec4 &iColor, const glm::vec2 &iTex)
		{
			position = iPos;
			color = iColor;
			texture = iTex;
		}
	};
}

Result

I’ve used this sphere in PA199 3D Breakout (C++/OpenGL) project.
