Verticies: Mesh 클래스의 정보를 VAO, VBO에 바인딩

VBO binding code.

Bind mesh vertices to VBO

void Vertices::WriteMeshDataToVertexBuffer(const Mesh& mesh) const noexcept
{
	char* buffer = reinterpret_cast<char*>(glMapBuffer(GL_ARRAY_BUFFER, GL_WRITE_ONLY));
	glBindBuffer(GL_ARRAY_BUFFER, VBO);
	unsigned offset = 0;

	vec2<float> point;
	Color4f color;
	vec2<float> texture;

	// binding vertices information to buffer object
	for (int i = 0; i < static_cast<int>(verticesCount); ++i)
	{
		for (VerticesDescription::Type element : layout.GetTypes())
		{
			switch (element)
			{
			case VerticesDescription::Type::Point:
				point = mesh.GetPoint(i);
				memcpy(buffer + offset, &point, sizeof(point));
				offset += sizeof(vec2<float>);
				break;
			case VerticesDescription::Type::Color:
				color = mesh.GetColor(i);
				memcpy(buffer + offset, &color, sizeof(color));
				offset += sizeof(Color4f);
				break;
			case VerticesDescription::Type::TextureCoordinate:
				texture = mesh.GetTextureCoordinate(i);
