void GraphicsCore::UpdateObjectValues(Object3D object)
{
vec3 up(0.0f, 1.0f, 0.0f);
mat4 Projection = glm::perspective(fov, float(windowWidth) / (float)windowHeight, 0.1f, 200.f);
mat4 Model = glm::translate(object.GetWorldPos());
mat4 viewMatrix = mCam.GetRotationMatrix() * glm::lookAt(mEye, mTarget, up);
mat4 ModelView = viewMatrix * Model;
mat4 MVP = Projection * ModelView;
mat3 normalMatrix = glm::transpose(glm::inverse(mat3(ModelView)));
uint shaderProgHandle = object.GetShaderID();
uint location = glGetUniformLocation(shaderProgHandle, "NormalMatrix"); //gets the UniformLocation from shader.vertex
