How to do Ortho projection properly?. With perspective projection everything works well but with ortho projection nothing visible on screen.

The screenshot with perspective projection :

The screenshot with ortho projection :

The screenshot of MeshViewer on Renderdoc with ortho projection :

The code of view projection matrices :

mViewMatrix = glm::lookAt(mPositionVector, mPositionVector + mFrontVector, mUpVector);
mProjectionMatrix = glm::ortho(0.0f, 1280.0f, 0.0f, 720.0f, 0.1f, 1000.0f);

I’ll give more detail when needed.
Thank.

Update : After bit of relearning projection I found the solution by changine to :

mProjectionMatrix = glm::ortho(0.0f, 1.0f, 1.0f, 0.0f, 0.1f, 1000.0f);

Sorry for wasting your time.
