Aspects of the disclosure provide methods and apparatuses of quality assessment for three dimensional (3D) graphics modeling. In some examples, an apparatus for quality assessment includes processing circuitry. The processing circuitry determines an updated virtual camera position in response to a position change of a virtual camera for projection from a three-dimensional (3D) space to a two-dimensional (2D) space. The processing circuitry projects a reference 3D representation according to the updated virtual camera position to generate a reference 2D image, and projects a 3D representation under assessment according to the updated virtual camera position to generate an assessment 2D image. The processing circuitry calculates an assessment score associated with the updated virtual camera position based on the reference 2D image and the assessment 2D image.
