Rendering device, rendering method, 3D model generating method, neural network model generating method, and non-transitory computer readable medium

A method for generating projection data in a 2D space comprising:

• acquiring, by at least one processor, information about the projection data in the 2D space from information about a 3D model;
• storing, by the at least one processor in at least one memory, (i) the information about the projection data in the 2D space and (ii) information associating identification information given to a part of the 3D model with a pixel where the part of the 3D model is projected in the 2D space;
• and
• generating, by the at least one processor, the projection data in the 2D space based on the information about the projection data in the 2D space.

A non-transitory computer readable medium storing therein a program which, when executed by at least one processor performs a method comprising:

• acquiring, by at least one processor, information about projection data in a 2D space from information about a 3D model;
• storing, by the at least one processor in at least one memory, (i) the information about the projection data in the 2D space and (ii) information associating identification information given to a part of the 3D model with a pixel where the part of the 3D model is projected in the 2D space;
• and
• generating, by the at least one processor, the projection data in the 2D space based on the information about the projection data in the 2D space.
