Object rendering method and computer-readable medium

A rendering method for causing a computer to render, on a display screen, an image of an object placed in a virtual space, the image being captured by a virtual camera placed in the virtual space, comprising:

• forming a manipulator on the display screen, a shape of the manipulator on the display screen changing in accordance with a relative position and/or orientation of the virtual camera and the object, the manipulator receiving an instruction onto the display screen from an operator to rotate the object about an axis with reference to a contour of the manipulator displayed on the display screen;
• setting a prescribed point defined on the display screen or a prescribed point present at a position at which a point defined in the virtual space is projected onto the display screen via the virtual camera;
• changing, in a case where on the display screen, among parts of the contour, a part of the contour which is displayed on the display screen to be present on a side closer to the virtual camera has come close to the prescribed point, a position of the prescribed point in a direction away from the part of the contour of the manipulator;
• rotating the object about the axis based on a rotational angle and a rotational direction of a vector directed from the prescribed point toward a position instructed on the display screen by the operator when the vector rotates along with a movement of the instructed position;
• and
• rendering an image of the rotated object on the display screen, the image being captured by the virtual camera.
