Abstract
A virtual camera and lens system in a three dimensional computer graphic modeling environment is set using a nominal focal length and a focus distance. A true focal length is calculated. An optical axis object that represents the optical axis of the virtual camera and lens system is created in the three dimensional computer graphic modeling environment. An object is attached to the optical axis at a location that visualizes the setting of the virtual camera and lens system as determined from the true focal length. The focal length of the virtual camera and lens system is set to the calculated true focal length. The focus distance and f-stop may be determined from near and far focus points.
Claims17
A method for visualizing a setting of a virtual camera and lens system in a three dimensional computer graphic modeling environment, the method comprising:
- receiving a nominal focal length and a focus distance;
- determining a true focal length;
- providing an optical axis object that represents the optical axis of the virtual camera and lens system in the three dimensional computer graphic modeling environment;
- and
- attaching an object to the optical axis at a location that visualizes the setting of the virtual camera and lens system as determined from the true focal length.
The method of claim 9 further comprising setting FinFf to Inf if Ff is greater than a hyperfocal focus (Hf).
A method for setting of a virtual camera and lens system in a three dimensional computer graphic modeling environment, the method comprising:
- receiving a nominal focal length and a focus distance;
- determining a true focal length;
- setting a focal length of the virtual camera and lens system to the true focal length.
A method for setting of a virtual camera and lens system in a three dimensional computer graphic modeling environment, the method comprising:
- receiving a nominal focal length (FL), a desired circle of confusion (Coc), a near focus (Nf), and a far focus (Ff);
- setting a focus distance (Fo) and an f-stop (fs) of the virtual camera and lens system based on the nominal focal length (FL), the desired circle of confusion (Coc), the near focus (Nf), and the far focus (Ff).
