Abstract

Systems and methods for shading analysis and creating a 3D model of a surface of interest are provided. Such systems and methods may include taking ray traces to determine light contact with the surface of interest. Shadow maps may be generated. Power flux calculations may also be performed.

Claims

1. A system for determining shading on a surface of interest, the system comprising:

a ray trace module stored in memory and executable by the processor to take a ray trace from the sun to a plurality of points on the 3D model of the surface of interest at a plurality of times to represent multiple positions of the sun; and

a shading module stored in memory and executable by the processor to perform a shading calculation of the surface of interest based on the ray trace.

2. The system of claim 1, wherein the shading calculation is used as an input to a power flux calculation module stored in memory and executable by the processor to perform a power flux calculation for the surface of interest.

3. The system of claim 2, wherein the power flux generation calculation is used to design a solar energy system for the surface of interest.

4. The system of claim 3, wherein the solar energy system is designed algorithmically according to a set of design rules.

10. A method of calculating the power flux of a surface of interest, the method comprising:

creating a 3D model of a surface of interest, the model being created by a modeling module stored in memory and executable by a processor;

taking a ray trace with a ray trace module stored in memory and executable by the processor, the ray trace being taken from the sun to a plurality of points on the 3D model of the surface of interest at a plurality of times to represent multiple positions of the sun; and

performing a shading calculation with a shading module stored in memory and executable by the processor, the shading calculation being based on the ray trace.

11. The method of claim 10, wherein the shading calculation is used as an input to a power flux calculation module stored in memory and executable by the processor to perform a power flux calculation for the surface of interest.

12. The method of claim 11, wherein the power flux generation calculation is used to design a solar energy system for the surface of interest.

13. The method of claim 12, wherein the solar energy system is designed algorithmically according to a set of design rules.
