A computerized method of for rendering a lighting effect can include receiving from a user inputs regarding the location of an object within a design space. Furthermore, the method can include receiving from the user one or more inputs regarding the location of one or more light sources within the design space. Additionally, the method can include calculating a lighting effect of the one or more lights on the object within the design space. Furthermore, the method can include rendering the lighting effect during a time interval that is independent of the number of the one or more light sources within the design space, such that rendering the lighting effect for one of the one or more light sources takes the same amount of time as rendering the lighting effect for a plurality of the light sources.
