Modelling Landscape Forms in Three Dimensions as a Project for Training in More Effective Perception of These Forms
(University of Oregon, 1937-07) Cantrall, Harriet M.
The purpose of this project is to show the advantage of the three dimensional approach to the perception of landscape forms by means of clay modelling. The method employed was first, to shape the models for the general proportions and size desired; second, the larger planes in their relative proportions; and finally, to add the sub-divisions and details. In the simpler models, close attention was given to acquire the technique – the clean, sharp joining of one plane cutting another – which is so important in the perception of the bulk of each of the uniting forms. When the models were completed and ready to photograph, the greatest care was taken that all edges were clean-cut and definite, and the surfaces well considered as to the form beneath. Masses were considered from all viewpoints so that the study would be in reality a three dimensional one; thus several compositions could be studied in one model. In finishing the model it is desirable to have the clay in such a state of moisture that it can be cut as one cuts a bar of soap – without disturbing the mass. Photographs must be made soon after the modelling is completed, since the edges are likely to be altered in the process of keeping wet wrappings about the models to prevent cracking of the smaller parts.
