| Abstract: | Based on the measurement along axes a function set of axonometric projection is established and extended. Various parameters of the projection were analysed. With the coefficient matrix of the function set, the formula for calcuaxes and the amplification factor is established. The relationship between the direction of projection and the spatial rectangular Cartesian coordinate system and the relationship between the direction of projection and the plane of projection are made clear. The conditions of a normal and an oblique axonometrie projection are distinguished. The problems concerning the judgment of parameters and the nature of axonmetric projection are solved. |
