How to use image-based modeling techniques

Tutorial 2 describes the possibilities of the image-based modeling provided by Artist3D. “Assistance-commentary for operational elements” acquaints you with the meaning of each operational element.

The following text provides advice for image-based modeling of complex scenes.
The automatic definition of camera parameters and object proportions bases on the selection of box objects of one or more images using the orthogonality as well as the parallelism features of boxes. Defining the perspective is precondition before Artist3D allows adding further geometrical objects (e. g. rotational solids as an imperial roof)

Figure 1: Box objects supporting the definition of camera parameters.

Images often do not provide enough identifiable box shaped objects. Positioning boxes into images will be possible even if objects are able to be mapped on parts of a box (e. g. vertices or parallel edges). (See red objects in figure 1). De-activate non-fitting edges (by selecting the particular edge). Continue the procedure to bring each object edge in congruence with the image. After, hide the boxes with the visibility button.

Figure 2: Retrospectively hidden box objects (red). Prism object (yellow)

After hiding boxes Artist3D allows positioning other objects (e. g. prism or roof objects) into the scene without re-calculating the perspective (see figure 3). The invisible and savable boxes have continuing influence to the definition of the perspective. Export of invisible boxes is not provided to avoid misfits in the final result.

As a last step texturize new objects as provided in tutorial 2.
