Abstract

The visual quality of urban space determines the pleasant degree of human's mind that evoked by the vision. Therefore, visual thinking of space is significant in the urban design process. In 3D dynamic virtual environment, through the visibility computation, the "true" visual analysis can be carried out, which makes the design process more visual and scientific. The first critical issue of visual analysis is the construction of the visual analysis model. The visual analysis concept model and the analysis criterion come from the urban design result. The design result and quantify criteria of urban space could be embedded into the 3D analysis models, and then the visual effect can be evaluated through the visual analysis. The height of impressible area, the back-off distance of the street building, or the open space detail can be effectively controlled and analyzed. The second is the proper presentation. The visible field with certain eye-level and certain view-angle can be computed, but it is not equal to what can be seen. The visual analysis based on the 3DCM facilitates planners and designers to consider the multi-dimensional urban space during the design process.
