| summary |
The lack of computer systems that can be easily used during the early stages of the architectural design process has been discussed for many years. The usual argument starts with the recognition that hand drawn sketches are an important tool in the early stage of both professional and student design because they can be used to visualise the designer’s ideas quickly and have the flexibility to handle any shape the designer imagines. Research has then mostly focused on using computer based sketch recognition to directly produce three dimensional models from hand drawn sketches. However sketch recognition still has certain problems that require the drawing action of users to be constrained in some way in order to be solved. If sketch recognition is still imperfect, the possibility of directly sketching within digital 3D space should be considered. Some systems allowing user to sketch in digital 3D space have been developed which do not depend on sketch recognition. Although Piranesi does not aim to support sketch design, it does allow the user to paint in the Z-buffer space - an unique idea termed "interactive rendering." SketchVRML tries to generate 3D geometrical data automatically from 2D hand drawn sketches by adding the depth value to the drawn lines according to the strength of line strokes. SketchBoX provides translucent surfaces in digital 3D space which can be glued onto existing objects or arranged anywhere in space. These surfaces have texture map data which can be modified by painting onto the texture. Transparent textures can be painted onto the surfaces to create see-through portions. Moderato also uses this technique to model a polygonÕs shape. |
