D3PLOT 22.1
PERSPECTIVE... Setting Perspective Attributes
PERSPECTIVE... Setting Perspective Attributes
Use this option to switch on and adjust perspective settings.
D3PLOT will calculate the "bounding box" round your model and derive a default perspective distance of three times that value, which give a typical viewing angle of around 37 degrees.
Use and to adjust this, or type in a new value.
If you get extremely close to the structure you may find that the overlay of hidden and shaded plots starts to come away from the underlying elements. This is a limitation of Z-buffered hidden-surface removal and a solution is given in controlling overlay quality in 3D mode.
