ABSTRACT: 
The authors have developed so called *Geo-Simulator" which projects 2D GIS data such as contour map, digital orthophoto and land 
use map onto a 3D solid model made from DEM. Geo-Simulator will represent a real 3D imagery with much better 3D model as 
compared with so called bird's eye view which project 3D model onto 2D screen or monitor. The authors tried to apply this Geo- 
Simulator to a human face for the purpose of making up using computer art and morphing technology. The 3D model of the human 
face was given with photogrammetric method by Swiss Federal Institute of Technology (ETH). The result showed high capability 
and feasibility of computer aided making up with use of geo-simulator. 
INTRODUCTION: 
A real 3D solid model with a projected image is much better than 3D perspective which is displayed onto 2D computer monitor. A 
LCD projector can project a 2D image onto a 3D solid model of which impression will be more realistic. 3D solid model can be 
produced by a numerical control machine using Digital Surface Model which is usually measured with photogrmmetric method. The 
original image of a human face before making up will be artificially “making up” and “animated” with the eyes opening and closing 
with the help of a computer artist. The animation was based on a morphing technique with 13 different scenes. 
1. 3D FACE MODEL 
Five pictures of a woman’s face were taken with five CCD 
cameras and two random pattern projectors for photgrammetric 
measurement which was implemented by Nicola D’apuzzo, 
ETH, Switzerland. The DSM of a Japanese woman's face was 
given with the accuracy of 0.3 mm. 
Hokkaido Chizu Company (HCC) produced a 3D solid model 
of plastic board using a numerical control machine (NC) with 
the accuracy of 1mm. The production time was around 40 
minutes.

2. GEOMETRIC PROBLEM OF LCD PROJECTOR 
  
A LCD projector is based on central projection, while 3D solid 
  
  
frame grabs 2 | model is based on orthogonal projection. Therefore the 
T | 1 projected image onto a 3D solid model will generate somewhat 
| s | displacements depending on the projected angle. As the authors 
.] iege! 
M found that less than 2-3mm displacement has no negative 
influence, the distance between a LCD projector and 3D solid 
Fig.1, Setup of CCD Cameras and Projection model is required more than 3 meters.
