1. A simulation apparatus comprising:
- a camera parameter generating means that generates a camera parameter for a three-dimensional computer graphic, on the basis of sensor specification information regarding measurement by a sensor, and a sensor position and posture parameter indicating a position and posture of the sensor;
a graphics board having a depth buffer that stores a depth value of every polygon represented by three-dimensional polygon data, calculating the depth value of each polygon on the basis of the camera parameter and the three-dimensional polygon data, and sequentially updating the depth value within the depth buffer with the calculated depth value; and
a sensor data output means that converts the depth value into sensor data and outputs the converted data.

Abstract
To realize high speed simulation a simulation apparatus is provided with a graphics board including a depth buffer that stores a depth value of each polygon represented by three dimensional polygon data. In the graphics board, the depth value of each polygon is calculated on the basis of a camera parameter and the three dimensional polygon data, and the depth value within the depth buffer is sequentially updated with the calculated depth value. According to the depth value, sensor data is generated and outputted.
