Fig. 1. The analysis diagram of view resolution

When d is 10 meters and w is 24 meters, the width of the ground is about entire
62.5% of the projection screen, there is about physical pixel 3200 in the horizontal,
the texture pixel density is:

Density = 3200/w =133 . (2)

If per meter has 133 pixels, it can meet the need of driver's eyes observation. In
order to meet the need of close shot visual effect, we can take the following measures.
(1)Using high resolution ground texture: surface texture resolution of 10 meters
road is 2048 x 2048, 1 meter has 204 pixels.
(2) We use the method of diffuse texture overlay detail texture for the tank body
first armor, this method can improve the surface details and texture when observing
closely. The effect is shown in figure 2.

(3) Instead of texture description, we construct the model for body first armor plate
again, including the model of reactive armor and nut. Effect contrast is shown in
figure 3.
