Too slow loading and moving of 3D-model

If loading of three-dimensional model is very slow (one percent per minute) it is necessary to check up technical characteristics of the computer and settings of three-dimensional model.

For normal work with a three-dimensional graphics it is necessary to consider the following technical characteristics:

- you can not work with integrated video card, no matter how good were the other settings of the computer. In such mode full emulation of 3D-functions of video card with CPU usage is made. The modern gaming video card is recommended for use, for example: on the basis of chip GeForce GT730 and older; RADEON R7 240 and over.

- you must have a sufficient amount of RAM (8GB or more);

- you need fast access to the disk memory and its sufficient amount.

The optimal settings of 3D model are also very important for work acceleration. At work's slowing it is necessary to take following measures:

- In the main menu  of "Navigator 3D" to choose Options - Motion and to increase the Angle step of turning of model and Motion speed over model.

- to simplify the models having the point signs: to reduce the number of surfaces, textures; to reduce the size of textures. This is particularly applicable to models downloaded from third-party formats. They are usually made too detailed, inappropriate to scale of displaying a 3D-map;

- to apply a variety of views of 3D models of the same type of object for nearest, middle and far view (distance) from the observer. Models of middle and far view should have the simplified view in comparison with model of a nearest view;

- to reduce the number of objects having a 3D-view. Some linear objects can be displayed in the form of flat objects on a substrate of three-dimensional model. For this purpose on the main toolbar of "Navigator 3D" you must choose the button "Composition of the display 3D-model" and to customize the model of composition for displaying 3D-objects.
