Configure 3D

Sets the system based settings for the 3D View. These settings are machine based and will take effect immediately, unless otherwise advised by the software, and apply for every SEE project.

The Configure/3D command is selected from the Utilities task.

3D Configuration dialog box

Item	Used to
Driver	Select the 3D graphical engine driver that the 3D View will use to display. The options are OpenGL, WinGDI or Direct3D. The best choice of setting depends upon the graphics card installed. Some graphics cards perform best with OpenGL, some with Direct3D. WinGDI will normally be the slowest setting in terms of performance, but should provide basic functionality on any functioning Windows GDI compatible device. If Direct3D is selected it requires that DirectX 9.0c (4.09.0000.0409) or higher be installed on the machine. If OpenGL is selected it required that OpenGL 1.1 or higher be installed on the machine. Some changes to the driver may require the user to restart LISCAD for the change to take effect. If this is the case, a message warning the user of this will be displayed.
Disable Hardware Acceleration	Select this option if you do not want Hardware Acceleration to be employed. Normally Hardware Acceleration will speed up performance and is useful, depending upon the card. Not available with the WinGDI driver.
Use Anti-Aliasing	Anti-aliasing is the technique of minimizing jagged or blocky patterns and could improve the rendering of images and textures. Not available with the WinGDI driver.
Image Rendering Performance	The user can use the slider to decrease the time taken to display a background image overlaid over a terrain model in the 3D View, but with the drawback of decreased resolution or vice versa, increase the time taken but have increased resolution. This setting only applies to Background Image display overlaid over a terrain model, not Textures display.
Walk Camera Height	The user can specify a height above the terrain where the Walk Camera will be positioned.
Fly Camera Aeroplane Control	If this is checked, when the user operates the Fly Camera, moving the mouse pointer down the screen whilst holding the left button down will cause the camera to look upwards, effectively like a pilot operating the plane's joystick. If it is not checked, the camera will look downwards when the mouse pointer is moved down the screen with the left mouse button down.
Point Cloud Scan Point Size	Set the size of scan points displayed in the Point Clouds. The effect of this feature is that the scan points increase in screen size as you zoom in, thereby maintaining better image definition and screen colouration as the scan points separate. For particular scans or parts of scans, altering this value may further assist the viewing clarity of the scanned features. The default (10) represents approximately 10mm at real world sizes.
OK	Save any change made and close the dialog box.
Cancel	Close the dialog box leaving the settings unchanged.
