Photo, parameters

Tool(s): Photo

Light 1, Light 2

Intensity (0-100)

Enter a value between 0 and 100 here.

The intensity refers to the number of shades of color used. If you enter 10, all 10 shades of the basic color are used. This makes the image darker.

Light source..., Light target...

To enter light source and light target, either click in the workspace or enter the X, Y, and Z coordinates in the dialog line.

Tip: It is usual to position the light source in several different viewports showing different projections. Define the position of the light in plan view and the approximate height in elevation view. When you have approximately found the correct position, you can enter the resulting coordinates at the keyboard in a further operation if necessary.

(A) Plan
(B) Elevation
(C) Active viewport, perspective view

Parallel light, Point light

You can switch between parallel and point light here.

If you choose parallel light mode, the position of the light source and target only define the direction of the light rays. The rays themselves are imagined to emanate from infinity and illuminate all 3D solids.

If you choose point light mode, only the position of the light source is of importance; point light is diffused evenly from a single light source. The individual surfaces are illuminated by this light source according to the resulting angle of incidence.

Match position of sun

Click Match position of sun if you want to simulate sunlight instead of Light 1 .

Note: Use Surroundings to define the location, date, position of north and the position of the sun.

Fill-in light

Intensity (0-100)

This light brightens shadows and surfaces. If the intensity is set to 0, then this light source is ignored.

Note: The fill-in light is always located in the eye point.

Horizon

Inclination in degrees

If you enter a positive number, all the visible elements are rotated clockwise and perpendicular to the surface of the screen. The program proposes a default value of zero degrees for the inclination of the horizon. If you imagine the screen as the lens of a camera, changing the angle of the horizon is equivalent to tilting the camera.

Example

Output

Output to destination drawing file

This is where you specify whether the photo is to be saved in the drawing file (as vector graphics).

Note: Depending on the Photo settings, the program creates up to two drawing files per photo when you save the calculation: one drawing file with the fills and one with the edges.

Output to viewport

This option is only available when the "Output to destination drawing file" is active. When you select this check box, the result of the calculation is displayed in a separate window.
