![]() ![]() Please note that all operations with elevations are performed in the 2D mode only. swimming pools, while the Pit Poly tool is used for creating more advanced shapes. The Pit Rect tool is great for creating rectangular pits, e.g. The negative numbers entered into the Elevation Point field create the lowest underground point. Mark the top point with the help of the Elevation Point and underground parts using the Pit Rect and Pit Poly tools. More information on working with the elevation lines and splines: for Mac, for iPhone/ iPad, and for Windows. For straight lines, use the Elevation Line tool, while the Elevation Spline tool resembles a freehand tool in graphics software and creates a curved line. Quadratic = 0.80 Directional Light SettingsĪ light source of the Spot type lets you set up additional parameters of the beam of light: Angle and Falloff.Repeat the terrain elevations using the “Elevation Line” or “Elevation Spline” tools. Quadratic increased (light fades quicker than above): The images below demonstrate how parameters affect the 3D scene. Tip: adjust the Light Attenuation parameters when the Luminosity slider is in the middle. It does the same as the Luminosity control in the Light Properties tab of the Inspector. The Luminosity parameter changes the common luminosity of a light source. D – the distance from the light source to a point in the 3D space (when the program is calculating light for this point). The parameters are used by the rendering engine for calculating the attenuation factor:Īf – Attenuation factor Kc – Constant (always 0.5) Kl – Linear Kq – Quadratic. The Light Attenuation parameters Linear and Quadratic control how quickly the light fades out depending on the distance from a point in the 3D space to the light source. The zero point is shown in the preview as colored axes. The location is calculated as a distance to the zero point of the coordinate system of the lamp. To move a light source to another location, use the Position controls. This option can be useful for switching off all of the light sources except for the one that you are adjusting. This is the same option that can be found in the Light Properties tab of the Inspector. The size of the glow can be adjusted by the Glow Size slide bar.ģ - The On/Off switch turns the light on or off. To remove the selected light source, use the minus button.Ī light source has the following properties:ġ - The Type can be set to Point (omni-directional light) or Spot (directional light).Ģ - The Glow can be selected from a popup list. To add a light source, click the plus button below the list. To select and adjust one, click on it in the list. Light Source ListĪ lamp can have several light sources. To preview a lamp with a different intensity of the ambient light, use the Daytime buttons. To restore the default view point and zoom, double-click on the preview. To choose a predefined view, use the buttons below the preview. To change the point of view, place the cursor over the preview box, click and drag. The colors of the axes correspond to the colors of the X, Y and Z coordinates in the Positioning section.Ħ – Reflection of the light on the floor. You can see how the light drops on the walls, floor and ceiling.ĥ – The coordinate axes of a lamp indicate the point where X=0, Y=0 and Z=0. The preview shows your lamp inside a small empty room. They define how quickly the light fades out depending on the distance from a light source. You can rotate a light source, and change the light beam properties.Ħ – The position of the current light source in relation to the lamp.ĩ – The Light Attenuation and Luminosity settings. They are activated when the current light source is of the spotlight type. Main Elements of the Light Source Editorġ – Choose one of the predefined points of view.ģ – Choose daytime to preview a lamp with different lighting conditions.Ĥ – Spotlight controls. One lamp can have one or more light sources. The term "light source" will be used for a part of a 3D model that simulates a single light source and is actually a source of light in the 3D scene. The term "lamp" will be used in this section for any object that emits light (lamp, candle, fireplace, and so on). The functionality described in this section is only available in the Pro edition. ![]() To open the editor, right-click on an object in your project and select Edit Light Sources… Live Home 3D lets you create and edit light sources. ![]()
