This page provides information about the Dome Light  in V-Ray for Grasshopper.

 

Overview

The V-Ray Dome Light component creates a light shining inward at the scene as if from a spherical or hemispherical light source outside the scene extents. This light is frequently used for Image-Based lighting using panoramic HDR images as environments.

 

 

Input Parameters

On (Boolean) – Enables or disables the light source.

Invisible (Boolean) – Controls the light source visibility. Does not affect its illuminance.

Texture (AColorTex) – Specifies the color or the texture of the light. A high dynamic range texture can be used.

Intensity (Number) – Light source intensity. Calculated in Default (Scalar) units.

Shape (Integer) – Controls whether the Dome light covers the entire scene or only the half above the horizon line.

Base Plane (Plane) – Controls the orientation of the dome light defining the equatorial plane of the imaginary shape encompassing the entire model. The texture mapping will  match this plane as well. The X and Z axes the texture UV coordinate system.

 

Output Parameters

Add Light (Generic Data) – Light output that can be connected to a Renderer.

 

 

Examples

Rotation

In Grasshopper the Dome light can be rotated by rotating its Base plane component.

 

Rotation = 0 Degrees

 

Rotation = 175 Degrees
