The picture shows two planes and two lights. How lights react to a mesh depend on values set for each mesh vertex termed normals, shown in the picture below as arrows giving the direction of the lighting normals. Example of Excluding Meshes to Light Lighting Normals Commenting out lines 26 and 27 in turn will show the individual effect. In the following example two meshes are to be excluded from light0 and twenty three from light1. The number of meshes to be excluded can be one factor in deciding which method to use. There are two ways to exclude some meshes from being lit.Ī mesh can be added to the excludedMeshes array or add the ones not to be excluded to the includedOnlyMeshes array. When a light is created all current meshes will be lit by it. You can change this number with this code: Intersecting Lights Colors Intersecting Spot Lights Limitationsīabylon.js allows you to create and register as many lights as you choose, but know that a single StandardMaterial can only handle a defined number simultaneous lights (by default this value is equal to 4 which means the first four enabled lights of the scene's lights list). White hemispheric light with a black groundColor is a useful lighting method. You can think of the diffuse and specular light as coming from the centre of the object in the given direction and the groundColor light in the opposite direction. Point Light Example Directional Light Example Spot Light Example Hemispheric Light Exampleįor a hemispheric light the groundColor is the light in the opposite direction to the one specified during creation. In these playgrounds see how the specular color (green) is combined with the diffuse color (red) to produce a yellow highlight. Specular produces a highlight color on an object.Diffuse gives the basic color to an object.Two of these diffuse and specular apply to all four types of light, the third, groundColor, only applies to an Hemispheric Light. There are three properties of lights that affect color. Vector3 ( 0, 1, 0 ), scene ) Color Properties HemisphericLight ( "HemiLight", new BABYLON. This causes direct light from the projector to reflect squarely into the viewer's field of vision while the outer contrast layer enhances image quality while absorbing indirect ambient light.Var light = new BABYLON. The angular reflective or retro reflective material incorporates a diffusion layer over a highly reflective surface. The alr projector screen is superior to traditional white or gray materials in its ability to maintain a sharp, bright image regardless of ambient light. This type is also specifically geared toward UST or ultra short throw projectors. This includes CLR® or ceiling light rejecting projector screen materials are specially designed for the presence of overhead light sources commonly encountered in residential and commercial environments. There are many ambient light rejection projector screen variants to choose from. This means that an alr screen is an ideal fit for family rooms as well as lecture halls, boardrooms, sports bars, training facilities, and other business environments. The ambient light rejecting projector screen is the perfect solution for rooms that have little or no control over incidental light. Content that was nearly unwatchable during the day was suddenly bursting with colors.” – Brian Mitchell, Īn ambient light rejecting screen negates the washout effects of ambient light while maintaining superb picture quality under normal room lighting conditions.

“It was clear within seconds, the Aeon CLR series offered tremendous improvements in daylight viewing. An LED back-lighting Kit is included for added aesthetics. The screen uses a Ceiling Light Rejection® technology.

Aeon CLR ® with StarBright CLR®offers a wide viewing angle, neutral color temperature, and enhanced picture contrast in a theater-grade image.ĮDGE FREE CLR ® means there is an internal framework with wraparound material bordered with an ultra-thin bezel. StarBright CLR® is specifically designed for ultra-short-throw projectors to provide a large-screen performance in the close quarters of most residential or even training environments. This also enables the material to provide contrast levels that are 100 times greater than that of standard matte white projection screens. Its serriform optical surface lens microstructure negates the washout effect of ambient light especially from overhead sources. The Aeon CLR® is an EDGE FREE CLR ® fixed frame screen that uses Elite Screens innovative StarBright CLR® (Ceiling Light Rejecting®) material.
