czm_getLambertDiffuse
Calculates the intensity of diffusely reflected light.
Parameters:
| Name | Type | Description |
|---|---|---|
lightDirectionEC |
vec3 | Unit vector pointing to the light source in eye coordinates. |
normalEC |
vec3 | The surface normal in eye coordinates. |
Returns:
float
The intensity of the diffuse reflection.
Example
float diffuseIntensity = czm_getLambertDiffuse(lightDirectionEC, normalEC); float specularIntensity = czm_getSpecular(lightDirectionEC, toEyeEC, normalEC, 200); vec3 color = (diffuseColor * diffuseIntensity) + (specularColor * specularIntensity);
