  **getWorldNormalVector()** | float3 | Normalized normal in world space, after bump mapping (must be used after `prepareMaterial()`)
  **getWorldGeometricNormalVector()** | float3 | Normalized normal in world space, before bump mapping (can be used before `prepareMaterial()`)
  **getWorldReflectedVector()** | float3 | Reflection of the view vector about the normal (must be used after `prepareMaterial()`)
  -**getNormalizedViewportCoord(float2)** | float2 | Normalized viewport position (i.e. clip-space position normalized to [0, 1], can be used before `prepareMaterial()`)
  +**getNormalizedViewportCoord()** | float2 | Normalized viewport position (i.e. clip-space position normalized to [0, 1], can be used before `prepareMaterial()`)
  **getNdotV()** | float | The result of `dot(normal, view)`, always strictly greater than 0 (must be used after `prepareMaterial()`)
  **getColor()** | float4 | Interpolated color of the fragment, if the color attribute is required
  **getUV0()** | float2 | First interpolated set of UV coordinates, only available if the uv0 attribute is required
