# Class: FXUtils

### LuxModule: luxinialuacore

The FXUtils class is a collection of lua functions that aid setting up effects.

## Methods:

applyMaterialTexFilter (matobject, texture, table texoffsets, table weights, [table colorbias], [Rectangle visible])
  returns: (matcontrolid texoffsets, weights, clrbias)

  adds a texture filter material to an object that supports matobject and matsurface assignments. Texoffsets and weights should match in length and may not exceed 9. Both contain tables of sizes up to 4. Texoffsets should be passed in "pixelsize" ie {-1,-1} would be lower left neighboring pixel. Weights reflect weighting for each color channel. The resulting pixel will be the weighted sum of all contributing pixels. Rectangle or powerof2 textures are correctly dealt with and approrpriate conversions of texture coordinates are done.
  Colorbias is added at the end and be default a table of {0,0,0,0}.

  Returns matcontrolids for changing control values later, if needed.

getCubeMapCameras (int visflagstart, [spatialnode], [float frontplane], [float backplane])
  returns: (table cameras)

  returns table with 6 cameras. Each setup for dynamic cubemap rendering. Order is CubeMap sides 0-5. Local matrices are set and rotation inherition is disabled.
