List of emission() Examples

Examples of emission()

ca.eandb.jmist.framework.Material.emission()
Evaluates the emission distribution function (EDF). @param x The SurfacePoint for which to compute the EDF. @param out The Vector3 indicating the outgoing directionfor which to evaluate the EDF. @param lambda The WavelengthPacket associated with thelight traveling along the path. @return The value of the EDF.
