PostProcessStageSampleMode() Scene/PostProcessStageSampleMode.js 9 Determines how input texture to a PostProcessStage is sampled. Members staticconstantCesium.PostProcessStageSampleMode.LINEAR : Number Scene/PostProcessStageSampleMode.js 23 Samples the texture through bi-linear interpolation of the four nearest texels. staticconstantCesium.PostProcessStageSampleMode.NEAREST : Number Scene/PostProcessStageSampleMode.js 16 Samples the texture by returning the closest texel.
