PostProcessStageSampleMode() Scene/PostProcessStageSampleMode.js 6 Determines how input texture to a PostProcessStage is sampled. Members staticconstantCesium.PostProcessStageSampleMode.LINEAR : Number Scene/PostProcessStageSampleMode.js 20 Samples the texture through bi-linear interpolation of the four nearest texels. staticconstantCesium.PostProcessStageSampleMode.NEAREST : Number Scene/PostProcessStageSampleMode.js 13 Samples the texture by returning the closest texel.
