1. A video processing method for performing intra prediction on a video block comprising a plurality of samples from a bitstream, comprising:
receiving reconstructed samples from a video frame in the bitstream comprising the video block;
determining reference samples in neighboring video blocks of the video block according to a first slant line and a second slant line through a sample of the video block, wherein the first slant line is along an interpolation direction and the second slant line is perpendicular to the first slant line; and
interpolating the sample of the video block based on the reference samples.
