TLM microstructure for GPU point rasterization point size odd-even configuration vertex coordinate mapping

The invention relates to a TLM microstructure for GPU point rasterization point size odd-even configuration vertex coordinate mapping, which comprises: a point coordinate acquisition unit used for acquiring point coordinates of point primitives; a slice element coordinate conversion unit which is used for converting the point coordinates into slice element coordinates by utilizing a first preset algorithm when judging that the point rasterization anti-aliasing is not started; a rasterization scanning range determination unit which is used for determining a rasterization scanning range according to the point sizes of the point primitives, the odd-even attributes of the point sizes and the slice element coordinates; and an effective slice element lightening unit which is used for lighteningthe pixel values of the effective slice elements according to the number and positions of the effective slice elements in the slice element region of the rasterization scanning range. According to theTML microstructure, the p
