Various systems and methods disclosed herein are directed to rendering point-based graphics on a computing device with the spaces between points filled in with color to produce the appearance of surfaces without gaps or holes. According to one method, one or more rasterization passes are performed on an image space. One or more filling passes are performed on the pixels in the image space in which the spaces between the pixels are filled with color to form a contiguous surface in a new image plane. One or more blending passes are performed on the image space after the filling passes, in which wherein the color of a group of pixels is a blended together. A new image space is rendered from the image space in the image buffer.
