Abstract

Inspired by real-world point-based art forms such as Impressionism, embroidery, and pebble mosaics, we have discovered the creative potential of arranging points with distinct appearances within a unified form of expression. We propose an approach that facilitates the creation of non-uniform, art-directed representations for point-based geometry, allowing for interactive rendering in 3D space. Rather than replacing all points with a set of static image textures as input, a dynamic representation of points must be designed in a controllable way that enhances visual richness and creative freedom to the artist. We met this challenge by defining each point as multi-dimensional spatial data and replacing it with parameterized textured proxy geometry, resulting in varied painterly strokes. Notably, the textured proxy geometry remains interactive, empowering artists to dynamically modify the strokes after placement. To aid the creative process, we introduce a sketch-based authoring tool that allows artists to compose various styles by sketching a few curves in 3D space. We provide examples generated by our prototype in an oil pastel painting style to demonstrate its ability to create non-uniform stylizations for point-based geometry.
