We present VecFusion, a new neural architecture that can generate vector
fonts with varying topological structures and precise control point positions.
Our approach is a cascaded diffusion model which consists of a raster diffusion
model followed by a vector diffusion model. The raster model generates
low-resolution, rasterized fonts with auxiliary control point information,
capturing the global style and shape of the font, while the vector model
synthesizes vector fonts conditioned on the low-resolution raster fonts from
the first stage. To synthesize long and complex curves, our vector diffusion
model uses a transformer architecture and a novel vector representation that
enables the modeling of diverse vector geometry and the precise prediction of
control points. Our experiments show that, in contrast to previous generative
models for vector graphics, our new cascaded vector diffusion model generates
higher quality vector fonts, with complex structures and diverse styles.

我们提出了 VecFusion，这是一种新的神经架构，可以生成具有不同拓扑结构和精确控制点位置的矢量字体。通过级联扩散模型，我们的方法包括一个光栅扩散模型和一个矢量扩散模型。实验表明，与以前的矢量图形生成模型相比，我们的新的级联矢量扩散模型能够生成更高质量、具有复杂结构和多样化样式的矢量字体。
