Abstract:
In many editing tools, especially sketch-based modeling, it is important to have real-time feedback to help improve the editing quality. This importance is emphasized particularly in sketch-based terrain modeling, being able to see the terrain morphing at the same time the drawing edition occurs constitutes a great user experience (see Figure 1(a)). In this work, we propose a real-time terrain modeling tool by combining a fast GPU-based terrain solver [Hnaidi et al. 2010] with a lightweight CPU-based data structure. Our tool is capable of dynamically generate multi-resolution heightmaps, enabling it to tessellate different parts of the terrain at different resolutions.
