abstract = "Motivated by the importance of having real-time feedback in
sketch-based modeling tools, we present a framework for terrain
edition capable of generating and displaying complex and
high-resolution terrains. Our system is efficient and fast enough
to allow the user to see the terrain morphing at the same time the
drawing editing occurs. We have two types of editing interactions:
the user can draw strokes creating elevations and crevices; and
previous strokes can be interactively moved to different regions
of the terrain. One interesting feature of our tool is that
terrain primitives can be interactively manipulated similarly to
primitives in vector-graphics tools. We achieve real-time
performance in both modeling and rendering using a hybrid CPU--GPU
coupled solution. We maintain a coarse version of the terrain
geometry in the CPU by using a quadtree, while a fine version is
produced in the GPU using tessellation shaders. .",
