High quality rendering of complex objects need very small triangles ● Building low level of details is very hard ⇒ A simpler, more efficient rendering primitive than triangles ? ●
●
Modern 3D scanning devices acquire huge point clouds (~10 million pts) generating consistent triangle meshes is time consuming and difficult ⇒ A rendering primitive for direct visualization of point clouds ? ●

= holes filling ⇒ Surfels need to
interpolate the surface between the points
Motivation of this work ●
Propose a very fast surfel rendering ●
Since GPU performance outpaces CPU, we use the capability of recent GPU
●
High quality texture filtering
