“…Rendering flames at interactive frame rates has also been explored, this techniques inevitably sacrifice quality for performance. Bridault et al [3] used a spectrophotometer to capture photometric distributions of candles. The intensities are stored on a texture and changes in illumination over time are approximated with an attenuation factor proportional to the size of the flame.…”

Figure 1: Our image-based framework is able to generate realistic flames, which can be placed in a variety of scenes where they provide lifelike illumination. Our algorithm infers physically-based plausible temperature and fuel density values from RGB data input from recorded real fires. These images have been overexposed for display purposes, please refer to Fig. 13 to see the unaltered output of our method.

“…Although the method in [Hul92] depicts flows using stream surfaces constructed by the polygonal tiling of adjacent pairs of streamlines, it is focused only on steady flow where all the time derivatives of the flow field vanish. For real‐time applications of the flame, Bridault and his colleagues [BLLR06, BLRR07] model flame shapes using NURBS surfaces. Although their approaches are similar to ours, smoke is more challenging because of complex behaviour and diffusive nature over time.…”

Incense, candle smoke and cigarette smoke often exhibit smoke flows with a surface-like appearance. Although delving into well-known computational fluid dynamics may provide a solution to create such an appearance, we propose a much efficient alternative that combines a low-resolution fluid simulation with explicit geometry provided by NURBS surfaces. Among a wide spectrum of fluid simulation, our algorithm specifically tailors to reproduce the semi-transparent surface look and motion of the smoke. The main idea is that we follow the traces called streaklines created by the advected particles from a simulation and reconstruct NURBS surfaces passing through them. Then, we render the surfaces by applying an opacity map to each surface, where the opacity map is created by utilizing the smoke density and the characteristics of the surface contour. Augmenting the results from low-resolution simulations such a way requires a low computational cost and memory usage by design.
