Abstract
Limited by performance of hardware, electronic displays cannot reach the actual brightness of glowing objects, but the method of using glare illusions to simulate real light sources has been widely studied. These studies mainly focused on exploring the influence of gradients on brightness perception. As one of the basic perception characteristics of light sources, it is still unknown whether radial streaks will affect people's perception of light sources. Based on previous researches, we propose a new rendering model of self-luminance objects, which can effectively simulate the radial streaks formed by diffraction of light. By a Maximum Difference Scaling experiment, the influence of streak intensity, luminance gradient and streak fusion state on the fidelity of the light source is further explored. We found that streak intensity and fusion state can effectively improve the realism of virtual light sources.
