Abstract

Using recent graphics hardware called GPU (Graphics Processing Unit), we can render high quality photorealistic images in real-time today. When rendering the scene, it is important to take into account how human eyes percept the whole scene. Glare is a phenomenon whereby bright light source cause spreading of light, and this effect is widely used in computer graphics to enhance reality of brightness of the scene. Real-time rendering of glare images is very important for recent computer games and virtual reality environment. Current technology for high quality glare rendering is too slow to be used for interactive applications, and fast rendering technology is limited to generate only blurry glare images. In this paper we introduce new technique for rendering high quality glare images in real-time using the latest technology called vertex texture fetch. The basic idea is to put what we call degenerate polygons on the screen as sensors to detect bright pixels and expand those polygons to form glare polygons where glare images are put. Combined with some performance enhancement techniques, our method can render very high quality glare images as fast as 60fps using modern GPUs.
