Modeling and rendering of large forest scenes are a challenging task, whose geometric complexity surpasses even the capabilities of current graphics hardware. ...
A fast forest rendering system is also developed. We present techniques in the system for rendering forest consisting of many highly detailed plant models. ...
Introduction It is still a challenge to render a large forest scene with interactive frame rates, since it consists of an extensive number of highly complex geometric models. ...

This paper investigates hybrid quantum-classical algorithms for ray tracing, a core component of most rendering techniques. ...
Rendering on conventional computers is capable of generating realistic imagery, but the computational complexity of these light transport algorithms is a limiting factor of image synthesis. ...
Boyer et al. (1998) proposed a hybrid quantum-classical algorithm to this problem, which still allows for a quadratic query complexity gain w.r.t. a classical approach. ...

In computer graphics, rendering is the process by which an abstract description of a scene is converted to an image. ...
When the scene is complex, or when high-quality images or high frame rates are required, the rendering process becomes computationally demanding. ...

In this paper, we present a solution for integrating realistic lighting simulation with interactive performance into a single VR application. ...
The main reason for this is that realistic lighting simulation is believed to require heavy offline processing and unfeasible to do from within a real-time system. ...
