However,this research has focused on realistic rendering algorithms such as ray and path tracing, which take seconds or minutes to render.Ve y little work has been done on perceptually d iven interactive rendering,whe e each image must be completed in milliseconds.Yet a dire need exists for techniques to accelerate interactive rendering of ever-la ger datasets,fo despitetremendous strides in graphics hardware,the growth in complexity of 3-D models appears to beoutstripping our ability to render them.One barrier to research on perceptually motivated interactive rendering acceleration methods has been the inflexibility of standard graphics hardware.The rendering pipeline, specialized and perfected over many yea s,is now extremely fast at a narrow set of rendering tasks,but researchers cannot tamper with the traditional polygon-rendering underpinnings. We propose to circumvent this barrier by using software rendering,distributed across a cluster to achieve interactive ates on complex scenes.This SGER focuses on building the equipment necessa y to analyze several perceptual rendering techniques impossible under the traditional polygon-oriented interactive rendering paradigm.
