混合场景绘制的光照一致性研究(英文)

Illumination Consistency of Hybrid Scene Rendering

光照计算是真实感图形绘制的重要的研究问题之一,调整光照效果是增强真实感效果最关键的一步,特别是在基于几何与图像混合绘制的系统中,调整图像的光照适应当前虚拟环境的光照是一个复杂的过程。利用三维模型在GPU中的绘制流程,在混合场景绘制系统中,提出了一种简单的光照一致性方法,生成虚拟场景绘制系统中动态光照下的图像模型,图像的光照随着虚拟光照环境的改变,与几何模型的光照具有一致性。

The illumination makes an important role in realistic graphics rendering and most image related applications, especially in the hybrid rendering based on the geometry and image. Adjusting the illumination effect is a key step to achieve realistic scene when the images based on sampling are inconsistent with the environment on the illumination circumstance. Therefore, complicated processing was required to generate the image with desired illumination condition. Using three-dimensional model of the GPU rendering process, a simple method was proposed to generate dynamic illumination of image-based objects in a hybrid scene rendering system, and the illumination of the image was changed with the virtual lighting condition and keeps consistency with the illumination of geometry models.
