Abstract: A method for enhanced forward rendering is disclosed which includes a depth pre-pass, light culling and a final shading. The depth pre-pass minimizes the cost of final shading by avoiding high pixel overdraw. The light culling stage calculates a list of light indices overlapping a pixel. The light indices are calculated on a per-tile basis, where the screen has been split into units of tiles. The final shading evaluates materials using information stored for each light. The forward rendering method may be executed on a processor, such as a single graphics processing unit (GPU) for example.

Abstract translation: 公开了一种用于增强前向渲染的方法，其包括深度预通，光剔除和最终阴影。 通过避免高像素过度抽取，深度预通行最小化最终着色的成本。 光剔除阶段计算与像素重叠的光指数的列表。 光指数以每瓦片为基础计算，其中屏幕已经被分割成瓦片的单位。 最终的阴影使用为每个灯存储的信息来评估材料。 前向渲染方法可以在诸如单个图形处理单元（GPU）的处理器上执行。
