    • Techniques for supporting both 2-D and 3-D graphics are described. A graphics processing unit (GPU) may perform 3-D graphics processing in accordance with a 3-D graphics pipeline to render 3-D images and may also perform 2-D graphics processing in accordance with a 2-D graphics pipeline to render 2-D images. Each stage of the 2-D graphics pipeline may be mapped to at least one stage of the 3-D graphics pipeline. For example, a clipping, masking and scissoring stage in 2-D graphics may be mapped to a depth test stage in 3-D graphics. Coverage values for pixels within paths in 2-D graphics may be determined using rasterization and depth test stages in 3-D graphics. A paint generation stage and an image interpolation stage in 2-D graphics may be mapped to a fragment shader stage in 3-D graphics. A blending stage in 2-D graphics may be mapped to a blending stage in 3-D graphics.
    • 描述了支持2-D和3-D图形的技术。 图形处理单元(GPU)可以根据3-D图形流水线执行3D图形处理以渲染3-D图像,并且还可以根据2-D图形流水线执行2-D图形处理以呈现2 -D图像。 2-D图形管线的每个阶段可以映射到3-D图形流水线的至少一个阶段。 例如,2-D图形中的裁剪,掩蔽和裁剪阶段可能被映射到3-D图形中的深度测试阶段。 2-D图形中路径内像素的覆盖值可以使用3-D图形中的光栅化和深度测试阶段来确定。 2-D图形中的油漆生成阶段和图像插值阶段可以映射到3-D图形中的片段着色器阶段。 2-D图形中的混合阶段可以映射到3-D图形的混合阶段。
