Bạn có thể nhìn thấy những chiếc máy bay đang chồng chéo trong Viewport Họ là bóng mờ trong một màu đỏ Darker. | Creating 3D Game Art for the iPhone with Unity FIG This Image Uses Unity s Overdraw Viewport Rendering to Help Visualize the Concept of Overdraw. You Can See the Planes that Are Overlapping in the Viewport as They Are Shaded in a Darker Red Color. information. This data which is associated with the fragment is interpolated from the transformed vertices of the geometry or the texture in memory. If the fragment passes the rasterization tests that are performed at the raster stage on the GPU the fragment updates the pixel in the frame buffer. I like to think of a fragment as the DNA so to speak of a pixel. In Fig. you can see an illustration that represents fragment data as it relates to an actual pixel. A tile-based renderer will divide up the screen into smaller more manageable blocks called tiles and will render each one independently. This is efficient especially on mobile platforms with limited memory bandwidth and power consumption such as the iPhone and iPad. The FIG A Fragment Represents the Data of the 3D Model and Can Be Interpolated into a Pixel Shown on Screen. smaller the tile the GPU is rendering the easier it is to process and thus the less it has to go out to the shared memory of the system and ultimately utilizes less memory bandwidth. The TBD renderer also uses less power consumption and utilizes the texture cache in a more streamlined fashion which again is very important on the iPhone due to memory limitations. The iPhone has a dedicated unit to handle vertex processing which runs calculations in parallel with rasterization. In order to optimize this the vertex processing happens one frame ahead of rasterization which is the reason for keeping the vertex count below 10 K per frame. 10 Getting to Know the iDevice Hardware and Unity iOS FIG I like to Visualize the TBD Renderer of the iPhone to Be Similar to Modo s Bucket Rendering. Again as a 3D artist it helped me to visualize the TBD tenderer on the iPhone to be similar to the .
