What are the benefits of multiple pass rendering?
Multiple-pass rendering improves performance because it breaks up complex scenes into tasks that can run concurrently. To perform multiple-pass rendering, you create a deferred context and command list for each additional pass.
How does deferred rendering work in Direct3D 11?
Deferred rendering is a new concept in Direct3D 11; deferred rendering is designed to support rendering on one thread while recording commands for rendering on additional threads. This parallel, multithread strategy allows you to break up complex scenes into concurrent tasks.
What is the difference between immediate rendering and deferred rendering?
Immediate Rendering. Immediate rendering refers to calling rendering APIs or commands from a device, which queues the commands in a buffer for execution on the GPU. Use an immediate context to render, set pipeline state, and play back a command list.
How to use a command list in deferred rendering?
To use a command list, record rendering commands with a deferred context and play them back using an immediate context. You can generate only a single command list in a single-threaded fashion. However, you can create and use multiple deferred contexts simultaneously, each in a separate thread.
What is the purpose of batching in spritebatch?
Sprite batching then is doing that very thing: putting as many of your sprites as possible into a single VBO using a single atlas that is submitted to the GPU with a single draw call, maximizing GPU usage.
Can you edit a multi pass image in Photoshop?
The Multi-Pass rendering and RLE/RPF bitmap format make it possible to edit rendered images in a wide variety of ways and with a variety of applications, including Photoshop and BodyPaint 3D in which Multi-Pass layers can be used.
What do the multi pass channels do in Photoshop?
The Multi-Pass channels contain information regarding the scene’s corresponding material channel (e.g., the Material Color Pass channel contains the material color for every object in the scene). These special channels are irrelevant for the normal user. Plugin developers can, however, make use of these channels.
