Coordinated multi-display, multi-GPU output

Multi-Channel Rendering

Coordinated rendering across multiple viewports, displays, and GPUs for command walls, curved screens, and CAVE systems.

Overview

Command-center walls, curved screens, immersive CAVE spaces, and video walls need multiple images to present the same 3D world with precise synchronization and seamless tiling. Multi-channel rendering lets DawnEngine coordinate output across viewports, displays, and even multiple GPUs / nodes, ensuring consistency and smoothness.

Key Capabilities

  • Multi-viewport / multi-window: render the same scene from multiple views/windows simultaneously.
  • Tiling and edge blending: support image tiling and edge blending for a seamless large image.
  • Frame sync: synchronize frames across channels/nodes to avoid tearing and misalignment.
  • Multi-GPU / multi-node: distribute rendering load across GPUs or machines.
  • Large-world coordination: present large-scale scenes with World Partition and Cesium.

Use Cases

  • Command-and-control centers and emergency-response walls.
  • Curved-screen theaters and immersive CAVE simulation spaces.
  • Large video walls and multi-view visualization.

Multi-channel rendering is a “presentation” capability that can drive local displays or combine with pixel streaming for cloud-side multi-channel output, carrying large-world and real-geography content.
