With edge overlap natively supported at the GPU level and no scaling required, M-Series cards provide outstanding image quality for all standard applicationsacross the entire desktopfor a very effective, collaborative work environment. NVAPI Warp and Blend API makes our technology application independent. The Matrox PowerDesk Edge Overlap feature allows M-Series 1 users to easily and intuitively adjust the number of overlapping pixels between edge blending projectors to create a seamless, unified image.Scalable Display Technologies is leader in auto-calibration for multi-projector displays.The application independence is essential to make it a “turn key” solution. This “Low Cost” simulator ($500K) by Immersive Display Solutions and using Scalable software, requires no warping box hardware which helps keep costs down.

It will be the first install to use NVIDIA warp and blend API. MIT Lincoln Labs – 20MPixel Touch Wallġ2 Projectors systems using dual Quadroplexes, it is a prototype design for a virtual shopping aisle system. Navy Combat System DisplayĪegis Combat System Display: 22 Cruisers have been delivered and there are 62 Destroyers to follow with systems in U.S, Japan, Spain, Norway, Korea and Australia.

Edge blending projectors software#

Leading provider of auto-calibration software for seamless multiple-projectors displays.

Define Intensity Map: GL_RGB value for each pixel.

How Is It Done: Blending (Intensity Adjustment)

Use NvAPI_GPU_GetScanoutConfiguration() to get current desktop.

Edge blending projectors driver#

Multiple screen capability coming with R285 driver (mid September)

Currently it works with single screen.

New interfaces are added in the 275+ NDA version to allow warping and intensity adjustment before the final scanout.

NVAPI is Nvidia’s programmatic interface to configure and control the GPU’s –.

Typical warping mesh contains 1K to 10K vertices.

Create warping mesh based on picture of the calibration pattern relative to the true image.

Use it with G-sync to get synchronization between displays.

Works on Quadro 5000, 6000, and Quadro Plex 7000.

By doing this on the GPU we have more flexibility: high quality filtering, integration with NVIDIA Mosaic, etc.

GPUs perform the transformation in the display pipeline before the pixels get scanned out.

GPUs are fast and already have the pixel information.

NVIDIA can do this on the GPU, which has several important advantages:

There has not been an easy way to implement this for any application, until now….

Applications need to be written to manage the display for every use-case.

Extra-performance delay tax on the display pipeline.

Hardware appliance for warp and intensity adjustment.

Up until now, warp and blend for projection displays has been done in one of the following two ways: But to be truly seamless, there is a need to account for geometry and brightness differences between projectors.

How to project on dome and curved screens?Ĭurrently Nvidia Mosaic allows you to specify overlap.

This creates a hotspot since the overlap region gets twice the light:

Projectors overlap the edges to hide the seam.

Some of the solutions to adding more pixels: Increases in pixel density and total pixels have not kept pace with increases in CPU and GPU power. DS2 units are able to run standalone without the connection to the control PC, once configured.Authors: Steve Nash (NVIDIA), Paul Green (Scalable Display Technologies). The Windows based software provides a user friendly GUI, greatly simplifying the system configuration.

The bonus of having the 4K media player built in is that the user does not need to worry about adding extra devices to their project.ĭS2 units can be easily configured via IP connection or RS232 to a Windows based PC running SEADAs management software. Moreover, DS2 also has an embedded 4K media player which enables DS2 to output a 4K video source played locally in addition to two captured HDMI video sources. In addition to its edge blending ability at the output sides, DS2 is able to capture one HDMI video source and display that onto the projection screen anywhere and any size. SEADA provide two different versions of the DS2, one with 3 HDMI outputs and another with 9 HDMI outputs. It is not only able to blend up to nine projectors together into one flat seamless display but also able to warp geometries on non-standard surfaces to form a curved or spherical projection surface. The DS2 is the device from SEADA that combines an edge blender, video wall controller and a 4K media player together in one unit.
