Warp & blend
- Custom digital blending solutions with laser-guided alignment
- 25+ years of experience supported by in-house tools
- Precise projector alignment for any screen shape or size
Multi-projection warp and blend Services for a seamless single image
Portal Devices provide design and installation services to enable the precise layout of the projectors, the onsite alignment of the projections, and the configuration of the warp and blend hardware/software.
Project pixels onto any shape or size screen, or surface
Portal Devices can provide warp and blend design and installation services for any screen shape - flat, rectilinear, curved, cylindrical, domes, and planetariums.
When you want to project onto a screen or surface of any size or shape, you'll likely need more than one projector to cover the entire screen surface.
Portal Devices have over 25 years’ experience in projection display design and implementation, including a comprehensive understanding of the warp and blend process.
Warp and Blend
Warp and blend is the process of combining multiple projectors to create much larger single, seamless images.
Warping is the geometrical distortion and alignment of the projected images.
Blending solves the issue of increased brightness in the blend region, using optical or digital techniques.
Hardware or Software
Warp and Blend can be acheived through a variety of solutions.
For installations where multiple projectors are required to fill a large screen surface, hardware or software warp & blend solutions are available to suit complexity and budget.
Hardware or software solutions are suitable for theme parks, attractions, museums, simulators, planetariums, education, homeAV and corporate.
Portal Devices have extensive experience and great success with the following warp and blend solutions: Geobox, Scalable, Screenberry, VIOSO and SimVisuals.
Contact us to discuss your requirements and we can recommend a solution to suit your needs and budget.
Warping - is the geometrical 'shaping' of the projector's display output to match the screen shape.
For small installations with a simple screen shape where only 1 projector is required, the projector's onboard warp adjustment can be used to shape the display to match your screen.
For installations of 2 or more projectors, neighbouring projectors will have an overlap blend region. Warp adjustment is used to align the overlap regions.
Blending - is the process of matching the image brightness in the non-overlapped region with the image brightness of the blended region.
Blending is not required for installations of 1 projector.
For installations of 2 or more projectors, the projector images overlap, causing extra brightness in the overlapped region.
Optical, hardware or software solutions are used to match the brightness in the blend region to the unblended regions.
The geometry of the overlap is calculated during the design process to produce the best results.
The screen shape and size must be known to select the most appropriate projector to balance brightness, coverage and budget.
Optical Blend Masks
Optical blend masks are typically used in military simulation, high-end planetariums, for complex blend region shapes, and for dark scenes or night vision displays.
Portal Devices' POD Rigs provide integrated support for optical blend masks.
