Introduction to Mad Mapper and Projection Mapping

Overview

• Project: Starting a new project in Mad Mapper.
• Features: Disabling scenes and queues as they won't be used.
• Viewing: Input and output are viewed side by side.

Introduction to Projection Mapping

Basic Concept

• Input Shape: Create an input shape called a quad.
• Default Media: Assign default media, e.g., a black and white checkerboard.
• Fundamental Principle: Positioning of input relative to media changes output appearance.

Steps and Tasks in Mad Mapper

Creating Input Shapes

• Use formats (e.g., color patterns) to differentiate content on each quad.
• Assign pre-designed video content to the quads.

Using Overlapping Quads

• Hide overlapping quads by moving points to fit physical surfaces (e.g., boxes).
• Example: Projection mapping onto the front and top faces of a box. Each face can have different content.

Bringing in Content

• Import images (e.g., orthographic reference images of your house).
• Orthographic images don't contain perspective, which is crucial for accuracy.
• Create quads for each surface of the house for precise mapping.

Manipulating Masks in Mad Mapper

Creating Masks

• Define masks to exclude unwanted areas (e.g., roof parts).
• Use the freehand tool to click out points and draw shapes.
• Adjust masks by moving points, creating new points, or enabling Bezier handles.

Editing Masks

• Masks can be copied and pasted between quads for efficiency.
• Masks can be scaled and moved to fit new areas.
• Masks can be inverted to show or hide content inside them.

Adjusting Masks

• Refine initial shapes by editing points and lines.
• Ensure masks fit properly to eliminate overlapping errors.

Setting Up Projectors

Display Setup

• Ensure mirror displays are unchecked in system preferences (for Mac users).
• Assign each projector its destination through the settings.
• Use projector focus and positioning to cover the entire area.

Full-Screen Mode Output

• Select output and enable full-screen mode to see checkers or content on projections.

Adjusting for Resolution

• Maximize projector resolution by adjusting quads to fully use available pixels.
• Move projectors and adjust for uniform coverage.
• Use zoom lens adjustments on projectors as needed.

Precision Mapping

Matching Guide to Physical House

• Match input guide to physical house features for accuracy.
• Adjust points iteratively to ensure correct alignment.

Overlaying Projectors

• Boost brightness by overlaying projectors.
• Duplicate and position content across multiple projectors.

Final Adjustments

• Perform final adjustments to ensure all projectors align perfectly.
• Check exposure and focus settings.
• Use high contrast content for precise alignment.

Bringing Show to Life

• Replace the guide with the show content designed using the reference guide.
• Scrub through animation for high contrast frames to check alignment.
• Ensure audio settings are properly integrated.
• Finalize and play the show.
