Cara Membuat Video Mapping pada Bangunan | Mapping the Building Workshop by Tedi Mursalat Farqo

Key Concepts

• Projection Mapping (Prod Mapping): A visual art form using projector technology to transform objects into interactive displays.
• Video Mapping: A broader term encompassing projection mapping but can also include other display technologies like TVs or LEDs.
• Resolume Arena: A software used for projection mapping, allowing for content input, output manipulation, and mapping onto surfaces.
• Slicing: The process of dividing a single video or image into multiple sections to map onto different parts of a 3D object.
• Masking: Using shapes (circles, triangles, etc.) to isolate specific areas of a video or image for projection.
• Output Monitor: The area in Resolume Arena that displays the final projection output.
• Preview Monitor: The area in Resolume Arena that allows you to preview content before sending it to the output.
• Edit Points: A feature in Resolume Arena that allows you to adjust the corners of a projection to precisely fit a surface.
• FPS (Frames Per Second): The rate at which frames are displayed in a video. Lower FPS can reduce the processing load on the computer.

Video Mapping: An Introduction

• Projection mapping is a visual art that uses projectors to transform objects into interactive displays.
• Video mapping is a broader term that can include other display technologies like TVs or LEDs.
• The studio specializes in video mapping, focusing on creating immersive experiences rather than traditional advertising.
• The studio was founded in 2012 by alumni of DKV ITS (Visual Communication Design, Institute Technology Sepuluh Nopember), officially starting as a studio in 2017.
• The studio has received national and international awards, including a MURI award for the largest outdoor projection mapping on a building in Colomadu.
• The team consists of around 20 people, including technicians, content creators, and project managers.

How Projection Mapping Works

• Four-Step Process:
  1. Content Creation: Creating the visual content to be projected.
  2. PC and Software: Using a computer and video mapping software to manage the content.
  3. Distribution: Sending the content to the projector.
  4. Projection: Projecting the content onto the chosen surface.
• Key Considerations:
  • Visual Concept: Developing a strong visual concept is crucial.
  • Surface Selection: Choosing the right surface to project onto.
  • Hardware Preparation: Selecting the appropriate hardware, including a PC/laptop and projector.

Hardware: Projectors

• Projector Categories:
  • Small: Suitable for small audiences and indoor exhibitions, with limited brightness (up to 3,000 lumens) and resolution.
  • Medium: Suitable for audiences of up to 1,000 people, with full HD resolution and up to 8,000 lumens.
  • Large: Used for large-scale projections on buildings, requiring high brightness, 4K resolution, and interchangeable lenses.
• Projector Selection: The choice of projector depends on the size of the audience, the ambient light, and the size of the projection surface.

Software: Resolume Arena

• Interface Overview:
  • Decks: The top section where content is loaded and organized in layers.
  • Output Monitor: The bottom section that displays the final projection output.
  • Preview Monitor: The bottom section that allows you to preview content before sending it to the output.
  • Controller: The right section that provides controls for effects, RGB, hue, and timeline.
• Workflow:
  1. Content Input: Drag and drop content into the decks.
  2. Output Selection: Choose the correct display output (projector) in the "Output" menu.
  3. Slicing: Use the "Input" tab to slice the content into specific shapes or sections.
  4. Mapping: Use the "Output" tab to adjust the position, size, and perspective of the sliced content to fit the projection surface.
  5. Edit Points: Use the "Edit Points" feature to precisely align the corners of the projection with the surface.
• Extending Display: The computer's display settings must be set to "extend" the display to the projector, not "mirror."

Mapping Basic Shapes (Kotak, Bulat, Segitiga)

• Kotak (Square):
  1. Slice the content into a rectangular shape using the "Input" tab.
  2. Adjust the position, size, and perspective of the rectangle in the "Output" tab to fit the square surface.
  3. Use the "Edit Points" feature to precisely align the corners of the projection with the square surface.
• Bulat (Circle):
  1. Use the masking feature to create a circular mask.
  2. Adjust the position and size of the circle to fit the circular surface.
• Segitiga (Triangle):
  1. Use the polygon tool to create a triangular shape.
  2. Adjust the position, size, and perspective of the triangle to fit the triangular surface.
  3. Use the "Edit Points" feature to precisely align the corners of the projection with the triangular surface.

Mapping Complex Surfaces (Gedung)

• Process:
  1. Divide the surface: Divide the building facade into multiple sections based on its geometry (e.g., front, sides, top).
  2. Slice the content: Create separate slices for each section.
  3. Map each slice: Adjust the position, size, and perspective of each slice to fit its corresponding section on the building.
  4. Fine-tune: Use the "Edit Points" feature to precisely align the corners of each projection with the building's features.
• Considerations:
  • Detail: More complex surfaces require more detailed slicing.
  • Perspective: Adjust the perspective of each slice to account for the building's geometry.
  • Precision: Precise alignment is crucial for a seamless projection.

Multiple Content Sources

• Challenge: Projecting different content onto different shapes simultaneously using a single projector.
• Solution:
  1. Reduce Content Size: Scale down the size of each content source within Resolume Arena.
  2. Position Content: Position each content source in a different area of the Resolume Arena output.
  3. Create Slices: Create separate slices for each shape, each slice targeting a different content source.
  4. Map Slices: Map each slice to its corresponding shape on the projection surface.
• Trade-off: This method may reduce the resolution of the projected content.

Additional Tips

• FPS: Use a frame rate of 30 FPS for smoother playback without excessive processing load.
• Content Creation: Create content that is specifically designed for projection mapping to optimize the visual impact.
