Introduction to HoloScript

HoloScript is the spatial programming language for VR, AR, and 3D applications. It removes the abstraction barrier between humans and computation—instead of writing text that a machine interprets, you manipulate computation directly as spatial objects.

Why HoloScript?

For Humans

• No syntax errors - Visual/declarative approach eliminates brackets and semicolons
• Universal input - Voice, gesture, gaze, or traditional keyboard
• See the data flow - Watch computation happen in 3D space

For AI

• Visual understanding - AI "sees" program structure
• Native manipulation - AI can place and connect objects naturally
• Any output target - Generate code for any platform

For Computing

• One source → 9 platforms - Web, VR, AR, mobile, desktop, Unity, Unreal, VRChat
• 50,000 → 500 lines - Declarative syntax eliminates boilerplate
• Built for collaboration - Human and AI work in the same space

File Formats

HoloScript uses three file formats:

Extension	Purpose	Best For
.hs	Classic HoloScript	Simple prototypes, learning
.hsplus	HoloScript Plus	VR traits, networking, physics
.holo	Composition	AI-generated scenes, full worlds

Quick Start

Install the VS Code extension:

ext install holoscript.holoscript-vscode

Create your first scene:

composition "Hello World" {
  environment {
    skybox: "gradient"
    ambient_light: 0.5
  }

  object "Cube" {
    @collidable
    position: [0, 1, -3]
    color: "#00ffff"
  }
}
