Native. Integrated. Zero-Threshold Creation.
A light-weight, modular 3D content creation engine & editor built on the Processing P3D environment.
P3DE aims to prove that even within the minimalist Java-based artistic programming framework of Processing, it is possible to build a closed-loop toolchain with industrial-grade interaction, high-fidelity rendering, and visual logic editing.
The core technical bottom line of this project is: No third-party plugins or external Jar libraries were used throughout the entire process (such as ControlP5, PeasyCam, Rhino, etc.).
- Self-developed Gizmo System: Implemented based on pure vector mathematics and Raycasting.
- Native UI Rendering: All interfaces are drawn pixel-by-pixel using Processing's basic drawing instructions.
- Zero-dependency Script Engine (P3DES): Custom asynchronous execution and variable interpolation system.
- Native PBR Shaders: Cook-Torrance BRDF mathematical models written directly at the GLSL level.
- Professional Gizmo Manipulator: Supports Translate, Rotate, and Scale. Features real-time World/Local coordinate switching (
Lkey) and 10-unit grid snapping (Gkey). - Hierarchy Management Tree: Supports infinite depth of parent-child transformations with a right-click context menu.
- Undo/Redo: Built on the Command pattern, covering all core editing operations.
- GGX Cook-Torrance BRDF: Accurately simulates metalness and roughness.
- IBL (Image Based Lighting): Supports 360-degree environment map loading for realistic global illumination.
- Material Property Panel: Integrated color picker and real-time texture channel control.
- Dual Ownership: Blueprints can be attached to "Entities" or "Levels," enabling both object logic and global control.
- Compilation Engine: Translates non-linear node flows into executable P3DES instructions via DFS algorithm, supporting Hot-Reload.
- P3DEC (Direct Execution): Professional-grade instruction console.
- P3DES (The Script Brain): Lightweight asynchronous scripting language supporting non-blocking
waitinstructions. - Initialization Flows: Supports
init.p3decfor automated batch processing.
- Requirements: Ensure Processing 4 or higher is installed.
- Launch: Clone this repository and open
p3deditor/p3deditor.pdein the Processing IDE. - Run with Zero Dependencies: No libraries to install; just click Run to enter the editor.
1/2/3/4: Select / Translate / Rotate / Scale.L: Toggle between World and Local coordinate spaces.G: Toggle grid snapping.Tab: Hide/Show all UI.`(Backtick): Open/Close terminal console.
The birth of this project is the result of deep synergy between Yifan Shen and Antigravity (Google AI Coding Agent):
- Yifan Shen: Product vision, UX design, and top-level blueprint.
- Antigravity: Core architecture design, mathematical algorithm implementation, and engineering.
P3DE proves that with AI-assisted programming, developers can customize highly complex professional creation tools with minimal overhead.
P3DE is proudly built using Processing 4. We are grateful to the Processing Foundation and its community for providing such a powerful and accessible creative coding environment. Processing 4 is licensed under the GNU LGPL and GPL.
