Creating and Rendering 3D Graphics in MetaTrader 5 with DirectX
Summary
This tutorial introduces the concepts and MQL5 tools for creating 3D scenes in MetaTrader 5 with DirectX. It explains how objects are represented as polygon meshes, how triangle vertices and surface normals support geometry and lighting, and how projection and camera coordinates turn a scene into a two-dimensional image. A cube example demonstrates scene creation, rendering, canvas updates, and handling chart resizing.
The article continues through camera movement, object rotation, color, lighting, animation, mouse control, textures, custom objects, and a data-driven 3D surface. It frames these techniques as ways to visualize analytical and optimization data within the terminal, with examples of animated surfaces and references to included sample programs. The material is a graphics programming guide rather than a trading strategy or evidence of improved trading performance. It also states a hardware requirement: the video card must support DirectX 11 and Shader Model 5.0.
Key ideas
- A 3D object can be represented by a mesh of triangles whose vertices define its shape.
- Surface normals help calculate lighting and reflections on each face.
- Rendering transforms object coordinates through camera and projection coordinates onto a canvas.
- Chart resizing requires updating the canvas dimensions and projection matrix.
- DirectX graphics can display animated or data-driven surfaces for visual analysis, subject to hardware support.
