Rendering & Light

Renderer & Drawing Modes

Control face selection, visibility, lighting, occlusion, and the TradingView primitive backend used to carry projected 3D geometry.

One call per frame

Renderer signaturepine

p3d.render(scene,
  maxFaces = 100,
  culling = true,
  lighting = false,
  ambient = 0.3,
  wireframe = false,
  occlusion = true,
  occlusionRaster = 768)

Frame pipeline

World transform, camera transform, back-face culling, occlusion culling, depth sorting, lighting and shadows, perspective projection, then drawing output.

Renderer parameters

Parameter	Default	Purpose
`maxFaces`	100	Caps solid faces. Contour paths, wireframes, and overlays use their own drawing budgets.
`culling`	true	Removes back-facing polygons.
`lighting`	false	Enables diffuse shading and scene light evaluation.
`ambient`	0.3	Sets minimum face brightness when passed explicitly.
`wireframe`	false	Forces scene-wide outline output.
`occlusion`	true	Drops hidden faces with a sparse raster pass.
`occlusionRaster`	768	Sets occlusion buffer resolution. Lower values are faster and coarser.

Mesh styles

Style	Result
solid	Filled faces.
wireframe	All edges with no fill, including interior geometry.
wireframe_front	Front-facing edges only for a cleaner convex silhouette.

The recommended backend uses lines and linefills with adaptive rail sharing. Adjacent coplanar faces can reuse an edge rail, increasing practical face capacity. It supports in-place updateSurface() and updateBars().

poly

The legacy polyline backend supports styled solid-face outlines but has lower capacity and no in-place surface or bar updates. Use it only when those visible outlines are required.

Wireframes are independent

Wireframe styles always use line primitives regardless of the solid-face draw mode.

Drawing clear behavior

At the start of every call, render clears chart polylines, lines, labels, and linefills before emitting the current frame.

Create manual drawing objects after rendering if they must remain.
Tables are not cleared and work well for debug or budget monitors.
Explicit render arguments override matching scene-light settings for that frame.
