Public API

Method	Description
`SceneRenderer(GraphicsDevice&)`	Constructor. Builds all pre-computed unit meshes (box, sphere, cylinder, cone, plane) and wire shapes. Must be called after the GL context is ready.
`draw(doc, view, proj, selected)`	Renders the complete scene. Traverses `doc.objects` recursively. Also draws light/camera/CSG gizmos.
`clearCsgCache()`	Clears the cached Manifold CSG meshes. Must be called after any document mutation (done automatically in `pushUndo()`).
`setAnimOverrides(overrides)`	Injects per-object animation overrides. Called each frame before `draw()` when an animation is playing.
`drawGizmo(obj, view, proj, length)`	Draws the Move gizmo (axis arrows + cube tips) for the given object.
`drawScaleGizmo(obj, view, proj, length)`	Draws the Scale gizmo (axis lines + flat-square tips).
`drawRotateGizmo(obj, view, proj, length)`	Draws the Rotate gizmo (arc circles in XYZ planes).
`drawObjectWireframe(obj, view, proj, color)`	Draws a wireframe bounding box around an object in the given color.
`drawLightGizmos(lights, view, proj)`	Draws representative icons for each light in the scene.
`drawCameraGizmos(cameras, view, proj)`	Draws camera frustum icons.
`drawCsgGizmos(doc, view, proj)`	Draws per-CSG-node colored overlays.
`drawEdgeOverlay(doc, view, proj)`	Draws black wireframe lines over all visible objects (Alt+W toggle).

Private Helper Methods

Method	Description
`drawObject(obj, doc, parentWorld, …)`	Recursive per-object render. Dispatches by `ObjectType`.
`drawMesh(mesh, world, view, proj, color)`	Renders a `RenderMesh` with flat color using `BasicEffect`.
`drawMeshTextured(mesh, world, view, proj, color, tex)`	Renders with a texture using `BasicEffect` in texture+lit mode.
`loadOrGetTexture(absPath)`	Lazy-loads and caches a `Texture2D` from an absolute path.
`loadOrGetMesh(absPath)`	Lazy-loads and caches an OBJ file via tinyobjloader.
`objectWorldMatrix(transform)`	Builds the local world matrix using the pivot-compensated formula.
`materialColor(matId, doc)`	Looks up the `baseColor` from the document's material map. Returns a default grey if not found.
`isSelected(obj, sel)`	Returns true if the object pointer appears in the selection vector.

Caches

map<string, Texture2D>              textureCache_;   // keyed by abs path
map<string, RenderMesh>              meshCache_;      // keyed by abs path (OBJ)
map<const Mc3Object*, RenderMesh>    csgMeshCache_;   // keyed by object pointer
unordered_map<string, AnimOverride> animOverrides_;  // keyed by object name

The CSG cache (csgMeshCache_) is cleared on every pushUndo() call to ensure CSG geometry is re-evaluated after any edit. Texture and mesh caches are never cleared during a session.
