PrimitiveMesh (Mibo)

PrimitiveMesh Type

Namespace: Mibo.Elmish.Graphics3D
Assembly: Mibo.MonoGame.dll
Base Type: obj
All Interfaces: IEquatable<PrimitiveMesh> , IStructuralEquatable , IDisposable

Effectless procedural geometry — the MonoGame analog of raylib's universal Mesh. Wraps a VertexBuffer + IndexBuffer plus a primitive count.

Per §4.1 of the monogame3d plan, PrimitiveMesh is the unit that Material3D (the PBR-param carrier) is allowed to pair with — unlike ModelMeshPart, it owns no Effect, so there is no material conflation. The pipeline (ForwardPipeline) binds the active camera matrices and lighting onto a BasicEffect (B5/B6) or the custom PBR Effect (B9) when drawing.

Record fields

Record Field	Description
`Bounds` Full Usage: `Bounds` Field type: `BoundingSphere`	Local-space bounding sphere (unit primitives centered on origin). Used by the shadow pass to frustum-cull caster meshes per light (B11). Transform by the draw's world matrix to get the world-space sphere. Field type: `BoundingSphere`
`Indices` Full Usage: `Indices` Field type: `IndexBuffer`	Index buffer (16-bit, `IndexElementSize.SixteenBits`). Field type: `IndexBuffer`
`PrimitiveCount` Full Usage: `PrimitiveCount` Field type: `int`	Number of triangles (primitive count for `DrawIndexedPrimitives`). Field type: `int`
`Vertices` Full Usage: `Vertices` Field type: `VertexBuffer`	Vertex buffer holding VertexPositionNormalTexture vertices. Field type: `VertexBuffer`

Instance members

Instance member	Description
`this.Dispose` Full Usage: `this.Dispose`	Releases the underlying GPU buffers. Idempotent.
`this.Draw` Full Usage: `this.Draw` Parameters: gd : `GraphicsDevice` effect : `Effect`	Draws this primitive with a configured effect. Binds the vertex/index buffers, applies each pass of the effect's current technique, and issues a single `DrawIndexedPrimitives` per pass. The caller is responsible for setting `World`/`View`/`Projection` (and lighting) on the effect first. gd : `GraphicsDevice` effect : `Effect`
