Extensions

ToModel

Creates a simple IModel from this geometry.

method	ToModel (Model model, int32 faces = 0, int64 colorEdges = -1, int64 colorTriangles = 0x7FFFFFFFFFFFFFFF)
type	Model
params	model	[not-null]	The parent model that will get additional child models based on this geometry.
	faces		> 0 : show only front-facing triangles = 0 : show both front- and back-facing triangles < 0 : show only back-facing triangles Defaults to 0.
	colorEdges		The color to use for edges. Defaults to White.
	colorTriangles		The color to use for triangles. Defaults to semi-transparent White.
returns		[not-null]	The resulting model.

Creates a simple IModel from this geometry.

method	ToModel (int32 faces = 0, bool lighting = false, int64 colorEdges = -1, int64 colorTriangles = 0x7FFFFFFFFFFFFFFF)
type	Model
params	faces		> 0 : show only front-facing triangles = 0 : show both front- and back-facing triangles < 0 : show only back-facing triangles Defaults to 0.
	lighting		Enable lighting (see Lighting)? Defaults to false.
	colorEdges		The color to use for edges. Defaults to White.
	colorTriangles		The color to use for triangles. Defaults to semi-transparent White.

Methods

CreateResource

Creates a new resource object, using the given graphics context.

[OwnerReturn]
method	CreateResource (Graphics graphics)
type	IResource
params	graphics	[not-null]	The graphics context to use.
returns		[not-null]	The resource object.
inherited	IResourceHandle.CreateResource

Remarks:

Resource objects may implement the IMemoryConsumption interface. In this case, the reported memory consumption will be interpreted as an estimate on how much GPU memory is consumed by the resource. This estimate can then be used for resource caching (e.g. CacheMemory).

Exceptions:

• RenderException:
  If a graphics subsystem error has occurred.
• IOException:
  If an I/O error has occurred while reading the resource data.
• ValidatingException:
  If the data reader has reported an error, for example because of an unsupported file format feature.

Dynamic

Makes this model geometry dynamic.

method	Dynamic ()
type	IModelGeometryDynamic
returns		[not-null]	The dynamic model geometry.
inherited	IModelGeometry.Dynamic

Remarks:

If necessary, a new model geometry is created by copying index and vertex data from this model geometry.

Exceptions:

• IOException:
  If an I/O exception has occurred.

Equals

Compares this object with the given one.

[Pure]
method	Equals (IResourceHandle other)
type	bool
params	other		The object to compare to.
returns			true if this object is equal to other, false if not.
inherited	IEquatable.Equals

Instanced

Configures geometry instancing for this model geometry.

method	Instanced (IResourceHandle instanceBuffer)
type	IModelGeometry
params	instanceBuffer		The resource handle that returns an IVertexBuffer object that holds instance data to use for this model geometry object or null to disable geometry instancing. The instanceBuffer value will be returned by the IModelGeometry property of the returned model geometry object.
returns		[not-null]	The resulting model geometry.
inherited	IModelGeometry.Instanced

Optimized

Optimizes this model geometry by reordering those vertices that are actually referenced by the index data.

method	Optimized ()
type	IModelGeometry
returns		[not-null]	The optimized geometry, without instancing. Will be this if ReadIndices return null.
inherited	IModelGeometry.Optimized

ReadIndices

Read vertex index data.

method	ReadIndices ()
type	int32[]
returns			The vertex index data or null iff IndexCount returns 0 (i.e. the geometry is not indexed).
inherited	IModelGeometry.ReadIndices

Exceptions:

• IOException:
  If an I/O exception has occurred.

ReadVertices

Reads vertex data.

method	ReadVertices ()
type	VertexArrays
returns		[not-null]	The vertex data array.
inherited	IModelGeometry.ReadVertices

Exceptions:

• IOException:
  If an I/O exception has occurred.

Reduced

Reduce the floating-point precision for this model geometry?

method	Reduced (bool reduced)
type	IModelGeometry
params	reduced		Use 32-bit floating-point precision (true) or 64-bit floating-point precision ( false)?
returns		[not-null]	The reduced geometry.
inherited	IModelGeometry.Reduced

Remarks:

Using reduced precision will consume less memory resp. storage space, but might introduce jitter artifacts during rendering.

Transform

Transforms the model geometry using the given matrix.

method	Transform (Mat4D matrix)
type	IModelGeometry
params	matrix		The transformation matrix.
returns		[not-null]	The transformed geometry.
inherited	IModelGeometry.Transform
