Instance Property

geometryType

The type of geometric primitives described by the submesh’s index buffer.

Declaration

var geometryType: MDLGeometryType { get }

Discussion

This property determines how the sequence of indices in the submesh’s index buffer should be interpreted for rendering. For example, if the geometry type is MDLGeometryType.triangles, each triangle to be rendered comes from an independent set of three indices, but if the geometry type is MDLGeometryType.triangleStrips, triangles to be rendered can come from overlapping sets of indices in the sequence. If the geometry type is MDLGeometryType.variableTopology, the topology property describes the non-uniform layout of the index buffer.
