Mesh
open class Mesh
| kotlin.Any | |
| ↳ | android.graphics.Mesh |
Class representing a mesh object. This class represents a Mesh object that can optionally be indexed. A MeshSpecification is required along with various attributes for detailing the mesh object, including a mode, vertex buffer, optional index buffer, and bounds for the mesh. Once generated, a mesh object can be drawn through Canvas#drawMesh(Mesh, BlendMode, Paint)

Mesh
Mesh(

mode: Int,
vertexBuffer: Buffer,
vertexCount: Int,
bounds: RectF)
Constructor for a non-indexed Mesh.
| Parameters | |
|---|---|
meshSpec |
MeshSpecification: MeshSpecification used when generating the mesh. This value cannot be null. |
mode |
Int: Determines what mode to draw the mesh in. Must be one of Mesh#TRIANGLES or Mesh#TRIANGLE_STRIP Value is android.graphics.Mesh#TRIANGLES, or android.graphics.Mesh#TRIANGLE_STRIP |
vertexBuffer |
Buffer: vertex buffer representing through Buffer. This provides the data for all attributes provided within the meshSpec for every vertex. That is, a vertex buffer should be (attributes size * number of vertices) in length to be valid. Note that currently implementation will have a CPU backed buffer generated.
