Class SurfaceOrientation.Builder

java.lang.Object

com.google.android.filament.SurfaceOrientation.Builder

Enclosing class:

SurfaceOrientation

public static class SurfaceOrientation.Builder
extends java.lang.Object

Constructs an immutable surface orientation helper. At a minimum, clients must supply a vertex count. They can supply data in any of the following combinations:

1. normals only (not recommended)
2. normals + tangents (sign of W determines bitangent orientation)
3. normals + uvs + positions + indices
4. positions + indices

Additionally, the client-side data has the following type constraints:

1. Normals must be float3
2. Tangents must be float4
3. UVs must be float2
4. Positions must be float3
5. Triangles must be uint3 or ushort3
