enum VertSemantic

What a vertex component means! This is matched against the semantics the shader’s vertex inputs declare, so component order in a format doesn’t need to match the shader’s input order.

Enum Values


Binormal	Binormal/bitangent direction for normal mapping.
Blendindices	Bone indices for skinning.
Blendweight	Bone weights for skinning.
Color	Vertex color.
None	Invalid semantic, this is not a valid value for a component.
Normal	Direction the vertex is facing.
Position	Vertex position, in model space coordinates.
Psize	Point size for point rendering.
Tangent	Tangent direction for normal mapping.
Texcoord	Texture coordinates.

Examples

Custom vertex formats

Meshes can use custom vertex layouts! Define a struct that provides what your shader’s vertex stage needs, and tag each field with a VertComponent attribute saying what it is. StereoKit derives the vertex format from the struct automatically. Since vertex data is matched to shader inputs by semantic, fields don’t need to be in the same order as the shader declares them!

[StructLayout(LayoutKind.Sequential, Pack = 1)]
struct VertPosColor
{
	[VertComponent(VertSemantic.Color,    VertFmt.U8Normalized, 4)]
	public Color32 color;
	[VertComponent(VertSemantic.Position, VertFmt.F32,          3)]
	public Vec3    pos;

	public VertPosColor(Vec3 position, Color32 c) { pos = position; color = c; }
}

Mesh     _mesh;
Material _material;

Mesh BuildOctahedron(float s)
{
	Mesh mesh = new Mesh();
	mesh.SetVerts(new VertPosColor[] {
		new VertPosColor(V.XYZ( s, 0, 0), new Color32(255,  0,  0,255)),
		new VertPosColor(V.XYZ(-s, 0, 0), new Color32(  0,255,  0,255)),
		new VertPosColor(V.XYZ( 0, s, 0), new Color32(  0,  0,255,255)),
		new VertPosColor(V.XYZ( 0,-s, 0), new Color32(255,255,  0,255)),
		new VertPosColor(V.XYZ( 0, 0, s), new Color32(  0,255,255,255)),
		new VertPosColor(V.XYZ( 0, 0,-s), new Color32(255,  0,255,255)) });
	mesh.SetInds(new uint[] {
		2,4,0,  2,0,5,  2,5,1,  2,1,4,
		3,0,4,  3,5,0,  3,1,5,  3,4,1 });
	return mesh;
}
