addMesh
Description
Input Arguments
actor
— Actor class where property is being added
sim3d.Actor
object
Actor class where mesh is being added, specified as a sim3d.Actor
object.
vertices
— Vertex positions
N-by-3 matrix
Vertex positions, specified as an N-by-3 matrix. This matrix includes the coordinates of all vertex positions to be used for the mesh geometry. Each vertex has a vertex ID equal to its row number in the matrix. N specifies the number of vertices.
Example: vertices = [-1 -1 0; 1 -1 0; 1 1 0; -1 1 0; -1 -1 0; 1 -1 0;1 1 0;-1 1
0]
Data Types: double
faces
— Vertices of each triangular face
M-by-3 matrix
Vertices of each triangular face, specified as an M-by-3 matrix. This matrix defines how each triangle of the mesh is drawn. The matrix specifies the vertex IDs that define each triangular face of the mesh. M is the number of triangular faces in the mesh.
Example: faces = [0 3 2; 0 2 1; 4 6 7;
4 5 6]
Data Types: double
normals
— Normal vectors of each vertex
N-by-3 matrix
Normal vectors of each vertex, specified as an N-by-3 matrix. Each
row of the matrix specifies the normal vector for a vertex. This matrix must be the same
size as vertices
matrix.
Example: normals = [0 0 1; 0 0 1; 0 0 1; 0 0 1; 0 0 -1; 0 0 -1; 0 0 -1; 0 0
-1]
Data Types: double
vcolor
— Vertex colors
N-by-3 matrix
Vertex colors, specified as an N-by-3 matrix. This matrix specifies the
color value of each vertex in the [R G B]
form. This matrix must be the
same length as vertices
.
Note
To display vcolor
along with the actor base color, set the
VertexBlend
property to a value greater than 0. If
VertexBlend
is 1, then actor displays only the
vcolor
.
Example: vcolor = [1 0 0; 0 1 0; 0 0 1; 1 0 1; 1 1 0; 0 1 1; 1 1 0; 0 1
0]
Data Types: double
tcoords
— Texture coordinates
N-by-2 matrix
Texture coordinates for each vertex, specified as an N-by-2 matrix. This
matrix defines which point on the texture file maps to each of
the vertices. This matrix must be the same length as
vertices
.
Example: tcoords = [0 0; 0 1; 1 1; 1 0; 0 0; 0 1; 1 1; 1 0]
Data Types: double
