BBMOD_MeshBuilder

Extends BBMOD_Class

constructor

new BBMOD_MeshBuilder()

Description

Allows you to build meshes through code.

Properties

Name Description
Faces List of vertex indices that make up a face. First three indices are the first face, next three indices are the second face etc.
Vertices List of mesh vertices.

Methods

Name Description
add_face Adds a face to the mesh.
add_vertex Adds a vertex to the mesh.
build Builds a mesh from the added vertices and faces.
make_tangents Makes tangent and bitangent vectors for added vertices.

Example

Following code shows how you can create a plane mesh using the mesh builder.

var _meshBuilder = new BBMOD_MeshBuilder();
var _vertexFormat = new BBMOD_VertexFormat(true);
var _v1 = new BBMOD_Vertex(_vertexFormat);
_v1.Position = new BBMOD_Vec3(0.0, 0.0, 0.0);
var _v1Ind = _meshBuilder.add_vertex(v1);
var _v2 = new BBMOD_Vertex(_vertexFormat);
_v2.Position = new BBMOD_Vec3(1.0, 0.0, 0.0);
var _v2Ind = _meshBuilder.add_vertex(v2);
var _v3 = new BBMOD_Vertex(_vertexFormat);
_v3.Position = new BBMOD_Vec3(1.0, 1.0, 0.0);
var _v3Ind = _meshBuilder.add_vertex(v3);
var _v4 = new BBMOD_Vertex(_vertexFormat);
_v4.Position = new BBMOD_Vec3(0.0, 1.0, 0.0);
var _v4Ind = _meshBuilder.add_vertex(v4);
_meshBuilder.add_face(_v1, _v2, _v4);
_meshBuilder.add_face(_v2, _v3, _v4);
var _mesh = _meshBuilder.build();
