</brief_description>
<description>
A mesh type optimized for creating geometry manually, similar to OpenGL 1.x immediate mode.
Here's a sample on how to generate a triangular face:
[codeblocks]
[gdscript]
var mesh = ImmediateMesh.new()
mesh.surface_begin(Mesh.PRIMITIVE_TRIANGLES)
mesh.surface_add_vertex(Vector3.LEFT)
mesh.surface_add_vertex(Vector3.FORWARD)
mesh.surface_add_vertex(Vector3.ZERO)
mesh.surface_end()
[/gdscript]
[csharp]
var mesh = new ImmediateMesh();
mesh.SurfaceBegin(Mesh.PrimitiveType.Triangles);
mesh.SurfaceAddVertex(Vector3.Left);
mesh.SurfaceAddVertex(Vector3.Forward);
mesh.SurfaceAddVertex(Vector3.Zero);
mesh.SurfaceEnd();
[/csharp]
[/codeblocks]
[b]Note:[/b] Generating complex geometries with [ImmediateMesh] is highly inefficient. Instead, it is designed to generate simple geometry that changes often.
