<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.
