Member Function Description

void add_sphere ( int lats, int lons, float radius, bool add_uv=true )

Simple helper to draw an uvsphere, with given latitudes, longitude and radius.

void add_vertex ( Vector3 pos )

Add a vertex with the currently set color/uv/etc.

void begin ( int primitive, Texture texture=NULL )

Begin drawing (And optionally pass a texture override). When done call end(). For more information on how this works, search for glBegin() glEnd() references.

For the type of primitive, use the Mesh.PRIMITIVE_* enumerations.

void clear ( )

Clear everything that was drawn using begin/end.

void end ( )

Call this when done adding a batch of geometry, otherwise it can’t be displayed.

void set_color ( Color color )

Set the color that the next vertex will use to be drawn.

void set_normal ( Vector3 normal )

Set the normal that the next vertex will use to be drawn.

void set_tangent ( Plane tangent )

Set the tangent (and binormal facing) that the next vertex will use to be drawn.

void set_uv ( Vector2 uv )

Set the UV that the next vertex will use to be drawn.

void set_uv2 ( Vector2 uv )

Set the second layer of UV that the next vertex will use to be drawn.
