|
+ ImmediateGeometry is a node used for displaying simple geometry created from code, very similar to how glBegin() and glEnd() worked in old versions of OpenGL (1.x).
|
|
|
+ Simply call [method begin()], and add vertices. For custom vertex colors, uvs, normal, etc. call one of the set_ functions below before adding each vertex. When done, call [method end]
|
|
|
+ Calls to begin/end are accumulative and all geometry is added together. To clear all the geometry, call [method clear].
|
|
|
+ If a material override is set, and this material contains a texture, it's possible to override the texture used in this material for every begin/end set of calls.
