IBillboardSceneNode got functions to access meshbuffers.
So uv-coordinates can now be modified directly (previously only possible via texture matrix). git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6299 dfc29bdd-3216-0410-991c-e03cc46cb475

--------------------------
|
||||
Changes in 1.9 (not yet released)
|
||||
- IBillboardSceneNode got functions to access meshbuffers. So uv-coordinates can now be modified directly (previously only possible via texture matrix).
|
||||
- vector3d scalar operator/ and operator/= no longer multiply by the inverse but use the expected division.
|
||||
Costs some speed, but fixes floating point troubles caused by this optimization (like x/x no longer being 1.0).
|
||||
- Add equals and set_data functions to core::array for easier working with blocks of data.
