Viewing a plane textured with a smoothed BitmapFileMaterial causes extreme lag #234

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Steps to reproduce the error:

1. Grab latest SVN copy of papervision (version 931 according to tortoise)

2. Create a rotating plane object.

3. Texture said plane with a bitmapFileMaterial that is externally loaded
and has smoothing on (BitmapFileMaterial.smoothing = true) (I am using
transparent PNGs, but have tested and reproduced the behaviour with regular
PNGs).

4. When the plane rotates to either edge on or very close to edge on, the
viewport will seize for an indeterminate amount of time, it will never
actually crash, but it's chugging like mad ...

What is the expected output? What do you see instead?

Expect smooth performance, instead flash seems to lockup when the planes
are viewed edge-on.

What version of the product are you using? On what operating system?
SVN: 931, Windows XP 32-bit

Please provide any additional information below.

When smoothing for the material is turned off, the problem disappears entirely.

OSX does this too, in any browser or the IDE.
It would be great if someone could fix this..
