I have been playing with scaling the texture matrix and I have
come across a weird result on my Linux box running Mesa 3.0
(that doesn't show up on my SGI at work).
The attached program scales the texture matrix (2, 2, 0), and
renders a textured triangle strip with texture coords in the
range [0, 1] (the result looks like I have an identity texture
matrix with texture coords in the range [0, 2] and I have set
clamp.
The resulting texturing gets messed up in area outside the normal
texture (where the CLAMP causes the edge pixel to be "stretched"
across the polygon), but (and this is the good part) ONLY WHEN THE
POLYGON GETS TOO CLOSE TO THE VIEW.
Can anyone else recreate this in current beta versions (I am still
trying to set up CVS at home)? If so, is this a bug or just an
area outside of the spec?
Regards,
scott
