[osg-users] Texture coords in osgmultiplerenderingtargets.

2012-10-10 Thread Peterakos 
Hello.

in the example  osgmultiplerenderingtargets, why are the texture
coordinates initialized as:

0, 0
tex_width, 0
tex_width, tex_height
0, tex_height

instead of

0,1
1,0
1,1
0,1

(the result is different)

Thank you for your time.

Hi,

That is because TextureRectangle is used and not Texture2D. Look up the 
difference in the OpenGL pages.

Hi most likely, it uses a texture rectangle instead of texture2d, it uses texture coords in pixels. Cheers. 10.10.2012, 16:46, "Peterakos" hay...@gmail.com:Hello.in the example  osgmultiplerenderingtargets, why are the texture coordinates initialized as:0,0tex_width, 0tex_width,tex_height0,tex_heightinstead of 0,11,01,10,1(the result is different)Thank you for your time.,___osg-users mailing listosg-users@lists.openscenegraph.orghttp://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
