47 adds a new texture target that supports 2D textures without requiring
50 Non-power-of-two dimensioned textures are useful for storing
53 non-power-of-two dimensioned textures. Non-power-of-two dimensioned
54 textures are also useful for shadow maps and window-space texturing.
56 However, non-power-of-two dimensioned (NPOTD) textures have
58 textures. NPOTD textures may not use mipmap filtering; POTD
59 textures support both mipmapped and non-mipmapped filtering.
60 NPOTD textures support only the GL_CLAMP, GL_CLAMP_TO_EDGE,
61 and GL_CLAMP_TO_BORDER_ARB wrap modes; POTD textures support
63 and GL_CLAMP_TO_BORDER. NPOTD textures do not support an optional
64 1-texel border; POTD textures do support an optional 1-texel border.
66 NPOTD textures are accessed by non-normalized texture coordinates.
75 Should rectangular textures simply be an extension to the 2D texture
84 textures do not use [0..1] normalized texture coordinates.
97 Should 3D textures be allowed to be NPOTD?
101 Should cube map textures be allowed to be NPOTD?
107 Should 1D textures be allowed to be NPOTD?
109 RESOLUTION: No. Rectangular textures are always considered 2D
110 by this extension. You can always simulate a 1D NPOTD textures
116 conventional POTD textures will render slightly faster than NPOTD
117 textures. This is particularly likely to be true when NPOTD
118 textures are minified leading to texture cache thrashing.
120 How are rectangular textures enabled?
122 RESOLUTION: Since rectangular textures add a new texture target,
123 you enable rectangular textures by enabling this target. Example:
138 GL_REPEAT, but that mode is not allowed for rectangular textures?
144 for rectangular textures because mipmapping is not supported.
146 Do paletted textures work with rectangular textures?
161 textures because the image is not presented as compressed data and
165 formats for rectangular textures if supported but such support is
170 supported for rectangular textures. This is because several
172 such as S3TC are not designed for compressing rectangular textures.
181 wrap mode remains UNCHANGED for rectangular textures. Clamping of
182 the R texture coordinate for rectangular textures uses the standard
