TextureEnvMode Enum [fixed]
Posted Monday, 7 April, 2008 - 07:49 by teichgraf in
I am missing the GL_REPLACE value in the TextureEnvMode enum. TextureEnvMode.ReplaceExt = ((int)0X8062) has not the right value for GL_REPLACE:
#define GL_REPLACE 0x1E01
At the moment I use TextureEnvModeCombine.Replace, which has the right value (0x1E01).
GL.TexEnv(TextureEnvTarget.TextureEnv, TextureEnvParameter.TextureEnvMode, (float)TextureEnvModeCombine.Replace);
Is this intented?
Passing a value from the TextureEnvMode enum would make more sense to me, if TextureEnvParameter.TextureEnvMode is used in GL.TexEnv.
Or what did I mistake here?

posted by InertiaConfirmed, TextureEnvMode.ReplaceExt and TextureEnvModeCombine.Replace should both be 0x1e01. The problem could be that they're considered to be different by the generator (ext and core token). Thanks for pointing that out :)

posted by teichgrafWhy is the value named TextureEnvMode.ReplaceExt and not just TextureEnvMode.Replace, like in the OpenGL spec.?

posted by the FiddlerWhich specs?
MODULATE = 0x2100
DECAL = 0x2101
use GetPName BLEND
use EXT_texture REPLACE_EXT
use AccumOp ADD
use SGIX_texture_add_env TEXTURE_ENV_BIAS_SGIX
and:
[snip]
REPLACE_EXT = 0x8062
The only reference to REPLACE comes from StencilOp (which contains the correct value, 0x1E01). Yep, the specs are quite buggy :)
I'll fix this by hand, but it might be a good idea to log a bug at the khronos bugzilla.

posted by teichgrafOK, my fault. With specs I meant the ManPage for gltexenv.

I found a sample that it should be 0x1e01 yesterday. Does this refer to the EXT_texture which was promoted to core in 1.2, or the stencil token? *confused*
