Calling _cmnd with +.br +_param1 set to +_const(TEXTURE_1D), _const(TEXTURE_2D), _const(TEXTURE_3D) and _param2 +set to the name +of the newtexture binds the texture name to the target. +When a texture is bound to a target, the previous binding for that +target is automatically broken. +.P +Texture names are unsigned integers. The value zero is reserved to +represent the default texture for each texture target. +Texture names and the corresponding texture contents are local to +the shared display-list space (see _cmnd(XCreateContext)) of the current +GL rendering context; +two rendering contexts share texture names only if they +also share display lists. +.P +You may use _cmnd(GenTextures) to generate a set of new texture names. +.P +When a texture is first bound, it assumes the dimensionality of its +target: A texture first bound to _const(TEXTURE_1D) becomes +one-dimensional, and a texture first bound to _const(TEXTURE_2D) becomes +two-dimensional, and a texture first bound to _const(TEXTURE_3D) becomes +a three-dimensional texture. The state of a one-dimensional texture +immediately after it is first bound is equivalent to the state of the +default _const(TEXTURE_1D) at GL initialization, and similarly for +two-, and three-dimensional textures. +.P +While a texture is bound, GL operations on the target to which it is +bound affect the bound texture, and queries of the target to which it +is bound return state from the bound texture. If texture mapping of +the dimensionality of the target to which a texture is bound is +active, the bound texture is used. +In effect, the texture targets become aliases for the textures currently +bound to them, and the texture name zero refers to the default textures +that were bound to them at initialization. +.P +A texture binding created with _cmnd remains active until a different +texture is bound to the same target, or until the bound texture is +deleted with _cmnd(DeleteTextures). +.P +Once created, a named texture may be re-bound to the target of the +matching dimensionality as often as needed. +It is usually much faster to use _cmnd to bind an existing named +texture to one of the texture targets than it is to reload the texture image +using _cmnd(TexImage1D), _cmnd(TexImage2D), or _cmnd(TexImage3D). +For additional control over performance, use +_cmnd(PrioritizeTextures). +.P +_cmnd is included in display lists. +.SH NOTES +_cmnd is available only if the GL version is 1.1 or greater. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is not one of the allowable +values. +.P +_const(INVALID_OPERATION) is generated if _param2 has a dimensionality +that doesn't match that of _param1. +.P +_const(INVALID_OPERATION) is generated if _cmnd is executed +between the execution of _cmnd(Begin) and the corresponding +execution of _cmnd(End). +.SH ASSOCIATED GETS +_cmnd(Get) with argument _const(TEXTURE_BINDING_1D) +.br +_cmnd(Get) with argument _const(TEXTURE_BINDING_2D) +.br +_cmnd(Get) with argument _const(TEXTURE_BINDING_3D) +.SH SEE ALSO +_cmnd(AreTexturesResident), +_cmnd(DeleteTextures), +_cmnd(GenTextures), +_cmnd(Get), +.br +_cmnd(GetTexParameter), +_cmnd(IsTexture), +_cmnd(PrioritizeTextures), +_cmnd(TexImage1D), +_cmnd(TexImage2D), +_cmnd(TexParameter) |
