是否有办法检查带有冰川的开放式文字名称是否仍然具有与之相关的有效文本? 在我看到的文件中,有了一个功能性的冰川,但不清楚这一功能是否恢复L_FALSE,如果删除案文的话。
This is... complicated.
如果您在文本名称上打电话到glDeleteTextures,则该名称不再成为案文ure...unless a subsequently calls to glGenTextures re该名称。 参见,一旦你删除了案文,开放式GL可随意在后面使用这一名称。 它像删除一个点;后来的记忆分配有可能完全回到这个点。
All glIsTexture 能够检测到案文是的目前而不是正文。 这可能会再次成为案文。
