OpenGL的小问题

[柳11]

刚学OpenGL，当使用多重采样和颜色索引的时候，就会出现这种情况，我也到网上查了下，无果！！特来请教各位大神啊，
这里附上代码和问题的描述，劳驾各位呢！！！

刚学OpenGL，当使用多重采样和颜色索引的时候，就会出现这种情况，我也到网上查了下，无果！！特来请教各位大神啊，

不知道那些加行号而且还能复制出来的都是什么狗屎编辑器，这些加行号的代码想帮你调试都无从下手

[柳11]

那我再重发下吧。。。

现在手头机器没有opengl库，先帮你顶下

[fox000002]

这种情况是甚么情况

[柳11]

不懂呢，反正代码什么的没错，库函数也添加呢，也include了，总是这个提示：pixel format with necessary capabilities not found！！！

[ryfdizuo]

lz啊，顶点列表和颜色索引已经十分的out了。
你上这个网址下例子程序看看吧：

[柳11]

只是学习下，应该可以的吧！！！！
