GL_GREATER :如果目标像素z值>当前像素z值,则绘制目标像素 GL_NOTEQUAL:如果目标像素z值<>当前像素z值,则绘制目标像素 GL_GEQUAL:如果目标像素z值>=当前像素z值,则绘制目标像素\ GL_ALWAYS:总是绘制 函数说明: 通过目标像素与当前像素在z方向上值大小的比较是否满足参数指定的条件,来决定在深度(z方向)上是否...
Specifies the depth comparison function. Symbolic constants GL_NEVER, GL_LESS, GL_EQUAL, GL_LEQUAL, GL_GREATER, GL_NOTEQUAL, GL_GEQUAL, and GL_ALWAYS are accepted. The initial value is GL_LESS. Description glDepthFunc specifies the function used to compare each incoming pixel depth value with...

GL_GEQUAL Passes if the incoming z value is greater than or equal to the stored z value. GL_ALWAYS Always passes.RemarksThe glDepthFunc function specifies the function used to compare each incoming pixel z value with the z value present in the depth buffer. The comparison is performed only ...
GL_ALWAYS Always passes. Return value This function does not return a value. Error codes The following error code can be retrieved by the glGetError function. Expand table NameMeaning GL_INVALID_OPERATION The function was called between a call to glBegin and the corresponding call to glEnd...
