Initially, the mask is all 1's. <STRONG>DESCRIPTION</STRONG> <STRONG>fglStencilMask</STRONG> controls the writing of individual bits in the stencil planes. The least significant n bits of <EM>mask</EM>, where n is the number of bits in the stencil buffer, specify a mask. Where a 1 appears in the mask, it's possible to write to the corresponding bit in the stencil buffer. Where a 0 appears, the corresponding bit is write-protected. Initially, all bits are enabled for writing. <STRONG>ERRORS</STRONG> <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>fglStencilMask</STRONG> is executed between the execution of <STRONG>fglBegin</STRONG> and the corresponding execution of <STRONG>fglEnd</STRONG>. <STRONG>ASSOCIATED</STRONG> <STRONG>GETS</STRONG> <STRONG>fglGet</STRONG> with argument <STRONG>GL_STENCIL_WRITEMASK</STRONG> <STRONG>fglGet</STRONG> with argument <STRONG>GL_STENCIL_BITS</STRONG> <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG> <STRONG>fglColorMask</STRONG>, <STRONG>fglDepthMask</STRONG>, <STRONG>fglIndexMask</STRONG>, <STRONG>fglStencilFunc</STRONG>, <STRONG>fglStencilOp</STRONG></PRE></BODY></HTML>⌨️ 快捷键说明
