<HTML><BODY><PRE> <STRONG>NAME</STRONG> <STRONG>fglInterleavedArrays</STRONG> - simultaneously specify and enable several interleaved arrays <STRONG>FORTRAN</STRONG> <STRONG>SPECIFICATION</STRONG> SUBROUTINE <STRONG>fglInterleavedArrays</STRONG>( INTEGER*4 <EM>format</EM>, INTEGER*4 <EM>stride</EM>, CHARACTER*8 <EM>pointer</EM> ) <STRONG>PARAMETERS</STRONG> <EM>format</EM> Specifies the type of array to enable. Symbolic constants <STRONG>GL_V2F</STRONG>, <STRONG>GL_V3F</STRONG>, <STRONG>GL_C4UB_V2F</STRONG>, <STRONG>GL_C4UB_V3F</STRONG>, <STRONG>GL_C3F_V3F</STRONG>, <STRONG>GL_N3F_V3F</STRONG>, <STRONG>GL_C4F_N3F_V3F</STRONG>, <STRONG>GL_T2F_V3F</STRONG>, <STRONG>GL_T4F_V4F</STRONG>, <STRONG>GL_T2F_C4UB_V3F</STRONG>, <STRONG>GL_T2F_C3F_V3F</STRONG>, <STRONG>GL_T2F_N3F_V3F</STRONG>, <STRONG>GL_T2F_C4F_N3F_V3F</STRONG>, and <STRONG>GL_T4F_C4F_N3F_V4F</STRONG> are accepted. <EM>stride</EM> Specifies the offset in bytes between each aggregate array element. <STRONG>DESCRIPTION</STRONG> <STRONG>fglInterleavedArrays</STRONG> lets you specify and enable individual color, normal, texture and vertex arrays whose elements are part of a larger aggregate array element. For some implementations, this is more efficient than specifying the arrays seperately. If <EM>stride</EM> is 0, the aggregate elements are stored consecutively. Otherwise, <EM>stride</EM> bytes occur between the beginning of one aggregate array element and the beginning of the next aggregate array element. <EM>format</EM> serves as a 'key' describing the extraction of individual arrays from the aggregate array. If <EM>format</EM> contains a T, then texture coordinates are extracted from the interleaved array. If C is present, color values are extracted. If N is present, normal coordinates are extracted. Vertex coordinates are always extracted. The digits 2, 3, and 4 denote how many values are extracted. F indicates that values are extracted as floating-point values. Colors may also be extracted as 4 unsigned bytes if 4UB follows the C. If a color is extracted as 4 unsigned bytes, the vertex array element which follows is located at the first possible floating-point aligned address. <STRONG>NOTES</STRONG> <STRONG>fglInterleavedArrays</STRONG> is available only if the GL version is 1.1 or greater. If <STRONG>fglInterleavedArrays</STRONG> is called while compiling a display list, it is not compiled into the list, and it is executed immediately. Execution of <STRONG>fglInterleavedArrays</STRONG> is not allowed between the execution of <STRONG>fglBegin</STRONG> and the corresponding execution of <STRONG>fglEnd</STRONG>, but an error may or may not be generated. If no error is generated, the operation is undefined. <STRONG>fglInterleavedArrays</STRONG> is typically implemented on the client side. Vertex array parameters are client-side state and are therefore not saved or restored by <STRONG>fglPushAttrib</STRONG> and <STRONG>fglPopAttrib</STRONG>. Use <STRONG>fglPushClientAttrib</STRONG> and <STRONG>fglPopClientAttrib</STRONG> instead. <STRONG>ERRORS</STRONG> <STRONG>GL_INVALID_ENUM</STRONG> is generated if <EM>format</EM> is not an accepted value. <STRONG>GL_INVALID_VALUE</STRONG> is generated if <EM>stride</EM> is negative. <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG> <STRONG>fglArrayElement</STRONG>, <STRONG>fglColorPointer</STRONG>, <STRONG>fglDrawArrays</STRONG>, <STRONG>fglDrawElements</STRONG>, <STRONG>fglEdgeFlagPointer</STRONG>, <STRONG>fglEnableClientState</STRONG>, <STRONG>fglGetPointer</STRONG>, <STRONG>fglIndexPointer</STRONG>, <STRONG>fglNormalPointer</STRONG>, <STRONG>fglTexCoordPointer</STRONG>, <STRONG>fglVertexPointer</STRONG></PRE></BODY></HTML>⌨️ 快捷键说明
