1991-2006 Silicon Graphics, Inc. glMultiDrawElements 3G glMultiDrawElements render multiple sets of primitives by specifying indices of array data elements void glMultiDrawElements GLenum mode const GLsizei * count GLenum type const GLvoid ** indices GLsizei primcount mode Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES, GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY, GL_TRIANGLES_ADJACENCY and GL_PATCHES are accepted. count Points to an array of the elements counts. type Specifies the type of the values in indices. Must be one of GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT, or GL_UNSIGNED_INT. indices Specifies a pointer to the location where the indices are stored. primcount Specifies the size of the count array. glMultiDrawElements specifies multiple sets of geometric primitives with very few subroutine calls. Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and so on, and use them to construct a sequence of primitives with a single call to glMultiDrawElements. glMultiDrawElements is identical in operation to glDrawElements except that primcount separate lists of elements are specified. Vertex attributes that are modified by glMultiDrawElements have an unspecified value after glMultiDrawElements returns. Attributes that aren't modified maintain their previous values. GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available only if the GL version is 3.2 or greater. GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_VALUE is generated if primcount is negative. GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object's data store is currently mapped. glDrawArrays, glDrawRangeElements Copyright 1991-2006 Silicon Graphics, Inc.
