The glDrawRangeElements subroutine lets you specify multiple geometric primitives with very few subroutine calls. Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flage, or color, you can prespecify separate arrays of vertexes, normals, and so on and use them to construct a sequence of primitives with a single call to glDrawRangeElements.
When glDrawRangeElements is called, it uses count sequential elements from indices to construct a sequence of geometric primitives. GLuint start and GLuint end specify the values between which all values in the array indices must lie. GLenum mode specifies what kind of primitives are constructed and how the array elements construct these primitives. If GL_VERTEX_ARRAY is not enabled, no geometric primitives are generated.
The recommended maximum amounts of vertex and index data can be determined by calling GetIntegerv with the symbolic constants MAX_ELEMENTS_VERTICES and MAX_ELEMENTS_INDICES. If end-start+1 is greater than the value of MAX_ELEMENTS_VERTICES,or if count is greater than the value of MAX_ELEMENTS_INDICES, then the call may operate at reduced performance. There is no requirement that all vertices in the range [start,end] be referenced. However, the implementation may partially process unused vertices, reducing performance from what could be achieved with an optimal index set.
Vertex attributes that are modified by glDrawRangeElements have an unspecified value after glDrawRangeElements returns. For example, if GL_COLOR_ARRAY is enabled, the value of the current color is undefined after glDrawRangeElements executes. Attributes that are not modified remain well defined.
The glDrawRangeElements subroutine is available only if the GL version is 1.1 or greater.
The glDrawRangeElements subroutine is included in display lists. If glDrawRangeElements is entered into a display list, the necessary array data (determined by the array pointers and enables) is also entered into the display list. Because the array pointers and enables are client side state, their values affect display lists when the lists are created, not when the lists are executed.
GL_INVALID_ENUM is generated if mode is not an accepted value.
GL_INVALID_VALUE is generated if count is negative or the end value is less than the start value.
GL_INVALID_OPERATION is generated if glDrawRangeElements is executed between the execution of glBegin and the corresponding glEnd.
