V glVertexPointer glVertexPointer glVertexPointer: define an array of vertex data. C Specification void glVertexPointer( GLint size, GLenum type, GLsizei stride, const GLvoid *pointer) Parameters size type stride pointer Specifies the number of coordinates per vertex; must be 2, 3, or 4. The initial value is 4. Specifies the data type of each coordinate in the array. Symbolic constants GL_SHORT, GL_INT, GL_FLOAT, and GL_DOUBLE are accepted. The initial value is GL_FLOAT. Specifies the byte offset between consecutive vertexes. If stride is 0, the vertexes are understood to be tightly packed in the array. The initial value is 0. Specifies a pointer to the first coordinate of the first vertex in the array. Description glVertexPointer specifies the location and data format of an array of vertex coordinates to use when rendering. size specifies the number of coordinates per vertex and type the data type of the coordinates. stride specifies the byte stride from one vertex to the next allowing vertexes and attributes to be packed into a single array or stored in separate arrays. (Single-array storage may be more efficient on some implementations; see glInterleavedArrays.) When a vertex array is specified, size, type, stride, and pointer are saved as client-side state. To enable and disable the vertex array, call glEnableClientState and glDisableClientState with the argument GL_VERTEX_ARRAY. If enabled, the vertex array is used when glDrawArrays, glDrawElements, or glArrayElement is called. Use glDrawArrays to construct a sequence of primitives (all of the same type) from pre-specified vertex and vertex attribute arrays. Use glArrayElement to specify primitives by indexing vertexes and vertex attributes and glDrawElements to construct a sequence of primitives by indexing vertexes and vertex attributes. Notes glVertexPointer is available only if the GL version is 1.1 or greater. The vertex array is initially disabled and isn't accessed when glArrayElement, glDrawElements or glDrawArrays is called.
