C glColorPointer glColorPointer glColorPointer: define an array of colors. C Specification void glColorPointer( GLint size, GLenum type, GLsizei stride, const GLvoid *pointer) Parameters size type stride pointer Specifies the number of components per color. Must be 3 or 4. Specifies the data type of each color component in the array. Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT, GL_UNSIGNED_SHORT, GL_INT, GL_UNSIGNED_INT, GL_FLOAT, and GL_DOUBLE are accepted. Specifies the byte offset between consecutive colors. If stride is 0, (the initial value), the colors are understood to be tightly packed in the array. Specifies a pointer to the first component of the first color element in the array. Description glColorPointer specifies the location and data format of an array of color components to use when rendering. size specifies the number of components per color, and must be 3 or 4. type specifies the data type of each color component, and stride specifies the byte stride from one color 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 color array is specified, size, type, stride, and pointer are saved as client-side state. To enable and disable the color array, call glEnableClientState and glDisableClientState with the argument GL_COLOR_ARRAY. If enabled, the color array is used when glDrawArrays, glDrawElements, or glArrayElement is called. Notes glColorPointer is available only if the GL version is 1.1 or greater. The color array is initially disabled and isn't accessed when glArrayElement, glDrawArrays, or glDrawElements is called. 66 Chapter 3
