Method GL.glTexCoordPointer()

Method glTexCoordPointer

void glTexCoordPointer(int size, int type, int stride, System.Memory pointer)

Description

glTexCoordPointer specifies the location and data format of an array of texture coordinates to use when rendering. size specifies the number of coordinates per element, and must be 1, 2, 3, or 4. type specifies the data type of each texture coordinate and stride specifies the byte stride from one array element 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 texture coordinate array is specified, size, type, stride, and pointer are saved client-side state.

To enable and disable the texture coordinate array, call glEnableClientState and glDisableClientState with the argument GL_TEXTURE_COORD_ARRAY. If enabled, the texture coordinate array is used when glDrawArrays, glDrawElements or

glArrayElement is called.

Use glDrawArrays to construct a sequence of primitives (all of the same type) from prespecified 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.

Parameter size

Specifies the number of coordinates per array element. Must be 1, 2, 3 or 4. The initial value is 4.

Parameter type

Specifies the data type of each texture coordinate. Symbolic constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted. The initial value is GL_FLOAT.

Parameter stride

Specifies the byte offset between consecutive array elements. If stride is 0, the array elements are understood to be tightly packed. The initial value is 0.

Parameter pointer

Specifies a pointer to the first coordinate of the first element in the array.

Throws

GL_INVALID_VALUE is generated if size is not 1, 2, 3, or 4.

GL_INVALID_ENUM is generated if type is not an accepted value.

GL_INVALID_VALUE is generated if stride is negative.
