void glMultiTexCoord4d(GLenum target, GLdouble s, GLdouble t, GLdouble r, GLdouble q);

PARAMETERS

target

Specifies the texture unit whose coordinates should be modified. The number of texture units is implementation dependent, but must be at least two. Symbolic constant must be one of GL_TEXTUREi, where i ranges from 0 to GL_MAX_TEXTURE_COORDS - 1, which is an implementation-dependent value.

s, t, r, q

Specify s, t, r, and q texture coordinates for target texture unit. Not all parameters are present in all forms of the command.

C SPECIFICATION

void glMultiTexCoord1dv(GLenum target, const GLdouble * v);

void glMultiTexCoord4iv(GLenum target, const GLint * v);

void glMultiTexCoord4fv(GLenum target, const GLfloat * v);

void glMultiTexCoord4dv(GLenum target, const GLdouble * v);

PARAMETERS

target

Specifies the texture unit whose coordinates should be modified. The number of texture units is implementation dependent, but must be at least two. Symbolic constant must be one of GL_TEXTUREi, where i ranges from 0 to GL_MAX_TEXTURE_COORDS - 1, which is an implementation-dependent value.

v

Specifies a pointer to an array of one, two, three, or four elements, which in turn specify the s, t, r, and q texture coordinates.

DESCRIPTION

glMultiTexCoord specifies texture coordinates in one, two, three, or four dimensions. glMultiTexCoord1 sets the current texture coordinates to s 0 0 1; a call to glMultiTexCoord2 sets them to s t 0 1. Similarly, glMultiTexCoord3 specifies the texture coordinates as s t r 1, and glMultiTexCoord4 defines all four components explicitly as s t r q.

The current texture coordinates are part of the data that is associated with each vertex and with the current raster position. Initially, the values for s t r q are 0 0 0 1.

NOTES

The current texture coordinates can be updated at any time.

It is always the case that GL_TEXTUREi = GL_TEXTURE0 + i.
