glscissor
GLSCISSOR(3G) OpenGL Manual GLSCISSOR(3G)
NAME
glScissor - define the scissor box
C SPECIFICATION
void glScissor(GLint x, GLint y, GLsizei width, GLsizei height);
PARAMETERS
x, y
Specify the lower left corner of the scissor box. Initially (0, 0).
width, height
Specify the width and height of the scissor box. When a GL context is first attached to a window, width and height are set to the
dimensions of that window.
DESCRIPTION
glScissor defines a rectangle, called the scissor box, in window coordinates. The first two arguments, x and y, specify the lower left
corner of the box. width and height specify the width and height of the box.
To enable and disable the scissor test, call glEnable() and glDisable() with argument GL_SCISSOR_TEST. The test is initially disabled.
While the test is enabled, only pixels that lie within the scissor box can be modified by drawing commands. Window coordinates have integer
values at the shared corners of frame buffer pixels. glScissor(0,0,1,1) allows modification of only the lower left pixel in the window,
and glScissor(0,0,0,0) doesn't allow modification of any pixels in the window.
When the scissor test is disabled, it is as though the scissor box includes the entire window.
ERRORS
GL_INVALID_VALUE is generated if either width or height is negative.
ASSOCIATED GETS
glGet() with argument GL_SCISSOR_BOX
glIsEnabled() with argument GL_SCISSOR_TEST
