pub fn Clear(&self, mask: GLbitfield)

glClear (GL 1.0, GLES 2.0)

This sets the bitplane area of the window to values previously selected by ClearColor, ClearDepth, and ClearStencil.

• mask can contain any of the following bits:
  • GL_COLOR_BUFFER_BIT
  • GL_DEPTH_BUFFER_BIT
  • GL_STENCIL_BUFFER_BIT

Multiple color buffers can be cleared simultaneously by selecting more than one buffer at a time using DrawBuffer.

The pixel ownership test, the scissor test, dithering, and the buffer writemasks affect the operation of Clear. The scissor box bounds the cleared region. Alpha function, blend function, logical operation, stenciling, texture mapping, and depth-buffering are ignored by Clear.

Errors

• GL_INVALID_VALUE is generated if any bit other than the three defined bits is set in mask.

pub fn Viewport(&self, x: GLint, y: GLint, width: GLsizei, height: GLsizei)

glViewport (GL 1.0, GLES 2.0)

Specifies the affine transformation of x and y from normalized device coordinates to window coordinates. The window coordinates are computed as follows:

x_win = (x_ndc + 1)*(width  / 2) + x
y_win = (y_ndc + 1)*(height / 2) + y

• x and y specify the lower left corner of the viewport rectangle, in pixels. The initial value is (0,0).
• width and height specify the width and height of the viewport. When a GL context is first attached to a window, width and height are set to the dimensions of that window.

Errors

• GL_INVALID_VALUE is generated if either width or height are negative.

Associated Gets

• GL_VIEWPORT
• GL_MAX_VIEWPORT_DIMS
